Thermoelectric actuators play a vital role in modern underfloor heating systems, providing precise control over individual heating circuits. These small but powerful components are particularly important when managing systems with multiple loops that control different heating zones. Here’s a deeper look at how they work and why they matter in your installation.
What is a Thermoelectric Actuator?
A thermoelectric actuator is a device designed to open or close heating valves in response to signals from a thermostat. These signals are typically transmitted via a wiring control box, prompting the actuator to open a valve, which allows warm water to flow through the specific underfloor heating loop. This individual control is key for ensuring each zone in a home or building receives the desired level of heat.
The actuator contains a wax element that expands when it receives a signal, triggering the valve to open. This ensures a smooth and reliable operation, making thermoelectric actuators perfect for systems that require efficient heat distribution across multiple areas.
Key Features and Technical Data
Here’s a quick overview of the technical specifications for our thermoelectric actuator:
- Supply voltage: 230V
- Permanent power absorption: 1W
- Time of closing/opening: 3 minutes
- Nominal stroke: 4mm
- Ambient temperature: Max 60°C
- Power cable: 2 x 0.75mm², 0.8m
These features ensure energy efficiency, reliability, and longevity. The actuator uses very little power (only 1W), and its controlled opening and closing time (3 minutes) ensures a smooth transition between on and off states.

Assembly and Installation
Thermoelectric actuators are installed on the thermoregulation valves located on the manifold’s return beam. Installation is straightforward, utilizing a standard M30 x 1.5 nut (which is part of the valve assembly). Here are a few quick installation notes:
- Attach the actuator to the thermoregulation valve on the manifold’s return beam.
- Use the standard M30 connection to secure the actuator in place.
- Ensure proper wiring to the control box for seamless communication with the thermostat.
Why Use Thermoelectric Actuators?
The precision control offered by thermoelectric actuators is crucial for efficient and comfortable underfloor heating. They allow control of heating in multiple zones independently, ensuring each space maintains its ideal temperature without wasting energy. This is especially beneficial in homes or buildings with complex heating requirements, where different areas may have varying heating needs.
By using thermoelectric actuators, you improve energy efficiency, optimize comfort, and extend the lifespan of underfloor heating system. They are an indispensable component for any underfloor heating installation aiming for top-tier performance and flexibility.
