Does the need to protect central heating radiators even enter your mind?
You must protect central heating radiators, they are an investment that you expect to last for years. OK, so they are not the most interesting things in the world. Unless you have a designer radiator such as the Revive column radiator in a colour, white or raw metal. But they are pretty much essential to heat your room. The problem is that most are neglected and shoved in behind settees or curtains. Radiators need TLC and a little bit of love and attention every now and then just like the central heating system itself. Then they will love you back by giving you unrequited heat when you need it. the same goes for towel rails in the bathroom. These too will need some occasional maintenance.
The main thing to do when it come to radiator maintenance is just check that there are no leaks and cold spots. The cold spots can be caused by air or sludge. The air accumulates at the top of the radiator and the sludge at the bottom so you will be able to tell which one it is. The air can be vented using the bleed nut normally fitted on the top of the rad. All you need for this is a radiator key which you use to open the bleed valve at the end of the radiator anti-clockwise. Firstly, the air escapes from the valve when it is opened and once this has escaped then water will start to leak out of the radiator. At this point the radiator bleed valve can be shut. Bleeding radiators is a fairly simple task that most people can carry out themselves as a part of the general DIY maintenance you have to do around the home. The sludge build-up on the other hand is going to have to drained out of the radiator and thoroughly cleaned out. You may prefer to get a plumber to do this laborious task.
You should also check your pipework occasionally to ensure that it is in good condition. Water pipes can decay over time, and joints can leak and start to cause problems. Look for the tell-tale copper build up at the seals and joints of pipes. Arrange for a plumber to take a look if you identify a potential problem.
When it comes to the radiator valves you'll find that each radiator has two valves attached to it. the first is a lockshield valve that does not need adjusting once it has been set up correctly. There should be a plastic cap over the lockshield valve which is there to dissuade you from altering the setting. The other valve may either be a manual valve or a thermostatic radiator valve (TRV) which are the valves you can alter to change the heat output of the radiator into the room. Again, you may wish to change the settings on these user-adjustable valves if your room is either too hot or too cold.
Once you have done some visual and touch checks then you need to try and think about how you protect central heating radiators. It needs protecting as it has water inside and a fluctuating temperature. If it is left unchecked then you may find that you have a lot of un-wanted black water all over your carpets or floor. There are various inhibitors and protectors on the market that need to be used in-conjunction with a cleaner.
Adey MC1 Protector & Adey MC3 Cleaner
Like the Adey MC3 Cleaner which chemical cleans the metal and loosens any debris to prepare the system for the Protector. It is pointless just adding more Protector and not dealing with the issue. When it comes to a protector then a comparable product is the Adey MC1 500ml Protector which will make your system not only more efficient but keep it free from sludge, air and corrosion and protect central heating radiators.
Also bear in mind that if you have a 1, 2 or even 5 year warranty on your radiators, this will be reliant on you protecting your central heating radiators with chemicals and cleaning.
