Continuing to be haunted by this heating system, I've now put a new ST6400c programmer on, and all seems to be well. I'm now trying to balance the system - which I think is a S plan (2 MV's in loft, 1 pump, cylinder stat and room stat).
However, the HW header tanks have an expansion pipe, but the F&E tank does not, and if most of the rads are closed off, hot water bubbles up the flow pipe of the F&E until the boiler shuts down.
Is this in order? I'm confused even more now? Comments please?
Thanks John
