Perhaps I'm missing something.
As I said this is not my area but -
My point exactly. I am sure you are brilliant at what you do - but would struggle with heating electrics
As to the pipe stat limiting the CH - there has to be a fail safe on it for kids areas-
You didn't say only the children's area.
I don't see how there can be, anything can fail.
Two pipe stats in series? Radiator cover(s)?
Sorry I just confused things there. Forget the kids play area my original brief was to keep the boiler condensating when servicing the rads. To do this the flow temp must be reduced as low as possible. (as to the fail bit - our stuff fails safe - as in if it fails it needs to be manually reset (like an RCD))
and how does a pipe stat change the flow temp of the boiler?
It doesn't have to if it turns off the CH when it reaches 80°.
he whole essance of my original question is that the DHW cyl needs 80 to comply to its recovery time - but a split second later - the Rads might call for heat and want to run at 65 degrees? All of this is done with (usually 240 in this scenario) external controls
we are a bit further down the road than blending on flow temp with cold water to get other temps - we put a man on the moon 40 years ago? .
Did we?
