December 8, 20232 yr Good Day Team, Im a plumber gas fitter from New Zealand and have been ask to install pipe work from a boiler to underfloor heating manifold, i just want to assure ive got this correct before i proceed. The manifold has been installed by others and ive supplied the boiler. They have left behind the wiring centre, 2 thermostats, 1 zone valve and the actuators. System only 13 KW electric boiler supplying a 2 zone underfloor heating manifold, if someone could confirm the valving is correct that would be appreciated. Do i need a automatic by pass valve or is a standard gate valve in the open postistion okay? Ive attached a rough sketch some advice would be appreciated. Usaully the supplier would give me all this info but i cannot get that from the supplier here (not very helpful). Cheers UFH draft.pdf

Looks like it will function fine if installed as per the diagram tbh, just down to how well the boiler can modulate / cope with low heat loads (when the rooms get up to temp). 5 wire zone valve I assume, so the boiler can't fire until the ZV is fully open?
