How to organize heating through a boiler

An electric water heater or boiler for heating is an effective and affordable device for many consumers living in private homes. Of course, the boiler for such purposes is better adapted, but not everyone can afford such a system. For small private and country houses is quite suitable more simple and profitable option. In addition, in some cases, with the right approach to installation, the heating of the living room from the water heater may be no less functional than the boiler.

Types of water heaters

Like all similar equipment, boilers, depending on the energy source, are gas and electric. The second option is most in demand, since the installation of such equipment is not required to obtain special permits, and the cost of such devices will be lower.

With regard to the choice between flow and cumulative, to perform such tasks, experts recommend to acquire and install capacitive tanks. Despite the fact that hot water can be obtained through flow-through devices in a short period of time, such options are rarely used for organizing heating. Is it only in small country houses. It is noted that in this case the spent electricity is not rationally used. In addition, for large living space will require a device of high power, which will not withstand every wiring.

Device and technical characteristics of the boiler for heating

Like a domestic water heater, it consists of external casewhich protects the inner tank from mechanical damage. It houses a mechanical or electronic control system of the device and pressure sensor. Inside is storage tankin which water is stored and heated.The volume can vary from 10 to 500 liters. Small-capacity options are not suitable for heating: the best option for a small area is 200-300 liter devices.

Between the tank and the outer casing there is a heat-insulating layer that minimizes heat loss.

For heating the water in the tank meets the electric heater. Unlike household models, where the heating element has a capacity of from 1 to 3 kW, for appliances installed on the heating system, this indicator should be around 8-12 kW. When choosing a suitable model power must be taken into account. Otherwise, the performance may not be enough to heat even a small room. This will lead to the need for round-the-clock operation of electrical equipment, which will affect both the electrical load and the service life of the heating system. At power choice the boiler should take into account the characteristics of the heated space: the quality of thermal insulation, ceiling height, type of glazing, etc.

Principle of operation of the device simple: cold and hot water have different densities. By entering the tank with a working heating element,cold water displaces hot. The coolant first rises in the tank up, then through the pipes enters the pipes of the system.

To set up heating in your home through a boiler, you need to select and install a model that is suitable for the parameters. Properly selected on the technical characteristics of the device, even when turned on, will periodically go into standby mode and save energy. All heaters are equipped thermal sensors. They turn off the heating element when the water temperature reaches a user-specified level. After it cools, the temperature sensor will again give a signal to the heating elements for heating. This means that the heating system works in automatic mode, it does not need to be permanently turned on and off.

Features of a water heater for heating

Special attention should be paid to the design features of the water heater, which is planned to be used for heating. In conventional storage devices for heating water, hot and cold water connections are located either at the bottom of the appliance (if it is a mounted model) or at the top (if the tank is installed under the sink).Since the temperature of the water at the outlet of the faucet or shower is controlled by the user through the mixer, such an arrangement is very convenient and simplifies installation. In models designed for heating, the inlet for cold water is located in the lower part, and the outlet for hot water - in the upper part. This design allows you to make the device as efficient as possible. In the heating circuit hot water must flow with a certain temperature. And when heated, the coolant in the upper part of the tank just has the maximum temperature mark.

Also, the holes for the nozzles have a large diameter, and are about 4.8 cm each. This is important for the pressure and circulation of the coolant.

Installation of a boiler for heating

Installation of such equipment should be carried out in parallel with the following conditions.

1. In order to minimize heat losses, the room in which the heating equipment is directly installed must maintain optimum humidity and temperature.
2. As a coolant, it is better to use distilled waterand not antifreeze and similar solutions, because water has a higher thermal conductivity.
3. Good electrical network indoors, capable of withstanding prolonged overload.

You can install the water heater for such purposes with your own hands. Each device is accompanied by an instruction that contains explanations and information regarding the nuances of installing the purchased model. Before performing work, it should be carefully examined.

For the circulation of water in the pipeline there are two options:

• increasing pipe diameters;
• use of the pump.

For electric boilers, the second option is best, since the diameters of the hot water outlet are limited. Circulation pump allows you to evenly distribute the coolant on the equipped line.

For more efficient operation of devices, it is necessary to minimize turns and branches, which contribute to a decrease in pressure, and, therefore, affect the quality of the heating system.

System maintenance

To maintain operation and increase the efficiency of the appliances, the heating system must be systematically serviced.The list of mandatory work includes:

• cleaning of the storage tank — sediment accumulates in the process;
• cleaning of the heating elements from the formed scale;
• cleaning or replacing the magnesium anode - this metal rod protects the inner coating of the tank from damage and corrosion.

All maintenance work must be carried out on disconnected equipment.

The boiler for heating can work and cope with the tasks assigned to it as effectively as the boiler. The main advantage of water heaters as a source of heating is an acceptable price.. If you correctly approach the selection of a suitable model and correctly assemble the equipment, then it will not be inferior in quality to the gas boiler.
