Thermostats with DIVELLO LIQUID H-TECH™ have a fluid-filled sensor element with expansion material that provide a high closing force. DIVELLO LIQUID H-TECH™ reacts faster than wax-based sensor elements and deliberately slower than gas-based sensor elements.

When room temperatures exceed the set value of the thermostat, the volume of the expansion agent increases and the radiator valve begins to close. When room temperature drops, the volume of the expansion agent decreases and the radiator valve begins to open.

Heat from sunlight, appliances and people, etc. is being utilized and proven reaction time ensures that the thermostat does not close too slowly at increased room temperature (e.g. heat from people during visits) or opens too quickly at reduced room temperature (e.g. cool from open windows).

DIVELLO LIQUID H-TECH™ provides stable and precise temperature regulation when it opens and closes the radiator valve depending on the need for heat and with proven reaction time. The high closing force contributes to problem-free use and lower maintenance costs.

Products with DIVELLO LIQUID H-TECH™ are optimizing and energy efficient and are part of the DIVELLO ECONOM product system™.


A radiator system in balance is a basic prerequisite for energy efficiency and good heat comfort.

Radiator valves with DIVELLO STATIC H-TECH™ regulate the flow in the heating system with static and pre-adjustable values. Used mainly in static adjustment when the balancing of the heating system is done manually through carefully calculated and completed pre-setting on each radiator valve.

DIVELLO STATIC H-TECH™ is traditional and proven technology that ensures an energy efficient and problem-free heating system with good heat comfort.
