@julianc, that's brilliant. Big day ahead. Hope it all goes according to plan.

Thanks Mars. I was joking with Ecobubl, they leave all the doors open, so the home is cold. And you are just grateful for any heat when they switch the ASHP on 😊

Mixergy slimline 180L hot water tank installed. But not fully connected. There is an external heat exchange (not shown) for the ASHP. Can also integrate the solar PV. Still requires internet connection. And pipe insulation.

External Daikin Altherma 3H HT installed. But still to be commissioned
Looks good eh? This is an 18kW unit. Single fan

@julianc, that is very snazzy. Love the design. Can we get a size pic too when you get a chance?

Daikin Altherma 3H HT is 990mm high by 1270mm wide by 460mm deep or 0.578m3. Below the planning regs 0.6m3 limit. It is also one of the quietest ASHPs on the market with a sound pressure of 38 dBA at 3m. And uses R32 refrigerant - which is better for the environment. I have water only in the circuit between the external unit, internal unit and 27L buffer tank.

And the fan behind the black grill
Quite cool actually

Detail of the internals
We are all wired up. But the Daikin is not recognising the Mixergy tank at the moment. More work to do. And tidying up

Ok, so 95% of work completed
Outdoor unit all working
Indoor unit in the garage (above)
Buffer tank and pump for around the radiators
And finally the Mixergy tank in the airing cupboard Note the insulated heat exchanger at the bottom and the control module at the top Whilst the tank is heating, at the moment it is not from solar PV or the ASHP Mixergy sent the wrong component for the Daikin So my engineer will be back Wednesday to fix Can still schedule and control Mixergy thru the app
So now we just need to learn how to use it Interestingly, the recommendation is to treat it like a boiler and schedule it to come on, rather than on all the time
Time will tell Happy to answer any questions

@julianc, it all looks terrific. Hopefully we'll have a few coolish evenings to see how your system copes, and which will help set a baseline for performance. How exciting.
