The 8 Best RV Heaters: The In-Depth Reviews in 2023

RVs are designed to be comfortable for extended periods, but it can be tough living there when the temperature drops. When you do full-time RVing, it will be suicidal not to have a heating system in place during winter. And only the best RV heater can keep you warm and toasty on chilly nights. 

Not all heaters are suited for every RV or winter everywhere. Electric heaters could be the best choice for indoor use, but a heavy-duty propane heater is the most suitable for sub-zero temperatures and an outdoor place. 

We’ve reviewed some of the best camper heater options so you can find a suitable one within your budget and requirements. 

What is an RV Heater?

An RV heater is a device designed to heat the interior of a recreational vehicle (RV). It is an essential component for RVs that are used in colder climates or during the winter months. The purpose of an RV heater is to provide a source of heat inside the RV, making it a more comfortable living space.

There are two main types of RV heaters: propane and electric. Propane heaters burn propane gas to produce heat, while electric heaters convert electrical energy into heat. Both types of RV heaters work by circulating warm air throughout the RV using a blower or fan.

RV heaters come in a range of sizes and capacities to suit different types of RVs. They are typically designed to be compact and efficient to conserve space and power consumption.

Additionally, many RV heaters come equipped with safety features such as automatic shut-off switches and carbon monoxide detectors to ensure safe operation. Overall, an RV heater is an important component for ensuring a comfortable and safe living space inside an RV.

What are the Different Types of RV Heaters?

To find the best RV heater, it’s necessary to have a clear idea about all available options. Otherwise, you may pick up a good product only to discover that it’s completely unsuitable for your needs. 

Depending on the power source, these products can be of two types: electric RV heaters and propane RV heaters. 

A propane-run unit could be the best heater for RV boondocking since it doesn’t need electricity. They are cheaper than other options and good for extremely cold temperatures. Their biggest problem is they can be a safety hazard if you are not careful. 

An electric heater for RV is the most efficient and requires the least maintenance. They are not the most budget-friendly but safer than RV propane heaters. They are not suitable for off-grid camping or in areas where there is no access to electricity.

Again, there are three different variations of electric heaters:

• Infrared/Radiant 
• Ceramic 
• Oil-filled

A ceramic heater is popular as it can distribute heat faster than other types, but the warmth fades away quickly when the heater is off.

On the other hand, radiant oil-filled and infrared heaters take more time to warm up a space, but the heat lasts for some time.

So, there are several different types of RV heaters available, each with their own set of benefits and drawbacks. When choosing a heater for your RV, it’s important to consider your specific needs and the conditions you’ll be camping in. Additionally, it’s important to choose a heater that is safe and efficient to ensure a comfortable and enjoyable camping experience.

How Does an RV Heater Work?

Propane RV heaters

Propane RV heaters are a popular choice for recreational vehicles because they are efficient and reliable.

They work by burning propane gas to produce heat, which is then circulated throughout the RV using a blower or fan. Here’s a closer look at how a propane RV heater works:

• Ignition: To start the propane RV heater, you first need to ignite the propane gas. This is typically done using a pilot light or an electronic ignition system. Once the propane is ignited, it begins to burn and produce heat.
• Combustion: The burning propane produces heat through a process called combustion. Combustion occurs when a fuel, in this case, propane, reacts with oxygen to produce heat, water vapor, and carbon dioxide.
• Heat exchanger: The heat produced by the burning propane is then transferred to a heat exchanger. The heat exchanger is a metal component that is designed to absorb the heat from the combustion process and transfer it to the air that will be circulated throughout the RV.
• Blower or Fan: Once the heat has been transferred to the heat exchanger, it is then circulated throughout the RV using a blower or fan. The blower or fan is typically located in the heater unit and is designed to distribute the warm air evenly throughout the RV.
• Thermostat: A thermostat is used to control the temperature inside the RV. It is connected to the propane RV heater and is used to turn the heater on and off as needed to maintain a comfortable temperature.
• Exhaust: Propane RV heaters produce exhaust, which must be vented outside of the RV. This is typically done using a flue or chimney, which is connected to the heater unit and extends through the roof of the RV.
• Safety features: Propane RV heaters are equipped with several safety features to ensure safe operation. These may include automatic shut-off switches, carbon monoxide detectors, and flame sensors. These safety features help to prevent accidents and ensure that the heater operates safely.

In short, propane RV heaters work by burning propane gas to produce heat, which is then transferred to the air using a heat exchanger and circulated throughout the RV using a blower or fan.

They are an efficient and reliable option for heating an RV, but it’s important to follow the manufacturer’s instructions for safe operation and maintenance to ensure that the heater operates safely and effectively.

Electric RV heaters

Electric RV heaters are a popular choice for RV owners because they are easy to use and don’t require any fuel storage or ventilation.

They work by converting electrical energy into heat, which is then circulated throughout the RV using a blower or fan. Here’s a closer look at how an electric RV heater works:

• Heating element: The heating element is the key component of an electric RV heater. It is typically made of metal and is designed to resist the flow of electrical current, which causes it to become hot. The heating element is located in the heater unit and is designed to absorb the electrical energy and convert it into heat.
• Blower or Fan: Once the heat has been produced by the heating element, it is then circulated throughout the RV using a blower or fan. The blower or fan is typically located in the heater unit and is designed to distribute the warm air evenly throughout the RV.
• Thermostat: A thermostat is used to control the temperature inside the RV. It is connected to the electric RV heater and is used to turn the heater on and off as needed to maintain a comfortable temperature.
• Safety features: Electric RV heaters are equipped with several safety features to ensure safe operation. These may include automatic shut-off switches and overheat protection. These safety features help to prevent accidents and ensure that the heater operates safely.

There are a few different types of electric RV heaters, including:

1. Ceramic heaters: Ceramic heaters use a ceramic heating element to produce heat. They are popular because they are efficient and produce a lot of heat for their size. Additionally, they are relatively safe and don’t produce any emissions or fumes.
2. Radiant heaters: Radiant heaters produce heat by radiating infrared heat waves. They are popular because they are efficient and produce a lot of heat, but they can be expensive to operate and may not be a good choice for RVs with limited electrical capacity.
3. Oil-filled heaters: Oil-filled heaters use electricity to heat up a reservoir of oil, which then radiates heat into the surrounding air. They are popular because they are efficient and produce a lot of heat, but they can be slow to warm up and may not be a good choice for RVs that need quick heating.

In the other words, electric RV heaters work by converting electrical energy into heat, which is then circulated throughout the RV using a blower or fan.

They are an easy-to-use and efficient option for heating an RV, but it’s important to follow the manufacturer’s instructions for safe operation and maintenance to ensure that the heater operates safely and effectively.

What to Consider When Buying a New Camper Heater?

When buying a new camper heater, there are several important factors to consider to ensure that you choose the right one for your needs. Here are some key things to keep in mind:

1. Fuel Source: The first decision to make is whether you want a propane or electric heater. Propane heaters are ideal for boondocking or off-grid camping, as they do not require electricity. Electric heaters, on the other hand, are better for RV parks or campsites with electrical hookups.
2. Size and Capacity: Consider the size of your RV and the number of people who will be using it. You want to choose a heater that is powerful enough to heat the entire space, but not so large that it wastes energy.
3. Efficiency: Look for a heater with a high energy efficiency rating. This will help you conserve fuel or electricity and save money on heating costs.
4. Noise level: Some heaters can be quite loud, which can be disruptive when you’re trying to sleep or relax. Look for a heater with a low decibel rating.
5. Safety features: Safety is always a top priority, so look for a heater with built-in safety features such as automatic shut-off switches and carbon monoxide detectors.
6. Installation: Consider the ease of installation. Some heaters require professional installation, while others can be easily installed by the owner.
7. Brand: Look for heaters from reputable brands with a history of producing high-quality, reliable products.
8. Price: Finally, consider the price. Camper heaters can range in price from less than $100 to several hundred dollars. Look for a heater that fits your budget, but don’t sacrifice quality for cost.

Overall, choosing the right camper heater comes down to balancing your specific needs and preferences with the available options on the market.

Take your time to research different models, read reviews, and ask for recommendations from other RVers to find the perfect heater for your camper.

Conclusion

Choosing the best RV heater depends on your needs. For example, if you travel to high places often, you can’t use most propane heaters since they can’t work where oxygen is low.

Again, an indoor heater won’t be the best option for you if you spend more time outside. So, first, decide on what you really want and then get that heater for yourself. 

If you want a performer at a reasonable price, we recommend the Lasko oscillating ceramic space heater.
