Electric vs. Gas Tankless Water Heaters: Which One Is Right for Your Home?

If you're thinking about upgrading your water heater, chances are you've heard the buzz about tankless models. These compact, energy-efficient systems heat water on demand—meaning no more running out of hot water and no more paying to keep a giant tank warm 24/7.
​
But one of the biggest decisions you’ll face is choosing electric or gas. Both have their pros and cons, and what’s right for one home might not be right for another. At Tony’s Plumbing and Heating, we help homeowners all over Minnesota weigh their options. Here's what you need to know.

Understanding the Basics
A tankless water heater works by heating water only when you turn on the tap. As the water flows through the unit, it passes over a heating element (electric or gas-powered), instantly raising the temperature. That means no waiting for a tank to refill—and no paying to keep water hot all day long.
Electric and gas units do the same job, but how they get there—and how they perform over time—can vary significantly.

Why Choose an Electric Tankless Water Heater?
Electric tankless models are often seen as the more budget-friendly option upfront. They’re compact, quiet, and usually easier to install, especially in homes that don't have natural gas service. Because they don’t need venting like gas models do, you have more flexibility in where they can be placed.
These units work especially well in smaller homes or places with low to moderate hot water demand. They’re also a popular choice for add-ons like in-law suites or detached garages, where running a gas line would be costly or complicated.

However, in areas with higher electricity rates, the cost of running an electric unit over time might be higher than a gas model. And if you have a large family or tend to use multiple hot water fixtures at once, you might notice that electric systems can struggle to keep up, especially during cold Minnesota winters.

What About Gas Tankless Water Heaters?
Gas-powered tankless units shine when it comes to performance. They heat water quickly and deliver higher flow rates, making them ideal for larger households with heavier hot water needs—think multiple bathrooms, laundry, and the dishwasher all running at once.

If your home is already hooked up to natural gas, installing a gas unit might be the logical choice. While the upfront cost is often higher, especially if venting needs to be installed or upgraded, many homeowners find that the lower operating costs of natural gas offset the initial expense over time.
That said, gas units do require more complex installation, including proper venting for exhaust gases and a sufficient gas supply line. And like any combustion appliance, they require regular maintenance to ensure safety and efficiency.

What’s Right for Your Home?
The answer depends on a few key factors: your home’s existing energy setup, how much hot water your household uses at once, your budget for installation, and your long-term energy costs.
For smaller homes, apartments, or homes without gas access, an electric unit is often the best fit. For larger homes with multiple bathrooms or families with heavy water use, gas tends to provide better long-term performance and value.

If you’re still unsure, that’s where we come in.
