Air in 1 radiator

[nicko]

aargh I have recently installed my own central heating, had the boiler setup and tested by a corgi guy and all was well ! now I find the upstairs rad nearest to the boiler keeps getting air (I think its air) in it. we are talking about 5 - 10 seconds worth of air per day when released. I tried looking for a leak but found none, suspect it could be from the boiler itself somehow, it is a biasi condensing boiler,still under warrant, is there anbody who could give me any help on this please, I am not a plumber by trade.. also will putting leak sealer in do any damage to pump auto air vent or any other items ?

many thanks,

NIck

The Corgi guy who set it up and tested it?

It is just possible that it is residual air left in the system (probably due to a poorly designed system - particularly main delivery pipework 22mm stoof) Other than that the whole system needs checking over by someone competant - good luck findin one a them!!

If it's a brand new system it could be air that was in the water coming out when it's heated and settling in the near point to the heat source. In which case it will eventually all come out. Perhaps a month? If that's not it, perhaps air is entering at the low pessure point, being the flange on the 'in' side or the pump. so make sure it's tightened properly.

Buy a good book on central heating. Try reading the boiler manual it might give you a clue to what you have done wrong. Warranty for boiler probably void now if not fitted to manufactures instructions.

Many thanks for all your suggestions, i will look through manual again and double check for leaks, but can anyone tell if leak sealers that are put into the system are ok or should I stay away from them ?

thanks again,

NIck

Have heard a few bad rumours only - I haven't actually had or seen any problems with them. Really doubt that's your problem though.

thanks for that chris, much appreciated. i did have another thought, if i am able to let air out of this radiator twice a day for about 3 - 4 secondseach time, would a leak allowing this much air in/water out be fairly obvious by a pool of escaping water ? i just occured to me that I have a dead endn run where I have run 2 pipes for a future radiator that are both capped off, could it be air trapped in this pipe slowly getting pushed out ?
