Yes see that is set to 5 degrees. So,frost stat turns it on and pipe turns it off? Tweaking the pipe stat down slightly seemed to turn heating off perhaps it is set to too high a min whilst frost stat at 5 degree is sensible min? Ed

How do you set the frost stat as looks like a plain sealed box? Ed

There is Honeywell frost stat which is size of a light switch plus a pipe stat as well. Pipe stat has dial on it which goes from 0 to 40. Never touched it before but tweaking it down from the 20 it was on to about 15 the boiler went off ( as i write this). Given boiler is towards front of...

Now confused, something controlling boiler but not sure what. Like your recommendation I thought constant best plan. Reduced overnight temp to get boiler to cut off. Middlem of night and heating on and display on stat reads 19 so boiler should be off. Put programmer to be off overnight...

Thanks for coming back. I guess I had assumed the house wouldn't drop below that level but maybe it is. I'll test the 5 degree idea and see what happens. It is a 1950's solid brick detached house. Double glazed (oldish units) but has got reasonable loft insulation as have increased that...

I thought it should be on constant but turned it off as CH was coming on at night. The stat is programmed on a 5+2 day schedule. 5 days/week - 5:40 - 9 am - 20 deg 9 am to 12 noon - 18 deg 12-2pm - 20 deg 2 - 4pm - 18 deg 4 pm - 10 - 20 deg 10pm to 5:40 - 12.5 deg Stat is in...

I have a Honeywell 7 day programmer (controls water and heating independently) and has 3 on off periods. The installer installed this with a Drayton wireless room stat. It was suggested to me that I upgrade this to a programmable stat so I have a Drayton 7 day programmable thermostat now...

Thanks as I did think 200 was a bit cheap as I think the quote from one company for a gas liner was close on 1000. It is a brick flue external wall ( stands proud of the house). What does MI mean - being a bit thick today Ed

We have a 1950's brick chimney and an inset gas fire which we have removed (local gas safe man). I am now going to open out the builders opening to install a gas stove in the fireplace. Our chimney is unlined but appears to draw fine from the smoke test the gas safe guy did. Do I need...

I hope this isn't a repetition of previous questions.......... We are having building work done and sorting out/upgrading our heating in the process. We are moving to an unvented cylinder and system boiler. We had 3 plumbers quote who all quoted similar prices. 3 plumbers = 3 boilers...
