4 Things to consider when choosing a new radiator

Whether you're planning a room redesign or just replacing an existing radiator, here a few things to consider before you buy.

1. Is your radiator the right size?

To make sure the radiator you choose is the right size to heat your room sufficiently, it’s worth taking  the time to complete a Heat Loss calculator. The Bisque website has a good one and there’s also lots of other technical info on their site worth a read.

2. Pipe Centers

Knowing the dimensions of the pipe centers is very important, you need to check these carefully before drilling any holes in tiles or woodwork.  

Manufacturers should state the pipe centers in their literature, but be aware, there may some discrepancies depending on the installation, e.g. if a supplementary heater has been fitted.  

3. Valves

There are two different valve options:

Manual Valves have no labeled settings, you simply turn the valve head until the radiator is giving out the desired amount of heat. They are most suitable in areas where you need the heating to stay fairly consistent, e.g with towel rails. The manual valves also have a more subtle and discreet appearance.

Thermostatic Valves come with an in built temperature sensor and have a range of temperature settings. Thermostatic valves will maintain the room at the temperature you have selected by automatically adjusting the heat output from the radiator. This means you you can take advantage of any ‘free’ heat in the room from the sun during the day for example or any electrical equipment.

One thing to note if you do go for thermostatic valves is that they should always be installed with the heads pointing upwards or to the side (as with straight or double angled valves). They will not work correctly if they are fitted with the heads pointing down and will need to be replaced.

4. Bathroom electric zoning

One more thing to consider is that the bathroom is divided into zones based on a perceived level of risk. Each zone has specific requirements regarding the installation of electrical equipment in that particular zone.

Bisque have kindly uploaded a data sheet of the zones to their site, it’s worth a look if you haven’t yet decided where to put your new radiator.
