Can I put a tankless water heater in my RV – Expert Opinion

Whether you’re a novice or expert, “Can I put a tankless water heater in my RV?” is always a confusing thought. Although RVs are unique, there are some things you can get puzzled about, such as putting an RV water heater. 

An RV tankless water heater is an energy-efficient, central heating equipment that heats water through a gas burner ignited by the unit’s electrical circuit. Whether you’re considering buying a tankless water heater for your RV or replacing your current one, there are some crucial factors to consider when choosing the right one for your camping needs.

This article will discuss the common question: Can I put a tankless water heater in my RV. We will highlight some of the best options for tankless hot water heaters for RVs and explain which one is right for you.

What is a Tankless Water Heater?

A tankless water heater is a type of water heater that does not use tanks. Tankless water heaters use the thermosiphon principle to heat water, which means the hot water circulates around a metal coil inside the unit. 

If you are an RV owner and love camping, you will know the necessity of putting a tankless water heater for the camper. Using a tankless water heater in your RV is portable, eliminates the need for frequent refilling of the water tank, and is environmentally friendly.

How Does a Tankless Water Heater Work?

Water heaters that are tankless work differently from those that are traditional. A tankless water heater circulates heated water around a heating element using a small pump instead of a tank. This means you don’t need to fill up your tank every time! Tankless water heaters are great for RVs because they are compact and easy to install.

What should you consider when selecting an RV tankless water heater?

So, can I put a tankless water heater in my RV? Yes, without any doubt. But be careful in selecting a proper RV water heater. 

The most common and popular are electric RV water heaters. When choosing an RV tankless water heater, you should consider the size of your vehicle and the amount of water you will be using. You must also decide whether you want a permanent installation or a portable unit. 

Types of tankless water heaters

Tankless water heaters are an excellent option for RVs because they are smaller and more efficient than tank water heaters. Water heaters without tanks fall into three categories: gas, electric, and propane. 

Natural gas tankless water heaters produce heat by burning gas, while electric tankless water heaters create heat by using electricity. Propane tankless water heaters use propane to generate heat.

Each type of tankless water heater has its advantages and disadvantages. Gas tankless is the most efficient but most expensive form of water heating. A gas or propane tankless water heater will produce more heat than an electric one, but it won’t be as cheap as an electric one.

If you’re looking for a small, efficient hot water heater for your camper that doesn’t require a lot of space, a gas tankless water heater is a good option. An electric tankless water heater is a good option if you’re on a budget. If you want to produce a lot of hot water quickly, a propane tankless water heater is the best option.
