Our Verdict
This Empire SR18TLP runs on liquid propane and delivers 18,000 BTU of infrared heat. That output is 3.5 times more than the best electric space heaters can produce.
The hydraulic thermostat holds your set temperature without manual adjustments. Overheat protection adds a layer of automatic safety. These two features support long, unattended heating sessions.
The $819 price puts it far above typical home heaters. You also get no remote, no timer, and no tip-over protection. That missing feature list matters if you compare it to electric options at a fraction of the cost.
For garages, workshops, or spaces without reliable electricity, propane power is a clear advantage. Most electric heaters simply cannot match this unit's output. It solves a specific heating problem that most products cannot.
