Hot days encourage bold RV owners to pick up their belongings and hit the road. For those who enjoy a late season ramble, though, life on the road can be uncomfortable without a heating system. Namely, air heaters are designed to keep chilly passengers warm while they cruise past snowy mountains. If anyone has ever wondered how air-blown heating works, keep right on reading.

Wintery Warmth and Motorhome Freedom

Should RVs be put into storage when the first snowflakes fall? No, not at all, not when some of the finest sights only appear after the cooler seasons arrive. The trees in one part of the country turn red and brown when autumn appears. Then there are mountain ranges and national parks that look more majestic when they’re blanketed in snow. Keeping RVs on the road during the winter, ducted heating systems blow hot air from one end of the cabin to the other.

Follow the Air Blower Ducting

Cleverly concealed vents are often located low on a cabin wall. As the warm air breezes through metres of ducts and vents, it rises on a warm current. The first vent, of course, is located at the inlet panel. It’s here that the cold air conduit sucks in outside atmosphere and channels it towards the box-shaped air burner. Importantly, the latest appliances operate on diesel fuel, so they use the vehicle’s fuel tank as an energy source. Then, with the combustion blower in full flight, the atmosphere is passed into a sealed combustion chamber, which then uses a special glow plug and heat exchanger technology to transfer the hot air to the air outlet port.

Balancing the Air Blower Housing

It’s a compact piece of equipment, this small combustion chamber and its inline fans. Cold air comes in, hot air exits, and the burnt fuel is discharged through an exhaust section. Meanwhile, the entire assembly is microprocessor controlled. The temperature sensors, hot air impellers, even the heat exchanger, all of the sections are precisely regulated by that control circuitry, which is integrated as part of the air blower module. Finally, to really ensure efficient operation, the system should be sized so that it matches the needs of a chosen recreational vehicle. Fuel intake ratios are first in this tabulated data, then fan-powered heat output and power consumption.

Two lines of power/fuel are employed as a mobile air blower’s drive source. Electric power provides sparking energies, combustion and microprocessor control. For raw fuel, though, it’s the RVs fuel tank that delivers the combustible fluid to the ignition chamber. And this isn’t the end, not just yet. Incorporated into high-performance air blowers, there are different mounting options, quiet operating modes, programmable cabin controls and much more.
