Loading…Thermostats
Thermostats are used to control heating, cooling and temperature regulation accurately within an installation. They act as the link between the desired room temperature and the operation of the heat source, pump, valve, manifold or control module.
At Hewa, you will find thermostats for heating systems, heat pumps, underfloor heating, contact control and zone control. When selecting the right thermostat, check power supply, switching function, wireless or wired use, temperature range, connection voltage and system compatibility.

Thermostats for accurate temperature control
Thermostats provide the correct control of heating and cooling in homes, commercial buildings and technical installations. Depending on the application, you can choose a simple room thermostat, smart wireless thermostat, contact thermostat or zone control. This makes temperature regulation more comfortable and better aligned with the system design.
Selecting a thermostat for the installation
The right thermostat depends on the heat source, control method and application. In a standard heating system, a simple on/off thermostat may be sufficient. With a heat pump, underfloor heating or multi-zone installation, switching function, response time, control method and compatibility become more important.
Thermostats perform best when they match the rest of the installation. For digital and wireless operation, smart thermostats for heating and cooling are suitable, while contact thermostats for pipe and surface temperature are often used for technical switching. In installations with multiple rooms or groups, zone control for underfloor heating and heating zones provides more control per room.
Important when choosing thermostats
- Check whether the thermostat is suitable for heating, cooling or both
- Check power supply, switching function and maximum switching capacity
- Choose wired or wireless based on installation layout and signal range
- Check compatibility with boiler, heat pump, pump, valve or control module
- Check temperature range, measuring accuracy and room placement
- Use contact thermostats only on suitable pipes or surfaces
- Have electrical connection and control setup checked by a qualified installer
Thermostat solutions by application
Room control
For controlling room temperature in homes, offices and smaller commercial spaces. Suitable when one room or reference area determines the heating demand.
Contact control
For temperature measurement on pipes, manifolds or technical components. Often used for switching points, protection or additional control in heating systems.
Zone control
For installations where several rooms or groups are controlled separately. Especially relevant for underfloor heating, larger homes and commercial projects.
Frequently asked questions about thermostats
Which thermostat do I need for a heating system?
This depends on the boiler, required control method and connection. For simple control, an on/off thermostat may be sufficient. Always check voltage, switching function and compatibility with the boiler.
Can a thermostat also be used with a heat pump?
Yes, but not every thermostat is suitable for a heat pump. Heat pumps often require stable control and proper coordination with underfloor heating, buffer tank, pump or zone valves.
What is the difference between a room thermostat and a contact thermostat?
A room thermostat measures room temperature. A contact thermostat measures the temperature of a pipe, manifold or surface and is often used for technical switching or safety functions.
When is zone control useful?
Zone control is useful when multiple rooms or underfloor heating groups need to be controlled separately. This is common in larger homes, renovation projects and commercial buildings.
Where should a thermostat be installed?
Install a room thermostat in a representative location, not directly next to a window, door, radiator, heat source or in direct sunlight. Correct placement prevents measurement errors and unstable control.
Thermostats for installers and technical projects
For reliable temperature control, the correct combination of thermostat, heat source, heat distribution system and control setup is important. Hewa supports installers and business customers with suitable products for heating, cooling, underfloor heating and technical control applications.
