How to connect a water heater

Connecting the heater only at first glance seems simple. As in any other case, here there are special features, the observance of which will allow this household appliance for many years to please the owners with good work and hot water. Although there are many recommendations on the vastness of the global Web, a rare article provides all the nuances - one moment is ignored, then the other. We have tried to take this into account and propose a more detailed procedure for the correct operation of the water heater connection. First a bit of theory.

It is known that water is the basis of life. A component of a comfortable life is hot water. It's great, of course, sometimes to visit a bathhouse, but no one will drown it every day, and hygiene rules require just daily bathing. In addition, washing dishes is much more convenient under the tap of hot water pouring from the tap, and not in the basin with dirty liquid. The conclusion is simple - you need a water heater. They can be a gas column or an electrical analog. Let us dwell on the second one, since the connection of a water heater of this type does not require coordination with the services of the gas economy of the locality, in other words, it is cheaper.

In the market there are two types of such devices - flow and storage. Difference in principle of work. The first is heated to the desired temperature passing through them cold water, and the second warm a portion of water, which is then "squeezed out" into a hot water supply system cold. Connecting a flowing water heater is not simpler and not more difficult - it is different. Such devices are very compact and can be installed even in a small room. In accordance with the instructions, mount the water heater on the base - it can be a wall, sometimes the mixer itself. Unlike the heaters of the storage type, the "prototypes" must necessarily be placed next to the point of draw-off. In most cases, the rule "one heater - one tap" is true. We draw a line of cold water to it - this will be the feed. The hot branch should go to the faucet of hot water on the mixer. This is quite simple, and if the pipelines are not of Soviet times, then the work is done in half an hour. The connection of the water heater is complicated by the fact that it is usually necessary to connect a separate power line to it. The power of such devices starts from 3 kW, so they can not be turned on simply into the home wiring outlet - the branches are not calculated for such loads. They draw a new line directly from the switchboard, put the machine gun. It is better for a person unfamiliar with electrical engineering to invite a specialist.

But the connection of the storage water heater (boiler) can be performed independently. Its electric power rarely exceeds 3 kW and then, this is for models with two heaters. Usually 1,2 - 1,5 kW, which is comparable to a modern iron. If the power cord is not included in the kit, then it must be purchased separately, together with a plug. The minimum permissible cross-section of a copper core is 1 mm square. For networks with grounding, a three-wire cable is required. It is advisable not to interchange the phase, zero and earth - this will ensure the correct functioning of the magnesium anode. Connection points are always indicated (to get access to them, remove the bottom plastic cover of the boiler). If the cord is provided by the manufacturer, it is enough to plug it into the outlet.

Important: Do not connect the boiler to the mains until it is full of water. It is recommended to install a separate circuit breaker or RCD for the heater.

The fixture is attached to the wall using dowel hooks. Their diameter depends on the capacity of the tank, but not more than the notches in the mounting plate of the housing. The lower point of the nozzles should be above the mixers.

The water connection is simple - both nozzles are indicated by arrows on the housings and color (blue for cold water, red for hot water). The safety valve from the kit is first screwed onto the supply pipe - it prevents possible damage to the tank body when it is excessively heated.
