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. 🤣

agree with @MikeGrahamT21 and sounds like your builder doesn't actually know the difference or what MVHR is for! if the house doesn't need MVHR then the airtightness isn't good enough and if the airtightness is good enough then MVHR isn't a choice it's a requirement! so sounds like your builder isn't aiming for a airtightness score of below 3ACH which i believe is the max for mechanical ventilation requirement. so, really your choice is an airtight house or not. if you want AC and don't want MVHR then you need to design for a poor airtightness build. if you want airtight then you need MVHR and then the decision is whether you want to spend on AC. in my opinion, you want both! it's not easy, in my opinion, to retrofit AC without a lot of hassle or having pipes up the side of the buildings from the unit. when it's an empty shell you can run them and cover them up.

It’s been a few years since I bought anything from them but I don’t remember an issue with the in-browser translations even at payment screen. I think remember that the website language set to English was poor but it was quite a while ago and my memory is shit.

Do you really need it flush? Can’t you leave a 5mm gap and just silicone it with a similar colour? that’s what I’m planning to do

Pro Clima are the manufacturer. Tescon Vana is the product. there's other's in the line that deal with different things, like around windows we used the Tescon Profil. if you do a quick search on here you'll find a wealth of information!

+1 to this! It was a revelation when I was told about it.

Tescon Vana tape bought from LATZEL Dämmstoffe. Was about €20 a roll when I last bought.

Did all the window and door taping myself. Norrsken didn’t offer it from what I recall. it’s not too bad once you get the hang of it.

Norrsken customer support has been excellent for us. Did you speak to them?

No idea on this one, sorry. I didn’t get involved in that and left it to the professionals

i keep harking on like a stuck record but we have loads of glass all over and suffer from overheating but we get to look out at the garden and surrounding trees and the sun and sky and stuff. i'd hate to block all that off so we just turn on the AC and enjoy our house without the fear of sweating buckets. 🤣

be aware that east/west windows can also contribute to major solar gain!

What a faff! Just install AC and enjoy the cool house. 😉

shame. yeah. we've never used our AC for heating our units are in the loft space. they are large though so you do need space! servicing them the guys just go up to the loft and work there. we did visit a house where they had them in the ceiling so had to have a large access panel which aesthetically might not please some. we have one unit attached to the joists so is silent as anything. the other above our WIW (which is open to our bedroom) was sat on the joists and vibrated a bit so i got them to sit the unit on some rubber which has reduced the vibrations to barely audible. honestly, barely audible. we have it on 24/7 in the summer and i've never once thought about any noise from it. not used it for heat so can't comment on that sorry.

if it's upstairs then seriously get them to consider a ducted system @Nickfromwales! can run everything in the loft, it's nearly silent and very efficient. none of the breeze when trying to cool a room that comes from a wall unit

a ducted system gets rid of the "breeze"

i have the electric ufh in the bathroom set to 28°C in the morning and evening (the main times we use the bathroom) and can definitely feel the warmth! it's so nice to step on to.

But I like a nicer warmed tiled floor. Feels good underfoot. So it may not be “needed” but it’s certainly wanted!
