Central Heating

Pipe Frost Stats Temp advice please

Anonymous user 28/02/2024 - 3.25 PM

Hello I have a L641B1004 pipe Frost Stats and it was set at 25c in conjunction with a wall frost stat set at 5c. But its been going on/off every night a few times keeping me awake ( I now it has been cold these past few nights). It is for a Glow-worm flexicom 15k which is in the Garage. Is it ok to turn the pipe stat down to 10c. I take it that is still a safe temperature for the winter and prevent frozen pipes? I usually have the heating on for 1 hour in the morning and 3 hours on a night sorry to be very dim (I have just moved into the house and this is one of many things that are bugging me) - but why do Honeywell say it should be 25c? it seems a very high temp to have it at Thanks in advance

Are you a tradesperson and able to answer this question?

I'll try to explain, as follows: A frost stat is fitted in order to protect the heating and or boiler if located in a location that may suffer from frost damage e.g. Garage The frost stat should be set to 5 degrees, then a pipe stat ( L641B1004) is wired in series to the frost stat and normally set to 25 degrees this in turn all converges at the heating control wiring junction box for which the boiler is and other heating controls are also wired to. When the internal temperature drops to 5 degrees this triggers the boiler, but when the temperature hits 25 degrees the pipe stat connected to the heating return pipe/circuit of your boiler then turns the boiler OFF, if there were no pipe stat fitted your boiler would continually be running if the temperature of 5 degrees and below continued. So the purpose of the pipe stat is to save on your fuel bills and maintain a level of heat to prevent frost damage to the boiler and heating system. I Hope I have explained matters that you now can relate to?
