Technical Radiator Questions & Advice

Are the radiators sold by The Radiator Centre suitable for most central heating systems?

In a word, yes! All our radiators are compatible with normal central heating systems and have British Standard fittings. This means you can replace single radiators on your existing system as and when you need or want to.

Can your radiators be used with a combination boiler?

Yes. Our radiators are compatible with any kind of combination central heating boiler.

What sort of radiators would be suitable for a secondary return hot water system?

The same water you use in your taps is used in a secondary hot water circuit. The water must, therefore, be clean and kept free of chemicals. We, therefore, recommend you use radiators made from stainless steel, brass or copper, which limits your choice, but you will still have plenty of styles to choose from. Please contact us to discuss your options if you have a secondary return hot water system.

Can your radiators be used with microbore pipework?

Yes, although they will need to be fitted with adapters. In instances where microbore pipes are fitted throughout your central heating system, any radiators at the end of a long run will take longer to warm up. You can resolve this by fitting wider pipes for the long runs.

Can I replace just one radiator on my system or do I need to change them all?

You can replace as many or as few radiators as you need to.

Are the narrow, space-saving narrow vertical radiators as efficient as other models?

If you have a central heating expansion tank, you need to make sure that the top of the radiator(s) is at least one metre below the tank so that the efficiency of the radiator isn’t impaired.

Can I mix radiators made from different metals on the same system?

Yes. On a standard central heating system, you must use corrosion inhibitors regardless of what metals the radiators are made of: in fact, failure to do so will invalidate the manufacturer’s guarantee. If you have a secondary hot water system, you cannot use corrosion inhibitors; therefore the metals you can use will be restricted, but as long as the radiators you choose are suitable for your system, you can mix and match as much as you like.

Ultimately, your boiler and central heating system will contain mixed materials throughout so using radiators made from different materials to one another won’t be a problem.

I want to install aluminium radiators. Is there anything specifically I need to know?

The main thing you need to bear in mind is to use a corrosion inhibitor that is suitable for aluminium radiators or ‘mixed metals’ - not every inhibitor is suitable so read the label carefully.  

How do I dry towels when the central heating is turned off in the summer?

We offer a large range of towel radiators that have an optional electric heating element. In the colder months, they will warm up when the central heating is on; in the summer months, simply switch to electricity. This is an excellent option to consider if you don’t wish to turn on your central heating in the summer.
