[C320-list] Bleeding calorifier for cooling?

[Graeme Clark]

Thanks all for the help and suggestions; sorry about the unusual terminology - I think it helps us instantly distinguish whether someone is talking about the hot water being heated by engine hot water, or being heated by an electric element!  But I had never heard the term either until I started sailing in the UK!

I’ll double check everything when next on the boat

Thanks

Graeme
