Hello, I am in the process of renovating my house and I now have to choose the UFH system/components. I am doing everything by myself, I am on a tight budget and i have never done one before. I have gone through several manufacturer website, installation guides but I can't figure out which manifold, pipes, actuators and pump would be best or which to avoid. I don't mind buying the whole lot from one source or each components from different sources as long as they are compatible and of a decent quality. Some more info: -UFH on whole house (no radiators except towel rails), 65mm screed on 120mm insulation on ground floor, 25mm screed between joist on 1st floor. -7 zone on ground floor, 8 zone on 1st floor - I already have 12 Heatmiser Slimline-N - 12v thermostat, I guess they are only compatible with the UH8-N wiring centre. My best guess: Pipe type: 16mm Pert/Al/Pert Manifold, pump and blending valve: Pre-assembled block? Actuator: not sure which (230v or 24v) are compatible with UH8-N wiring center Any advice is really appreciated.
