Consumption
The average consumption of underfloor heating can be read as a percentage. The thermostat must be on for at least 1 month. To calculate the average consumption per day you can use the following calculation: % x installed power x 24 Example:
Installed power is 300 Watt and consumption is 20%:
20% x 300 Watt = 60 Watt consumption per hour.
60W x 24 hours = 1.440 Watt consumption per day.
Keylock
