Yes, you are right - don't waste time (and water) draining the cold header tank when you could use bungs to block the flow. That is the other thing I learned. My friendly local plumber was nice about that too.

Thanks for the thoughts.
Had to call in the professionals (my friendly local plumber Dave Halpin from Gasworks London) in the end when i realised I definitely had air in the hot water cylinder (caused by running the shower when the cold water header tank was empty, thus pulling air into the...
I had to drain the cold water tank to fit a new thermoelement in my Grohe shower.

The domestic hot water is timed for 30 mins after the heating. This morning that was 7.15am. I don't think a valve is faulty.

I would say the leak is slight. I wasn't aware of it before it was serviced. But now I can hear the small 'explosive' sounding drops on start up but I can't hear them once temperature is reached (unlike the last time the HE was replaced).
The BG engineer said it was the HE, not the gasket...
My house is heated by a Baxi Bermuda 675C back boiler. BG tell me it's from 1977. They refused (First Inspection) to take it on a Homecare contract (stated heat exchanger leaking) but quoted to replace the heat exchanger (in writing part number 364574) for £436.
I've used the boiler with just...
