So a week or so in and everything is going well.

I've installed a non return valve as I wanted to stop the siphon. However it rattles like a bag of spanners when the grundfos is in eco mode. I guess because the pump is constantly seeing what pressure there is and adjusts its output accordingly. I've there for just put it on its lowest setting and the rattles have gone. According to the blurb that's running at 28 watts so not so bad.

In full sun I'm maintaining a delta of 10. With cloudy skies I've a delta of around 5. This is less than with the closed solar coil and the heat up of the tank overall is slower.

I'm nervous over the freezing issue so have now added some substantial insulation on the pipes. Yet I still think it will be a worrisome first winter.

I have a considerably clearer airing cupboard now and better access to the pump.

So, so far so good.
