The collector for a heat-insulated floor most

To install a water floor is important to observe all the details. Each circuit must be equipped with everything necessary. And one of the important parts of the water floor system is the collector. If you buy a ready-made collector, then this is by far the easiest option. However, you will have to prepare about 20 thousand rubles. If you want to save money, then collect a collector for a warm floor with your own hands. In this article, you will learn how to do this. 

What is its purpose

The collector plays the role of mixing and distributing warm water along several parallel heating circuits. The large cross section and low speed contribute to the effective mixing of the warm and hot coolant, stabilizing the temperature.

Connection diagram is very simple. When the coolant passes through the circuit, it returns to the collector and mixes with the warm coolant. To regulate the ratio of hot and warm water special valves are mounted. Also mounted is a pressure and heat sensor for precise temperature control. Installation does not do without the circulation pump, which increases the pressure in the system.

In the following example, you can understand for what purpose it is necessary to build a collector for underfloor heating:

Example: A boiler is installed in your home. He made wiring for radiators. They require the supply of coolant with a temperature of from 75 ° C to 95 ° C. Also you are planning to install a warm floor. For him, the coolant should have a temperature of 35 ° C to 55 ° C. The floor surface should have a maximum temperature of 30 ° C. Otherwise the floor covering will be damaged. That's just in such a situation can not do without a collector. Indeed, in the contour of a warm floor, you must send the coolant with a lower temperature than in the battery. Moreover, due to the greater length of pipes in a warm field, it is necessary to additionally increase the pressure. For this purpose, a pump is mounted on the collector.

Collector elements

An ordinary collector for underfloor heating consists of the following important elements:

• Three-way or two-way valve.
• The pump is circulating.
• Shut-off and balancing valves.
• Two collectors.
• Thermal head equipped with a temperature sensor.
• To adjust the pressure gauge.
• Air duct Used to eliminate air.

The manifold package also includes nipples, fittings, tees and other elements that play an important role.

The structure of the two-way and three-way valve

Two-way valve has a lower capacity. For this reason, the flow of coolant is carried out without jumps and smoothly. This option is ideal for home no more than 200 m².

Note! Sooner or later, the valve may fail. To make it easy to replace, it is recommended to install an American.

So, the two-way valve operates according to the following principle:

• Thermal head. It will control the temperature of the coolant that enters the circuit.
• When high temperature is reached, the valve opens. After that, hot water does not flow.
• As soon as the water cools, the hot coolant supply opens.
• From the return water flows continuously. Hot, comes only when necessary.

As for the three-way valve, it is considered universal. As a rule, it is used in complex systems. If you have many loops planned, a three-way valve would be the best solution. However, it has a clear drawback, which is the sharp fluctuation in temperature. A hot coolant may be supplied to the circuit if there is erroneous data on the thermostat. The three-way valve has a high throughput capacity.

Note! Often, servos are also mounted on such a system. They are controlled by air temperature sensors or weather sensors.

The three-way valve works according to the following principle:

• This device simultaneously controls the flow of water from the return pipe and the boiler through the bypass.
• Inside this device is mixing hot water with warm.
• The inside flap is perpendicular to the return pipe and the supply pipe.
• When adjusting, you can change the flow rate of the coolant and the temperature level.

Installation of weather sensor

If you want the temperature to be monitored automatically, which reacts to the weather, an additional weather sensor is installed. Although adjustment can be done manually, it is extremely difficult to fine-tune the correct feed ratio. For this reason, this element is mounted. Some weather sensor models have the function to lower the flow rate when you are absent. But such a device will cost more.

The manifold also consists of other important elements, such as an exhaust valve, a temperature sensor and other elements. Each of them performs an important function. At assembly it is necessary to be guided by the scheme.

So, we learned with you that make the collector for a warm floor everybody can.
