Boiler use rules

Without hot water, comfortable living within the walls of any home is not conceived. Fortunately, today accumulative electric water heaters have become very popular. You can learn how to use the boiler and react in case of a possible breakdown from a further review.

What is a boiler

Accumulative electric water heater is a device that gives its users independence from a common heating system. In fact, it is like a big thermoswhich provides long storage of a given water temperature. All this is due to the insulating layer, however, in the design of the unit there are other important components:

• heating element (most often TEH);
• thermostat to adjust the water temperature;
• the tank itself is in the form of a steel tank (enameled inside).

That's just the tank and determines the cost of the device. If all other parts can be easily replaced, then in case of a leakage of capacity it would be best to buy a new boiler.

Safety of use

The water in the boiler water supply system is under constant pressure. A miniature steam bomb - this is another comparison that could not be right, because after boiling the heating element of the device may not be able to withstand pressure. However, an explosion will not occur: there are at least three ways to prevent this in the unit.

1. Thermostat to control the heating element.
2. A thermostat that does not bring water to a point of 90 degrees: it will turn off the heating element and prevent boiling of water. Detail - part of the main thermostat. Usually triggered by the failure of the first.
3. Finally, when both devices fail, a valve is provided that can prevent an explosion. Such an element to work on pressure release (water will flow out, but the structure itself is intact).

Proper operation

There are specific recommendations on how to use the boiler correctly. Their observance will allow to avoid serious damages (many of which are fraught with not only property losses, but also harm to health). Here are the following tips:

• the choice of location for the correct installation;
• optimization of the device;
• damage prevention.

Where to install the boiler

Too long pipe routing has a cooling effect on the heated water. There are certain calculations: 200 ml of hot water is lost from a pipe with a diameter of half an inch: after all, it still has to run to the tap, and for this it has to “push” the already cooled liquid in front of it.

And closing the tap, the user also does not change the situation, because the water remains in the system. How to economically approach this issue? Only optimize the length of the pipeline, successfully positioning the water heater. This ideal place should be between the bathroom and the kitchen. In this case, the kitchen branch experts advise to make the bathroom shorter, since it is in this room that users most often open the tap.

If this option is unacceptable for an apartment,it can be made easier - to insulate the pipes in order to avoid losses. For this you can use, for example, a polypropylene case.

Saving in work of the device

There is another dilemma among the users of boilers about energy saving: the former think that the device should be switched on 24 hours a day, and the latter object that using the equipment only 4-5 hours a day, it’s enough to catch the required hot water in the tank at the maximum temperature . The rest of the time the appliance must be unplugged.

Both are wrong. But how to use the water heater, so as not to "wind" too much? Enough find the exact settings. Many of these units have a knob (usually mechanical) that allows you to do it individually. Here you can recall the Fourier heat conduction law from physics about the difference in temperature of water entering the tank: the smaller it is, the less energy is needed for the subsequent heating of all its layers. Thus, it will be right to set the temperature to 55-60 degrees - this will provide an opportunity to use economically technology around the clock.

And such a measure is effective for the prevention of the formation of scale, which can adversely affect the functioning of the heating element.

In most cases, modern devices are designed in such a way that they are automatically installed. economy mode. For other models, it is easy to do it manually, setting the heating options so that the water does not have to be diluted with cold.

How to prevent problems with the boiler

Current service maintenanceThat will prevent the occurrence of more serious problems. When providing such a service, they usually do the following: they inspect both thermostats and check them for serviceability, clean the tank, and if necessary replace the explosive valve and the corrosion-resistant anode.

The last mentioned detail may be a prerequisite for mud and salt deposits, which leads to the appearance of rust. The last point is already fraught with the destruction of all devices.

It is important to carry out timely cleaning of the heating element from the scale that forms on it - this will increase the thermal heating power and optimize the efficiency of the entire device. Here again, there is a saving in the energy consumed for heating water. You can hold such an event yourself. To do this, follow this algorithm:

• drain water from devices;
• disconnect the equipment from the outlet;
• remove the heating element (TEH);
• prepare a cleaning solution from the proportions of one and a half liters of water to 15 grams citric acid;
• removed heating element is placed in the solution until it is completely clean;
• reassemble the parts and connect the device to the water supply.

Water heater

There are other preventative rules.

1. Turn the equipment on and off only as needed.
2. If there is a daily need for hot water, then the boiler is not disconnected from the network: this way you can prevent it from possible surges.
3. If you leave for more than three days, it is best to turn off the device.

Simple recommendations for using the boiler will allow you to enjoy hot water at any time of the year, without regard to the schedule of heating systems. It turns out that living with comfort is so simple, especially if the house has a serviceable and optimally tuned storage water heater.
