Hello,
Currenly doing an extension and renovation of a 1930s semi detached house in South Manchester. I’m not a plumber or tradesman and have come up with the attached plan by research, dangerous I know!
5 Zones UFH
Living/dining room
Kitchen
Utility
Sitting room
Hall
The majority of the house is suspended wooden floors with a void approx 500mm, the extension which includes kitchen, utility, part of the hall and dining area is concrete.
The concrete areas have 100mm of kingspan embedded within, I was planning on fitting 100mm kingspan between the joists below the floorboards, the 250mm kingspan over the top of everything, 16mm UFH pipe then wet screed approx 35mm.
The majority of pipe is laid at 200mm centres, all zones will be controlled using Heatmiser NeoStats. In the living and sitting room we will have gas fires. Upstairs will be radiators in most rooms, I was planning on using a manifold to create separate zones for these rooms and installling electric UFH in the bathrooms, don’t have the height to run wet UFH.
I’ve attached my pipe layout plan, your thoughts would be appreciated.
