Dometic Small 18,000 BTU Furnace

The Dometic DFSD 20111 18,000 BTU Small Furnace is a compact, lightweight heater boasting a quiet operation thanks to reduced air turbulence. For easy and flexible installation, it may be placed vertically or horizontally. With the most duct configurations on the market, you can distribute heat exactly as you need it.

Dometic has gone above and beyond to provide RVer’s with a furnace that rapidly heats and has maximum air flow. Dometic standouts from the crowd with their tubular pipe design heat exchanger. With smooth and rounded bends, the air flows and heats much more evenly through the pipe without getting “trapped” or slowed down in sharp corners. Not to mention, with less air turbulence, the quieter the furnace!

The Dometic SKU for this furnace is # 9600001165.
