Radiator Thermostats and Smart Heating Control

Short: Thermostatic valves control room temperature by throttling or opening the hot water flow in the radiator as needed. Smart thermostats add automatic schedules and remote control via app to this basic function.

In more detail: Lowering the room temperature by one degree can reduce heating energy consumption by about six percent.

In detail

• Mechanical thermostats: An expansion element reacts to room temperature and automatically opens or closes the valve, without any electricity.
• Smart thermostats: These devices can be programmed via app, learn usage habits, and automatically lower the temperature when nobody’s home.
• Night setback: An automatic temperature reduction at night or during absence saves energy without significantly limiting comfort.
• Room-by-room control: Different temperatures in different rooms, such as cooler bedrooms, avoid unnecessary energy use.
• Correct setting: Thermostatic valves shouldn’t always be turned up fully, since the target temperature is then reached more slowly, not faster.
• Hydraulic balancing: Professional adjustment of the entire heating system ensures all radiators receive hot water evenly.
• Checking compatibility: Before buying a smart thermostat, check the valve size of your existing radiator to avoid connection problems (heizkoerper-entlueften, standby-verbrauch).
