dear all,
would appreciate some help with the following.
we have a very old concord WRS wall mounted boiler in our garage. for a while now a gated valve above the boiler has been leaking and this was corroding the casing so yesterday i finally got round to replacing it.
the valve was down stream of the electric pump (next to the boiler) which drives the CH.
i slacked off the existing valve, drained the system, replaced valve, fired up the old girl and bled the rads. all seemed well as CH worked fine on testing.
this morning however, no hot water in the storage tank, which is upstairs.
hot taps are running (cold water though), no coughing or spluttering to suggest air. boiler is working and getting hot as expected. storage tank feels cold but sounds like its filling from somewhere.
i assume the pipe i worked on is not the supply to the storage tank the pipe i worked on as;
a) there as 3 other pipe leaving/entering the boiler
b)the storage tank doesn't depend on the CH pump.
i can only guess that air has gone back into the boiler itself?
any advice on how to remedy this would be much appreciated.
cheers,
d
