I have (very sadly!) almost “run out” of my stock of Rubbol BL Primer (blue label) and Rubbol BL Satura (purple label) both “water based” which I have used for many years and found to be without equal. As they are both now discontinued (could never understand why !) what is currently recommended...

Many thanks for that, so the HW cylinder thermostat 100% over-rides everything ? As per my original post, I suspected the HW cylinder might be involved !

No.

I had a replacement Vaillant ecoTech Plus Open Vent boiler installed in my loft about 9 months together with new pump, 3 way valve, Drayton programmer etc. Since then the system has worked perfectly other than this one query. A couple of weeks ago I noticed that occassionally neither the pump...

The original boiler was wired in identical fashion to the current one viz. "in series" with the pipe stat on the return pipe in the identical position as previously. I am only concerned about "frost protection" in the loft to my bungalow. My bungalow was a "new build" 31 years on an estate of...

The point I am (unsuccessfully !) trying to make is why (in normal operating situation) boilers (in lofts) with well insulated pipework are protected by frost stats whereas (insulated) tanks with well insulted pipework are not. ? I am not taking in any way about the situatuon where a property...

Thanks for that, which makes perfect sense but how about the (well insulated) pipework connected to the CW and F&E tanks in a loft - why are we not generally concerned about these freezing ?

Please forgive my ignorance, but as the pipework around my boiler is well insulated why are a frost and pipe stat actually needed ? Is it for any other reason than just "insurance" ?

Can anyone provide any additional information in reklation to my 3 queries ? Many thanks for the detailed response. appreciated.

The pipework in the loft is now well insulated, better than before. The frost stat are wired in series, does one override the other ?

I had a Vaillant ecoTech Plus Open Vent boiler fitted in my loft about 6 months together with replacement Honeywell Frost (set at 3C) and Pipe (set at 20C) stats. These replaced a 30 year old boiler (Ideal Classic NF40) and identical frost and pipe stats, again in the loft to my bungalow. My...

Thanks.

Cheers !

The pics show the "good hip end" of my bungalow. The hip with defective ridge tiles is the other end and is difficult to photograph. All my roof tiles are fine it is only the 2 lines of sloping ridge tiles to the hip that will require attention albeit not immediately but as I live in a very...

Thanks for the precise reply datarebel. Does the Marley Mendip range include matching ridge tiles ?
