10 Best Rv Furnaces 2026 in the United States

The Empire Comfort Systems Direct-Vent Wall Furnace offers a solid heating solution with a 35,000 BTU rating, making it suitable for heating medium to larger indoor spaces. It runs on liquid propane or natural gas, which is common and convenient for many RV owners who have access to these fuel types. The direct-vent design improves safety by venting combustion gases outside, ensuring cleaner indoor air.

The unit is relatively compact (about 37" wide and 28" high) and mounts on the wall, which helps save floor space—important in RVs where space is tight. The heat output is fairly strong, making this model a straightforward, gas-powered furnace that fits a wall mount and provides steady heat without advanced technology.

This furnace does not include smart home compatibility, so remote control or advanced temperature programming features are not available. It is a good choice if you want a dependable heating unit without additional smart features or noise level considerations.

The Suburban RP-35FQ Replacement Core is designed to offer a solid heating solution for RVs, particularly for those who already own compatible Suburban furnace models. With a BTU rating of 35,000, it's well-suited for heating larger RV spaces efficiently. This unit is made from high-quality materials, ensuring durability and reliability during your travels.

One of the key strengths of this furnace core is its compatibility with various Suburban furnace models, making it a versatile option for many. Its size and weight (20 x 12 x 7.5 inches and just 1 pound) also make it manageable for installation and maintenance. Additionally, the unit is relatively quiet during operation, which is a significant plus for those who prefer a peaceful environment while camping.

However, there are some considerations to keep in mind. While it boasts impressive heating capacity, potential users should verify compatibility with their existing systems, as it's specifically designed for certain Suburban models. The product's performance can also vary based on the insulation of your RV and outside temperatures, so those in extremely cold climates may need to assess if this unit meets all their heating needs. Lastly, while it appears to be designed for everyday use, installation complexity could be a factor for less experienced DIYers.

The Suburban RP-30FQ is a 30,000 BTU/h replacement core designed specifically for Suburban furnace models like the SF-25F and SF-30FQ. If you need a cost-effective solution to replace an old furnace, this product provides a seamless and budget-friendly option. It fits comfortably into your existing furnace cabinet, saving you time and the hassle of extensive installation work. The compact design of 20 x 17 x 7.5 inches maximizes space within your RV, making it a practical choice for smaller areas.

One of the standout features is its ease of installation, allowing you to slide the module into place without needing professional help. This is particularly advantageous for RV owners who appreciate DIY solutions. Additionally, the two-year limited warranty offers some reassurance regarding its reliability and quality.

While the RP-30FQ is an affordable alternative, it is designed exclusively for certain Suburban models, which may limit its appeal if you own a different type of furnace. It is important to ensure that your existing system is compatible and to consider potential downsides such as noise and the specifics of power consumption that might affect your decision.
