Hi All,
I’ve posted this in general plumbing and realised perhaps that isn’t the correct place. I’m new to the forum and can’t figure out how to move my thread so am reposting here, so apologies for that.
I have a 2 year old Grant oil fired boiler situated in the garage which is uninsulated. It has a Honeywell frost stat set to 4deg and pipe stat set to 20deg.
In the cold weather we’re having it’s coming on for about 1 minute every so often as expected to do what it’s supposed to. There’s something I just can’t get my head around though. I’m sat here and the heating has been running, it’s just cut off due to the thermostat in the hall making desired temperature, and then 30 seconds later the frost protection is kicking in (I know it’s the frost protection as it’s s-plan and you can hear the prv whilstling).
I can’t get my head around why it is kicking in, the pipe is obviously hot as the heating has just been running and I’m assuming the pipe stat must be working as it only runs for a minute or so? Has anyone got any ideas why this may be or what may be wrong?
thanks,
Matt
