The following reasonable assumptions have been made to calculate these approximate daily running costs:
System is installed as a primary heat source in a well-insulated dwelling, built to current Part L regulations.
150W/m2 system under a 10mm ceramic tile on 10mm Insulation Board
Energy price of 14.05p/kWh (average UK price at time of printing)
The system is controlled by an intelligent programmable thermostat with floor sensor
Floor temperatures set at 24 degrees Celsius.
