Servo for heating: the correct installation of the valve, thermostatic head on the radiator, two-way, temperature control

servo drive is an important part of the underfloor heating need to install the servo occurs most often in private homes, which uses a system of "smart house".The servo drive deals with energy saving in heating the room and efficiently distributes energy resources.

valve with actuator: how to choose

servo drives are used in the heating and plumbing systems. They are installed on the collector when installing a warm floor, on the radiators in the room. Thanks to servo drives, the heating system control becomes automatic.

Types of servo drives:

• Open. In the idle mode, they remain open, and when the electric power is supplied, they are closed.
• Closed. In the inactive state are in the closed position, when the power supply is opened. If there is no electricity, the coolant does not enter the system.

Only closed servo drives are used for heating systems. They have a union nut with a thread and can be mounted on standard radiator valves.

Universal servo drives automatically adjust themselves to what mode you want to switch

Today, there are many manufacturers which produce actuators and other components for heating systems and water supply. Which manufacturers are better to say is difficult, because each model has both advantages and disadvantages.

VALTEC and Watts are among the leading manufacturers of servo drives.

REHAU manufactures servo drives for floor heating installation, LUXOR in turn has concentrated on the production of elements for installation in autonomous heating systems.

Installation and operation of servo drives must be carried out strictly according to the manufacturer's instructions - the proper operation of the entire heating system at home depends on the correct installation.

way valve with actuator: General information

main difference between this valve from others is that it passes the water or another composition, in one direction only. The valve is needed to provide control of the water supply and discharge from the system.

If you install it incorrectly, it may go bad or work incorrectly.

The use of a two-way valve with a servo drive makes it possible to regulate the room temperature more efficiently.

There are 2 types of locking mechanism in two-way valves - with a rod descending vertically or with a ball with a hole in the center. All movements are regulated by sensors, and are driven by electric or pneumatic drives.

These valves are made of various types of metal: brass, cast iron, steel.

Cast iron and steel valves are most often designed for a large volume of pumping water or steam. Brass have small dimensions and are used in small buildings and premises.

Before installing the valve, it is necessary to put a filter, this will extend the life of the element.

Progress: how to properly install the thermal head on the radiator

most common connection thermal head is held with the installation of new batteries for heating. As a rule, new radiators are installed before the start of the heating season.

Thermal head installation:

1. In places where the head will be connected to the radiators, make a thread on the pipes using a die.
2. For a part of the pipe that comes out from the riser, you need to fix the counter nut. On it to wind up the sealant for a carving - a fumble.
3. Screw the thermal head, but do not tighten it too much.
4. On the pipe leading to the radiator screw the counter-nut and align it with the head.
5. Tighten the nuts tightly to the pipes - simultaneously clamp them with the help of adjustable wrench.

Installing thermal head for heating the radiator is carried out on the basis of a certain type of heating system

After installing the device, you must check it for correct operation. To do this, first you need to turn on the device to the maximum. Place a thermometer in the middle of the room, observe the temperature rise.

It is important that the thermal head is located in a place where there are no drafts and away from direct sunlight.

After the room temperature rises, turn the valve in the opposite direction and wait for the desired reading of the thermometer, for example 20 degrees. When you see the desired temperature, slowly turn the tap to increase the temperature until water rustles in the casing. On the handle, you can make a note-this position of the regulator corresponds to the optimum temperature.

How to install the thermal head on the radiator: the advantages of the device

thermostatic head on the battery allows you to display and maintain the required temperature for heating the room. The thermal head is mounted on the inlet and outlet of the radiator.

When mounting the thermal head, it is necessary to take into account its location and the position of the head above the valve.

If the head is mounted on the top of a battery, it must be placed horizontally at the bottom of it can be mounted both horizontally and vertically.

fuel economy - one of the advantages of the thermal head

For proper operation of the thermal head is influenced by many factors, so the installation should pay attention to circumstances such as direct sunlight within the reach of the radiator, and other sources of heat( air conditioning orConvector), drafts, temperature on the street.

thermoheads Advantages:

• temperature adjustment;
• Operate at a temperature of 5-27 degrees;
• Uniform heat distribution by radiators;
• Easy to install;
• No additional maintenance required.

Most often, thermal heads are installed in private country houses with an individual heating system. The price of the device is low. Provided that you need to install an element on each radiator in the house, the total cost of thermal heads can pay off during the heating period.

Installation for heating actuator( video)

installation servo principle is simple - two or three-way valve is mounted to the thermostat and the actuator is connected directly to the valve. The device allows you to adjust the heating system at the request of the owner.
