Hi all
Just installed a gas boiler to replace solid fuel.
Thanks to advice received on this board--gas supply installed-meter
installed--new boiler installed--new gas pipe[internal] installed and
tested--zone valves fitted--complete wiring--new control panel and hot
water thermostat.
System fired up and ran perfectly-------------almost--well chuffed.
My problem is a new radiator was installed-- it is the furthest from
the boiler about 20 feet--it will not warm up.
The TRV works in both directions so I have tried it both ways---no
joy.
I have bled both input and output by slackening the lockshield and TRV
connections to obviate an air lock.
All TRVs were turned off to boost flow to the radiator--no change.
Pump is set at mid range.
The radiator will heat slightly when the bleeder is opened and the TRV
controlled input will get hot.
The whole central heating system is only 3 years old using a "classic"
22mm main ring with 15mm feeds to the rads on the flows from one side
and returns on the other basis.
The system is at normal atmospheric pressure--non-pressurised.
I have run out of ideas please advise.
