How to install the CheapHeat system

The CheapHeat system is an add-on module that enables you to run your furnace like a large space heater, using AC power from shore or generator connections to heat your RV instead of propane. This system is designed to address the limitations of standard electric or gas furnaces in RVs, such as high fuel consumption, uneven heating, or inadequate insulation. It provides an affordable, efficient, and versatile heating solution.

To install the CheapHeat system, follow these steps:

Firstly, ensure you have the correct model for your RV. There are three models available, so you can choose the one that best fits your furnace and usage needs. The system requires a 50-amp service, so make sure your RV park can accommodate this.

Next, the unit is mounted directly downstream of the existing gas furnace. The CheapHeat system employs tungsten heating coils powered by 120 or 240-volt AC to generate heat. A 12-volt fan motor on the furnace pushes the heated air through the ducts in the RV. The fan motor only operates when heat is being produced in electric mode, which is a key difference from gas furnaces.

The CheapHeat system also includes a solid-state controller that communicates with the existing wall thermostat and the fan motor. This allows you to easily select between "Electric" or "Gas" on a wall switch, depending on your preferred energy source.

Finally, you can enjoy the benefits of your new heating system! The CheapHeat system is deemed safe, as it has redundant integral safety measures, and no carbon monoxide is produced when using electric heat. It is also energy-efficient, reducing propane consumption and extending your fuel reserves. With the CheapHeat system, you can stay warm and comfortable wherever your RV adventures take you.

How to choose between propane and electric heat

When it comes to choosing between propane and electric heat for your RV, there are several factors to consider, including cost, convenience, and efficiency. Here are some key points to help you make an informed decision:

Cost

The cost of propane vs. electricity is an essential consideration for many RV owners. Propane is generally considered the cheaper option, especially if it costs less than $3.14 to $4.47 per gallon. However, electricity can also be cost-effective, depending on your usage and the regulations of your RV site. Some campsites include electricity in their fees, making electric heating a more economical choice in those cases.

Convenience

If you frequently camp off-grid or engage in boondocking (camping without hookups), propane heaters may be more convenient since they don't rely on electricity. Electric heaters require a reliable power source, and while generators can be used, running them all night is not recommended. Therefore, if you prioritize flexibility and independence in your RV adventures, propane might be the preferred option.

Efficiency

Electric heaters are often more efficient than propane heaters. Most electric heaters are 100% efficient, while RV propane furnaces typically operate at 70-75% efficiency or even lower. This means that with propane, more energy is lost as heat escapes, resulting in higher costs to maintain the same level of warmth.

Safety and Ventilation

Propane heaters require proper ventilation to reduce the risk of carbon monoxide poisoning. Electric heaters, on the other hand, are clean-burning and do not produce harmful emissions, making them a safer choice from a ventilation perspective.

Temperature Considerations

The temperature range you expect to encounter during your RV trips is another factor to consider. Propane heaters tend to add moisture to the air, which can be beneficial in drier climates or seasons. Electric heaters, in contrast, provide dry heat, which may be preferable in humid conditions.

Camping Frequency and Duration

How often and for how long you camp in cold weather also plays a role in your decision. If you only occasionally camp in cold weather, sticking with your built-in RV propane heater or a simple upgrade like a ceramic space heater may be the most sensible and cost-effective choice.

In summary, both propane and electric heating options have their advantages and disadvantages. By carefully considering your camping habits, budget, and personal preferences, you can make an informed decision about which heating method will best suit your RV lifestyle.

Another user on a forum mentions that they purchased a Honeywell HHF360V portable heater rated at 1500 watts for around $30, which helped reduce their electricity usage compared to a furnace. This option is significantly cheaper than the previous one but may not be as powerful for heating an RV in colder climates.

It is important to note that converting an RV propane furnace to electric may require managing power usage to avoid tripping the circuit breaker. This may involve running certain appliances, such as the refrigerator and water heater, on propane while the furnace is running on electric.

Additionally, there may be costs associated with modifying the ductwork, adding breakers, and purchasing the necessary materials, such as wires and heat strips. These costs can add up, especially for older RVs that may require more extensive modifications.

Overall, while there are cost-effective options available, such as the CheapHeat system, the final expense of converting an RV propane furnace to electric will depend on the specific circumstances and requirements of the RV owner.
