This approximation does not imply any warranty or guarantee of energy consumption and/or electricity costs.

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.
