A Few Things That Should Complete Your Research

When it comes to picking the ideal heater for your RV, you’ll have to go over several factors that will tell the proper options from the bad ones. This will help you pick the right product according to quality and your needs. Here’s what you need to know:

Types of Heaters

There are several types of electric heaters out there, so it’s important which one is which before choosing:

Fan Heater

Exactly like its name says, a fan heater is an appliance that works like any other fan but this time blowing hot air. However, fan heaters are often really hot and provide great performance, so they are very useful for trailers.

Convection & Panel

These are the conventional type of heater. It uses an electric heating element to warm up the air and then raise it over the ceiling or exhale it through a grille. These options are normally the most powerful, but often the ones with the most electric consumption and the hardest to install.

Ceramic Fan

A ceramic fan is exactly like a fan heater but with ceramic heating elements. This means it heats up faster and provides great performance while reducing dangers. These heaters also tend to work way cooler than standard fan heaters.

Radiant & Infrared Heater

These heaters don’t use a fan or convection system. Instead, they use a heating element to provide infrared heating capacity. The system may vary depending on the model and design, but most of the time they use less energy & give faster results than other options.


This is the traditional heater most people use. The oil is not needed to create the heat but to transfer it to the place where it is working. Instead, it uses electricity to heat up this oil and transport it through the columns or fins. There are many different types though, so you may encounter some that don’t use oil but look similar.

Heating Capacity

There’s no point on getting a product if you don’t know how good it is, and for electric heaters – heating capacity is maybe the most critical factor to consider.

Here we recommend looking for two important measures: watts and BTUs. While some heaters offer only one of these, others may provide both so you can have a better idea of how effective it is. But this also means that watts are different from BTUs.

The measure of watts is to know how much heating power the device offers. With more watts, the more potential the heater has. Most heaters for RVs come with a 1,500 watts capacity, which means it can heat up any trailer or RV without issues.

Then you have BTUs; this is the measure for British Thermal Units. It tells you the amount of space but also the heating potency of the product.

The more BTUs the product has, the more heating capacity you will receive. Anything over 5,000 BTU will be enough. If it goes over 8,000 BTU, it will probably heat up too much and too fast, but still decent for a trailer.

Safety Features

Remember that you’re going to use the appliance on an RV, so it is critical to pick something that’s safe and reliable.

For this, there’s nothing better than to go for a heater with automatic shut-off, overheating protection, cool-down body, and a reliable heating system. Anything that heats up by creating a fire or without any regulating feature is something you need to get away from.

Convenience & Portability

The weight, the design, the length of the power cord, the handle, and even wheels if possible. When an electric heater comes with functions that add convenience & portability, it is probably a better option than any other that doesn’t. The more portability features the product offers, the better it will be for sure.


While it is important to get the right portability for an RV and excellent performance, it is also a great idea to pick something with the ideal controls & operation system.

We recommend going for heaters with remote controls if possible, with a thermostat so you can adjust the temperature to your needs, and dials for settings. A timer is also a useful control feature to have.

Frequently Asked Questions

Many users have doubts before buying, which can eventually harm their choice and possibly disappoint them. To relieve any doubt you can have, here are common questions most users have before choosing:

Will an RV electric heater be sufficient for my trailer?

A: It actually depends on the size of your trailer and the capacity of the heater. But most of the time, a 5,200 BTU electric heater at 1,500 watts will be more than enough to warm up your RV.

Should I follow any steps to prevent possible accidents?

A: We recommended leaving an area of three feet around the heater at all times, taking special care to remove flammable or combustible items. Most heaters can operate automatically.

But it’s never wise to leave them unattended (while sleeping or out of the trailer). Never use extension cords and make sure the heater is installed in a stable and sturdy place.

How long does an electric heater for RV last?

A: An electric heater lifespan depends on the design and model, but most of them last between 5 and 25 years. The smallest and most portable options can last 10 years with the right use, and the largest ones last up to 25 years without problems.

What should I do if I smell burning?

A: Smelling of burn with an RV electric heater is common. It’s not necessarily a bad thing, as most heaters tend to have this smell due to interior dust or debris, sometimes coming from the box. But with a regularly-used heater, any strong smell of burning with deficient performance should be of concern. Call an expert immediately.

What can I do if my electric heater is not as hot as I expected?

A: Most electric heaters are less hot than gas heaters or other alternatives, so it’s common for previous owners of gas heaters to feel like their new RV electric appliance is not working correctly. However, electric heaters actually work well even when they are less hot; they just distribute the heat more effectively.

Final Words

When it comes to picking the ideal electric heater for your trailer, you will have to consider everything, from the size of your trailer to the type of appliance you want or need, as well as many other things.

While this process can be frustrating and challenging, it’s the only way to get the best RV electric heater, so you can eventually have a great experience. Follow our advice, and you will not be disappointed!
