Buying a water heater will provide the user with the constant availability of hot water. In order to achieve efficient operation, it is necessary to correctly install and connect the instantaneous water heater to the mixer. In this case, you must take into account the power of the device, the readiness of wiring, the number of sampling points. How to carry out all the work yourself, we will describe in the article.
Features of connecting a flow heater
There are stationary models that are mounted on the wall and provide several water points with hot water supply: for example, a shower and a washbasin. Water is instantly heated and fed through a mixer. Consist of a housing, a flow heater.
Since the grooves do not have a storage tank, installation is carried out on any wall. Screws or brackets are used.
It is advisable to place the equipment near the fence point. So you reduce heat loss while moving the flow through the pipes.
There are compact models that are mounted on a crane or are a nozzle. Inside them is a heater. Suitable for installation in the sink, for domestic purposes.
How to connect a water heater
There are several connection schemes. Choose the one that suits your needs.
Temporary connection
The easiest installation, for which no tools are needed. This method is used for temporary installations of non-pressure type. Devices will help you out during a scheduled water supply repair, seasonal shutdown. The non-pressure type is good in that it does not require pressure in the line for operation. The main thing is to place the body above the fence point.
To be able to take a shower, unscrew the watering can from the shower hose and screw the hose onto the boiler inlet. If the thread does not fit, use an adapter. A watering can comes with the water heater. Connect it to the hot water inlet.
The manufacturer recommends using the original watering can. The holes in it are located in such a way as to provide a good pressure of water.
Turn the faucet into the shower position and wait 20-30 minutes for water to fill the system. After that, turn on the device, set the desired value on the thermal relay. Keep in mind: the output stream will not always be the same temperature. The technique performs heating at 20 degrees from the original.
Permanent option
Prepare:
- wrench;
- pliers;
- fum tape;
- crane;
- tee.
Stages of stationary installation:
- Connect a tee with a shut-off valve to the inlet pipe of the boiler.
- A metal-plastic pipe or hose is connected to one of the terminals. The latter option is less reliable.
- The other outlet is mounted on a cold pipe.
- When installing, hold the couplings with a wrench so that they do not slip.
- Optionally, you can embed a cleaning filter. It will soften water and reduce the likelihood of scale deposits on parts. How to choose a filter, read in a previous publication.
- On the other exit, install a faucet if the intake point is in the kitchen, or a shower head.
Such a connection can be made using a tee of a washing machine. Connect a shut-off valve to one of the terminals so that the device can be turned off if necessary. Then install a hose or pipe with an inlet to the heater body. Use fum tape to seal joints.
We described the possible options for connecting a pressure-free boiler. To install a powerful device, you will need to prepare a thick section wiring and a ground outlet. Watch the video on connecting the flow device to the mixer:
