Fan Convectors

A room that never quite warms up is usually a distribution problem rather than a furnace problem, and running new ductwork to solve it is rarely worth the cost or the disruption. That is the situation a vent free gas heater is built for, and a fan convector heater of this type moves the warmth around the room rather than letting it pool at the ceiling. Because combustion stays inside the room and no flue carries heat outdoors, nearly all the fuel you pay for ends up as warmth you can feel. If you are finishing an addition, converting a space, or heating an older building whose original system was never sized for it, this category solves the problem without touching the rest of the house.

We stock the Rinnai fan convector range to the standard contractors specify, and you get that same standard behind a single purchase. Vent free equipment carries real code restrictions, and we would rather you know them before you order than after your installer arrives.

Best Ventless Gas Heaters for...

Small Rooms and Additions

The best ventless gas heater for a small room is a 10,000 BTU unit, since more output short cycles and overshoots the setpoint. The Rinnai 10K BTU Fan Convector Natural Gas suits bedrooms and converted offices.

Cabins and Properties Without a Gas Main

The best vent free heater for a property with no gas main runs on liquid propane, drawing from a tank rather than a utility line. The Rinnai 10,000 BTU Fan Convector Propane fits seasonal cabins.

Open Plan Living Areas

The best ventless heater for an open plan area moves air, because output alone will not reach a far corner. At 215.4 CFM, the Rinnai 24K BTU Fan Convector Natural Gas carries warmth across connected rooms.

Basements and Finished Lower Levels

The best vent free gas heater for a basement pairs high output with propane supply and a cool touch cabinet. The Rinnai 22,000 BTU Fan Convector Propane handles finished lower levels off the gas network.
