I'm probably a bit late, I am in the middle of a self build and am looking for advice. I have 240 m2 of floor space and have opted for UFH for the ground floor which I have purchased from NuHeat with Neostats. Upstairs I have aluminium Rads with a neostat on the landing and a 300 UV cylinder again with a Neostat all of which are hard wired. I have natural gas and am looking at a modulating Worcester 34kw system boiler. I have a 4kw pv system (SW facing and hopefully will fit an immersun) with single panel optimisers and a Beam c130 MVHR system. I have installed the first fix myself and am looking for any suggestions/advice on things I may have missed. I think I am down to about 0.17 on the external walls with 140mm batts and superfoil, osb before plaster board and also used the foil breather membrane on the external timber frame. A Scan 58 log burner has also been purchased as I am looking at cutting down on bills the closer to retirement I get ? . Dare I venture into the AV/networking!! I am dreaming cables at the moment!!! Thanks in advance C

Into detail design stage for an extension to existing stone cottage. Basically a timber clad 2 storey box with a glass link to replace single storey hotchpotch that is there now. MBC have quoted for a passive slab (ouch£!) but due to size restiction will go for u=0.14 walls (open panel , 300mm finished) and u=0.14 flat roof by MBC if I can deal with the + VAT price. Existing gravity DHW gravity fed with pump for shower, supplied by a 2009 year oil fired Grant 15/28 kw utility condensing system boiler that also runs the rads. The rads will have to stay in the cottage but how to run UFH in the extension.. Based on an MBC house build nearby I'm pretty sure I won't need any heating on 1st floor apart from electric towel rads and/or electric mat for en-suite (although they don't have a link to a drafty cottage so slight concern!) Yes I'd like to do away with the oil boiler but not sure I can considering the poor performing cottage and potential costs. I'd like to go mains pressure also so UVC, (mains flow rates of 40 L/m). If so then potential for solar PV or solar Thermal if worth the investment. Do I fit a buffer for UFH to stop short cycling? Any thoughts? Any alternative schemes?
