Underfloor heating and room thermostats are controlled through a relay (on/off) signal. The relay is being activated with a varying duration when heat is requested.
At a high heat request level or high intensity heating, the relay is closed for a longer time than for a low heat request level or low intensity heating.
This is data is summarised as Consumption data in the Themo webapp and displayed as graph.
Consumption is calculated from how long the relay has been activated and is then multiplied by how much electrical power has been applied to the heating system.
Themo has built in capabilities to estimate the power level of your direct electrical heating. For hydronic based systems the calculation of power consumption may be inaccurate. If the underfloor heating is behind a separate relay, the automatically calculated power reading may be incorrect (usually 100W). In this case, please make a support request to our customer service.
- I think that the real power consumption is higher / lower than Themo is showing, what can I do?
- Electricity contracting and consumption history.
