Self Bleed Radiator Valves

This depends on the size of your home and the level of problem you are getting but for most 3 bedroom homes you will need two valves one upstairs and one downstairs, preferable the first valve is fitted to the radiator that feeds off of the boiler. If you have a problem radiator then we would suggest fitting a valve to this particular one as well. If you have a larger sized property or have a lot of problems with air entering the system then we would recommend more. some of our customers have them fitted to every radiator in their homes but this is normally not necessary. If you are unsure then we would recommend you start with two and judge it from there. Installation is quite easy where the old bleeding valve it need take it off and put the new self bleed radiator valve. But always requires a competent person and to know what is he doing.

easy to do,strip out air cock plug,fit auto air cock on to rad,but why ?, if you are having to bleed them all the time, then there is something wrong with your system, ie lots of sludge in system, if an older vented system pump may be pumping over into f and e tank, get a heating engineer to look at it.

If you are considering re-piping the full CH system and i will make the assumption the system will also be flushed and treated whilst carrying this out then there should be no need whatsoever to install automatic bleed valves. If the water in the system is constantly airating or airlocking then there is a fault in the system install or it is dirty.

If it is a combi boiler, the system should not need bleeding regularly. If it does, there is a leak. Find that.
