We are fortunate to have a used Regency E-21 small gas insert available. This is a nice little insert designed for heating up to about 800 square feet, with a maximum BTU input of 23,500 using Natural Gas. It could use Propane but a kit would have to be purchased to convert it. A blower is built in it, and it has an option of a thermostat. Its price is $800 for the insert; installation materials and labor are not included. It’s in good shape and would help a family, even if the power goes out.
