Nic Posted October 10 Share Posted October 10 Hi any recommendation for a design service near Exeter for a new build based on a passive design. Two bed timber frame high insulation, airtight . Ground floor UFH and ashp, MVHR and solar to work together is the plan Link to comment Share on other sites More sharing options...
JohnMo Posted October 10 Share Posted October 10 Do it yourself. The only way you will get a sensible outcome. Start with heat loss calculation, use the Jeremy Harris one in boffins corner. That will let you size the heat pump. Either download a trial version of LoopCad, design your floor loops, 150 to 200mm centres should be ok. I used Outsourced Energy for all my UFH parts, they do a design and install service, they should be near you. They supply all good kit. Ventilation treat as separate entity, it will just run in the background. If solar is available it will use it automatically from the consumer unit - nothing complicated needed. Same for the heat pump. 1 Link to comment Share on other sites More sharing options...

SteamyTea Posted October 10 Share Posted October 10 As @JohnMo says. The technical side is really very easy, just working out areas, volumes and multiplying by some constants. You will learn so much about your house and why things are done in a certain way. That knowledge will really pay dividends for decades. 1 1 Link to comment Share on other sites More sharing options...

Easy for some. But well worth it if it is in the skillset. It also demonstrates that some elements are very much more important than others, and some pragmatism...if that is within the skillset. 1 hour ago, Nic said: if someone can do it I’d appreciate it ( can pay 😁) Some who charge for it don't understand it properly either. They maybe think they do., maybe don't care. 1 Link to comment Share on other sites More sharing options...

I used to offer a maths class when working on schools. How much concrete to order for the floor slab X x Y x Z. That took an hour and it was quite a struggle for most. I had planned for this then 2 more questions but dropped them. Even those who could grasp the numbers had trouble with decimal points. A site foreman wanted to learn management. Lesson one......he could not work out the volume of a pit. He could do darts countdowns and horse odds though. It was a matter of needing to know for him. Don't assume it is easy for everyone. 2 Link to comment Share on other sites More sharing options...
