I have drained my central heating system, which is powered by a combi
boiler, but am now having difficulty refilling it. All radiators are
empty and bleed valves open. Are you able to offer suggestions? I have
a sneaky feeling combi systems are not that easy to refill. Not a major
problem really as I am having a new condensing boiler fitted within the
next two to three weeks so can probably do without heating until
then..but it is getting a little chilly in rural Bedfordshire!
Appreciate any advice you can give.
Thanks
Chris

Would you like to tell us precisely what difficulty you are
having in refilling it? It's so easy that I feel slightly baffled
as to what difficulty you are experiencing. You turn on the
valves on the filling loop ( built in or add-on ) and pressurise it to, say
1.5- 2bar whilst looking at the pressure gauge, turn off filling valves,
then bleed radiators, then repeat until all air is out ( you can open all
bleed valves on the rads and rush around closing them off as they fill up
and start leaking, but it's fraught, your walls will get doused, and you
will have to get to the filling loop to turn it off pronto after the last
radiator is full else the system pressure will skyrocket and blow off via
the overpressure valve. )

Final system pressure should be about 1.5 bar usually.
