Could anyone please recommend an inexpensive paraffin heater for the
winter. Thanks.

Have you any idea the price of Paraffin?

I'd either run an electric cable to the structure and use a fan heater
or get a gas heater and run it in red bottled gas.
Both cheaper alternatives to Paraffin, and a lot less trouble.
