Hi Everyone,

Would really appreciate your help here, I have a Logic Heat 18 Boiler which is not a combi boiler.

The boiler makes a lot of gurgling/water running through pipes and radiator type of noise. when I turn the boiler on, the radiators do not get hot until I bleed couple of the radiators then it works perfectly fine. I am having to bleed the radiators every time I turn the boiler on. It takes about a min or so to bleed the radiators until a trickle of water starts splashing out.

I really need help to fix this problem, any support would be highly appreciated.

Thanks

It can be many things, but first I would try is turning down pump speed, I am not a plumber, but did work with water pumps, is there a header tank or an expansion vessel? if latter may be that is faulty? if the expansion vessel is not working every time it heats up water is pushed out, and so when it cools it will suck in air.
