Wickes universal radiators
- over 60 sizes up to 1600mm wide

Our range of single universal panel radiators, Double Plus Radiators and Double premium radiators features over 60 sizes up to a width of 1600mm.

The unique 3-in-1 design

All universal radiators feature an innovative 3-in-1 design allowing three options that will fit into any room setting.


High quality/high standards

Manufactured in the UK from high-quality, locally sourced cold rolled steel with a nominal thickness of 1.2mm, universal radiators undergo an intensive pretreatment process to protect against rust. They are then finished to high quality standards with Epoxy polyester solvent-free paint.

All of our universal radiators are accepted by the British Standards Institution (BSI) and are manufactured and tested in accordance with BS EN 442.


About our universal radiators

Universal radiators are suitable for new installations, extensions of central heating systems or as a replacement for old radiators. The slim profile and refined styling mean that these radiators set new standards in design, performance and class-leading efficiency. These advances also mean that our universal radiators can provide more heat at a faster rate using less water and less energy than traditional radiators.

Key features

  • Pressure tested to 13 bar-maximum operating pressure 10 Bar
  • 10 Year manufacturer’s warranty
  • Made in the UK using British steel-built to BS EN 442 standards- high quality finish using epoxy polyester, solvent free powder paint- Slim profile based on a market leading 25mm pitch.

Calculating your heat requirement

Once you have decided which style you would like for your home, just follow these three simple steps. The following is a guide to help calculate an approximate heat output required for your room. If you require a specific heat output for a given room, we would recommend that you consult your local heating engineer to confirm the exact heat output requirements.

Step 1

Calculate room volume (m3) length x width x height.

Step 2

Calculate required radiator(s) output, as follows:

For BTU (British Thermal Unit): room volume (m3) x 153.

For watts: multiply BTU by 0.293.

Step 3

Add or subtract correction factors.

For solid floor -10% For two outside wall +15%
For uninsulated cavity walls +10% For three outside walls +40%
For foam filled cavity walls -20% For northern aspects +10%
For upstairs bedrooms -25% For no loft insulation +15%
For double glazing -5% For high ceiling - 3m +20%

Step 4

Select the radiator which best suits the size and estimated heat output for the room.
