All,
(first post here so pls excuse any poor form etc ...)
I have recently taken over a children's nursery and need to do something to regulate the temperature of the scaldingly hot water that issues from the boiler fitted by the previous owner.
A plumber who recently did my Corgi cert said the boiler was very cheap and nasty (Worcerster 24i RSF) but was actually installed properly and was functioning correctly. He recommended fitting a thermostatic blend valve in the system. Having looked at these online tonight it is clear that this is exactly what I need. I am sufficicently sensible and capable with copper to fit one myself, but I have a few questions before I make a right pig's ear of it ...
High vs low pressure? The nursery has a sealed water system - does this automatically make it high pressure?
How close to the taps should the valves be fitted? As close as possible I imagine?
I was planning to install them inline in the hot water pipes with a tee across from the cold water to feed the blend water - is this the correct (and simplest) way to do it?
Where is the best source for these valves - my local Travis Perkins Plumbing Centre only keeps one flavour of valve and it doesn't look like an inline type to me ...?
TMV2 , TMV3 - what's that all about then?
Any other pitfalls or top-tips I should be aware of?
Many thanks in advance
Yours hopefully
Steve
