Ater a good dicussion with a local plumber it is pretty certain that we will be putting 2 ashp systems in to supply 2 zones, but they will both be in one area next to one plant room. The idea is that 1 big pump (15kW)would be working very hard, whereas 2 x 10 would be coasting and much more efficient. Therefore the feed from the plantroom will need long distribution pipes to the manifold. Ground floor concrete with ufh. Partial First floor is largely in the roof space with timber floor and will be big rads. There will be a convenient void between low walls and the outer wall, through which services can run, and we can insulate inside the stone wall. I think we must take the feed pipe to the first floor so that it can be insulated or we will lose too much heat in transit in the concrete floor. Is it normal or wise to use the specialist insulated pipes, or simply to use normal pipe then pipe-wrap (the superior one) then also wrap in mineral wool. This looks great but is £50/m, and it might be difficult to get round corners. Have used it previously outside from distant ashp to building but is it too much for inside? .
