Underfloor heating problem

[Baz178]

Hi, quick question bought a house a few years ago with underfloor heating up and down but since Saturday you have to turn one of the room on upstairs for down stairs to work! Everything fires up down stairs but doesn’t seem to draw hot water from boiler. Any ideas ? Easy fix ? Thanks

Depends on how they are controlled. If they have a central controller and the controller manages the call for heat - so it zone stat calls to controller > controller opens actuator and calls to zone valve/boiler/pump. Need to understand if the controller is at issue, if it is then they are usually electronic and not easily repaired.

Every room in the house his controlled by wireless stats. When I turn one of the room downstairs the manifold lights up, then the pump kicks in a minute later which gets the boiler working but once the boiler lights it doesn’t seem to pull hot water through.

Anybody help

If the manifolds have mixers and manifold pumps, is the manifold pump running d/stairs?, are there flow meters on each loop?, a photo would help.

All on separate loops to each room and go back to one main fold down stairs! Upstairs his same with a manifold upstairs.

If you turn off the u/stairs do the d/stairs flow meters still read more or less the same?
