Tankless water heaters are gaining huge popularity thanks to their energy efficiency, longer lifespan, and space-saving design. These water heaters work differently from traditional tank-based water heaters in that they provide hot water on demand. There are two main types of tankless water heaters:
If you’re considering installing a tankless water heater in your home, it’s important to understand the key differences between these two types of water heaters. At Mr. Rooter Plumbing, we specialize in tankless water heater installation and water heater repair. We are conversant with the working mechanisms of both types of water heaters. Read on to learn more about gas vs. electric tankless water heaters.
As the name implies, gas tankless heaters use natural gas or propane as their energy source, while electric tankless heaters use electricity as their energy source. Apart from the energy source, there are several differences between these tankless water heaters.
This is one of the major considerations when choosing between gas and electric tankless water heaters. Gas tankless water heaters tend to be more energy-efficient than their electric counterparts. They can achieve higher flow rates and provide hot water for multiple fixtures simultaneously. On the other hand, electric tankless water heaters are highly efficient when providing hot water for a single fixture or low-flow applications. However, their capacity decreases as demand increases.
Electric units are compact and can be installed in various locations, including under sinks or in closets. They are suitable for homes with limited space or no access to natural gas. Gas units require proper ventilation and gas line connections, which can increase installation complexity and cost.
Electric tankless heaters have a lower upfront cost compared to gas units. Installation is more straightforward and affordable. Although gas tankless heaters have a higher upfront cost due to installation requirements, they tend to have lower operating costs over time, especially in areas with low natural gas prices.
Electric tankless units do not produce direct emissions on-site. While gas tankless units are more energy-efficient, their combustion process produces carbon emissions. However, some condensing gas models are designed to capture and reuse heat, thereby reducing emissions.
When you’re looking to install a tankless water heater, it’s important to evaluate all the key differences we’ve highlighted above to make an informed choice. You can consult with a plumbing service that specializes in tankless water heater installation and water heater repair.
