Our Verdict
The Empire SR18W delivers 18,000 BTU of propane heat. It mounts to your wall and covers up to 500 square feet. It runs without electricity.
This heater works best in garages and workshops. High BTU output handles large, cold spaces well. The wall mount keeps your floor completely clear.
It has no remote control or timer. You adjust settings manually at the unit. Compared to electric heaters, this limits daily convenience.
At $499, the upfront cost is high. Propane fuel adds running costs every heating season. Plan for both expenses before you buy.
This is a strong pick if you need permanent propane heat in a large space. It is not built for bedrooms, desks, or budget heating.

What Could Be Better
