I'm in the middle of installing a new heating system in our house.
The setup is 4 port manifold upstairs feeding the 4 upstairs rads, all controlled with heatmiser neostats.
Downstairs is another 4 port mixer manifold feeding 4 UFH zones, again controlled with heatmiser neostats.
The flow/return is 22mm to the downstairs manifold, with the upstairs flow/return being teed off this.
The UFH supplier has told me that zone valves will be required so that these two circuits can operate independently. I cannot see how that these are necessary. In my mind the boiler won't fire until a stat calls for heat, and each circuit is independent due to the actuators on the manifolds.
Of course if it was a more traditional setup with the rads not running off a manifold, I can totally see them being required.
If they are required, of course, I'll put them in, just trying to save spending £100 odd if not really needed!
Any thoughts on this is more than welcome!
Thanks
Lee
