Radiator Top Tips

Throughout the winter months, we rely heavily on our heating, therefore it’s important to ensure that our heating systems are in good working order. As we come into winter, it’s important to know how to look after our radiators. The Manufacturers Association of Radiators and Convectors (MARC) have compiled their top tips on how to maintain domestic radiators, as well as maximising their efficiency:

Keep Curtains Out of The Way

It is important to make sure your curtains aren’t tucked behind your radiators, as most modern radiators release half of their heat from behind the front panel. This means tucking your curtains behind the radiator restricts the flow of warm air, or in some cases it completely blocks the flow of warm air.

Thermostatic Radiator Valves

You can independently control heat in every room of your house, if you have a TRV (thermostatic radiator valve) installed.

Removing Trapped Air

Over time, air can become trapped inside radiators. This means they don’t heat up properly, and consequently your room won’t be heated properly. If your room happens to feel colder than usual, your radiator may need bleeding. It is recommended that you do this twice a year.

Drying Your Clothes

You shouldn’t hang your clothes over your radiator, as this reduces the efficiency of your central heating system. If you have to use your heating for drying clothes, buy a small radiator airer. This hang off the front of the radiator and doesn't restrict the flow of warm air.

Keep Clear

Avoid using radiator covers where possible, as TRVs sense the temperature of the air surrounding them, and placing a cover over the radiator encloses the TRV. This means it will think that the room temperature is higher than it actually is. If the TRV doesn’t have the accurate temperature, then your radiator won’t be efficient.


Too many coats of paint reduces the efficiency of the radiator, so it is important to be careful when painting your radiator.

Mixing Radiators

It’s recommended that you stick with the same type of metal if you have to change or add a new radiator, as introducing more than one type of metal radiator in your home can increase the risk of corrosion.

Choose the Right Radiator

We recommend performing a Heat Loss Calculation if you’re buying a new radiator. By inputing information about your home, you’ll be able to ensure that your home will be heated efficiently by working out the required radiator Watt/BTU outputs.

Even though looking after your radiators is important, it is also crucial to make sure that the hub of your heating system (your boiler) is also taken care of. You should make sure your boiler is serviced on a yearly basis. It’s quick and ensures that your home and water will be kept warm throughout the cold winter months.
