Where it is not possible to establish alternative is a later and less dangerous in the fire relation Kitchen electrical analogue. Optionally pick modification with mechanical control means or improved machine which guarantee of security since able to independently shut off the flow of gas if it suddenly turns off or ceases thrust. By the principle of operation of all water heaters are divided into the following types.

flow

The gas flow in the form of modern design is presented as a compact, aesthetic speakers connected to highway. Fits perfectly into the surroundings of the kitchen into the space under the sink, because the assortment of different colors.

The disadvantage of the owners of such devices is generally considered the cessation of supply of heated water as soon as the gas is blocked. Such heaters rescue during planned outages and hot water are excellent lifesaver in the country.

Electric instantaneous water heater for kitchen looks like a box of small size with a tap emerging from it, from which the water enters the desired degree of heating. Such a device is connected to the water system. Running water, passing a heating element receives heat and is used for domestic purposes. Such an arrangement is convenient for placement in a small kitchen, which do not require significant amounts of hot liquid.

savings

This attracts water heater tank construction - thermos preserving the heated water for a long time. Such a variation of the boiler efficiency because the device is turned to adjust the desired volume of fluid to the desired temperature, and then turns off. Gas species are not as compact as they flow counterparts, but have sufficient size range and excellent decor to accommodate under the sink within the most stylish cuisine.

Most of the electric storage water heaters are full automatic boiler, which simply by following the laid down program performs all the basic functions are switched on, heats the water to the required temperature, disabled. Such a device should be connected to the network.

Performance

To storage type water heaters action fully in line with expectations, it should be defined with an average volume of Use warm water and install water boiler, selecting a suitable tank from standardized line:

Volumes of 25 liters could be found, but they disappoint his little performance, so for residential kitchen space, where a large family lives, instantaneous water heaters are recommended, not limited dimensions of tanks.

Power

By purchasing a boiler, you must carefully approach the issue of comparing the power unit with the capacity of existing electrical wiring. In homes with central gas supply, it can not withstand the additional device connection, which on average consumes 3.8 kW. For this reason, only a specialist can make recommendations, if required replacement of communications. If the kitchen is worth electric stove prior consultation would not be superfluous for the possibility of simultaneous inclusion and the heater on full blast.

Relief and check valve

To ensure that the boiler requires any check valve assembly in kitchen water supply system, which is combined with a further safety analogue. Functionality of the last valve - adjusted increase over the water pressure through the bleed water standards. In this case, there may be a slight outflow of moisture, which is normal. The check valve prevents excessive moisture from the water to get inside the cylinder.

Having a large volume of a boiler, it is advisable to provide for the presence of an expansion tank for collecting arising during rising water pressure. It is placed between a portion of finding the relief valve and the water heater.

4. to dismantle mixer hose.
5. Connect the boiler respective layers, providing carrying out sealing, which is often used tow.
6. Laid on the shield with the specified local machine to protect the wiring, equipped with socket and connects the water heater.
