Just buy central heating oil c2. 49p per litre.@fizzy thanks for posting this, there are a fair few recent posts on the same theme - but it's the season..
The "best" type of heater for my needs would be this ilk.
Running a 3kw electric fan type & charging a hybrid off the same garage supply plus tools etc and needing to heat a new workshop shed aint working out.
But, "never buy in season" a stove maker mate used to tell me, so ballsing it out until spring when they will come down in price.
But as at @waddycall what is a good source of C1 grade paraffin in cica 20L quantities ?
