Very hot bathroom wall

[Sharpenter]

Hi there,

I've just moved into my first home (3 bed Vic mid-terrace) which has been recently refurbished, incl. the plumbing.

We've noticed though that one of the bathroom walls is very hot in a line from the floor to mid-wall. When I say hot I mean 60+ degrees celsius as measured with a laser 'gun'. I suspect that this is beacuse of the pipe feeding the rad in the bed above the bathroom.

Basically, I want to know whether I need to be concerned about this? The paint is peeling from the heat which I can live with, but is it potentially a bigger problem?

Cheers and thanks,

Sharpenter

If its that hot on the wall, heating flow temperature is way too high.

Turn the boiler temperature down. If its a new boiler, then it will be a condensing type. The lower the temperature, the happier it will be. Start off at about 65C and see if you can still heat the house to a comfortable temperature.

I guess its probably 75C plus at the moment.

Done, and it's done the trick. Nice one keithsb!

It is indeed a condensing boiler and for some reason both the temp dials were at max. Both about halfway now and the house is plenty warm enough.

I am pleased that you have it sorted. Reading the posts on this forum, it seems that quite a few people with modern condensing boilers have the flow temperature set very high.

If you have a monitor on the return temperature, and can keep it below 55C, then you stand a good chance of making use of the latent heat released when condensation takes place.

This may not be possible if your radiators cannot provide enough output at lower temperatures. It depends on who designed the system.
