Thank you for that I shall ensure there is a small circulation of air.

I would use a low wattage electric jobbie, like a tube heater or even a
frost protection fan heater with a good thermostat, it doesn't have to be
very powerful. Or even an underfloor element (available from CEF and most
good electrical wholesalers).

With the price of electricity going through the roof, believe it or not,
the paraffin is cheaper. We are currently trying to change suppliers at
present.

Or even bubble wrap.

Would that be sufficient in, say, March, April with just bubble wrap
alone?

It does, thank you
