Best Space Heater for RV

A Space Heater is a small heater optimised for heating small spaces like RVs or mini vans quickly and portability. When considering the best Space Heater, you need to consider things such as its heat output – is it producing more heat than is necessary (therefore using up too many resources), is it not producing enough (therefore not producing the required effect)?

What fuel source it uses or how much electricity it draws is important as well. A typical RV furnace will use from 4 to 14 amps based on its heat production; most RVs will draw from 8 to 9 amps of power. It is also worth considering if it comes with features such as a timer so that you do not draw electricity from a battery to the point that it drains the battery as this will cause damage to the battery. Continuously drawing heat is also a fire hazard because it may put a strain on the wires, your socket, or the heater and cause a fire.

When getting a space heater consider if the place you are heading for can provide you with the required electricity and at what cost. Using a high heat output space heater might be okay if you are next to a campsite or house where it is easy to connect the heater with a safe, reliable power source.

What You Should Know Before Buying space heaters for RV

Heater size & efficiency

The more efficient a heater is, the lower the cost to power it will be. Larger heaters are not always better; they consume more wattage and require larger power sources. This is especially bad when you do not have access to high voltage power supplies such as mains from a house or campsite.

Smaller heaters sometimes can be more effective than their larger counterparts. If you live in an area where your home gets very cold during the winter months, you’ll need something that provides quick bursts of hot air – small space heaters are good for this purpose. It may even be worthwhile purchasing two of them rather than one large unit so that you don’t have to wait long periods without heating if one breaks down or runs out and so that you can place them strategically, in this way you’re always near a heat source.

Some heaters are more efficient than others as they re-circulate cabin air as opposed to using cold air from outside. This means that the warm air stays warm instead of everywhere being cold.

Sometimes you only want the heating to be on for as long as it takes you to fall asleep. In this way, a larger heater might be a better option as you can heat more air before you must refuel the heater as larger heaters often have larger fuel compartments.

Various RV Heaters

There are 3 types of RV heaters – convection heater, radiant-style or even steam RV heaters that generates steam from boiling water to create hot air. In the recent years, you would find a lot of heaters also connected to solar panels to make it more fuel efficient.

Maintenance & warranty

Taking good care of your heater will also help you avoid worn-out parts. You’ll want to make sure it’s clean and free of dust or debris that could catch fire if the heater is ever accidentally turned on. It’s also important to remember not to block any vents because doing so can cause your appliance to overheat, which in turn could lead to a fire.

Questions and Answers About space heaters for RV

What size heater do I need for my RV?

When heating uup your RV, you need to consider if you are attempting to heat the entire space of your RV or if you are attempting a more targeted heating by trying to warm up your body or your sleeping or working area.
If you are trying to heat up the entire space, you need to decide how much heat your heater has the capacity to produce, which also determines the size of the heater you buy.
Heat production is measured in BTUs (British Thermal Unit). The higher the BTUs something produces the greater its heating power. A room’s BTU requirement is dependant on the cubic volume of space. To calculate the BTUs per square foot you take the square footage and multiply it by 20 BTUs for a warm climate and 50 BTUs for a cold climate.
Class A motorhomes are the biggest and can have lengths from 21 feet to 45 feet, 33 feet on average, widths of 9.5 feet on average. This means they could be anything from 199.5 square feet to 427.5 square feet and on average 313.5 square feet. This would mean a BTU requirement of 3,990 to 8,550 (average 6, 310) BTU in a warm climate and 9,975 to 21,375 (average 15,675) BTU in a cold climate.
Class C motorhomes are between 20 – 33 feet, on average 28 feet, in length and are 9 feet in width. This means a volume of 180 to 297 (average 252) square feet. This would mean a BTU requirement of 3,600 to 5,940 (average 5, 040) BTU in a warm climate and 9,000 to 14,850 (average 12,600) BTU in a cold climate.

Can I run my RV heater all night?

This is a common question. It depends on the particular model and it’s ok in many cases but running your RV heater all night will risk your battery going completely flat, which will make it hard for you to start the vehicle. If you need to run the heater for more than an hour or two at night, plug the cable into an outlet with a timer on it so that it will turn off before your car needs to restart in the morning.
The best alternative is just to sleep with clothes on and use hot water bottles if it’s really cold.

Is it cheaper to run a space heater or electric heat?

‘Space heater’ refers to the reach of the heater – covering from a small to medium-sized area. As opposed to the larger, more comprehensive, central heating which is sometimes referred to as ‘electric heating’. Having an electric heat system might also lead to better management of electricity, leading to you saving money over time. An electric heat system does, however, require that you put in an electric system which is a significant upfront cost. A space heater is less likely to need lots of power and more likely to be able to work with your current electricity supply. As it is likely that you won’t need to install a new electrical system to power a space heater there is less upfront cost in installing an electric space heater. A space heater is generally smaller than an electric (central) heater in size and therefore often cheaper. Space heaters do not have to heat as large of an area, so the running cost is likely to be less for a space heater.

How do you heat an RV in the winter?

Using solely electricity to power your heater is often difficult if not impossible in the winter without a direct mains electricity supply or campsite electricity. The demand in the winter is too much and the generation is too little. Things like solar panels may have been a solution in the summer but cannot generate enough electricity in the winter. Solar panels work in the cold, in fact, they are even slightly more efficient in the cold. Light reflected from the snow can help the solar panels reach high levels of efficiency. However, the fact that the days are shorter in winter means that solar panels will still generate less electricity in the winter than in the summer.
For these reasons heating solutions that require minimal electricity are the best solutions for the winter. Propane is best stored in well-ventilated, cool places. In this way, it is okay to store propane in a locker where it might become very cold because of winter temperatures. The condensation point of Propane is -42 degrees Celsius. It is improbable that you will be venturing anywhere that will reach that threshold and probably not in an RV. Propane is a popular method of heating for RV users and there are lots of choices so that you can select a heater that offers the functionality, safety, and heating potential that you need.

Do you need electricity to run RV heater?

Electricity is a popular source of power for RV heaters since electricity it is considered a greener, environmentally friendly source of energy (as well as relatively safe and familiar). There are different electric space heaters that rely solely on electricity to power them, these include ceramic, fan, infrared, oil-filled, and panel space heaters.
Even gas furnaces that are fuelled by gas need some degree of electricity for it to run. Often heaters use fans to distribute hot air around the room and will use fans to push exhaust gases through a flue. Additionally, gas furnaces often use circuits boards and sensors. Without the necessary components to guarantee safety such as Carbon Monoxide detectors, oxygen detectors, or Liquid Propane (LP) gas detectors most gas furnaces simply won’t run.
You can find some gas heaters that do not require electricity to run. When buying a gas heater for your RV it is important to double-check whether the heater uses a small amount of electricity or not. If it doesn’t it is important to buy your own battery-powered safety detectors.
