Title: BAXI 105HE Combi - Minor Leak on Heating Flow Pipe
Post by MisterGriffiths on Mar 20^th, 2011, 12:16pm

I've found a minor leak within the boiler, which I think is on the joint between the heat exchange unit and the Heating Flow (out) Pipe.

I have a couple of questions really.

1) If I turn off the Heating Flow and Heating Return taps, will that stop any further leakage in the boiler. Obviously there will still be some water remaining in the system but no new water entering the system.

2) Can I still run the boiler in Mains Water Heating Only mode with the heating system taps in the off position, or could this cause a pressure problem in the boiler's internal part of the heating system, while the mains water is being heated?

Thanks in advance.

Never run it with heating valves off bud.

Thanks Wayne B that's all I needed to know.

Should hopefully have the plumber today and the sun has come out, which is a bonus.
