How to turn it on
If your apartment or house has a centralized hot water supply, the first step is to turn off the tap that brings hot water into the apartment. This should be done even if there is a non-return valve on the pipe.
- Open any tap, check that the remaining water has drained out of the system, and then close the tap.
- Open the tap on the pipe that comes into the boiler and brings cold water into the machine (this tap is usually marked with a blue circle).
- Open the tap on the pipe that comes out of the boiler and takes out the treated water (this kind of tap usually has a red circle).
- Wait until all the air that was in the boiler is out (the water jet should be even).
- Turn off the hot water tap.
- Plug in the appliance and select the optimal operating mode.
In the following video you can see by example, how to turn on the water heater.
Ignition type
Piezor ignition. the gas is ignited by pressing a button. This method is less convenient than the others, but does not need batteries and has a long service life. Note that the ignition burner never goes out, so the piezo ignition can not be called an economical solution.
Electric ignition (from batteries or mains). gas ignites automatically when you open the faucet. This is more convenient than the piezo igniter, but when powered by batteries, it requires periodical replacement of discharged cells.
Turbine speaker. as in the previous case, the gas is ignited automatically. This type of ignition is used in flow-through appliances.
Do I have to drain the water?
Usually, the remaining water in the boiler is not drained. It remains in the heater until the next ignition, provided the standstill period is short. If you turn off the water heater for several weeks to months, the water must be drained. Otherwise, oxidation or scale formation can occur, which is the cause of reducing the operating life of the water heating equipment.
Be sure to drain the water after the boiler is disconnected from the power grid, it is necessary in poorly heated housing. In a house with low temperatures, water can freeze and rupture the water heater. To remove residual water you should use a check valve. It is located on the body of the equipment.
Using the water heater without water
Without water someone may mistakenly turn on the boiler when they start it up for the first time. However, much more often make this mistake when turning on the boiler in the apartment after a long break. This happens because the water cannot be kept in the boiler for a long time. And when there is hot water at the faucet, the boiler should be kept empty.
It is important not to forget to pre-fill it at the next disconnection of hot water. Before you turn on the boiler this time, you need to make sure that the cold water is getting into it. And then you should open the hot faucet and wait for the water to flow out of it, which means that the boiler is fully filled. To the top!
