Hi all
My idiot builder who took a year to not complete my extension has run the flow and return pipes to my UFH manifold in 15mm from the feeds to an old rad instead of the usual 22mm from the boiler.
He didn't get as far as buying the 2-zone manifold, so I've got all the gear ready to plumb in. Pump, manifold, 2-port zone valve, wiring centre and actuators. I'll be controlling the 2 loops separately via a Tado thermostat in each room.
Loop 1 is about 15 sq m, pipe length 50m.
Suspended timber floor with 16mm pex-al-pex pipe laid in biscuit screed between joists on top of insulation.
Loop 2 is about 35 sq m, pipe length 100m.
Half solid floor, the rest is same as loop 1, but with big bi-fold doors.
Does anyone know whether the system would run well off the 15mm pipes? I know it would be better to run new 22mm pipes from the boiler, but I'd probably end up calling a plumber in for that, so want to know whether it's essential or not.
I'm tempted to just plumb it all in using the 15mm pipes with reducers for now and see how it goes.
TIA
