An essential function of a water heater is the hot water supply. Whether it’s for showering, laundry, or dishwasher, your household needs to have access to hot water.
Tankless water heaters are more efficient than traditional storage and can help save homeowners money on their energy bills. The Department of Energy estimates that homes with tankless models use up to 34 percent less energy than those with standard storage units.
When shopping for a new water heater, you should first look at its energy efficiency rating. This metric is determined by the Uniform Energy Factor, which rates each model in a category from 0.60 to 0.85.
In addition to its UEF rating, the Energy Star website lists the unit’s maximum gallons per minute (GPM). A high GPM capacity is necessary for larger households or colder climates, as it helps ensure that all plumbing fixtures can get adequate hot water.
Generally, gas-powered tankless water heaters have a higher GPM capacity than electric models. This is because gas heaters are more efficient and less costly, usually offering a better overall value.
However, they do require a gas line and venting system. If you’re unsure if your home has these requirements, consider an electric tankless water heater instead.
Another factor to consider is the size of your household and its hot water usage habits. An enormous home may not need as much hot water as a smaller family.
One of the best things about tankless water heaters is that they can be installed in tight spaces, such as in a small basement or utility room. These types of space savings can help you avoid losing valuable square footage and make the most of your available living area.
Lastly, tankless water heaters are often more durable than conventional water heaters. This makes them less likely to fail, causing water damage to your home. This is because they only heat water as you need and do not store large quantities of water in a storage tank, which can lead to leaks and flooding.
