Radiator Covers Measuring Guides

How to measure a radiator for a radiator cover or cabinet.

There are three main measurements required to use our radiator cover builder: width, height and depth (as illustrated below), the other measurements needed are for the skirting board and the thermostat access if these are needed.

The illustration below shows the three min sizes you need form your radiator to enter into the radiator cover builder, the width measurement of your radiator from the outer edge of the valve on the left to the outer edge on the right side, then the height from the floor to the top of the radiator and finally the depth from the wall to the front or the furthest point forwards from the wall.

The radiator cover’s internal dimension will be larger than the valve to valve measurement to allow the radiator cover to fit over the valves with an adequate air gap this is illustrated below.

Design Tip – If your radiator is poorly positioned, you can always order a greater width than you actually need in order to bring symmetry and balance to your room, or even if you have a low radiator order a larger height to make a usable shelf for ornamental or photo display area.

Actual Radiator Dimensions.

The measurements you input to the Radiator Cover Builder are your actual radiator sizes (as illustrated above) there is a small box below which shows you the internal size of the radiator cover, this is your actual size plus an air space.

When measuring your radiator the dimensions are always better slightly larger than smaller.

Internal Radiator Cover Dimensions.

The illustration below shows the radiator cover carcass outline in blue, as you can see there is spare area all the way around the radiator to allow air flow.

When you enter your measurements in to our Radiator Cover Builder we automatically add on an additional 40mm (4cm) on the width, an additional 30mm (3cm) on the height measurement to allow air flow or heat to rise from the radiator in to the room as normal and an additional  minimum of 20mm (2cm) on the depth also for air flow and to allow for the depth of the front grille panel (3-4mm) and the Bancroft grille is 9mm thick.

Finished Radiator Cover Dimensions.

The finished external sizes will obviously be larger than the internal dimensions due to the thickness of our materials used, 18mm premium MDF and also the front and side overhangs on the top shelf.

From your actual radiator sizes these are the approximate measurements to arrive at the finished external sizes 

  1. Extra 120mm (12cm) on the internal width/length, this will be top shelf length
  2. Extra 50mm (5cm) on the height
  3. Extra 65mm (6.5cm) on the radiator depth, this will be the top shelf depth.

(Please check that the External sizes can be accommodated where the cover is to be located)

Skirting Board

Our skirting board cut out has a straight vertical cut and is rounded at the top corner (as per illustration below) or if you require we can square cut this please let us know in the additional notes & instructions box, We do not advise ourselves trying to profile cut these cutouts from templates etc as in reality most walls floors etc etc are never straight, true or level and this may cause more problems, if you wish to profile cut yourself on site this will be a more accurate way.

Thermostat Access

The thermostat controllers are not on all radiators and more often than not are very rarely used! depending on the size of the radiator cover they are easily lifted from the internal brackets to gain access for cleaning or occasional ‘bleeding’ or thermostat adjustment, however if you do require more frequent access to the thermo adjuster then you will need some kind of access:

When measuring up for a thermostat hatch we will require the height from the floor to the top of the thermo valve (as per picture below), we may also need the depth if the valve is deeper than the radiator, we will also need to know which side the valve is situated on ‘left or right’ as you look at the radiator, we then allow a cut out or hatch as explained below. We can also put the access hatch in the front panel if the radiator valve is in a corner, please let us know if you need this.

We normally make our thermostat access openings around 100mm from top to bottom and the depth the same as the depth of the radiator measurement however if you require a deeper cut or a higher cut to allow better access then please let us know by entering in the ‘additional notes & instructions’ box in the made to measure cover builder page on the right.
