Boiler problems after removing radiator

[Rob Ward]

Hi,
I've been fitting a new bathroom and as part of this I've removed the old radiator and as a temporary measure until I have chance to fit a new one I've joined the radiator inlet / outlet together. before doing this I drained the heating system (with power turned off), then after completion I bled the air out of the radiators to remove any air locks. When I switched the water on after doing this however the gas flicked on and off 2 or 3 times, the pressure rose until the relief valve dumped water out. One thing I neglected to do before switching on was to bleed air out of the pump, which I have subsequently done, along with twisting the shaft with a screwdriver. After doing this the problem remains and I notice that the pump is very hot to the touch. I'm just looking for confirmation that the problem is likely the pump and if it is should I try and fix it or buy a new one + are they easy to fit? Could the cause be something other than the pump e.g. the expansion vessel?

I've a Bosch RX2

Thanks in advance

Rob

no need to respond to this as It's working now, just needed to spend more time purging the pump!

You don't need to join rad valves together when removing rads. Just cap them.
There are methods and devices to purge air from boilers without using the screw in the pump.
Otherwise: glad it's sorted.
