[Sticky] Air source heat pump roll call – what heat pump brand and model do you have?

Mars · 2021-12-01T09:12:52Z

With more and more members joining the forums, I tend to lose track and forget users’ ASHP brands and sizes. This post is intended to act as a quick reference and to engage with other users that have similar units. It’ll have forums members username, ASHP model and size, and we will structure it by brand. Please post your details as a reply. I’ll copy the details into the post and delete the reply.

@darrell-p There's another new Forum Member, @wully who also has a Thermino, together with a ZEB(!)

He started a Topic on Heat Batteries here, which you might like to read.

@ecoste, @walnut-tree-cottage these are both great pieces of kit.

As I am sure you know running a heat pump is rather different to running a boiler. Whereas with boilers we tend to have TRVs switching radiators on and off, and thermostats switching the boiler on/off, with heat pumps its generally best, both for cost and comfort, to leave radiators and the pump itself on all the time just ticking away at a low temperature.

If you havent already can I suggest you read this introductory article which should help you understand how to get the best out of it. Please feel free to start a thread and post questions if you are unsure.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
