Yes. I have to say a brilliant piece of kit 🙂

Will they work with heat pumps and thermal solar?

Yes if you get the right version. They can have an internal piped heating coil (as well as an electric element). Mine has that, not used yet, but also a built in solar diverter so you just need a cable to your meter cupboard to detect solar panel export and off you go 🙂

Much appreciated Will nudge our installer, have had thermal solar pre-feed to combi gas boiler for past 15 years (brilliantly simple!l) but probably need a different tank when doing heat pump next year, so this might be a solution. Ta.

We were also thinking a heat-pump in a couple of years so this was a nice first step. It's in the attic. Plumbing took a day. Left combi in place pipe wise so we can, if needed switch back just with two valves. Electrics a couple of hours. App for control, plus a manual 'gauge' in the bathroom 👍 🤔

Terrific
