The following reasonable assumptions hare used for these estimations:

  • Heating system is installed in a house built and insulated to current regulations
  • Floor temperature set to an efficient 22C
  • a DEVI thermostat has been installed
  • Heating system is under a 10mm ceramic tile and on 10mm insulation board

PLEASE NOTE: Actual running costs will depend on several factors, including insulation of flooring, room plus heat loss factors of the specific building. This information is a guide only and does not imply any warranty or guarantee of energy usage, consumption and/or electricity costs.
