How to switch the boiler to hot water

“Doka-service” service

When the hot water in the apartment is disconnected, there is a need to install a water heater. And if it is already installed, you need to turn it on. The need to use the water heater occurs very rarely, once a year. And which taps to open and which to close. there may be a complication.

When turning on the storage water heater must follow a certain sequence. And to make it easier to remember to use logic.

First of all, you need to close the hot water faucet on the “riser” (common hot water faucet). To ensure that the water heated by the water heater does not “go” into the common pipe. When you turn off the hot water, in the common pipes (“risers”) water remains, but only cold. To do this, you must open the hot water on the faucet to allow it to flow. After what to start closing the hot water tap. Accordingly, the water from the faucet should stop flowing, which will indicate that the hot water is shut off. Water should shut off completely, the presence of drops is not allowed, it will mean that the faucet is not closed completely, and the water from the water heater will go to the “standpipe”.

After that, you need to open two taps on the water heater. First, open the faucet, through which cold water should flow. To make the water “flow” to the water heater. Then a tap through which the heated water from the heater should come out.

It turns out that in order to turn on the water heater, you need to manipulate with three taps. Close the hot water riser tap. so that the heated water does not go into the “pipe”. Open the tap for the cold water inflow into the water heater, open the tap for hot water outflow from the water heater into the “hot” pipes of your apartment. The situation may be different if you have installed a water heater or pipes “super plumber”.

After opening and closing the taps, you must open the water on the “hot” side of the faucet. To get the air out of the water heater, and the water heater goes into its operating state.

And only now the storage water heater is plugged into the socket (or the “automatic” is turned on). If the water heater has regulators and buttons, you need to bring them into working order, and set the recommended parameters for water heating.

Turning off the water heater is done in reverse order. Disconnect from the power grid, closing the taps through which water flows in and out of the water heater, opening a common hot water tap.

If you have difficulty turning on or off the water heater, you can call a master. The price includes departure of the master within Moscow, conducting the necessary checks before switching on, its activation (opening, closing taps).

How to turn off the water heater when they gave hot water, when leaving, for the winter

Seasonal interruptions or complete lack of hot water, forcing users to install water heaters. First you have to figure out how to properly install and connect the technique, and then. how to turn off the boiler when the hot water is given. The connection procedure is prescribed in the manual, and you have to turn it off yourself. Follow our recommendations and you will succeed.

How to turn off the water heater with your own hands

There are different situations when you need to turn off the technology: a trip, start DHW (hot water), repairs. We will consider all possible scenarios, as the complexity of the work depends on it.

Turning off the power while the water is running

You were using the heater while the local water supply was disconnected. Now it has been turned on again, and the appliance is not necessary. Proceed as follows:

  • Unplug it. Turn the knob on the panel to the “Off” position.
  • Remove the plug from the socket.
  • In some cases, it is necessary to disconnect the boiler wiring from the meter.

If there is still heated water in the tank, use it for business or wait until the contents cool down. This can take several hours. depending on the volume of the tank.

  • Turn off the cold water valve so it doesn’t fill the tank.
  • Disconnect the cold hose.
  • Put the hose on the vacant spigot, the other end pointing into a sink or large container.
  • Unscrew the safety valve and open the drain valve.
  • Open the faucet and turn it to the “hot” position.
  • When the water stops flowing, check that there is no liquid left in the tank. Blow into the hose. If you hear a rumbling noise, unscrew the heating element’s flange for final draining.

It remains to shut off the cold and hot streams that lead to the boiler. Open the valve on the riser pipe and use the central water supply.


You are going to bed and do not plan to use the appliance? Thinking of disconnecting it to save power? If the next day you want to get a warm flow, you will have to wait several hours for the heating element to heat the entire volume of the tank. In fact, the design of the device provides for economical consumption of energy. Therefore, the body is equipped with thermal insulation, and the heating is only turned on periodically.

If you don’t plan to use the boiler in the morning, then:

  • For electric models: turn the knob to the left and place it in the last position. Then press the “Mains” button and pull the plug out of the socket.
  • For electronic units: Press the off button on the control panel. Unplug it.
  • Some models (for example, Thermex 1D 50V) are equipped with a timer on. It is enough to set it for a convenient time, so that it starts heating and turns off the device. Users may encounter a problem when “Demo mode” is activated. The heater works, but the flow is still cold. To turn it off, hold down the up and down keys on the panel.

For one week

If you’re going away for a week or two, it’s best not to drain the water so that the tank doesn’t corrode. With the voltage regulator installed, it is enough to press the “Turn off” button on the panel. If there is no stabilizer, disconnect the device from the mains.

For the winter

You don’t want to leave water in the boiler during the winter. First, without heating, harmful bacteria and microorganisms breed in the water. Secondly, if it is unheated dacha and the liquid inside will freeze, the water heater can burst. Therefore, the liquid must be drained and the equipment completely turned off.

After such work, you can even dismantle the product, if you have started a repair or change of equipment.

Now you know how to properly turn off the boiler. Before you start up after the off season, clean the tank with special agents, fill it with water, and then perform the connection.

If there was a temporary stoppage of hot water

And then gave again. in this case you will need to turn off the device, de-energize it, then drain all the water.

The mechanism of switching off for a long period of time:

  • Disconnect the device from the power source by removing the plug from the socket or by turning off the circuit breaker, if an individual circuit breaker for the water heater is installed.
  • If the liquid in the boiler is hot, use it up or wait for it to cool.
  • Unscrew the safety valve and open the “drain valve”.
  • In the bathroom, open the hot water faucet to allow air to flow into the boiler for normal drainage.
  • Next, use a hose to drain all the liquid. When it stops flowing, check that there is no more fluid left in the tank.

By blowing through a hose connected to the cold water inlet of the appliance, if you hear rumbling sounds, the residual water can be drained by unscrewing the heating element.

A heater is a device that makes cold water hot by using liquid, solid or gas fuel and brings it directly to the consumer. The instructions supplied with the unit always contain a detailed description of the connection procedure, and the process of disconnecting the boiler must be carried out by yourself. The following will be more detailed consideration of the actions that need to be taken to properly disconnect the heater.

For the time

There are circumstances when it is necessary to turn off the water heater for a certain period of time:

In these cases, when there is no need for disassembly, no additional tools are required.

To begin with, put the regulator on the control panel in the “Off/OFF” mode, then disconnect the water heater from the mains and perform manipulation with the three taps:

  • shut off the cold water supply to the heater;
  • Close the outlet of the heated liquid from the tank;
  • Open the hot water faucet on the riser, which feeds it directly into the faucet.

TIP! If a small amount of liquid remains in the boiler, but there is no need to drain it if the downtime period is short.

Followed by dismantling

Additional tools will be needed to dismantle the water heater at a later date:

Before beginning disassembly, follow the same steps as for disconnecting the boiler for a period of time. The only difference is that the water from the tank must be drained, for this you must unscrew the valve, remove the hose from the faucet, which supplies cold water, install a rubber hose instead and pour the contents into a specially prepared container or directly into the drain.

The next step is to disconnect the thermostat, the electrical part of the device and remove the heater from its mounting.

Sequence of actions

It is worth mentioning right away that the starting sequence below is true for both flow-through and storage heaters. A couple of nuances. in the case of the first type do not have to wait for the tank to fill with water, and close the tap at the 2nd point.

  • You should start by turning off the hot water supply, which comes from the city’s supply system. If you skip this step, the water heated by the boiler will flow into the common riser, regardless of the check valve.
  • Open the hot water tap. We wait until the remaining liquid drains from the pipes. Close the tap.
  • Two pipes fit at the bottom of the boiler. One, marked with a blue ring, is the underwater, the other, with a red marker, serves to supply hot water pipes.
  • Open the valve on the underwater pipe. Water begins to flow into the appliance’s reservoir.
  • Next, unscrew the second valve on the heater. Allow the water to flow into the pipes.
  • Turn on the hot water at the faucet. Wait until the system is free of air and the water flows in a steady stream. Shut off the water.
  • We connect the heater to the electric network and set the desired temperature mode.

In a house where there is no hot water supply, the first step should be skipped. The next switching on the heater will happen according to the same scheme. The only difference in the 6th point. Then from the tank of the heater will not air, but stagnant water will start to come out.

Selecting the heating mode

Set the heating mode. The main thing in this matter is to set the water temperature comfortable for the user. However, here are a few tips, the implementation of which, will significantly extend the life of the device. Thus saving on future repairs.

  • Set the temperature to 30-40 degrees as infrequently as possible. Under these conditions, inside the storage tank, bacteria will quickly develop. This will result in an unpleasant musty odor. The walls will be covered with fungus, which is difficult to remove.
  • The optimum mode of operation, 55-60 degrees. In this temperature range, less scale will form on the heating element. The risk of mildew is reduced. It is comfortable for human skin.
  • Once a week the water heater should be set to 90 degrees. Wait a couple of hours, and return to the previous mode. This is done to completely kill the bacteria in the storage tank.
  • Some devices have an economical mode of operation. the heater in this case does not consume less electricity. The settings will be set as in point 2 and it is about reducing the risk of breakage.
  • In the case of a heater, flow type, the temperature is also regulated by the head of water.

How to turn the boiler on and off correctly. Sequence of operations

Boiler. an efficient water heating device with a powerful heat exchanger. The equipment runs on electricity and is characterized by ease of operation. turning on and off the water heater is not a problem. True, if the boiler is used as a secondary source of hot water, the peculiarities of start-up and shutdown of the boiler can be forgotten. This happens when people use the water heater only a few times a year, for example, when the centralized hot water supply is disconnected, or when they come home after a half-year abroad. The duration of disconnection can vary from a couple of weeks to several months.

How to turn on and turn off the boiler correctly?

Boiler is a modern equipment of household type, which allows you to be completely independent of the central water supply. It can also be used to provide an uninterrupted flow of hot water in a private home. Such equipment is considered practical and indispensable in the life of every second consumer. This is due to the high practicality of the device with an easy application technology. The boiler is equipped with a simple control system that even a child can cope with. But in the process of operation there may be situations when such equipment must be urgently turned off or on after a long period of downtime. To ensure that the device worked correctly, lasted long and you do not need to repair the boiler, we recommend to take note of some tips.

Instructions for disconnecting the water heater

Before releasing the boiler carry out the following preparatory works.

  • De-energize the unit. The plug is pulled out of the socket or the circuit breaker is disconnected. Take a screwdriver indicator and check the presence of electricity on the contacts.
  • Turning off the water tap in the apartment. If this is not the case, the flow of liquid is stopped by a valve in the basement.

Empty the boiler of water only when it has cooled down. After turning off the electricity you need to wait for the liquid to cool. Then remove the pipes from the boiler, which provides the water supply.

Disconnecting for long periods of time

Sometimes it is necessary to turn off the boiler for the winter and drain the water. Microorganisms breed in the liquid without heating. If the unit is in an unheated building, the water will freeze, the boiler tank will burst. It is recommended that the heater be turned off and removed if the unit is to be replaced or the room is to be redecorated.

  • stop heating by disconnecting the heater from the mains;
  • Shut off the cold and warm fluid inlet faucets going to the unit, the water will remain in the tank and will not drain out;
  • Open the non-return valve on the body.

Sometimes there is an autovalve that provides water to other rooms in a hard wiring condition.

Disconnecting with disassembly

Boiler must be unplugged and removed from partition. Do not dismantle a boiler that has a tank full of liquid inside, you must be sure to drain it to reduce the weight of the tank.

  • close the valve on the hot pipe;
  • Set up a vessel for draining or direct the hose into the tub;
  • Disconnect the junction of the cold riser and the hydraulic safety valve;
  • unscrew the nut connecting the valve to the cold pipe connection;
  • regulate the flow by opening the valve;
  • The water will run out in a few minutes.

It is not difficult to remove the unit if it is placed on hooks. Dismantling requires care not to damage parts.

Turn on and off the hot water

The city mains may come back on, then the boiler can be disconnected if hot water is given. The plug is unplugged and the contents are cooled. You can drain half of the liquid and add cool liquid to make the process go faster.

To drain, close the valve on the cold pipe and disconnect the appropriate socket. Put the hose on the free end and place it in the sink. Unscrew valve and open drain valve. The water faucet is turned to the hot position. Then the supply valve from the city water main is turned on.

How to Reignite a Hot Water Heater : Hot Water Heaters

One of our previous articles on our website is about the need to install a back pressure valve. The valve automatically lets excess water out of the boiler, thus protecting the appliance from pressure on the walls of the tank.

But it is not enough just to install it. Since the quality of tap water is not the best and it has a lot of mineral salts, you need to open the valve every two weeks and forcibly drain the water for 3-7 seconds. This is how you prevent premature clogging of the valve by water sludge and extend the life of the valve. For the same purpose it is recommended to open and close the ball valves several times a month.
