Frequently Asked Questions

Are HearthRite vent-free heaters safe?

Yes — all HearthRite vent-free models include an ODS (oxygen depletion sensor) that automatically shuts off the gas if oxygen levels drop. They run at 99.9% efficiency. Always follow the BTU sizing guidelines for the room (1 BTU per cu ft of well-insulated space).

What size HearthRite do I need?

Sizing rule: 1 BTU per cubic foot of well-insulated space. A 10,000 BTU heater warms ~125 sq ft (1,250 cu ft, 10' ceiling); a 30,000 BTU heater warms ~375 sq ft. Undersize rather than oversize for vent-free.
