How to Transition to an Electric Tankless Water Heater

If you are ready to transition your existing propane tank water heater to an electric tankless water heater, there are a few more considerations for you to be aware of.

Electricity Usage

It is important to consider your electricity usage before transitioning to an electric tankless water heater. Some units consume less electricity than others and the lower consumption will be appreciated when it comes to RVing.

That said, most electric tankless water heaters only use electricity when you need hot water, which means that you likely won’t have to budget for it while you are not showering or washing dishes. If you have a 50 amp RV, you likely won’t have to worry about your electricity usage unless you are in need of a lot of hot water as well as two air conditioning units, a microwave, and a hairdryer, all at the same time!

Propane Usage

When it comes to buying a new refrigerator, the biggest factor you’ll have to consider is whether you’re looking for one with an ice maker. If so, you’ll want to make sure it has at least a 12-cubic-foot capacity and is able to accommodate a 3.

With an electric tankless water heater you’ll be able to get hot water fast, which can be very convenient in the morning when you’re waking up. Additionally, having propane for cooking and heating is very useful, so an RV propane grill makes sense.

Old Water Heater

Remove your old water heater before you start any new plumbing in your RV. An older, inefficient, electric water heater is likely the biggest reason for you needing new plumbing in your RV. This older, inefficient, electric water heater may even take up room in your RV where you might want it.

You may be able to remove everything from an RV with the right tools, but it can be a bit of a chore. You’ll want to make sure that every fuel hookup is unplugged or turned off, and you’ll also want to get some assistance if you are unfamiliar with DIY RVing.

Removing old water heaters is much easier than installing a new one, but I’ll tell you how to do it later!

RV’s Wiring

It’s important to inspect the electrical wiring that will be used for your new electric tankless water heater.

For you to get the most out of your new electric tankless water heater, you should hire an RV repair professional or electrician to help you through this process if you are new to it.

When inspecting your vehicle battery you need to make sure that you are not hooked to shore power. You do not want to injure yourself while you are inspecting potential bare wires.

Install Electric Tankless Water Heater

Have your new electric tankless water heater installed by a professional. You’ll need someone who knows what they’re doing when it comes to installing your new electric tankless water heater.

When you install your new electric tankless water heater yourself, be sure to follow the instructions of the manual carefully, and take your time to make sure the job is done properly. Always follow the manual, and don’t be in a hurry to put it together.

Types of Tankless Water Heater

Tankless water heaters come in two varieties: gas and electric.


A gas-powered tankless water heater is fueled by propane or, less commonly, kerosene or gas. It requires a gas source and pipe to deliver the gas to the heater.


Electric heaters are much more environmentally-friendly than propane heaters. They are also cheaper to operate than gas heaters, and they are much easier to install if you do not have an existing propane system already in your RV.
