When you need to buy expensive household appliances, you always want to protect yourself and choose for sure.
In order not to have to look for services, and every month to buy some spare parts (and sometimes spare parts cannot be found at all), it is worthwhile to study in advance, a storage water heater - which company is better to buy? What customer reviews say.
The storage heater is a heat-insulated container with heating elements inside. It can be of various shapes and sizes. The buyer can always choose the unit for the needs of the family, and the form that is better integrated into the interior of the bathroom or kitchen.
The main difference between storage models is the principle of heating. In the flow version, the water is heated as it enters the device. Accumulative ones pre-heat a large amount of liquid and do not allow it to cool, reheating as it is spent or cools down.
Advantages
If we compare storage models with flow models, then there are a number of advantages:
- There is always a certain amount of hot water available.
- The thermos design keeps the liquid warm for a long time.
- The water temperature will always be sufficient, while flow-through models often fail to cope with the task, simply not having time to warm up cold water.
- The device is less powerful, its operation does not require separate wiring and machines.
- Boilers, lockable with fittings at the outlet, designed for water supply pressure, can be connected to several points of water intake.
The modest power of the units is comparable to ordinary kettles, which makes it possible to connect them to a 220 V outlet. Such unpretentiousness is for many the most powerful argument in favor of a storage model.
When choosing a boiler, pay attention ...
When choosing the volume, according to the number of family members, also keep in mind that it takes more time to warm up a larger volume of liquid. For example, to bring a ten-liter tank to 45 ° C, it will take 30 minutes. It will take 4 hours to warm up a 100-liter tank!
Heating boiler in the interior
In old buildings, where the materials of the walls themselves could already be dilapidated, it is not advised to take wall-mounted options of large dimensions.
In conditions of space shortage in the bathroom, it is not necessary to sacrifice the volume of the boiler, you can choose a model that is placed horizontally under the ceiling.
Electronic or mechanical control
Electronic control, of course, is convenient, elegant and looks solid. But is it really necessary is the question.
Few boiler owners are constantly adjusting temperature indicators. Usually it is simply put up once and used.
The thermal relay successfully copes with this task. But if in the mechanical version there is simply nothing to break, then the electronics are rather capricious, have many elements, and if one fails, this makes the entire structure inoperative.
If your area is experiencing problems with electricity (outage, power surges, etc.), do not chase units stuffed with complex electronics.
Indeed, after the next drop, the electronic device may turn off and not turn on again!
flat or cylindrical
The “weak points” of boilers are their welds. It is here that most often a leak forms over time. Therefore, a tank with fewer seams is preferable. It is better to pay attention not to a flat model, but to a cylindrical one (this form is more durable under pressure, and the price for them is not too high).
Type of heater
There are wet and dry heating elements.
The first one is immersed in the liquid, while the dry one does not come into contact with it.
Marketers, listing the advantages of the latter, note that scale does not grow on it, which means a longer life and no loss of efficiency.
However, on the body in which the heating element is located, scale is still formed.
But cleaning this case is technically more difficult than a conventional wet heating element.
There are a variety of types of water heaters that run on liquid fuel, gas, induction. But the most convenient is the electric option. Consider the selection criteria.
