Thanks for all this advice. I think that the thermostatic valve may
therefore be to blame. Now if they come in different 'colours'

1 Which is the one I need for a combi boiler?

Reading from my 10 year old installation instructions.... Pink cartridge.

Multipoint systems, mains fed gas fired instantaneous water heaters must
be capable of raising the temperature of the incoming water by 45C and
delivering a flow rate of not less than 7litres/min to the shower valve.

Thanks I'll look into this. I won't rush just look around and see. I suspect
this may be the problem though.

2. Also I assume it's a pretty easy job to do and is a matter of just
undoing a few screws and taking the old one out and putting a new one in.

Er. IANAPlumber but yes. Turning off the water supplies helps:-)

I think I'd worked that out!!!!

3. On a the Aqualisa website there's all sorts of shower thermostatic
valves. How do I decide which one is the right one?

Pass. You could also try Shower Doctor. I don't have a URL.

Had a look at that site. Very helpful.

Thanks to everybody for the info.

Ta,
