I fail to see how a drawer will fit. It would have to be a shallow drawer to allow the Pro3 to fit behind? And then accessing the unit could be a faff maybe? We just have a wide double door cupboard that has no shelves to give space for all the plumbing and Quooker units. It does all take up quite a lot of space. sadly I don’t have a photo to hand.

We had plenty of space under our sink to install it without cutting holes in the base! And we have the cube installed there as well. Have you got a particularly deep sink or something?

That’s why I use the loctite. Much easier for us amateurs.

Also check the planning permission as I had time limits on the period work was allowed. E.g. up to 12:30pm on a Saturday.

Financial compensation should the time period overrun? Which it will. There is no penalty for overrunning stated currently.

Just remember that everything takes longer than you think so take the builder’s time estimates with a pinch of salt and negotiate for the worst (and then add some extra time on!)

I’ve not read everything in this thread as I’m too lazy, but our back garden is now where the old bungalow used to be and after the demolition it all got filled in and levelled-ish with clay. Was a dried out baked slab of solid ground that pooled water. I rotavated the clay and added 20 tons of manure which got turned in as well. The covered the lot in 100mm-ish of grade B topsoil and seeded the lot. We now have a nice green lawn that wasn’t waterlogged at all this year during the constant rain so I’m happy! the bit to the right of the house will just have some topsoil put on it and then sown with wildflowers eventually.

We were told we needed two units but I pushed back as I didn’t want to pay for two units and to pay to install two units and to maintain 2 units with filter changes etc. So the M&E company calculated that if we upped the duct size to 92mm we could use one Zehnder 600 which is what we did and I have no complaints at all.

Not sure about anyone else but I built our house for us and couldn’t care less about any future buyers!

we have multiple 5A sockets controlled via Loxone for ambient lighting.

If only there was a way to nicely automate this I’d be on it as we currently use the cheap period on Cosy to heat the DHW for evening showers at 1pm (or PV if the sun is shining) using the ASHP.

I didn’t install a solar diverter for our PV as I figured I’d get a better COP from the ASHP than a 1:1 using a diverter. The ASHP is also run from the PV anyway so, in theory, I believe I’m using less PV to get the tank heated.

But can’t cool while the hot water tank is heating, right? I also considered fan coils and floor cooling but it was getting complicated and seemed like a lot of faff. having separate AC and ASHP just kept it simple for me.

I like to look out at the blue sky so have AC to allow that if I wish to! We also have blinds to help with overheating but I don’t want to live in a house in permanent shade during the summer months.

ps. have you considered external blinds on the windows that will have solar gain? our blinds keep those rooms cooler than the rest of the house but we also need AC as we've not got blinds everywhere and we like to actually look out the windows. 🤣
