Connecting a warm floor to the boiler

For heating a house located outside the city, various heating systems are used; in recent years, a "warm" water floor has been increasingly installed. The owners of such houses will not interfere with certain knowledge regarding the connection of this device to the boiler. This knowledge will be useful either for self-installation of this heating system or for monitoring workers who will perform such a connection.

Features of connecting underfloor heating to the boiler

The floor heating system provides comfortable microclimatic conditions in the house. After the warm floor is laid, it will be required to connect it to the boiler installed in the house. Such a connection is made through a collector. Installation of underfloor heating is carried out in rooms with high humidity.

IMPORTANT! According to individual experts, the optimal system of heating is considered a complex of a dual-circuit boiler and connected to it a "Warm" floor, and the boiler is suspended.

The simultaneous operation of the boiler and the underfloor heating is able to provide the necessary amount of heat at home. Such a system will eliminate the use of other types of boilers, for example, electric.

The "warm" floor must be connected to the boiler, through collector. What it is? So called a device that is designed for uniform distribution of the heated working medium to consumers connected to the boiler and due to the circulation of the working fluid, through it it is returned for heating.

After selecting a collector, it is required to be connected to the boiler. To perform this operation, you must strictly follow the requirements of the operating instructions for both units of products.

Connection diagram of the underfloor heating collector

There can be several ways to connect. It depends on the type of boiler and its location. However, in all cases certain conditions must be met. It is better to connect the warm floor to the boiler according to the existing scheme. For example, such.

Subtleties of installation

The location of this component of the heating network directly depends on the decision that the homeowner will make. In principle, it can be installed anywhere, the main thing is that it does not interfere with anyone and be out of reach of children. But, one way or another, there are recommendations that will not be redundant at all:

  • The cabinet for installing the collector device must be installed in a room where access to the piping lines will be provided.
  • To the ends of the pipes connect the side fittings of the collector device. Through them, direct and reverse supply of the coolant will be carried out. It is advisable to install the necessary valves and temperature controllers.
  • To simplify the procedure, it makes sense to buy a manifold ready for installation, the kit of which includes stop valves. These units, which will be mounted on the findings of underfloor heating, radiators and other heat consumers. During operation of the heating network, the homeowner will be able to turn off certain circuits of the heating network, but some of the circuits will continue to work.
  • The ends of the pipes, valves and the manifold are connected using fittings. Quite often, the output pipes of the heated floor are connected to the collector by using connecting nodes consisting of a ring equipped with a clamp, a sleeve and a nut made of brass. There is a simpler connection method., which is based on the use of simple clamps, which are equipped with shut-off valves.
  • Heat supply pipes and return pipes are connected to the inlet to the coolant distribution device, and the heated floor pipes to the outlets.

Connection Elements

A complete set of the collector assembly consists of:

  • shut-off valves;
  • knot mix;
  • drain tap;
  • pump to provide movement of the working medium.

In the process of connecting the collector and the elements of the heated floor with the boiler, the locking devices can be replaced by a valve with an installed thermostat. The main advantage of such a device lies in its ability to resize, in accordance with the temperature regime. After passing through this device, the coolant will receive a certain intensity of movement.

Connection Order

As already noted, the optimal heating system can be considered a set of equipment consisting of:

  • boiler;
  • underfloor heating;
  • collector;
  • necessary binding.

The connection of the listed components should be carried out in a certain order:

This work is carried out in a certain sequence:

  1. Selection of the connection place. As usual, before connecting the heating equipment, it is necessary to prepare the premises. That is, it must have a flat floor, equipped with a drainage to remove water that can go into the room as a result of a breakthrough. Of course, lighting should be established in it. The dimensions of the room should provide free access for personnel to service the installed devices.
  2. Direct and return pipelines are brought to the collector. The return will take chilled water, and redirect it to heating. Through a direct pipeline, the coolant, heated to the specified parameters, will be directed to the heating network.
  3. The boiler pipe is connected with a valve, fittings are used for this, and then it is included in the collector.
  4. At the ends of the pipes, taps and temperature controls must be installed. They are designed to regulate the movement of the coolant along the contours and, if necessary, for example, an emergency, disconnecting damaged lines.
  5. The final operation is to test the assembled system.

Expert advice on how to properly connect a heated floor to a heating system

There is no single document on the technology of assembling the collector assembly and connecting the underfloor heating to the boiler. But the principle of action is the same. Meanwhile, there are certain rules that it makes sense to observe when performing these works.

For example, an expansion tank must be installed above the circulation pump. The installation location of this pump is not so critical, but experience has shown that it is desirable to install it at the highest point in the heat system.

We must not forget that to increase the insulation of compounds, a fluoroplastic tape or thread should be used.
