Buying Guide for the Best Rv Furnaces

Choosing the right RV furnace is crucial for ensuring comfort during your travels, especially in colder climates. An RV furnace is designed to provide heat to your recreational vehicle, making it a cozy and livable space regardless of the weather outside. When selecting an RV furnace, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specs will help you make an informed decision and enjoy a warm and comfortable RV experience.
BTU RatingBTU stands for British Thermal Unit, and it measures the heating capacity of the furnace. This spec is important because it determines how much heat the furnace can produce. Generally, RV furnaces range from 16,000 to 40,000 BTUs. For smaller RVs or moderate climates, a furnace with a lower BTU rating (16,000-20,000) may be sufficient. For larger RVs or colder climates, you might need a higher BTU rating (30,000-40,000). Consider the size of your RV and the typical weather conditions you will encounter to choose the right BTU rating for your needs.
Fuel TypeRV furnaces typically use either propane or diesel as fuel. This spec is important because it affects the furnace's efficiency and compatibility with your RV's existing systems. Propane furnaces are common and widely available, making them a popular choice. Diesel furnaces are more efficient and can be a better option if your RV already uses diesel for other appliances. Consider your RV's current fuel setup and your preferences for fuel efficiency when choosing the fuel type.
Power ConsumptionPower consumption refers to the amount of electricity the furnace uses to operate. This spec is important because it impacts your RV's overall power usage and battery life. RV furnaces typically require 12V DC power for the fan and ignition system. Lower power consumption is better for conserving battery life, especially if you plan to do a lot of boondocking (camping without hookups). Check the power consumption rating and ensure it aligns with your RV's power capabilities and your camping style.
Size and WeightThe size and weight of the furnace are important because they affect the installation process and the available space in your RV. This spec is crucial for ensuring the furnace fits in the designated area without causing any issues. Measure the space where you plan to install the furnace and compare it with the dimensions of the furnace. Also, consider the weight, as heavier units may require additional support. Choose a furnace that fits well in your RV and is easy to install.
Noise LevelNoise level refers to how loud the furnace operates. This spec is important for maintaining a comfortable and peaceful environment inside your RV. Some furnaces can be quite noisy, which can be disruptive, especially at night. Look for furnaces with lower noise levels if you are sensitive to sound or prefer a quieter atmosphere. Manufacturers often provide noise ratings, so compare these to find a furnace that operates quietly.
Thermostat CompatibilityThermostat compatibility indicates whether the furnace can be controlled by a thermostat. This spec is important for maintaining a consistent and comfortable temperature inside your RV. Some furnaces come with built-in thermostats, while others can be connected to an external thermostat. If you prefer precise temperature control, look for a furnace that is compatible with a thermostat. This will allow you to set and maintain your desired temperature easily.
