    I had a new boiler installed 3 years ago. Recently, I called in a plumber to fix leaking radiator valves. He drained the system and repaired the leaking valves. He also fitted 2 TRVs on 2 radiators in my lounge where there hadn't been TRVs before. I have a large lounge (originally 2 rooms) with 3 radiators and now they all have TRVs. I turned on the heating and most of the radiators in the house are making a continuous gushing, flowing sound which is intolerably loud. There is also a gushing sound in the pipes, particularly the vertical pipes bringing water from upstairs.

    I've bled the radiators 3 times. Initially, there was air in 2 upstairs radiators. The water pressure on the boiler reads 1 1/2 to 2 bars. Turning off a radiator by turning down the TRV stops the noise, but I need all 3 radiators on in my lounge. I've turned off the heating this evening because I can't tolerate the noise. I didn't have this problem before the leaks were repaired. Please can someone advise me what to do.

    Hi. Thank you. My room stat is in the lounge. I don't know what an open vented system is! I suspect (not knowing much about central heating systems) that the noise is connected to the new TRVs as it's too much of a coincidence that the problem started when these were installed.

    Thank you. Sorry, I don't know what the f+e is, but it seems I'm going to have to get the plumber back and suggesting these possible causes will be helpful - so thanks for that.

    I just Googled open vented system and no I don't think I have that. I have a Worcester Greenstar combi boiler. Hope that makes sense.

    What is the pump speed setting? If it's high, You could try reducing it (if that's an option with a combi).

    Thanks very much for all your help, everyone. I've phoned the plumber and left a message! Hope he can cure the problem as having the heating on is not an option - I can't bear the noise.

    Thank you ver much. I don't know how to locate the pump speed setting, but I've left a message for the plumber to come back and fix the problem.

    On a separate pump it's straightforward, there's a manual selector on the pump. Don't know if it's the same on a combi, or if done via the software settings (if it's possible at all). Maybe one of the experts will tell us.

    Where is the thermostat in the lounge in relation to the radiators. The rads may not have had trvs for the reason that your stat is in there.
