Hi Jamie, who did you choose in the end? We also need a glazed roof link and there seems to be little chatter on Buildhub regarding this.

Ohhhhh that is very cool on the Shelly front! And my electrician who did the calcs basically warned me to not add any air con to my existing plans 😆 but it sounds like maybe there are ways around that. EDIT: P.S Appreciate your posts around weather compensation (including to another person today!). Doing a lot of reading now into this approach instead

Thanks! I guess the Shelly would just trigger it off or on, but that is definitely a simple way of doing things if I'm happy with the fan speed and that the heat pump can just do its thing. I think I didn't want to rely on A2A for heating as it 'felt' more inefficient than using fan coils given the ASHP would be running at the same time anyway with UFH/UFC. We are projected by our electrician on our single phase setup to be running close to the limit without it so fan coil has much less electric usage. Probably need to wait til we run the calcs but wanted to start from a (relatively) informed place!

Oh interesting. Yes for UFH I certainly wasn't thinking any smart controls from a reactive sense due to aforementioned time lag, but it is the sort of thing I'd want to play around with for automated scheduling based upon data I gather in Home Assistant. For Fan Coils I am more thinking about individual room toggles and cost efficiency with cooling. E.g. turning up the speed on cooling mode only in rooms where we want them, turn them down at night for noise, etc. Your 0-10v thermostat phrasing sent me to this: https://heatmisershop.co.uk/heatmiser-neostat-hc1-0-10v-smart-fan-coil-thermostat/ which has a hub which I can integrate with Home Assistant it seems, so that might be a winner. That's really interesting that you can just leave it fixed at its lowest setting - I certainly seem to be overcomplicating things than necessary - is that the case for cooling as well or do you only use it for heating in your summer house? Definitely food for thought.

Hey all, In the early stages of our self build and I'm thinking about heating and cooling for upstairs. It seems all the cool kids are doing UFH downstairs and using Fan Coils upstairs hooked up to an ASHP for supplemental heating/cooling which seems promising (e.g. Myson iVector S2). What I have been struggling in my research is any way to make them smart and integrate them with my home automation setup (Home Assistant). How are you controlling the systems to facilitate heating and cooling controls? Cheers Nick

Gonna do exactly that with the one I didn't like! But we are going to build one of them as my wife really does love fire...I'm going to explore if a back boiler stove makes sense as the ASHP and utility room will be directly next to the chimney, would be nice to think the heat can hopefully power the UFH too. Might be a waste of money though, research required clearly!

Appreciate all the thoughts. It certainly isn't an ideal situation but we are happy overall with the exterior of the house and the location and land it sits on are just ideal for us - the main frustration for me is the too many chimneys! The reason they are not allowing changes is down to the experience they had getting the planning permission for the 7 plots. They've just had a minor amendment to the plot countered with a large number of additional conditions placed upon the plot (all landowners to pay x for green space, council legal fees) which could delay by up to 6 months - and were advised by a consultant that changes to one of the 7 plots could require changes to all. We're happy to operate under these conditions due to all the positive elements. I will speak to our architect regarding S73. We are completely fine to put any planning requests in we would like after the rest of the plots are built! This is the only house on the plot with two rather than one chimneys, typically...

Yes I agree! We wouldn't have chosen to put them on but unfortunately from a planning perspective we just can't change anything externally if we want this plot. And if they are there it kind of bothers me that we couldn't utilise them at all - the plan was for a single wood pellet burner as a secondary heat source - rest of house will be under floor heating powered by ASHP. Is there any advice on how to build them to lose as little heat as possible? I had a little Google and struggled.

Ah great thanks, that would save a bit of money but didn't think about a replica. Appreciate it!

Hi there, First time poster! We have had an offer accepted for a piece of land - hurrah! Our land is part of a wider plot of 7 properties all with detailed planning permission, and the landowner is building one of the plots themselves to live in. All houses are to be built in a common style and the landowner does not want any changes to the exterior of the house if it requires planning amendments (including material). This is because the council were quite challenging and very particular about various planning elements, but more importantly, are affected by the Natural England nutrient neutrality advice. We are fine with the outside of the house, and the plot is in the perfect location, but the internal layout doesn't fit us 'out of the box' so we are going to be speaking with an architect to make tweaks to it. Something I wanted to check is whether you can remove a chimney breast without informing the planning authorities? This is the only plot with plans for two chimney breasts, the rest all have one, and with potential internal changes it really doesn't make sense for us to have them both. Can we simply not build one without informing, or would it be considered as a non-material or material amendment? Thanks!
