The mixing unit for floor heating - Collector: purpose, structure

on well-being, which is indoors, greatly influenced by the prevailing temperature.The optimum temperature for the person in a residential area at the height of the growth is 19 - (20) degrees Celsius, near the floor 22 - (25).The best solution in this case is the underfloor heating system, which is considered an important part of a mixing unit for floor heating.


Purpose mixing sets ↑

mixing unit is used inheating.Typically, boiler heating system supplies water at a temperature of about 70 - 90 degrees above zero, because that's what this figure is needed for radiator heating.But the system of water underfloor heating is a low temperature heating system that requires a coolant temperature that reaches 25 - 35 degrees.

mixing unit and is intended to reduce the water temperature by mixing hot medium heat with the return - the liquid that came from a he

ater and give warmth.Units are equipped with all the mixing valves, units and other elements that manage and control the temperature regime.Also

systems underfloor heating mixing units are widely used for the organization of radiant heating - wall and ceiling, as well as for heating greenhouses and open areas.However, the collector for water sex more often used to stabilize the temperature of the fluid in the pipe in the floor heating in residential areas - in their own apartments and private houses for one family.

design control valves ↑

collector for warm water floor consists of the following parts: the control valve (the valve), the circulating pump, the electric control valve, ball valve, check valve, filter, balancing valves and other fittings.

What part of the mixing unit
As part of the mixing unit

mixing unit, as mentioned above, is intended to mix with water from the return line.Regulation committed valve that is installed in the supply reservoir and thermostatic head that has a remote immersion sensor.Balancing valve, which is in the mixing line, sets the optimal ratio of the coolant, which comes from the forward and reverse link.

collector for underfloor heating can be further staffed zonal thermostats and other measuring instruments, air vent and drain valve to drain the water.A wide range of devices allows you to accurately calculate the energy by installing the heat meter.

as material for control valves used brass and bronze for pipes - neozinced black steel, housing - cast iron.Sealing is accomplished with the use of flax.The absence of the zinc coating allows the mixing units where used as coolant water glycol entering into reaction with zinc.

principle of operation of the mixer ↑

pump runs constantly and provides a current of coolant in the tubes and the valve passes at the right time the required amount of hot water programmed temperature.This achieves the necessary level of temperature of the water floor heating.

Adjustable only the amount of coolant, so the underfloor never overheat and rupture construction impossible.Small capacity of the valve provides a stable, very smooth control of the room temperature.

It is important to know!The temperature of the floor is of two kinds - comfortable and heating.The system water sexes in the first case creates comfort in the housing and energy consumption of heating does not occur, this is achieved by means of additional heating elements.In the second embodiment, like the floor also performs a heating element, and the heating rate will be significantly higher.

Mixing units are installed in the collector cabinet at the beginning of the installation of underfloor heating.Possible as the left-sided and right-sided installation of the mixing unit.You can also conduct covert installation.

Types mixing sets ↑

mixing units for water floor heating divided into several types.If you bought an individual collector, it should be remembered that it is connected to only one user.If you select individual group nodes, they will connect the consumer increased power.It is also possible to connect several consumers with lower power.

In the domestic market are presented and main mixing units for the connection of several consumers, who are characterized by large capacity.Buyers are also offered heat transfer model.Low power consumer is connected in a closed circuit.There are models with different number of outputs - from two to twelve.

Control options: differences ↑

  • manual control is accomplished as follows: mixing unit is used without the valve, manually set the percentage of the mixing.But such a collector for water floor heating is not common to use for high-temperature heat source, when the maximum flow temperature is over 50 degrees.
  • management mode limit temperature is as follows: on the way valve must be installed thermostatic head with remote sensor type.The circuit floor heating temperature is limited according to the set temperature on the head, which is sold separately.

Modifications of control valves for underfloor heating with different management principle
  • Office for the outdoor temperature is carried out under the scheme: on way valve must be installed electric drive, connected to the thermostat.The underfloor heating circuit temperature is adjusted according to the temperature changes in the street.Power and control are supplied separately.

So, if you decide to install a warm water floor, you should think about buying a mixing unit, which will help to reduce the water temperature by mixing hot liquid from the tank line.The market presents different models, it depends entirely on the requirements of the heating system.
