Coal Stoves: Direct Vent
The Old House Web
The Harman DVC-500 is the first true direct vent coal stove, and does not require a chimney for installation or operation. All of the air required for combustion is drawn from the outside, and all of the exhaust air is blown back into your home.
An onboard computer (standard with this stove) makes constant adjustments to fuel consumption and heat. At a low setting of 7,000 BTUs, a stoker keeps you from being driven out of the room by too much heat. But when the winter winds howl, the stove can crank out 75,000 BTUs.
The 93-pound capacity hopper holds enough anthracite coal to last for four days without reloading. The oversized ash pan handles ash from an entire hopper's worth of coal.
This stove requires electricity for operation, but an emergency backup battery is available.
