CheapHeat™

Until now the standard for heating RV's has been to use bottled propane (LPG). With the CheapHeat™, that's no longer the only option. How about a choice to change the central heating system between gas and electric with the simple flip of a switch? When you choose to run on electric heat rather than propane, your coach will be heated by the electricity provided by the RV park.

With the CheapHeat™ system it’s not uncommon for even "full timers" to go up to one year or more without having to refill their propane tanks. Now the propane is only being used for incidentals like the stove, or in some cases the hot water.

How It Works:
There are two different configurations that manufacturers use when installing central heating in a Recreational Vehicle. The first way is shown in the left picture and is called a plenum system trunk line fastened directly to the furnace with floor registers).

The second way is shown in the right picture and is called a ducted system (individual ducting runs of 4” pipes). In both cases, the CheapHeat™ system consists of an Add-on Cabinet with an electric Heater Element, the Controller, the Remote Override Switch and Installation Kit.

CheapHeat's Electric Forced Air
by: CheapHeat User

The CheapHeat™ system consists of a UL certified and RVIA compliant stand-alone add on Duct Heater and Controller for mobile vehicles. This product connects directly into the ductwork of the existing central heating system allowing the user to switch between Gas or Electric as a heating source for the Recreational Vehicle. As a UL certified product our system meets, or exceeds, all NEC (National Electric Code), NFPA (National Fire Protection Association), and ANSI (American National Standards Institute) specifications and standards for Recreation Vehicles both in the United States and in Canada.
This product is unique in its’ design because it does not affect any RV gas furnace ANSI listings. In the same way that a conventional residential or commercial gas furnaces does not change the ACCA, UL, AHRI, and ANSI listings or standards when a 3rd party Duct Heater, or AC coil, is added into the existing ductwork. Our system does not use any of the LPG furnace electronic controls, gas controls, or safeties. It actually enhances the gas furnace overall operation, comfort level, and longevity. Additionally, there are benefits associated with the firebox, fan motor, and airflow as listed below:

Blower fan life
• CheapHeat™ increases fan motor life because we have no Pre-purge or Post-purge for each heating cycle and, as a result, the overall fan run times are reduced.
• CheapHeat™ increases fan motor life because our system eliminates the 400 to 600 degree heat on the flue gas fan blades, during the heating cycle that would transfer to the motor shaft. This will overheat the shaft bearing and prematurely seize the fan motor.
Firebox rust
• For the customer that does not want to use their gas furnace and prefers to use an alternative heat source, they have the potential of moisture being drawn into and rusting the firebox. But, with our system, the firebox is kept warm so that it does not draw in moisture and rust.
Airflow
• Improved because all of the ducts are moved to the end of the furnace cabinet (reducing back pressure on the fan motor). This allows the airflow to have a straight path through the firebox with no 90 degree duct take off of from the sides or the top and bottom of the furnace before the air has a chance to passes completely across the firebox.
Improve Comfort Level Both Gas and Electric
• Because the air static pressure has been reduced by the new arrangement of the ducting runs, it means that the longer runs will have greater airflows. This helps to equalize the temperature through out the entire coach.
Increases Firebox life
• With all of the duct runs moved to the end of the firebox, this eliminates the need for duct runs of off the sides and bottom of the furnace cabinet, and stops hotspots thereby reducing premature firebox burn out.

Sub Floor heating

There is already a sub floor heating system made by Aqua-Hot, it cost about $9,000.

RV heating system
by: Jeffrey Greenspan

Do you sell and install sub-floor heating systems for RVs. I want a heating system installed under the floor of my RV that runs on electricity and can be switched over to propane. The propane part of the system would consist of a gas heated fluid being pumped through tubing installed under the floor. And the electrical part of the system would consist of wire heating elements, also installed under the floor right along with the tubing. I think that sub-floor heating is the best way to go for a whole bunch of reasons. A dual energy system would be sooo perfect. Warm floors, dry radiant heat rising to warm the coach, no residual condensation, no lack of air quality to breath, no need for a fan (although, in the propane mode, a fluid pump would be necessary) I even have a fantasy of having solar charged batteries to run the electrical system.
