Empire Industries HBW20TL Vent-free Blue Flame Heater 20000 Btu/h

Product Description

The EMPIRE INDUSTRIES HBW20TL is a vent-free blue flame wall heater fueled by liquid propane (LP), rated at 20,000 BTU/h. Blue flame technology heats air by convection, warming the room from floor to ceiling in a pattern similar to a central heating system. The unit includes an integrated thermostat for automatic temperature control, allowing the heater to cycle on and off to maintain a set comfort level. This type of supplemental or zone heater is installed by licensed HVAC technicians or qualified gas fitters in residential or light-commercial spaces where a dedicated flue is not practical or desired.

The HBW20TL is suited for residential applications such as living rooms, bedrooms, garages, workshops, and cabins where LP gas service is available and no exterior venting is feasible. Its vent-free design eliminates the need for flue pipe or chimney access, making it a practical choice for zone heating or backup heating in LP-served buildings. The thermostat control makes it appropriate for spaces that require maintained temperature rather than radiant spot heat.

Key Features

• 20,000 BTU/h output — sized for supplemental or primary zone heating in small to medium spaces
• Vent-free design eliminates flue or chimney installation requirements
• Blue flame convection heating distributes warm air throughout the room evenly
• Integrated thermostat control cycles the unit automatically to maintain set temperature
• Liquid propane (LP) fuel — compatible with standard LP supply systems

Compatibility

Designed as an OEM-style vent-free LP blue flame wall heater for residential and light-commercial supplemental heating applications where liquid propane service is present and no exterior venting is available.

Installation Notes

Installation must be performed by a licensed HVAC technician or certified gas fitter in accordance with the International Fuel Gas Code (IFGC) and all applicable local codes. Shut off the LP gas supply at the tank or meter before making any gas connections. Vent-free heaters require the room to meet minimum volume and air-supply requirements as specified by the manufacturer and local code — verify square footage and cubic volume ratings before installing. Do not install in bedrooms, bathrooms, or other spaces prohibited by local jurisdiction without confirming code compliance.
