Thermostatic heads with capillary

Thermostatic heads with capillary are designed for remote temperature regulation in heating systems. These devices allow for precise control of radiator output by adjusting the flow of heated water based on ambient temperature. They are typically used in systems where the thermostat must be located away from the valve, such as in larger rooms or where aesthetics or space constraints prevent placing the control directly on the radiator.

These heads connect to thermostatic valves using a standard M30 x 1.5 thread and are compatible with a range of IVAR valves and compact valve radiators. The capillary length varies between 1 m and 5 m, depending on the model, allowing flexibility in installation layout.

How to choose

• Select the correct capillary length (1 m, 2 m or 5 m) based on the distance between the thermostat and the valve.
• Ensure the connection thread matches the valve or radiator (M30 x 1.5 is standard for IVAR systems).
• Confirm compatibility with the target valve type (IVAR.VD, VS, VCD, VCS, VCR, M-ventil or compact valve radiators).
• Check the temperature range of the head (typically +6.5 °C to +28 °C) to ensure it suits the intended application.

Frequently asked questions

Can these thermostatic heads be used with all IVAR valves?
Yes, they are compatible with IVAR.VD, VS, VCD, VCS, VCR, M-ventil and compact valve radiators with M30 x 1.5 threads.

What is the maximum distance between the thermostat and the valve?
Depending on the model, the capillary can be 1 m, 2 m or 5 m in length.
