Crap but it cold here. Not by normal standards, but every winter there is a cold snap that Roman heating just cannot cope with. Not worth planning for, and investing in, I suppose. But still crap.
@phoneboy That seems like an awfully large permitted discrepancy, especially if it is always in one direction.
@phoneboy I'm convinced you are correct. Which is why I have been trying hard to evaluate.
