Types Of Electric Caravan Heaters

There are several types of low voltage heaters you can use to warm your caravan, including:

Portable Fan Heater

These are the commonly the smallest and lightest heaters and are great if you need to warm up a room as quickly as possible. They’re simple to set up and get going because all you need to do is remove it from the box, plug it in and press the on button.

The main issue with portable fan heaters is they can be loud, which may make it difficult to run if you’re trying to sleep as it can disturb you.

Convector Portable Heater

Convector heaters have a similar specification to portable heaters because of their small and light in construction. This makes them ideal for transporting, especially for caravan usage as it won’t add much weight to your existing load.

This type of heater warms up quickly but is significantly quieter than portable fan heaters which makes it great for caravan use. Because portable convector heaters are light, it also means that they can be mounted onto the wall in order to save space.

Oil Filled Electric Heater

Oil-filled electric heaters cost less to run, but they heat up at a much slower rate when they’re switched on. So if it suddenly gets cold, then you’ll need to wait longer for your caravan to heat up.

Oil-filled heaters are also much heavier than the other two types of the heater, but they usually come equipped with wheels, which means it can be easily transported.

When it comes to noise, oil-filled heaters are almost silent, which is great if you’re using it when you’re trying to sleep or any other activity where you want to avoid disturbances.

Oil-filled heaters are also safe to use as they come pre-sealed so there isn’t the threat of oil leaks. Modern oil-filled heaters don’t require oil to be changed because there is no oil burning taking place. 

What To Look For In Caravan Heaters

There are several features and factors that you need to understand before you can make a final caravan heater buying decision.

Price and Running Costs

When deciding on a heater, you shouldn’t only consider the initial price from the retailer but also the running costs. Heaters will vary in their levels of energy consumption so you should be aware of this before purchasing. 

Many low wattage heaters will be eco-friendly consuming fewer levels of energy which is especially important when using it in a caravan where electricity will be more limited.

In terms of running costs, Oil-filled heaters will take longer to warm themselves up, but once you switch it off, it still gives off heat as it cools down. Whereas convector heaters can warm up your caravan quickly, but as soon as you switch it off, it stops giving off any heat. So depending on how you use them, this will affect your electricity usage in different ways.

If you’re just looking to dry a few clothes or provide a blast of heat in a small space, a heated towel rail can be a good budget alternative.

Safety Features

The best caravan electric heaters will have a thermostatic valve that automatically turns off once it reaches your selected temperature, plus this also stops your caravan from overheating.

An auto shut-off feature means that you don’t need to keep remembering to turn it off manually each day.

Another great feature is tip-over protection which means if for whatever reason your heater falls over, then it automatically turns off. These are three small features that make heaters much safer, there are many more, so it’s essential to check before purchasing.


In a caravan, you need appliances that are light and compact, so the weight of your heater is important especially if you plan to move it around the caravan once it’s inside such as storing it away when it’s not in use.

Modern technology has advanced at a fast rate, so most heaters are light and easy to carry, but you should still check the weight before purchasing.


Portability and weight correlate; however, a heavy heater can still be easy to move if it has additional features.

These features could be in the form of wheels or handle because you don’t want there to struggle each time you want to move it. This isn’t as much of an issue if you plan to keep it in the same position inside your caravan forever.


Portable and convector heaters aren’t usually the most stylish of products; however oil-filled heaters come in a range of styles and finishes.

Although most people won’t mind what it looks like as long as it gets the job done if you are style conscious, then you’ll be able to buy one that matches the style of you caravan interior.


Caravans are often compact spaces so you need to consider the power output of your heater as this determines the size of the room that it can heat.

If your heater output is too high, then you can end up just wasting power, especially if you’re using it in a smaller sized room. The best caravan electric heaters will have an adjustable power setting that you can tailor to your needs.


The noise levels generated by your chosen heater is essential if you’re going to be using it when you need peace. It’s counterintuitive to solving the issue of being cold at night if you still can’t sleep because of the noise being made.

Generally, oil-filled heaters are very quiet whereas convector heater also makes little noise. If you need silence, then portable fan heaters are the ones to avoid.

Timer Setting

Premium electric heaters will have an inbuilt timer function which will give you the option to heat your caravan for a specific period then the heater will automatically switch itself off. Usually, the timer comes inbuilt however you can also buy the timer separately and attach it to the heater, but this varies by the heater model.


Some heaters have a dual capability of also being able to cool a room. Of course, their cooling ability is usually not as effective as a dedicated fan or air conditioner, but this is often better than nothing and also means you can avoid having both a fan and heater where space is at a premium in a caravan.


Just like any electrical product, its components can develop a fault at any time, so you must understand the protection that comes with the heater which usually comes in the form of a warranty.

A strong warranty will protect you against any faults that develop entitling you to a repair or replacement, giving you the added security. Warranty lengths can vary but are generally 1-3 years.
