How much fan heater size do I need?

With the help of our tool you can estimate the heat output of the fan heater to heat the room to the preferred temperature according to the entered cubic capacity. The calculation method is based on an adapted formula for heat output: Q = V × (Tin - Tout) × k, where V - volume of the room, Tin - temperature inside (desired), Tout - temperature outside (initial), k - heat dissipation factor (from 0.6 to 4).

Variants of room thermal insulation field approximately correspond to: without thermal insulation - walls made of metal sheet or board, poor thermal insulation - walls made of single bricks, standard thermal insulation - walls made of double bricks or foam blocks, improved thermal insulation - walls made of double bricks or foam blocks with additional thermal insulation.
