How Does the 10K BTU Compare to the 20K BTU Model?

HeatStar Blue Flame propane heaters are available in two BTU outputs:

• 10,000 BTU — $230 — covers up to 300 sq. ft., freestanding only, ships in 1–2 business days
• 20,000 BTU — $316 — covers up to 700 sq. ft., wall-mountable or freestanding, ships in 1–2 weeks

The 10K model is the right choice for smaller greenhouses or spaces under 300 sq. ft. where the 20K would be oversized. Both models require the Remote Propane Vent-Free Installation Kit and cannot ship to California.

Does This Heater Require an Installation Kit?

Yes — this heater requires the Remote Propane Vent-Free Installation Kit for proper installation. The kit can be added to your cart separately or bundled with the heater at checkout. Do not purchase this heater without also ordering the installation kit.

Does It Work During a Power Outage?

Yes — the HeatStar Blue Flame Heater operates without electricity, making it a reliable heat source during power outages. The electronic ignition runs on a single AA battery (included). The built-in 110V blower fan requires electricity to operate, but the heater itself will still produce heat without it.

Is This Heater Safe for Greenhouse Use?

The HeatStar Blue Flame is a vent-free propane heater with a built-in low oxygen shut-off (ODS) sensor that automatically shuts the heater off if oxygen levels drop below a safe threshold — a critical safety feature for enclosed spaces like greenhouses. It is CSA certified for use in the USA. Note: this unit is not approved for use in bedrooms. Ensure adequate ventilation in your greenhouse when operating any propane heater.

Can This Heater Ship to California?

No — this heater cannot be shipped to California due to state regulations on vent-free propane heating products. If you're in California, contact the Grandio team to discuss alternative greenhouse heating options.
