A year after fitting the zone valve my oil consumption was down 4% on 2009 and 9% on 2008. Recovery time is about 1/2 hour.

New tank in with the addition of a two port valve. Hopefully get it all wired up tomorrow. Thanks for the wiring diagram D_Hailsham. I was thinking I would have to use a relay, but that will work just great.

Thanks for all the comments and help. I think I will just add a two port valve for now and change to S plan if and when the boiler gets changed.

Thanks Ted, I'll put a two port in and that will give me individual ( zoned ) control of the hot water, but what do you think about a pump to decrease the reheat time?

The layout would make it tricky. The boiler has 4 tappings and is in the garage, and the rad circuit is via a manifold with a pump on the return. F&E feed is at to tee at bottom of cylinder coil and vent is at tee at the top of the coil. So I was hoping the addition of a motor valve on the feed...

I want to add another pump to pump the hot water from the boiler around the coil in the hot water cylinder to improve efficiency. At the moment the boiler has two circuits, one gravity feed to the hot water cylinder and one pumped (on the return to the radiators). 1. Can I add a pump next to...
