How to choose water heaters

The problem with availability of hot water can be solved once and for all, having installed the water heater in the apartment or the house. Now in their market more than it is enough, but that has also put the choice. Some models very expensive, others - are more economical. There are devices big, one may say, bulky, and there are compact. Are available domestic, but also it is a lot of import heaters. How from big variety of offers to choose that device which suits you?

Instruction

1. First of all deal with power supply for the water heater. Some of them work at electricity, for others gas is used. If you have gas-fire in kitchen and there is all necessary system of flues, perhaps, it is worth paying attention to the gas unit especially as its operation costs much more cheaper.

2. The second nuance is your decision on water use. It is possible to buy the flowing heater or accumulative. In the first case cold water from water supply system passes through water heater tubes, and at the exit you receive hot water. In the second case the tank is filled with water, and then heats up. Respectively, hot water if you did not use it, continues to be in tank in the warmed-up state.

3. Considering purchase option, you have to consider the room sizes where there will be your water heater. Flowing devices it is much less by the sizes. They are hung up, as a rule, on wall. Accumulative water heaters take much more places. In certain cases for them it is even appropriate to allocate the certain room. They are as vertical (i.e. are hung up on wall), and horizontal. Some models of horizontal devices can be equipped under washing. But you remember that in that case it has to be with the lower connection.

4. Geysers (instantaneous water heaters) on power are divided into three groups: small (17-19 kW), average (22-24 kW) and high (28-30 kW) capacities. If you use hot water much and in different places, it makes sense to take column more powerfully. Pay attention to way of ignition of column: pyezozazhiganiye or electronic. More conveniently electronic since in this case you discover water – and the column joins. The spark is formed by means of batteries or the minigenerator.

5. The electric instantaneous water heater consumes large number of the electric power since its task is to heat water instantly. Making the choice in its advantage, define for what purposes it will be necessary to you. The device with power up to 8 kW will be suitable for washing of ware and acceptance of shower. For hot bathtubs it is better for you to buy more powerful device (from 13 kW). But installation of such water heater requires three-phase power supply with tension of 380 V that in normal apartments is not provided, so, you should resolve this issue with experts.

6. Accumulative electric heaters of water are economical. Their operation requires the normal socket, but not three-phase network. Hot water thanks to thermal insulation remains long and therefore if you have reduced rate for use of the electric power at night, then you can heat water. Selection of size of tank depends on your requirements. For big family and regular acceptance of bathtub its volume has to be not less than 120-150 liters.

7. Upon purchase of the boiler (both gas, and electric) pay special attention to its protecting cover. Porcelain and enamel cheaper is also not exposed to corrosion. But enamel is sensitive to temperature drop. Boilers with tanks from stainless steel and with titanic sputtering are more expensive, but is more durable.

8. It is important correct to choose the device in terms of thermal insulation. The heat-insulation layer in the boiler, the better is thicker. Take an interest also in the sizes and simplicity of replacement of the magnesium anode (it prevents corrosion of tank inside). The it is more, the more rare it will need to be replaced.

9. It is good if in your boiler it is installed, except the basic, the additional thermostat. It increases safety of the unit. What you bought, be not afraid to ask more about properties of any given device sellers and consult with experts. Only in this case you will make purchase which will not disappoint you.
