Help

I fitted a new towel rad to bathroom on the weekend, closed and drained the system, took old rad off, extended pipework to fit new valve centers and hung towel rad, disconnected tied up ball valve and re-filled system.

Slapped myself on back and thought good job, missus well chuffed as finally got rad on wall.

No heat to any first floor rads, bled everywhere till water came out, switched off two ground floor rads in lounge to see if helped, towel rad got very slightly warm, but lounge froze so had to switch rads back on. (moan moan)

This is a 1970's house, proberly original gas boiler and tank (ground floor) no TRV's just old fashioned valves, all worked sweet as, before DIY?

Anyone got any ideas, gonna try and drain individual rads at bleed valve to see if air trapped between ground and first floor (might get it shiffted that way?)

Thanks in anticipation..... :(

system needs balancing properly by the lockshield valves. Google it for a full description how.

Failing this, I would be looking at the pump.

Have had the same problem, shut down all rads apart from one and bleed it. Then turn off that rad and open another. Repeat on all rads and hopefully it will clear air lock. Worked for me :)

Thanks chaps!

Turned them all off but one, and gradually turned the rest on bleeding away as I went!

Worked a treat missus well chuffed, more brownie points than you can shake a stick at. :)
