Yep, the blast of heat ruptures the plants cells and they wither.

Haven't used mine for about three years so it's probably stopped
working, not sure where you'd take it to get it serviced ...

They are pretty simple devices, there isn't a lot to service or go
wrong. The jet may need a prick from time to time but that's about
all.

... but getting paraffin was unusually difficult too!

Odd, almost every garden store/section that has greenhouse heaters
has paraffin, at a price of course. Domestic heating oil is the same
stuff but without "a pleasant fragrance" or the pink or blue colour.

Paraffin and heating oil are 28 second petroleum fraction, diesel is
35 second. Undemanding applications generally work ok with diesel, and
I expect this is one such.
