Frequently Asked Questions
What do I do if my radiator becomes scratched?
You can repair the scratch using a touch-up paint stick in the required RAL colour (RAL 9010 white is the standard colour). Paint sticks are available from your local plumber or merchant, or contact our sales department via mail or phone.
How can I take into account different temperature sets?
Hudevad has created up conversion tables, allowing the required radiator output to be calculated from any specific temperature set. The tables are available under each individual product or in the Downloads section on this website.
What type of paint should I use to paint/re-paint a radiator?
Radiator paint is available as spray paint (in an aerosol can), as liquid paint or paint stick.
The standard colour of our radiators is RAL 9010 white.The procedure for re-painting powder-coated or wet-painted radiators is as follows:
1. Clean the radiator.
2. If the radiator was originally powder coated, use PE powder paint.
3. If the radiator was originally wet painted, use synthetic, non-yellowing paint.
4. The paint should be water-based or a similar acrylic paint.
5. Allow sufficient curing time in accordance with the instructions for the paint concerned.
In which colours are Hudevad radiators available?
The standard colour is RAL 9010 white. To see our colour collections, please consult the colour brochure in the Downloads section. All radiators are available in other standard RAL colours against a surcharge.

What radiator output do I need for my sitting room?
The required radiator output is determined by a number of parameters, including:
- The size of your sitting room.
- The age of your house (sitting room).
- Whether the house (sitting room) has been insulated since it was built (ceiling, walls, floor).
- Whether new energy-saving windows have been fitted.
As a rule of thumb usually somewhere between 30 and 100 W/m2 is required ñ see the examples below. Please note that the data used in the examples is for guidance purposes only!! For more exact calculations, please contact a consultant or a heating engineer.
Houses from the 1960s which have not been insulated since being built:
Required heat approx. 100 W/m2 floor.
Houses from the 1970s or 1980s which have been insulated since being built:
Required heat 50-60 W/m2 floor.
Required heat 25-30 W/m2 floor.
Please note: Hudevad A/S does not perform heat loss calculations.

Yes. Nipple sleeve adapters are available for 3/8” and 3/4” piping.
