Edit for my post above
"Hello again Chris".
Further to my message to You above - I need to submit an Edit to clarify something that I wrote:
EDIT FOR THIS PARAGRAPH ABOVE:
QUOTE:
Depending upon the circumstances regarding the Boiler Interlock this `Built In` Bypass would not really be capable of Heat Dissipation because there is simply not enough pipework to dissipate the Heat - but this should not cause any problems as usually there is always some circulation around the Heating System - unless all the TRV`s were closed at the same time - which could in theory happen.
END QUOTE
I should have written that with MOST Heating Systems connected to a Combination Boiler there would usually always be some circulation path in operation.
This situation can be different when there are Zones engineered into the system which use Electronic Zone Valves - depending upon how these zones are created and where the zone valves are installed there could be a situation where ALL circulation paths are closed - except for the Internal Automatic Bypass in the Combi Boiler.
Obviously this does not apply to your system Chris - but I have written this Edit because of other readers - including other Heating Engineers who sometimes take pleasure in contradicting `Fellow Professionals`.
That is NOT directed at the `Fellow Professional` who posted some useful information on this thread - neilhooper - My comment is prompted by experiences on other Forums.
Regards,
Chris
