Refilling central heating system floor standing boiler

[kim11]

I've just drained the whole system (I know mistake) to add a new radiator, now system won't refill. The boiler is an Ideal Mexico floor standing one.

something is wrong

..........but what?

 

[gavinda]

is the header tank full?

 

[kim11]

yes, pushed the ball cock down a couple of times, it's working

 

[kim11]

On the pipes coming out of the boiler are 2 red taps, which are fully opened. Do these have anything to do with the pressure, remember its an old boiler?

 

[gavinda]

if you didnt touch then to begin with they shouldnt make adifference. they could be anything tbh. what was the water like when you drained it... balck /orange?

 

[kim11]

The water's a greyish colour.

I opened the valve opposite the bleed valve and it was quite oily looking.

 

[gavinda]

could be a bit mucky and cold feed is blocked..

i take it you've tried all the air bleeds.

could be worth knocking the boiler stat off and running the pump for a minute.

 

[kim11]

Yes I've tried all the air bleeds. Tried running the pump but its starts making a noise and I'm worried i'll break that too. Whats the stat?

 

[kim11]

Thermostat? Tried & still nothing

 

[kim11]

How do I unblock the cold feed

 

[gavinda]

fittings, pipeslice, copper, hour and a half.

you need to find your cold feed/ open vent entry to the system. trace the pipes from the header onto the heating.

That sounds a bit complicated for my female brain, should i try anything else before i have to take the new rad apart
