mix with unit for underfloor heating

Heated floors - this is hygiene, safety and comfort in the house.

They are economical, can automatically adjust the heating temperature, but despite this they need thermoregulation, which is used to mix with the node floor heating.

After heating system, to which usually connect underfloor heating system is heated to 60-80 ° C, while the normal floor heating, the heating temperature should not exceed 35-40 degrees.

Otherwise - overheating of floor heating surface begins to crack the flooring and furniture, and the room is stuffy and not so comfortable.

Standard mixing unit for floor heating consists of:

• built-in thermostatic valve manifold;
• thermostatic head with remote sensor;
• circulation pump;
• temperature limiter;
• control valve;
• built-in thermometer.

mixing units are of two types: on the three-way and two-way valves.

way valve mixes the hot water inside with chilled water, which is fed back from the underfloor heating system.

But such valves have a very large capacity, why are completely open and flowing into the hot water system.

Such sharp temperature jumps are undesirable because of the increased pressure can occur pipe rupture.

three-way collectors, despite their drawbacks, are indispensable for climate control systems and for the installation of underfloor heating in rooms with a large area.

In small rooms it is advisable to establish two-way mixing units for warm water floor heating systems.

Such a mixer immediately mixes hot water with cold water that comes back from the underfloor heating system.

Thus, the water is constantly circulated, without giving a warm floor to overheat.

mixing unit is installed in a special collector cabinet to the floor heating system installation.

Installation mixing sets can be right or left.If the node type of mix with spoil the interior, it can hide.

Buying and setting

When buying a mixing unit for floor heating know that they are of several types.

example, to an individual collector can be connected to only one user, and mix with a group of individually-node is designed to connect high power consumers.

In the domestic market there are also mixing units, which can connect multiple users with a small capacity, there main mixing units with a large capacity, there are different models of units with different numbers of outputs - from 2 to 12.

From this it follows that the collector is easy to purchase, choose the right mix with the main site for the floor heating.

Price mixing unit sometimes bite, depending on the manufacturer, the "stuffing" of the collector, the type of equipment and its capabilities.

But the market can find and quite cheap model or make a mix with the node itself.

Despite the high cost, it is best to install the factory site to mix with underfloor heating.You can buy it in stores or plumbing in the building markets.

If your city is not commercially available mixing units for underfloor heating, they can be ordered from specialized companies.

should determine the number of connections Before buying a collector.

For example, you need a mix with node 8 connections, and are commercially available mixing units only 6 connections.

In such a case would have to separately purchase additional comb and use them to connect the two missing contours.

Do not forget to look at before buying a complete set of the mixing unit, which must be present flow sensor or flow meter, mounting, bleed and drain valves.

If necessary, purchase additional equipment: room temperature sensors, actuators, and mix with the modules.

Some people ask, how to configure the node to mix with warm floor?Setup and installation of mixing units must be carried out according to the instructions, which certainly included with the product.

As mentioned above, the mixing unit design consists of a three-way or two-way mixing valve, temperature sensor, circulation pump and check valve.

When installing unit mix with, first on the inlet pipe and install a circulation pump temperature sensor.

Next - to warm the heating system pipe attached mixing valve.Return valve mounted on the outlet pipe.

Exit check valve connected to the cold pipe heating system and discharged to the mixing valve.

Do a trial run of the system of underfloor heating and check the temperature level.

If the temperature is not enough or too high, then increase or decrease the valve capacity, or adjust to the desired temperature sensor.

Making mixing units with their own hands

Many home craftsmen think, why buy an expensive mixing unit, if its design is so simple that they can easily do it yourself.not so simple here.

If you do not have the locksmith skills and have never had to deal with heating, but still are serious, then mixing units for the warm floor with your hands is best done at the exact step by step instructions that you can find on the internet.

to mix with the assembly site, you will need a thermostatic valve and connection fittings (flare nuts, check valve, tees, thermometer, nipple, pump, ball valves, etc.).

mix with standard unit for floor heating is done with his own hands from the thermometers installed in the supply and return valve.

They control the temperature of the coolant and when returning serve.Circulation pump is needed to maintain a water circulation system piping.

Manual air vent is used to remove air from the system.Bypass is set to adjust the heating temperature.Still needs some filling the water drain valve.

If the water pressure in the system exceeds the permitted limit, this valve will prevent pipe rupture.
