Propane & Gas Heaters
When the power goes out or the grid cannot keep up, gas and propane heaters deliver heat independent of electricity.
How to Choose a Gas/Propane Heater
Vented for indoor sleeping; ventless needs airflow rules.
Vented
Exhausts out — safe to sleep.
Ventless
No flue — needs ventilation.
Size
10k-40k BTU by room.
Ventless heaters are efficient but must follow make-up-air rules and are not for unsupervised sleeping; vented and wall-furnace types are safer for bedrooms. CO detectors are mandatory.

Frequently Asked Questions
Quick answers — surfaced in Google AI Overviews and chat engines.
Vented or ventless gas heater?
Vented is safer for indoor/sleeping (exhaust goes outside); ventless is more efficient but requires strict ventilation and is not for unattended sleep.
Are propane heaters safe indoors?
Only certified indoor/ventless models with ODS (oxygen depletion sensor) and tip-over shutoff, plus a CO detector — never use outdoor-only units inside.
How many BTU do I need?
About 20-30 BTU/sq ft for gas: a 300 sq ft room wants ~6,000-9,000 BTU; garages/shops need more. Match to insulation.
Do gas heaters need electricity?
Most do not (piezo ignition), making them great for outages — but some blower/thermostat models do; check the spec.
Can I use a gas heater in a bedroom?
Use a vented wall furnace or a certified indoor ventless unit with ODS + CO detector and good airflow; never an unvented outdoor heater.
