Needed- Low temperature blending valve 20-45c

[gravelrash]

I need a low temp blending valve 20-45c for UFH...flow temp calculated at 27c at outside temp of -5.  Anyone know of a supplier?

A normal one should go down to 27.

 

The other way to do it is set your flow temp at the boiler and just use the blending valve as a safety device.  That works as long as you don't have radiators at a different temperature.

Any use?

and it'll happily run at very low temps. Dunno if they supply to the UK any more tho?

Same functionality as the Ivar. I have seen these for sale, eBay iirc.
