Hi,

I am trying to find a replacement Thermostatic Blend Valve for my
Thermal Store system. The problem is my valve typically seems to be
oriented the wrong way.

Most of the valves available are as follows:

HOT ------ ------ COLD
|
|
|
MIX

Mine is:-

MIX ----- -----HOT
|
|
|
COLD

Sorry for the bad ASCII drawings, I hope its understandable!

Any idea where I can source such a seemingly none standard valve I
believe its 22mm (as opposed to 15mm) but I am not 100%.

Cheers for any advice. As you can imagine, if I have to fit the
standard valve I will have a plumping nightmare with the pipes.

Who is the thermal store made by? Don't they have a source for it (or is
it horrendously expensive?)

and Gledhill's http://www.gasapplianceguide.co.uk/thermal_store.htm
seem to have the arrangement you're after.

Thanks for replying John.

Unfortunately, I am not sure how I go about identifying the store, its
about 10-12 years old and the store itself is fully lagged with foam.
There doesn't seem to be any distinguishing marks or way to find out
whom exactly it's manufactured by?

It seems those are similar, the first one more so but neither look
much like my store being much more modern affairs I guess.

I will try taking a photograph of it today and maybe taking it to some
local plumbing stores to see if I can get any joy.

The valve itself seems to be manufactured in Germany (or at least for
both English and German markets as it has Kalt / Cold etc).

I did find 15mm Reliance Water Controls one which was L-patterned
although it seemed to be reversed to mine, I definitely need 22mm.

Shall I try contacting some thermal store manufacturers? I can imagine
them being horrendously expensive though

Cheers,

Mike

I meant that the mixing valves look like the same configuration as
yours

You could just ask what make they use and see if you can find them cheaper.

Yeh, mine on further inspection looks a little different, here are
loads of almost identical pics

I realised it had tap connectors, with a fibre washer (you can see I
have repaired the mix outlet in the past, when I bought the house it
was leaking and has the remains of the stuff I didnt scrub off).

The ones I have seen to buy look all pretty much like compression
affairs.

Hmmmm..
