Thanks to all who have offered advice. I have now found a local plumber who will service my existing boiler so I will seek his opinion on its condition and potential serviceable life. From all the comments I’ve received it seems the decision between replacing it (and when) with either another...

I must admit I too have doubts about the need to replace a 16yr old boiler which has been annually serviced and had fresh CH protector added every 2yrs. Apart from a failed expansion vessel it has never let me down and as the last of the non-condensing type it is almost as efficient as the...

Understood. Thanks for advice. As my hot water pressure is OK and Im not planning on a loft conversion anytime soon so I think I’ll stick with my loft tank and vented cylinder and save the additional expense of upgrading to an unvented one. As for the boiler, it seems there is little to gain in...

Yes. I’ve ruled out a combi because we have 4 bedrooms and have more than 1 bathroom. Everything I have read suggests a main advantage of system boilers is you don’t need a cold water tank in the loft -but I still have one hence the question why I need a system boiler - or could I get rid the...

I am considering replacing my existing Vaillant thermocompact (non-condensing) system boiler principally because it is now 16 yr old. It’s currently part of an indirect, unvented, Y plan set- up comprising a vented indirect hot water cylinder ( in the airing cupboard) and a cold water tank (...

Thanks “oldbuffer” and “Ianmcd”. The ABV alignment is OK and I’ve bled the valve. No change. Because the noise disappears when I turn up the room thermostat or close the lower gate valve from the cylinder I’m beginning to think it is either (a) a faulty gate valve (b) a sticking ball in the...

Is anyone able to provide a response to my earlier post which has gone unanswered since Feb?

Following my earlier text is anyone able to suggest the most likely cause of my CH noise problem or what other tests I can do to narrow down the possible culprit?

OK this is what happens. Programmer set at HW off, CH on, Room thermo not calling for heat and No tension on 3 way valve. When the programmer switches on the HW, the 3 way valve is tensioned and the vibration starts. The vibration can be stopped if I turn up the room thermo and it calls for...

Thanks Meldrewsmate. I’ll try retesting as you suggest and report outcome. I can’t recall the make of the replacement Synchron motor ( I didn’t replace the whole head) but I do have a spare genuine Honeywell 3 way valve (complete unit) if I need to replace it or just the detachable head.

P.s. He also fitted TRVs to all my rads.

My plumber recommended it when he replaced my cylinder a couple of years ago. I wasn’t wholly convinced at the time but I’ve used him for a lot of other work so I trusted his judgement. You will see from the pics that it has isolating gate valves on either side. If I close them to disable the...

Here are some pics from the airing cupboard.

It’s‘ probably a coincidence but ever since I had an auto bypass fitted (which required some pipework alterations in my airing cupboard), I’ve been getting a vibration noise when my programmer instructs my Honeywell 3 way port valve to switch from Heating only to Heating and Hot water. My...

I’m getting intermittent vibration and noise from a newly installed Danfloss auto by-pass valve. This was put in following installation of Dayton TRVs on all my rads. I can isolate the valve and the noise stops but would like to know if removing a TRV head from, say, a bathroom towel rail ( or...
