Good afternoon all. I've been doing a lot of research on how best to install UFH in my Victorian Terrace but have come across some conflicting information from a couple of the suppliers I've been in contact with. Ideally, I would like to have a 10 port manifold and pump mounted centrally on the ground floor (cupboard under the stairs) near the boiler and rise the UFH pipework pretty much centrally to serve the two floors above (first floor and loft conversion). One company says this is fine and has quoted accordingly, whilst the other has said it can't be done and I would need a pump and manifold for each floor. I can't seem to find anything online to corroborate either opinion.... Obviously, having a manifold and pump on each floor would push the cost up significantly, not to mention casue extra hassle with the plumbing to / from the boiler, so I really want to go with just the one manifold arrangement. I've not calculated loop lengths yet but this isn't a massive place; just a typical working class two up - two down terrace with one up - one down rear extension. All informed opinions are most welcome. Thanks very much Graham
