 Which power output do I need?

  1. New construction – good installation. 35W/m2 – 60W/m2.
  2. Old building renovation – good installation. 60W/m2 – 100W/m2.
  3. Old building renovation – less well insulated. 125W/m2 – 150W/m2.

The specified values are recommended values and apply for comfort heating.

Which Cable do I need?

  1. Determine the room area in m2. e.g. 13.5m2.
  2. Determine the (free) area in m2 to be heated. e.g. 10m2.
  3. Select the total power output required for the area in W e.g. 1,200W.
  4. Calculate the power per square metre: e.g. 1,200W/10m2 = 120W/m2.
  5. Select the product with the nearest total power from the table below. e.g. 121m= 1.215W/230V (121W/m2).
  6. Define the heating cable spacing: 10m2/121m heating cable length = 0.08m (approx. 82mm).
  7. Select your thermostat.
