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.

Actual running costs will vary depending on individual electricity tariffs, specific installation parameters, the level of insulation and heat loss factors of the specific building.
