Tip-Over Safety Switch - Integrated sensors immediately shut down the unit if accidentally knocked over, preventing fire hazards and ensuring user safety.
Piezo Ignition - Push-button ignition eliminates the need for matches or lighters, providing safe and reliable startup every time.
Thermoelectric Safety Valve - Monitors pilot flame and automatically shuts off gas flow if flame is extinguished, preventing dangerous gas accumulation.
CSA Certification - All indoor-safe models meet rigorous Canadian Standards Association requirements for safe operation in enclosed spaces.

How to Size a Heater

Choosing the right heater starts with knowing how much heat your space needs. Heater capacity is measured in BTUs (British Thermal Units).

Measure your space: Calculate the square footage (length × width).
Factor in conditions:
- Well-insulated indoor space: 25–30 BTU per sq. ft.
- Typical job sites: 40–60 BTU per sq. ft.
- Drafty or exposed areas: 60–80 BTU per sq. ft.
Do the math: Multiply your square footage by the BTU per sq. ft. for your conditions.
Choose slightly higher capacity: Select a heater with reserve power to ensure comfort and efficiency.

Frequently Asked Questions

Is Mr. Heater a good brand?

Yes, Mr. Heater is widely regarded as a leading brand for portable propane heaters in North America. It is known for its reliability, innovative safety features like the Oxygen Depletion Sensor (ODS), and durable construction, making it a trusted choice for both professional and recreational users.

Is a Mr. Heater safe to use indoors?

Many Mr. Heater models, especially those in the Buddy series, are certified for safe indoor use. These heaters include safety features such as an Oxygen Depletion Sensor (ODS) and a tip-over switch. Always follow the manufacturer’s instructions and ensure proper ventilation when operating a propane heater indoors.

How long does a Mr. Heater last on a propane tank?

Runtime depends on the heater model, BTU setting, and propane tank size. For example, a Portable Buddy Heater running on a 1 lb. propane cylinder may operate for about 3 hours on high or up to 6 hours on low. When connected to a standard 20 lb. propane tank, runtime can exceed 100 hours depending on heat output.

Can you run a Mr. Heater in a garage?

Yes, certified indoor-safe models such as the Big Buddy Heater or Cabinet Heater can be used in a garage if the space is properly ventilated. Always allow fresh air circulation by cracking a door or window and never operate outdoor-only heaters, such as tank top models, in enclosed spaces.

Is it cheaper to heat with electricity or propane?

The cost depends on local electricity and propane prices, but propane heaters are often more cost-effective for spot heating and temporary applications. Mr. Heater propane units deliver high BTU output without relying on grid power, making them ideal for job sites, garages, power outages, and unheated spaces.
