I think my one is Kaput. We added a radiator a bit far out and it never warmed up. But I also noticed that the boiler would go on and off regularly even when the radiator return pipe was still cold. But the flow from the ABP was always hot and the boiler sensing the hot water coming in would then shut off even thought the demand was still there for heat.
I tried to adjust the valve and had no idea how to make it change - same issue as described above - but I wasn't smart enough to see that it did change slowly after several turns. I went to city plumbing and they showed me another and we figured out how it worked and theirs was the same as mine. So back home I tried to shut it off but it just turns and turns. I turned at least 20-30 turns in either direction and never a hard stop so I think it is just rotating inside and is non functional so have to replace it. But I have 2 questions:
1. It is located only 2-3 feet from the boiler. There are branches off to the bathroom radiators immediately after so it is the furtherst point from the boiler before a split. I know it needs to be before any branching but is this far enough?
2. Honeywell have one - I think the original is Honeywell - but its GBP50-60. There are similar looking ones - one is Corgi and others in Toolstation or Screwfix for a lot less. They are a paid to fit as no shutoff valves so will drain the boiler in the process. Should I go for the Honeywell or are the cheaper - identical looking ones really the same. Don't want to save on the valve and find it breaks in a few years. But if the original was Honeywell , its not been touched since it was fitted and is only 7 years old!!
3. If it is short circuiting - either because it is broken or set too low, then cranking it up a couple of 0.1 bars should then let the boiler shunt water further and faster around the circuit?
Any feedback from a knowledgeable person would really be appreciated. WFH now and study always freezing!!
