How to connect the water heater to the water pipe in the apartment?

It is difficult to imagine modern housing without hot water. However, not all private houses and new buildings are connected to a centralized network of hot water supply. For this reason, the desire of many people to equip an autonomous hot water supply by installing a boiler is quite understandable. Independently to install an electric boiler, unlike a gas boiler, it is quite simple. How to connect the water heater to the water pipe in the apartment, we will discuss this article.

Types of water heaters

All electric water heaters are divided into 2 groups:

• Cumulative.
• Flowing.

Flowing

A flowing water heater passes water through the heating element in a continuous flow, increasing its temperature. The storage boiler heats the water previously dialed into the tank.

Cumulative:

• A 10-15 liter tank is enough for a small country house without a bath and shower, a washing machine and a dishwasher.
• In a house or apartment with a shower, a boiler with a tank capacity of up to 50 liters is desirable, and for housing with a bathroom - from 80 to 100 liters.

In addition, it is important to place the installation. To do this, you need to know the dimensions of the device, determine the design and be aware of all the nuances of connection.

Special features of installation

Here are the conditions that are required for the quality connection of the water heater to the water supply:

• It is necessary to mount the boiler in such a way as to have access for maintenance of the equipment.
• The boiler can be mounted to a load-bearing wall or partition, which can withstand twice the weight load.

Important! If, for example, the boiler has a tank of 50 liters, then the minimum load that the wall can withstand is 100 kg.

• It is necessary that the wiring can withstand the full load. If the wiring is old, it is advisable to lay a separate powerful cable to the boiler with a grounding wire. It is necessary that the electrical diagram of the installation of the water heater in the apartment be agreed with a specialist, unless you are, of course, "pro".
• Make sure that the water pipes are in good condition. If in doubt, it is better to replace them in advance with metal-plastic ones.

How to connect a boiler in a private house to a water pipe?

So, the whole arsenal of working tools and supplies has been purchased. To independently mount a water heater, no special permits are needed. The procedure for connecting a boiler to a water pipe is a simple matter:

• It is necessary to connect after the water meter. For example, in the place where the valve is installed on the toilet bowl.
• Before you insert the tee to connect the water heater, you must first completely shut off the water supply.
• To create a DHW line, it is necessary to mount a half-inch fitting( after the ¾-inch version) after the valve.

Important! Practice shows that it is better not to save on fittings and purchase good quality fittings. A cheap fitting is unlikely to last more than 3 years.

• On the inlet connection it is necessary to mount a non-return valve, it is supplied in one set with the boiler.
• After the fittings are mounted, you can hang the boiler on the wall and connect the pipes for cold and hot water supply.

Important! Nuts should not be tightened too much, it is better to tighten them when testing the system. At the inlet and outlet of the boiler it is desirable to use reliable ball valves.

After connecting the device to the mains, you can start testing the device:

• Fill the tank with water from the cold water supply system.
• Open the tap on the hot water line to discharge air from the tank.
• Open the hot water tap in the bathroom or in the kitchen.
• After the tank is full, water will flow from the mixer. Now you can close the taps.

It remains to wait a few hours to test the device for leaks. If drops appear on the joints, twist the nuts on the fittings a little.

As you can see, it's quite easy to connect a boiler with your own hands. The main thing is to observe the security measures and do everything carefully, to avoid unpleasant surprises during operation.
