Hopefully just finished our UFH design. This is for a non certificated passive house. The house is a timber frame with passive slab using AFT .The house is on a North/South axis with South being at the right hand side of the drawing. I am hoping people could cast their eyes over this pipe layout. At the moment it has come out needing a 12 port manifold and the spacing is 200mm.
My query is whether I have over done the amount of pipework and if this could be reduced. With the one room upstairs (not on the drawing but positioned directly above the Northern end of the house) I have not bothered with UFH but not sure whether to get a bigger manifold which starts to get expensive, just to put electric ufh to go with the bathroom and all of which may never be used if the house is as warm as we hope. All bathrooms will be electric UFH and any spacing you see, as in the long corridor, will be evenly spaced on the day of laying the pipes.
TIA
