How warm water floors work

For 15 years, warm water floors have been successfully used as the main and additional source of heat in residential areas. It is no secret that for the proper operation of this system, when assembling them, it is important to follow the sequence of installation, and for this you need to understand how warm water floors work. In this case, even if you decide to do warm floors with your own hands, you will be able to create efficient heating, which will be an excellent tool in the fight against cold. In this article we will look at the main nodes of water heating, and on what basis they work.

The principle of underfloor heating

Work of a warm water floor consists in pumping over the heat carrier on in advance laid pipes. The heat carrier, as a rule, moves forcibly under the influence of a circulation pump. Heating of the coolant is carried out in the boiler, which can be gas, electric or alternative fuel. A contour is laid in the floor, which consists of a supply and return. Between the heating circuit and the boiler is equipped with a manifold, in which the coolant is evenly distributed over several circuits. Also the collector serves to control and regulate the temperature. When the temperature falls below the set point, the thermostatic valves open and hot water enters the system. When the set temperature is reached in the system and in the room, these valves shut off the coolant supply, and the pump is turned off accordingly. For ease of management, the entire floor heating system works in automatic mode.

Note! Arrangement of a warm water floor collector is the main and best option. However, there are other methods that are no less effective, and in some cases are the only correct solution for organizing floor heating.

Thanks to the collector, you can set a comfortable temperature for the floor. Thus, from the boiler house, the coolant flowing to the collector may have about 90 ° C. The collector has a thermal head with immersion probe, which allows you to adjust the temperature. This is how the desired floor temperature is set, which reaches about 50 ° C. If necessary, the cooled coolant is mixed with the hot one in the required proportion, which the immersion probe regulates. Thus, you are required to simply set the desired temperature, and the system will automatically adjust it.

Note! Additionally, the collector is equipped with flow meters. They indicate the temperature level in each circuit. For example, one circuit can be directed from the collector to the bathroom and bedroom. If you wish, you can adjust the required temperature for a specific room.

To regulate the pressure in the system, a bypass line is used. Thanks to her, in case of an accident, the water will be drained automatically, which stabilizes the pressure in the system.

Heated floor in combination with radiators

In some cases, the arrangement of a heated floor is possible only when combined with a radiator system. So, the main heating will be installed radiators, and in some parts of the room there will be a heated floor. To realize this, there are several options. For example, a T-connector is installed at the boiler inlet / outlet. One outlet is designed for underfloor heating, and the other for radiator.

Note! Floor heating can be easily integrated into an existing radiator system. This is possible thanks to the wireless thermostat, which speeds up and facilitates the installation and connection of the water floor.

We discussed with you the basic schemes of the floor heating. If you understand how this system works, then you will not have much difficulty in installing it yourself. If you have experience in performing such work, be sure to leave feedback. If you have any questions, ask them to our experts.
