Running Costs

Greater efficiency can also be achieved by including by:

  • Including a layer of insulation
  • Splitting the heating into different zones
  • Using a programmable thermostat to only have the heating on when you need it

There is a number of factors that will influence the efficiency and the running costs of your underfloor heating. This includes:

  • The set temperature
  • The size and design of the room/home
  • Level of insulation
  • External temperatures
  • Flooring products used
  • Your electricity tariff
  • Length of time the floor heating is on
  • If there is any other heat sources in the room
