Well perhaps not BS2869 Class C1 but 28 sec heating oil (BS2869 Class C2)
is only marginally heavier. 28 sec heating oil will still work just might
be a bit smelly compared to "paraffin" produced for non-flued heaters.
The sulphur content of heating oil is higher but I doubt that is
particularly significant.

It is very risky, and in my opinion not worth the risk.

Heating oil is around 60p/l, minimum delivery from a heating oil supplier
is probably 500l though. You might be able to buy a smaller quantity if
you collect or find a neighbour with oil fired central heating?

I wouldn't touch heating oil with a barge pole.
I've seen a crop of over 2000 tomato plants wiped out overnight when a
flue blocked and the fume from a heater filled the glasshouse.
Another time a cucumber crop lost the same way, Sulphur burns the
foliage of the plants, some are a little more tolerant than others.
We used to clean out glasshouses by burning piles of sulphur and
Nicotine shreds in closed down houses then leaving them for 24 hours.
