3 steps to get more heat out of your radiators without spending £££

If radiators are left unloved for a number of years, then they can sometimes lose some of their heating power. If you want to reinvigorate your radiators and get some more heat out of them, without having to spend too much money, then we’d recommend the following steps.

1. Radiator Brush

Over time dust, dirt and cobwebs etc can build up in your radiators, this slows down the airflow through the radiator and reduces its efficiency. Radiator brushes can be bought for less than a tenner online to make it easier to brush out all this dust.


You may need to remove the radiator grilles and it is probably a good idea to keep a vacuum cleaner handy as it will create a bit of a dust cloud if your radiators haven’t been cleaned in a while.


2. Reflector Foil

Placing a reflective foil behind your radiator will help make sure that you are not losing too much radiated heat to the wall behind your radiator (although only 20% of a radiator’s heat is radiated… the majority 80% is convected, they should really be called convectionators)

Radiator reflector foils can be bought very cheaply from DIY stores or online, however, tinfoil can also work although it will oxidise over time and lose some of its effectiveness.


3. Bleed Your Radiators

Over time, air can become trapped inside your radiators. This means that the radiator doesn’t heat you or the room as well as it should.


At the top of each radiator will be a square bolt where you attach the radiator key and carefully release the screw thread. It’s best at this point to cover your hand and the key with an old towel or cloth to avoid water from the system squirting out. Unscrew the bolt slowly and carefully as often the water in the central heating system will be pretty dirty so you want to make sure you can soak it up as it comes out.


If the radiator is full of air you will hear a hissing sound as the air is released until eventually water starts dribbling out, this is when the radiator has been fully bled and you can tighten up the screw again.


If you have done the above and would still like a bit more warmth, then consider investing in a SpeedComfort :)
