RV Water Heater FAQ

After reading our reviews of the best RV water heaters on the market, you’ve seen that some of them are tankless. Are these beneficial for RVs?

Let’s answer that question as well as others you might have when shopping for RV water heaters.

Are tankless water heaters good for RV?

Are tankless water heaters good for RV?

Tankless water heaters give you instant hot water without you having to worry about them requiring storage in the form of a tank, which makes them practical for RVs. These water heaters have other benefits.

  • They are more energy-efficient than regular tank heaters. They are less likely to lose heat than heaters that store water in a tank for later use. You will use the hot water you need without wasting any of it.
  • They distribute water effectively. If you’re RVing with a large family, you’ll experience times when more than one person requires water at the same time, such as if one person wants to use the shower while someone else is doing the dishes, so you’ll benefit from having instant hot water without having to wait for it to heat up.
  • They save you on propane costs. Using a tankless water heater enables you to use less propane because of how it doesn’t store water at a set temperature. 
  • They help you save money in general. You want to save money when you’re using your RV, and you can do that with a tankless water heater system. This heater saves energy while also preventing you from having to run cold water while you wait for it to heat up, which will ensure you stay within your budget.  

What are the two types of RV water heaters

There are two main types of RV water heaters. These are gas and electric water heaters.

Electric water heaters require your RV to be running in order for the heat to work, whereas gas water heaters use heat from the RV’s engine or run on a gas-powered pilot light.

Gas water heaters are great for you if you go camping in remote areas where you don’t have access to power or water. The drawbacks of a gas water heater are that their internal components require a 12-volt power source in order to work and when the gas runs out you won’t have hot water. 

By comparison, electric water heaters are ideal if you want the convenience of not having to buy propane when you’re on the road. You can also use the camping site’s shore power.

Electric water heaters are effective at maintaining the water temperature you want and since the heating element cycles on and off as you require water, you won’t have to turn off the heater when it’s not being used.

That said, if you want to camp in an area where you can’t get shore power, you might battle to source electric power.

Can I put a bigger hot water heater in my camper?

Can I put a bigger hot water heater in my camper?

Generally, water heaters for campers come with a capacity of between six to 10 gallons, but you can find smaller ones as well as larger ones that have a capacity of up to 16 gallons. 

If your camper has enough space for a larger water heater, you can go ahead and install it. This will give you more hot water to meet your requirements. A larger tankless water heater is ideal as it will put less stress on the system and be more energy-efficient to run.

Before you replace your current water heater for a larger one, make sure you check and double-check the size of the opening where you wish to install it, making a note of the height, depth, and width required.

Can I leave my RV hot water heater on all the time?

It might seem convenient to leave your hot water heater on all the time, but this is not always recommended. It really depends on the type of water heater you have.

If you have a gas water heater, you should turn it off when traveling on the road. This is because the movement of the RV could put a strain on the lines connecting your propane tank to your appliances, which can cause them to break and release gas over time.

This can be dangerous, such as by causing an explosion or being a health risk.

If you own an electric water heater, you can safely keep it on all the time. However, you need to consider that you will experience higher costs when doing this than if you only put it on when you require hot water.

By staying at a campground where you can make use of shore power, you can reduce your electricity expenses, so that’s something to consider before you hit the road.
