It’s only dropped twice, both times when it was around 4c outside. Radiators are bled, very little air in them.
No drips as the overflow pipe is plumbed in to the sink drainage pipework.
I’ll keep a very close eye on it over the next few days, I’m off to sunny hot Norway for a weeks cruise next week and my son is coming here to cat-sit for me. I was supposed to be going back to Majorca with my daughter but the day after we booked it she remembered she’s in Edinburgh at ComicCon, she spent over £500 on VIP tickets and can’t cancel.
It was cheaper to do a change of name than re-book the cruise for next year so now I’m going with my ex-wife!, luckily we probably won’t kill each other!, we’ve survived two trips to Majorca in the last year so we should be ok, and I feel better having someone with me in case I have any medical problems.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
