The arterial indicator is considered the main one in assessing the quality of health of the cardiovascular system and the patient’s condition in general. This is an integral level that takes into account systolic and diastolic numbers.
A range from 100 to 139 by 60-89 is considered normal. Benchmark indicators do not always reflect reality; minor deviations are possible, which is most often observed.
Pressure 100/80 mm Hg. Art. is never considered normal, even though there is no formal rise or fall. Systolic and diastolic indicators are within acceptable limits, but we are talking about something else.
In cardiological theory and practice there is such a thing as pulse pressure (abbreviated as PP). It is calculated as the difference between the upper (systolic) and lower (diastolic) levels. In this case, PP is 20 mmHg. Art. The normal value is about 40.
Insufficient tonometer readings are caused by impaired cardiac output, dysfunction of cardiac structures and other dangerous conditions. Therefore, such patients need to be managed especially carefully.
The situation is insidious; behind the formal norm a deadly pathology can be hidden.
Trouble-shooting
It often happens that due to prolonged or improper use, the boiler fails.
Accordingly, the device requires repair. Before calling a specialist, it is worth determining the cause of the problem, because often many problems can be fixed with your own hands. But someone can safely remove the control panel, disassemble the device and fix the problem, while others don’t even know how to replace a digital temperature indicator. Typically, water heater owners face the following problems:
- the appliance has stopped heating water or is not heating it well;
- the tank is leaking;
- water does not flow well into the tank;
- There was a strange sound during operation.
Every summer, utility workers prepare for the next autumn-winter season and temporarily turn off the hot water.
A water heater becomes a real salvation for a city dweller during the period of scheduled work: just turn off the hot water supply valve and turn on the boiler so that hot water will flow from the tap after a couple of hours.
However, any equipment can malfunction, and a water heater is no exception. Often, when trying to start the boiler again, the user encounters an unexpected problem - the electrical appliance does not turn on when the power button(s) are pressed.
There may be several reasons for this problem, and all of them can be eliminated with your own hands without calling a technician.
First, let's clarify what controls can be on the boiler and what functions they perform.
Buttons on the body of the Termex water heater
As a rule, the following buttons and switches are present on the panel of water heaters (Termex, Ariston, Electrolux, etc.) with mechanical control:
- Mode I - turning on the first heating element;
- Mode II - turning on the second heating element;
- Temperature regulator - when you turn the thermostat knob clockwise, the temperature increases to +75 degrees;
- RCD button (residual current device) - is triggered automatically when a current leak appears on the boiler body.
On the panel of modern models of Ariston storage heaters you can also find additional buttons:
- Eco - when you press it, the system for purifying/disinfecting stagnant water starts. If you leave the ECO button on the water heater turned on, after a certain time (1-2 weeks) the disinfection system will automatically start once a month for preventive purposes;
- FAST - button to turn on the fast heating system. By default the boiler operates at the standard power level. Turning on the Fast button on the Ariston water heater starts an additional heating element, which speeds up the water heating process.
Symptoms that require calling an ambulance or seeing a doctor
The manifestations are caused not only by the decrease in pulse pressure itself, but also by the underlying pathological process.
As a rule, these are cardiac signs; others are also present when the excretory system or cerebral structures are affected.
Sample list:
- Blood pressure 100/80 and headache. They go hand in hand. They mean disruption of the functioning of nerve tissues and blood circulation at the local level. The nature of the discomfort is pressing, shooting or squeezing. Occurs spontaneously, in attacks. The duration of each such episode is from several minutes to a couple of hours, rarely more. There can be many in a day.
- Feeling of discomfort in the chest. The heart turns over, ready to jump out even with a normal rhythm. These are signs of organ dysfunction. What type - you need to look at the ECG. In any case, this is a worrying sign.
- Vertigo or dizziness. From a slight feeling of fog, movement of space in a circle to the inability to navigate even in your own room. Caused by tissue hypoxia, in particular the cerebellum.
- Dyspnea. In a state of complete rest. Develops against the background of tachycardia or other arrhythmias. Accompanied by dissatisfaction with the process. As a result of gas exchange disturbances, a drop in blood saturation is observed.
- Cyanosis of the nasolabial triangle. Blue discoloration of the area around the mouth. Appears as a result of disturbances in the functioning of cardiac structures.
- Paleness of the skin.
- Nausea, vomiting. Repeated, not bringing relief.
- Fainting. This is a dangerous sign and indicates a significant malnutrition of the brain. Syncope can occur repeatedly throughout the day. The logical end is a massive ischemic stroke.
Low pulse pressure may not be accompanied by symptoms at all. This does not mean that the process is difficult or easy. It’s just a feature of the patient’s body.
The signs described above require a scheduled visit to the doctor.

Experienced employees will help you decide on a purchase, offer an alternative option, or select a universal model.
High-quality water heater electronics, the price of which is acceptable to the consumer, can always be found at Ter-Market. Call us and we will solve your problem!
When the question arises about choosing a water heating system, many choose appliances. It has established itself as a manufacturer of reliable, safe devices that are easy to install and operate. Any Polaris water heater provides fast heating and good pressure.
Both flow-through models and Polaris storage boilers are equipped with a reliable heating element. It is in a protective flask and does not come into contact with water. This helps prevent its corrosion. Storage devices are economical; they do not operate constantly, but turn on automatically to maintain the set temperature.
Different models may have electronic or mechanical controls, but all have a display that allows you to monitor water temperature and other parameters. It is possible to adjust the power level.
Additional Information!
The inner walls of the tank are made of stainless steel, and the magnesium anode prevents corrosion. The outer walls have high-quality thermal insulation, which increases its performance and safety.
Most models are wall mounted. They are compact and can have a vertical or horizontal orientation. The design is made in a minimalist style: white body, display and control knobs. The water supply is mainly from the bottom. Flow-through models are equipped with a shower head.
What does a high or low heart rate indicate?
Not much. Heart rate and blood pressure monitor levels are not related. Although the correlation is obvious, it does not exist.
However, the pulse can be used to assess the danger of the process, the need for hospital treatment and the prospects for recovery.
Sinus-type tachycardia (90-100 beats or more while maintaining the correct rhythm and intensifying the work of the natural driver) requires correction of the underlying disease. The acceleration of cardiac activity in itself does not pose a danger.
The paroxysmal type of tachycardia (paroxysmal) is associated with the threat of cardiac arrest and sudden death.
Fibrillation, fluttering, as well as group extrasystoles such as bigeminy and trigeminy, which are recorded during the ECG, provoke a fatal result even more often.
Bradycardia, that is, a decrease in heart rate of less than 60 beats per minute indicates a violation of tissue conductivity or a weakening of myocardial contractility. The prognosis is getting worse.
This is an indirect connection; for the most part, arrhythmias are noted as a result of organic disorders of the heart and blood vessels.
Features of gas connections
When connecting gas stoves, water heaters and other types of equipment, flexible hoses are also used. Unlike water models, they are yellow and are not tested for environmental safety. For fixation, end steel or aluminum reinforcement is used. There are the following types of devices for connecting gas appliances:
- PVC hoses reinforced with polyester thread;
- made of synthetic rubber with stainless steel braid;
- bellows, made in the form of a corrugated stainless steel tube.
The Santekhkomplekt holding offers engineering equipment, fittings, plumbing fixtures and devices for connecting them to communications. The assortment is represented by products and materials from well-known foreign and domestic manufacturers. Discounts apply for bulk purchases, and product quality is confirmed by standard certificates. For information support and assistance, each client is assigned a personal manager. The ability to arrange delivery within Moscow and to other regions of the Russian Federation allows you to quickly receive the purchased goods without unnecessary hassle.
Why does blood pressure become low?
The causes of low blood pressure are very diverse. Factors for lowering blood pressure may be the following:
- professional sports,
- vegetative-vascular dystonia,
- Blood pressure also decreases during pregnancy,
- traumatic brain injuries,
- Possibly low blood pressure due to genetic predisposition,
- Often, a decrease in pressure can be an adaptive mechanism to adapt the body to a new environment,
- hypofunction of the thyroid gland,
- large blood losses.
Installation and connection
Installed device
Modern boiler-type water heaters are mounted vertically. Most buyers prefer this type of structure, as their installation is much faster and easier. Installation using the “open” method is carried out in stages:
- Make sure the location you choose is near an outlet.
- For fastening, use special brackets, often included with the equipment.
- If an optional mount is purchased, make sure it is rated for the weight of the filled tank and will support the suspended structure.
- The instructions for the boiler contain information regarding technical requirements; adhere to the manufacturer’s recommendations.
- Place the drain hole at the bottom.
- Install the safety valve.
- Purchase an additional fuse (valve) in advance; make sure that the hole is always open.
- After installing the fuse, connect the pipes and compression hoses to the sewer system.
- Treat the joints with plumbing sealant.
- Weld the boiler pipes to the general water supply.
- Supply cold water through the ball valve.
- Connect the heater to the power source and check operation.
Popular breakdowns and their repairs
According to customer experience, the most common malfunctions that lead to undesirable consequences and require immediate attention are:
- scale formation on the heating element, which leads to insufficient heating of water or its complete absence;
- thermostat malfunction;
- contamination of the boiler cavity, as a result of which the quality of the water deteriorates, rust impurities and odor appear;
- control board failure, cable damage: leads to the fact that the device simply does not turn on;
- lack of indicator light signal - this happens due to a burnt-out LED or faulty electrical wiring;
- There is a leak in the housing or structural connections.
To ensure uninterrupted operation of the heater, diagnostics should be carried out periodically. Also replace the magnesium anode at least once every 2 years. It is recommended to clean the heating element from contamination once every 3 years. If the quality of tap water is poor, such procedures are carried out much more often: once every 1-2 years.
Forecast

Determined by the underlying disease. 100 to 80 and even a drop in pulse pressure is not an indicator. The problem lies deeper. Negative consequences are associated with the following factors:
- Senile age.
- Cardiac abnormalities of a pronounced kind, organic defects, congenital and acquired defects.
- Pathologies of the excretory system.
- Bad habits.
- Negative family history.
- Severe general anamnesis.
- Poor response to treatment or complete lack thereof.
It is possible to say anything concrete after a long period of observation. The more diseases, the worse the outcome. The severity of the condition is also taken into account.
Answers to frequently asked questions about Termex water heater buttons
All storage water heaters (boilers) operate on the same principle and have a similar design.
This is what the electrical circuit of the most common Termex electric water heater with mechanical control looks like:
As can be seen from the diagram, there is nothing complicated in the design of the device.
- The operation of two heating elements is regulated through a simple control panel, which has heating control and monitoring devices.
- Thermostats installed inside the flask allow you to smoothly regulate the temperature in the range from +7 to +75 degrees.
- When the water in the storage tank cools down, the heating elements come back into operation.
What to do if the Thermex water heater does not turn on?
First you need to determine the cause of the problem. As practice shows, there may be several of them.
Here are the most common:
- The socket is faulty, there is no voltage in the 220 V network. To check this, just connect any other working electrical device to the socket;
- The integrity of the power wires is broken, there is no contact at the terminals of the heating element;
- The on/off button itself is faulty. In this case, replacing the ON/OFF buttons on the water heater
; - The thermal protection button of the water heater
was activated , opening the electrical circuit. Thermal protection allows you to prevent overheating of water if for some reason the thermostat does not work. To start the boiler, you need to press the hidden thermal protection button. It is located directly on the thermostat block; - The residual current device (RCD) has tripped. If the RCD is triggered once, you can reset the emergency shutdown button of the water heater by pressing the red switch located on the device itself. If a repeated shutdown occurs, this indicates the presence of serious defects and the need to repair the electrical appliance.
You can check the performance of the heating elements using a tester (measuring resistance). A damaged heating element cannot be repaired, but you can always purchase a new heating element and replace it.
VIDEO REVIEW
Possible complications
{banner_banstat9}
Outside of therapy or with an insufficiently high-quality regimen, the following consequences may occur:
- Heart failure. As a result of a drop in output, blood stagnation and a decrease in myocardial contractility.
- Stroke. Acute malnutrition of cerebral structures. Potentially fatal condition.
- Heart attack. Necrosis of the muscle layer. Leads to deficiency, dysfunction and lifelong disability. The possibility of death always looms on the horizon.
- Cardiogenic shock. Carries the greatest danger. Even with timely assistance, no one guarantees the patient’s life. Statistics show that death occurs within 3-4 years, which happens less in almost 100% of people. The cause is a repeated episode of cardiac arrest or massive heart attack.
- Vascular dementia. As a result of constant disruption of nutrition of cerebral structures. Forms a clinical picture similar to that of Alzheimer's disease.
The general decrease in quality of life is a “bonus”. All conditions are associated with premature death.
Preventing such an outcome is one of the goals of treatment. It is solved in parallel with etiotropic and symptomatic effects.
Your job is to use it correctly
Having purchased Ariston electrical equipment for your home, do not forget to carefully study the instructions and always have it “at hand”. Following the instructions should in no way be skeptical or underestimated, as it is primarily for your safety. Even if you accidentally lost the instructions for the device, you can get its electronic version specifically for your Ariston model on the official website of the manufacturer
People who create electrical devices check them, test them, put maximum useful information into application and operation manuals with the only important goal - so that you use them correctly. This article will also discuss general requirements and initial information.
Ariston 50 boiler diagram
Boiler designs have approximately the same construction scheme. It contains a housing, a water container (the boiler itself), and a heating element (otherwise known as a heating element, sometimes several of them are included in the package). A magnesium anode must be installed next to the heating element, which prevents the formation of scale. The boiler itself has a heat-insulating layer on both the outer and inner parts.
Two pipes lead to the water heater - one for supplying hot water, the second for cold. Boiler bodies can be cylindrical or flat. The boiler tank can have different capacities - from 30 to 100 liters. The basic principle of operation of a boiler is to heat water in a tank and maintain its constant temperature, set by a person depending on the need.
Types of Polaris water heaters
produces many models that differ in type of heating, volume, control method, and the presence of additional functions. All of them are divided into two large groups: storage and flow.
Flow-through
This type of Polaris water heaters is compact in size. They do not take up much space and are placed on the wall of the bathroom or kitchen. The principle of their operation is that cold water flows through a housing in which a circular heating element is installed. When it comes into contact with it, it heats up and comes out already hot. The degree of heating depends on the power of the device and pressure. In many models you can set a specific temperature - up to 600.
Note! The operation of instantaneous water heaters depends on water pressure. If it is weak, the device will not turn on
Cumulative
The polaris storage water heater is convenient because it provides a supply of hot water. It is collected in a tank, where special heating elements heat it. Moreover, many models have a temperature support function. This provides energy savings when the device heats the water once and then turns on when it cools down. Such devices are available in different sizes.
Thanks to the environmentally friendly internal coating, the water in the tank remains clean and fresh even for a long time. They do not form corrosion or rust. Many models have a filter for incoming water.
Additional Information! Storage water heaters can provide hot water to several water intake points. They do not depend on pressure, so you can install them in your dacha.
10 liters
If hot water is needed for washing dishes or hands, then a tank with a volume of 10-15 liters will be sufficient. It heats up very quickly and maintains its temperature for a long time.
30 liters
This tank volume is suitable for a summer residence. It provides hot water for washing hands, dishes, and cleaning. It is even enough for one person to take a shower.
50 liters
On average, a 50 liter tank is enough to provide hot water to a family of 2 people. It will allow you to shower regularly and use hot water throughout the day.
80 liters
For the needs of an ordinary family of 3-4 people, an 80 liter tank is suitable. The advantages of such a water heater include the fact that it quickly heats the water; you can select a temperature of up to 750. Then it cools down very slowly, allowing you to take a shower or even a bath.
100 liters
To meet the needs of a large family, you will need a 100 liter storage water heater.
You can connect several water intake points to it. This allows you to use hot water in the kitchen and bathroom.
Treatment regimen
Therapy is carried out from several positions and is designed to solve a group of problems.
Eliminating the root cause is the main point, since pressure of 100 to 80 is only a symptom. Here the field of activity is vast, everything depends on the patient’s condition and the underlying pathological process.
A few examples: anemia can be eliminated by the use of vitamins and iron; renal abnormalities require surgery or the prescription of medications, etc.
Symptomatic treatment consists of relief of manifestations. A number of pharmaceuticals are used to restore pulse pressure:
- Antihypertensive in combination with vascular tonic medications. The selection of the regimen is carried out with great care; disturbances in cardiac activity, myocardial contractility and other processes are likely.
- Antiarrhythmic. As needed. Amiodarone as the main one. In a strictly adjusted dosage, no more, to avoid dangerous side effects.
- Cardioprotectors.
- Diuretics are used less frequently.
Smoking and alcohol consumption are contraindicated throughout the treatment. Diet does not play a big role, all doubts are discussed with a nutritionist, and in the absence of the opportunity to consult with him, with a regular attending physician.
Advantages and disadvantages of Polaris storage water heaters
known in Europe, Russia, the USA, the products are also sold in Asian countries, which would be impossible given their poor quality. Heaters have a number of advantages:
-
used for all water supply systems, including autonomous ones with low pressure;
- work in automatic mode;
- it is allowed to connect the heater through a socket (if there is wiring with a cross-section of 3 mm or more);
- low cost, accessible to people of any income;
- convenient adjustment;
- high safety during operation;
- modern design allows you to install boilers, regardless of interior styles;
- 10 liter models available.
List and characteristics of popular models
The manufacturer offers several lines of storage electric heaters, among which the Vega, Gamma, Omega, PM, FD, Ultra, Mercury and Aqua series are in high demand. Each product line combines several model options that differ in a number of technical characteristics.
Series/model | Power, W (max) | Capacity volume options, l | Dimensions, W*H*D, mm | Pressure indicator (max, bar) |
Aqua IMF V | 2500 | 30/50/80/100 | 450*985*310 | 7 |
Gamma IMF V | 2000 | 30/50/80/100 | 550*885*370 | 6 |
PM V | 1500 | 30/50/80/100 | 385*710*385 | 8 |
Mercury IDF V | 2500 | 30/50/80/100 | 450*985*310 | 7 |
Ultra IMF V | 2500 | 30/50/80/100 | 380*898*270 | 7 |
Stream IDF V/H | 2500 | 30/50/80/100 | 380*898*270 | 6 |
Vega IMF | 2500 | 30/50/80 | 809*450*248 | 7 |
All Polaris water heaters are equipped with a remote thermostat. A magnesium anode is built inside the devices, which helps protect the surfaces of structures from corrosive formations. The models presented in the table are positioned vertically during installation.
Since developers constantly introduce the latest technologies into production and use the innovations of technical progress, each of the lines is regularly updated: some models are not produced, moving into the “archive,” and improved versions with expanded functionality are added.
Device differences
PM series design
Electric heaters differ in several qualitative and technical characteristics, for example:
- according to body material: stainless steel or fine glass enamel;
- shape: round, flat, convex, rectangular;
- power: from 1500 to 5500 W (flow devices);
- capacity volume: minimum = 50 l, maximum = 100 l;
- number of modes, additional functions: 1 or 3 modes, “fast heating”;
- location method: horizontally or vertically;
- possibility of electronic control.
Thus, the tanks of most models are made of stainless steel, but the PM series heaters are an exception. For their production, the latest development is used - Italian glass enamel "Colorobbia" of fine spraying. Also, compared to its improved “brothers”, the PM line is distinguished by lower power (up to 2000 W), the absence of an electronic control unit, accelerated heating functions, and there is only one capacity option. The devices are suitable for servicing small country houses, utility rooms, and office premises.
Advantages and disadvantages
Any device has its advantages and disadvantages based on the characteristics, functionality and visual appeal of the product. In addition, when forming the positive and negative aspects of the boiler, reviews of real customers or industry experts are always taken into account.
Oasis water heaters have a number of advantages, including several.
- Quality of indoor and outdoor units. The outer one is made of high-quality steel, and the inner one is equipped with a special enamel coating that provides resistance to temperature changes and also prevents the occurrence of microcracks.
- High level of thermal insulation. The presence of a special layer of polyurethane foam located between the external and internal blocks significantly reduces heat loss in the room.
- Copper heating element, characterized by excellent operating efficiency, which ensures rapid heating of water to the required temperature.
- The presence of a special safety valve, usually hydraulic.
- The presence of a magnesium anode, which minimizes the formation and development of corrosion processes.
- Economical. The boiler heats the cold water that enters it, and then simply heats it up from time to time to maintain the desired temperature and turns off again.
- Easy to use. Most models have a fairly simple heating device control system.
- Safety. For boilers of this brand, all cables are reliably protected.
- The tank model provides only one welding seam, which minimizes boiler leakage areas.
- Special safety sensors ensure uninterrupted operation of the storage heater.
- Long operational period.
In addition, the manufacturer provides a 60-month warranty on water heaters, which only confirms the high quality and reliability of the household appliance.
If we talk about the disadvantages, then these are:
- dimensions - as a rule, water heaters with medium and large volumes have large dimensions;
- duration of water heating - on average, it takes 4 hours to heat 100 liters of water to 70 degrees;
- scale formation on wet heating elements.
If we compare all the pros and cons of the water heater, it is obvious that the device is high-quality and reliable.
Features of electric water heaters
Water heater AquaVerso
Under the Aquaverso brand, the market offers boilers of various volumes and technical parameters, fully adapted to domestic conditions. All of them have a standard configuration, cylindrical or rectangular shape. The devices operate on a cumulative principle.
The design consists of a reservoir placed in an outer, decorative shell. Between the walls there is thermal insulation made of polyurethane foam to keep the contents warm longer. Water from the plumbing system enters the tank under pressure and is heated by the heating element to the set temperature. Heating occurs gradually, which reduces energy costs. The temperature is maintained in automatic mode.
The thermostat controls the switching on and off of the device. For clarity, a power indicator is installed. If the red light is on, it means heating is in progress. After the process is completed, it will go out and the water can be used.
Water heaters are produced with the following tank capacity and dimensions (HxDxW):
- 30 l – 54.6x30x45 cm;
- 50 l – 86x25.5x45.5 cm;
- 80 l – 45.9x44.5x76.8 cm;
- 100 l – 121x29x54.5 cm.
All devices, regardless of volume, have a 1.5 kW heating element installed, which affects the heating duration. So, a tank with a capacity of 30 liters will reach a temperature of +50 degrees in an hour and a half, and for large volumes it will take 3-4 hours.
General characteristics:
- power supply from household power supply 220 V;
- convenient water heating regulator;
- wall installation;
- vertical arrangement;
- maximum heating up to 75 degrees;
- bottom pipe supply for easy installation;
- possibility of connecting several consumers.
For production, stainless steel is used with a varnish coating to protect against corrosion and high temperatures. The internal coating of the storage tank walls is also made of stainless steel. The wall thickness of the internal tank is 2 mm.
A distinctive feature concerns 80 l devices. They can be vertical or horizontal. The internal coating of these models is made of bioglass porcelain.
Trouble-shooting
It often happens that due to prolonged or improper use, the boiler fails. Accordingly, the device requires repair. Before calling a specialist, it is worth determining the cause of the problem, because often many problems can be fixed with your own hands. But someone can safely remove the control panel, disassemble the device and fix the problem, while others don’t even know how to replace a digital temperature indicator.
Typically, water heater owners face the following problems:
- the appliance has stopped heating water or is not heating it well;
- the tank is leaking;
- water does not flow well into the tank;
- There was a strange sound during operation.
If a tank leak is detected, no spare parts will need to be replaced. Here you will need to solder the seams through which water leaks. If there is a leak on the flanges, then you will need to urgently change the gaskets.
If during operation the device produces dirty water and makes strange sounds, then most likely it needs cleaning. First you need to turn off the power to the device, turn off the water supply and remove the lid from the bottom of the tank. They usually come off quite easily. Then you need to disassemble the device. Namely, disconnect the wires and remove the heating element. It can be easily cleaned mechanically or using chemicals. Next, you need to clean the tank itself and thoroughly dry all the parts. Then everything is installed back. Don't forget to turn on the device to check the quality of the work done.
For an overview and installation of the Polaris IDF 50 water heater, see the following video.
What needs to be examined?
Diagnosis is carried out under the constant supervision of a cardiologist. It is possible to involve third-party doctors as needed.
The primary scheme is:
- Oral questioning of the patient regarding complaints. As a rule, there are a minimum of them, and if they are present, they are nonspecific.
- Anamnesis collection. Habits and family history play a big role.
- Measurement of blood pressure, heart rate in combination.
- Daily Holter monitoring using an automatic tonometer. Records the same indicators for 24 hours. Makes it possible to evaluate states over time.
- Electrocardiography. Records arrhythmias of various types and severity.
- Echocardiography. Determines organic defects in heart structures.
- Load tests. Carefully. Limited to bicycle ergometry.
Identification of etiology is possible using other methods. They are shown later if there is no evidence for purely cardiac conditions. Sample list:
- Ultrasound of kidneys, glands.
- Chest X-ray.
- MRI or CT, the former is preferable.
The regimen can be adjusted at the discretion of doctors. This is not a dogma, but just a rough template.
Kinds
Polaris water heaters come in different types and sizes. There is a instantaneous water heater, and there is a storage one. The volume of tanks also varies. It can be 10, 30, 50, 80, 100 liters and even 150.
Storage water heaters from this company are available in volumes from 10 to 150 liters.
As a rule, such models can withstand pressure up to eight atmospheres. The design of such devices also has its own distinctive features. For example, storage models can be easily connected to a regular outlet, which is very practical.
As for the time it takes to heat up, it all depends on the model and volume of the tank. Typically, the first heating after installing the water heater takes at least half an hour. Afterwards, the heating element will turn on when the water temperature drops. This way, there will always be hot water in your home's tap. This heating method also helps save energy.
In addition, storage tanks are equipped with high-quality heating elements and have excellent thermal insulation, thanks to which they heat water as quickly as possible and keep it hot for a long time.
When choosing a storage model, it is worth considering the fact that you need a separate place for its installation.
If you only need a water heater for washing or washing dishes, then a tank with a volume of 10-15 liters is the best option. For regular showering, the volume should be at least 30 liters, on average 50. And for those who are used to taking baths frequently, it is worth purchasing boilers with a volume of 80 liters and above.
Another type of water heater is instantaneous. Its main difference is that it is able to heat water to the desired temperature in almost a matter of seconds. Cold water, before entering the tap, passes through the heating element and, immediately heating up, pours out of the shower or tap.
Flow models are divided into two types: pressure and non-pressure.
The first option is in great demand. Such models are mounted in the risers themselves, which saves space in any room. Their only disadvantage is that they cost much more than non-pressure ones.
