How Long Can an RV Heater Run on Battery?

RVs can get cold, especially in the winter, and nothing is worse than being cold while traveling. Colder climates mean your RV needs to be heated properly. One way to do this is by using an RV heater.

But how long can an RV heater run on battery? This is a question that a lot of RVers ask. An RV heater can run on a battery for about 12.5 hours, according to most expert advice.

However, there are a few things you can do to increase the battery life of your RV heater. In this blog post, we will provide tips on keeping your camper warm and comfortable all winter long.

How Long Can An RV Heater Run on Battery without any Problems?

This depends on the type of RV heater and the power available in the battery you’re using. Electric heaters can run off 12-volt or 24-volt systems, while propane heaters require a propane tank.

It’s important to make sure you have enough power available to run your heater before you leave on your trip. You can use a portable battery pack or an auxiliary battery to provide power to your RV heater.

When using an RV heater, we recommend using a battery with at least  100 amp-hours of capacity. If you have 2 100v amp hour batteries, you’ll have 200 amp hours of usable power. This will give you enough power to run your heater for up to 12.50 hours.

However, if you’re only using one battery, the number of hours your rv heater can run on the battery is reduced by 50%. So, with a single 100 amp hour battery, you’ll have a usable capacity of 50 amp hours, which will only run your rv heater for about six hours.

You can also use an RV surge protector to help protect your batteries from being drained too low. To keep your camper warm, we recommend running your furnace for 20 minutes every hour.

Tips to Extend Batteries Life and Keep Your Camper Warm

Every RVer wants to extend their battery life as long as possible. Here are a few tips to help you do that:

RV is properly insulated
  • Make sure your RV is properly insulated. You can use insulation panels to help keep the heat in.
  • Use thermal curtains to help insulate the windows.
  • Close the vents in your RV when you’re not using them. This will help keep the heat in and conserve power.
  • Use a battery charger to maintain your batteries at full charge. This will help keep them healthy and extend their life.
  • Set the thermostat to a comfortable temperature and not too high or low.
  • Turn off your heater when you’re not in the RV.
  • Monitor your battery level and charge it regularly. You don’t want to run out of power while on vacation.
  • You should purchase higher amp hour batteries. This will give you more power to run your RV heater and other appliances.
  • Place your RV in direct sunlight to help warm it up.
  • You can use a solar panel to help power your RV heater and other appliances.

Types of RV heaters

One of the best ways to keep your RV warm is using an RV heater. There are a few different types of RV heaters available, including propane heaters, electric heaters, and catalytic heaters. If you’re traveling in colder climates, we recommend using a propane or electric heater.

Catalytic heaters are not as effective in colder weather and should only be used in warmer climates

Types of RV heaters

When using an RV heater, it’s important to make sure you’re following the manufacturer’s instructions. Each RV heater is different and has its own set of instructions. If you’re not sure how to use your RV heater, consult the owner’s manual or contact the manufacturer. Here we discuss details on each of them:

Propane RV Heaters:

These heaters work by burning propane gas. They are the most common type of RV heater and are available in both portable and built-in models. Propane RV heaters are relatively inexpensive, easy to use and provide a lot of heat.

Propane RV Heaters

Propane heaters can’t heat any of the plumbing in your RV, so if you’re using one of these heaters, you’ll need to have a heated water hose to prevent your pipes from freezing.

Electric RV Heaters:

Electric RV heaters are the most popular type of heater used in RVs. They come in both portable and built-in models and use either 120-volt or 240-volt power. Electric RV heaters are a great option for those who want to avoid using propane.

They are very safe to use and easy to operate. Electric RV heaters work by using electricity to create heat. This heat is then circulated throughout the RV. Most electric RV heaters come with a built-in thermostat, which allows you to control the temperature in your camper.

Electric RV Heaters

You can place an electric heater anywhere in your RV, but we recommend placing it near the floor. This will help to distribute the heat evenly throughout your camper.

Electric RV heaters can be expensive to run, especially if you’re using a heater with a high wattage. It’s important to make sure you have enough power available to run your heater before you leave on your trip.

Catalytic Heaters:

Catalytic heaters are a type of electric heater that works by using a catalytic converter to convert the propane into heat. These heaters are available in both portable and built-in models.

Catalytic heaters are a great option for those who want to avoid using electric heaters, as they do not require any electricity to operate. They also consume propane at a slower rate than other types of RV heaters.

Catalytic Heaters

One of the features of catalytic heaters is that they don’t resist airflow. Catalytic heaters are available in two different types: portable and built-in.

When using a catalytic heater, follow the manufacturer’s instructions. Each catalytic heater is different and has its own set of instructions. If you’re not sure how to use your catalytic heater, consult the owner’s manual or contact the manufacturer.

FAQs:

Q: How Long can a Deep Cycle Battery Run a Heater?

A deep cycle battery can run a heater for around 3 hours. If you’re using a high-wattage heater, you may need two or more batteries to provide enough power.

Q: How Much Power does an RV Heater Use?

It all depends on how long you use it. The longer you keep the heater on, the more it will use. The most accurate answer is around 37 to 150 W/hrs. Small travel trailers use less power, while larger fifth wheel trailers use more.

Q: How Long Will a 12 Volt Battery Run a 500 Watt Heater?

A 12 volt 100 ah rv battery can run up to 25 hours. A 12 volt battery should be able to run a 500 watt heater for around 10 hours. You need to divide 500 by 120 (Volts in a 12 volt battery) to get the number of amps the heater will draw. This means that the battery can theoretically provide up to 500/120= 4.1 (four and a half amps for ten hours).

Q: How Many Watt Hours does a 100 Amp Hour Battery Have?

A 100 amp hour battery has 1200 watt hours. Using the equation Watts = Amps x Volts, we can see that a 100 amp hour battery at 12 volts would have a watt hour rating of 1200 watts.

Q: How Much Propane does an RV Heater Use?

An RV heater will use about 1/3 gallon of propane per hour. If you have a 20-pound tank, it will last about a week. If you have a 30-pound tank, it may last about two weeks.
