@toodles Thanks for this. I was working on a 'how to fix an LLH/buffer tank without removing it' script and more or less got, in my thought process...
@declan90 Be aware that this might impact COP negatively as you are aiming to increase the emitter DT. In principle higher emitter DT = lower av...

Thanks, thats helpful And painting the outside black... The UI for many makes has not, IMHO, been designed or developed with the user in mind. ...

OK, further to the above (which please do read as its about a different and possibly equally important topic) this plot is a bit of a goldmine! ...
Thats good data. I will compare heating COP (which doesnt seem too bad) with mine later today and make some observations, but I think its worth takin...
