Supplemental Electric Heat
For travelers looking to stay comfortable when the temperature drops, RV air conditioners with heat can provide a practical solution. Instead of immediately firing up your furnace on a chilly morning, a dependable RV rooftop air conditioner with heat lets you take the chill out of the cabin using campground shore power.
The Fogatti InstaCool series utilizes built-in PTC electric heating to deliver supplemental warmth. While a camper air conditioner with heat won't replace your primary propane furnace in sub-freezing conditions, it can help handle mild cold during early spring or late autumn trips.
Use campground shore power to run your RV AC with electric heat and save gas reserves for off-grid travel.
Self-regulating PTC elements provide gentle heating and are designed to reduce overheating risk.
Built to accommodate standard 14.25" x 14.25" roof openings for many existing RV setups.
When exploring options for RV climate control, you may see models featuring PTC (Positive Temperature Coefficient) technology. In short, PTC electric heating provides supplemental warmth built directly into the rooftop unit. It offers a practical way to handle mild cold without immediately relying on your main heating system, making RV air conditioners with heat a sensible option for extending your camping season.
Unlike traditional bare-wire heaters, PTC elements use specialized ceramic materials with self-regulating properties. As the ceramic components heat up, their electrical resistance naturally increases. This physical property helps moderate power consumption and reduce the risk of overheating. The result is a more stable source of warmth with fewer sharp temperature swings than older-style electric heating elements.
An RV AC with electric heat is well-suited for early spring trips, late autumn getaways, chilly mornings, and cool evenings. By running your unit on campground shore power, this supplemental electric heat can help maintain a comfortable indoor climate while conserving propane for off-grid travel or colder conditions.
PTC technology is not a heat pump, and it is not intended to replace your primary propane furnace. While it can help manage mild cold and keep you comfortable during transition seasons, a rooftop unit equipped with electric heating is generally not designed to provide the primary heat required for sub-freezing winter conditions.
In severe weather, your RV's built-in furnace remains important for protecting plumbing and keeping the interior properly warmed.
An RV air conditioner with heat combines standard rooftop cooling with a built-in heating element, such as a heat strip or PTC heating. It functions primarily as a cooling system during summer but can provide supplemental heat for chillier weather. This allows you to warm your cabin using campground shore power while saving propane for more demanding cold conditions.
No, they operate differently. An RV AC with heat uses electrical resistance, such as a built-in electric heat strip or PTC heating module, to generate warmth. A heat pump reverses the cooling cycle to extract heat from outside air. Electric heat is designed to provide steady supplemental warmth during mild temperature drops without relying on exterior ambient heat.
No, built-in electric heat is designed to provide supplemental heat, not to act as a primary winter heating source. Select Fogatti models provide around 5,120 BTU of electric heat, while an RV furnace is typically much more powerful. During freezing or sub-freezing conditions, you should still rely on your propane RV furnace to properly warm your living space.
Electric heat is most useful during spring and fall when temperatures are mild but brisk. It works well for removing the morning chill or keeping the cabin comfortable at night. Because this supplemental heat runs on 115V campground shore power, it can help conserve propane when your main RV furnace is not needed for light heating demands.
For medium-to-large RVs, the Pro 18K features 18,000 BTU cooling, 5,120 BTU PTC heating, and 52 dB operation. The 15K Heat & Cool model offers 15,000 BTU cooling with an electric heat strip at 59 dB. For more compact spaces or non-ducted setups, the smaller-capacity 110P may be a better match for lighter temperature demands.
Fogatti units are designed around the standard RV roof opening of 14.25 by 14.25 inches, which accommodates many existing setups. However, you should verify your vehicle's layout before purchasing. Check your actual roof opening, roof thickness, rooftop clearance, and available 115V AC / 12V DC / 60Hz power supply. Also confirm whether your system requires a ducted or non-ducted setup.
