Gas vs Electric Tankless Water Heaters: A Buyers Guide

gas vs electric tankless water heater

Are you in the market for a new water heater? Choosing the right one for your home can be overwhelming with so many options. One of the most significant decisions you’ll need to make is whether to go with a gas or electric tankless water heater.

Both types have advantages and disadvantages, so weighing the pros and cons before deciding is important. In this article, we’ll compare gas vs electric tankless water heaters to help you make an informed choice that fits your needs and budget.

So, whether you’re looking to save money on your energy bills or want a more eco-friendly option, read on to learn more about gas vs electric tankless water heaters.

How Does A Tankless Water Heater Differ From A Traditional Water Heater?

A tankless water heater, also known as an on-demand water heater, is a type of water heater that heats water as needed instead of storing it in a tank. This means that hot water is available on demand, and the unit only heats water when needed, saving energy and money in the long run. In contrast, a traditional water heater stores hot water in a tank and constantly heats it to maintain a set temperature. This can result in wasted energy and higher utility bills. Overall, a tankless water heater provides a more efficient and cost-effective solution for heating water in a home or business.

Types of Tankless Water Heaters

Tankless water heaters are a great alternative to traditional water heaters that store hot water in a tank. They provide hot water on demand, meaning you only use energy when needed, making them more energy-efficient and cost-effective. There are two types of tankless water heaters: electric and gas. Electric tankless water heaters are smaller and more affordable, making them an excellent option for smaller homes or apartments. Gas tankless water heaters are larger and more expensive but are more powerful and can provide hot water to larger homes or commercial buildings. Both types have benefits and drawbacks, so it’s essential to consider your specific needs and budget before choosing which one to install.

Similarities Between Gas vs Electric Tankless Water Heaters

When comparing gas vs electric tankless water heaters, some similarities exist.

Hot Water On Demand

Both types of tankless water heaters provide hot water on demand, meaning you won’t have to wait for a traditional storage-tank water heater to fill up and warm up. This can save you money on your energy bills since you’re only heating the water you need at any time.

Long Lifespan

Another similarity between gas and electric tankless water heaters is their long lifespan. Both types can last up to 20 years or more with regular maintenance, while standard tank-style water heaters typically only last 8-12 years.

Differences Between Gas vs Electric Tankless Water Heaters

While there are some similarities between gas and electric tankless water heaters, there are also some key differences.

Energy Efficiency

Gas tankless water heaters have a higher thermal efficiency rating, which means they can heat more water with less energy than electric models. Gas water heaters use fossil fuels to operate and require a gas line installation, but they can save homeowners money on energy bills in the long run. Electric tankless water heaters tend to have lower initial and installation costs but may lead to higher energy bills over time.

Flow Rates

Another factor to consider when choosing between gas and electric tankless water heaters is the gallons per minute (GPM) flow rate. Gas models tend to have higher flow rates, which makes them more suitable for larger households with high hot water demands. Electric models may struggle to keep up with the hot water needs of larger households but are ideal for smaller homes or apartments with lower hot water usage.

Upfront Cost

The initial cost of purchasing a gas tankless water heater is typically higher than that of an electric model due to gas line installation requirements. However, gas units have longer life spans than electric tankless water heaters, which can offset the higher initial cost over time. Electric tankless water heaters have a lower upfront cost and can be easier to install but may need to be replaced more frequently.

Environmental Impact

Regarding environmental impact, gas tankless water heaters produce carbon emissions and contribute to climate change. Electric models do not produce direct emissions but may contribute to emissions indirectly depending on the source of the electricity used in their operation.

Installation Considerations

When deciding between gas and electric tankless water heaters, it’s essential to consider the installation requirements of each type. Gas units require a gas line connection, while electric models can be installed without major modifications.

Maintenance Requirements

In addition to proper installation, maintenance is important when deciding between gas vs electric tankless water heaters. Gas models require frequent maintenance due to their reliance on combustion and venting systems. Electric models do not require as much maintenance but should be inspected periodically for any wear or damage. Regularly checking for leaks and replacing worn parts can help ensure your tankless water heater runs efficiently for years.

Ultimately, choosing between a gas or electric tankless water heater will come down to your preferences and needs. Both options have pros and cons, but with the right research and consideration, you can make an informed decision that will keep your home comfortable and efficient for years.
