@jamespa it is a good idea, but not easy as you say. We actually have something along these lines scheduled in for recording next week Friday for the podcast.

This article highlights important factors to consider when installing a heat pump. Identifying red flags, such as poor sizing, improper installation, and lack of maintenance plans, ensures you avoid costly mistakes and achieve optimal system performance.

If I had a new ASHP installed I would still have to have a hot water cylinder. I watched the relevant video on this site. But I don't need any buffer unit. 

Can I get clarification on this point. 

Can the ASHP External unit, supply heat for Central Heating radiators or UFH at one temperature and one set of F&R pipes and do that supply directly? Bypassing the cylinder?

Or have I got that completely wrong and need to go away and do some serious reading? 🤔

The ASHP, just like a boiler, can supply water at only one temperature at any time.  So it switches between space heating and DHW.  There will be one set of F&R from the heat pump, which splits into two sets at a diverter valve. 

The reason that boilers (as we set them up in the UK) can do both simultaneously is that they run the heating at a high flow temperature, resulting in both reduced comfort and a 10% increase in energy consumption and therefore cost.  Boilers, like heat pumps, are actually best run at a low temperature with weather compensation (best both for comfort and cost!), but in the UK we rarely do this, unlike some more enlightened countries in mainland Europe.
