Best RV Tankless Water Heater Reviews

Even when you are living in an RV, you still would want to pursue things that can help bring more comfort to your on-the-go lifestyle. With that said, having a water heating device in your mobile home can be a good addition. But instead of those traditional water heaters that make use of a tank, consider the benefits of a tankless water heater. It can make a world of difference as to your comfort and how water is delivered to your RV.

There are a lot of tankless water heaters out there but for RV needs, make sure you are choosing the right one suitable for a smaller space. We checked out what the market has to offer and found those that offer energy efficiency, space-saving benefits, ease-of-installation, good water heating capacity and durability. Read on to discover the best RV tankless water heaters you can rely on today.

What Should You Choose a Tankless Water Heater for your RV?

There are standard tank water heaters for RV use but why should you choose for the tankless ones? The problem with most standard RV water heater is that they have a limited capacity of 6 to 10 gallons. Sure, that should be enough for a small family who will just be using this camper van for a day or two but if you are going on a week-long vacation outdoors or road tripping for weeks, that isn’t sufficient for your needs. The last thing you would want is for your hot water supply to be cut off in the middle of rinsing off shampoo from your hair.

The good thing about the tankless water heater is that it heats up water on demand. As long as you have fresh supply of water, you can have fresh supply of hot water as well. It is also more efficient to run as it only heats up water when you need it, so the machine isn’t working all the time to keep stock water hot. Because of this, it is less costly to run, and it is better for the environment. There are also fewer risks of fires as there is a lesser chance of overheating.

Another reasons to get a tankless water heater for your RV is its space-saving benefit. It doesn’t take up a lot of space unlike traditional RV water heaters that still make use of a tank.

What Should You Look For?

Temperature and climate of the places you go to.

Some tankless water heaters might freeze up in lower temperature so if you are going to a higher location with more freezing weather, go for those that are more durable and have more power.

Safety features

Make sure you ensure that the water heater will not cause harmful gas to accumulate indoors. If it is electric, go for those that also include safety features such as child lock.
