    Balenza You will of course have a bypass on the CH circuit in the form of a lockshielded radiator in the room where the room stat is located. I was talking about the HW circuit. W Plan not quicker than S Plan? Are you sure you know what a W Plan is?

    Just because twgas and I posted the same conclusion within 7 mins does not mean that we are the same person nor even long-lost twins. We are merely inherently and irrevocably right and superior etc ramble. Atag and Viessmann boilers do internal W-Plans. It's the only way. Gleaming.

    Install it on a W-Plan and forget bypasses and throttles. 28mm from the boiler if you so wish. The recovery time on the cylinder will be quicker than any S-Plan.

    ravenheat 820/20

Classic problem on this boiler and for this valve in my experience. The valve I used was one from BES. They...
