Kitchen cupboards have been in place a good 10 years with the walls repainted with a mat emulsion a couple of times over the years. I am noticing what looks like a damp wall next to the cupboard but the wall is a stud internal wall with no pipes or radiators on either side of the wall. The...

The question is based around does the gas, the compressor or both contribute to the demisting of the windscreen? I don’t want to pay for regassing if the compressor, which is covered by an exstended warranty is faulty. As part of a compressor repair the gas would then be covered by the warranty.

I have the car booked in for the air conditioning to be regassed, as the car is no longer cooling but would this also affect the lack of demisting of the windscreen today in the rain? I was wondering if demisting is solely the function of the AC compressor so maybe that has failed?

If you are renting a flat isn’t this the responsibility of the landlord?

No never, all pipework runs up from the ground floor and down from the first floor so I assume it is located between floors.

I live in a 1990 built dob and dab 4 bedroom smallish detached house with a 32kW Ideal Vogue fitted in August 2022. The CH temp is set for 50C to boost boiler efficiency and runs through 10mm microbore pipework downstairs with standard pipework upstarted. Rather than using weather compensation...

Shouldn’t the installer be tasked with getting it to work properly. Was it their first install?

Do you actually need a higher temperature than 40C. Anything above and you are likely to add cold water from the tap.

TRV’s can unbalance a system according to some heating experts

Watch a selection of YouTube videos on balancing. I followed the advice and got mine heating up simultaneously.

If it isn’t broken why fix it?

Thanks for the expansions but I thought the whole point of adding inhibitor was to prevent the corrosion. My system is fully dossed with X100 and has been tested for its strength.

So water within the CH is replaced by a certain amount of air indefinitely of equal pressure? My understanding is that if fresh water is introduced then air from that water will separate into the tops of radiator or towel rails. So I don’t have an issue then?

We had a combi boiler that has now been replaced by a combi new boiler last year. Both have the same symptoms. The old boiler was set to 1 bar pressure. This new one sits at 1.5 when the CH water is cold. Both maintain pressure until I bleed a towel rail then the pressure drops. Both systems...

Thanks for the answers. All the gaskets were changed from white to black around 6 or 7 years ago. I will try the spoon method later today and if that does not work will try pushing the gasket more into the corners by pulling back a length
