Evening all
I'm hoping there are some plumbing experts on here that can help me as my main contact (cousing who's a British gas fitter) has been talking me though it but is offline for the next few hours.
Long story short, I turned on the guest bedroom rad yesterday morning as it was feeling a bit chilly in there (it hadn't been on since Christmas) and within minutes had water pouring out from around one of my ceiling mounted speakers in the lounge :shock:
Managed to get a view of the problem today and it was a dodgy solder joint behind the wall on the return leg from the rad. The joint was heavily oxidised so must have been weeping for a good while but I guess going from cold to hot must have sprung the joint open.
I drained the system down and removed the rad, sweated the dodgy joint off, cleaned up and sweated a new elbow on. Job's a guddun
Took my cousins advice on filling the system (opened bleed valve on replaced rad and opened filling loop until water came forth, the repeated around the other 2 rads on the loop). SWMBO managed filling loop while I bled rads (we kept in contact by walkie talkie ) and pressure is currently at its normal operating pressure of 1.5Bar.
Heating is now fired up and the downstairs underfloor heating is toasty again, the bathroom towel rails are boiling but the 3 rads are stone cold!!!
All 3 heating methods are off the same boiler/pump so can't understand how the u/f and towel rails can be hot but none of my rads. I have checked and quadruple checked all isolation/stop taps to make sure they are all open, and the flow/return pipes from boiler to rads and boiling but it's just not getting into the rads.
System is pressurised (no tank) oil fired boiler with single flow from boiler branching to 3 different systems/zones (ground floor underfloor-working fine, 2 guest bedroom ensuite towel rails-working fine, 2 guest bed and one landing rad-all colder than a penguins tatties).
Can anyone tell me what I've done wrong?
