Investing in a new hot water heater is not only about choosing the right appliance, but also considering its long-term impact on your energy bills and household efficiency. Water heaters are the second-largest electricity consumer in most homes, typically accounting for 18% of monthly electric costs, according to the U.S. Department of Energy. This significant cost, along with the growing emphasis on eco-friendly appliances, has made tankless water heaters an appealing option for many homeowners. However, before making the switch, it’s important to understand the full range of benefits and potential drawbacks of tankless systems to determine whether they’re the right fit for your home.
If you’re transitioning from a traditional tank-style water heater, you should know that tankless systems operate quite differently. Tankless systems heat water on demand, meaning they do not store water like tank-style models do. Instead, they provide hot water as you need it, offering some notable energy and space-saving benefits. But these systems also come with unique considerations. Below is a breakdown of the pros and cons of tankless water heaters.
One of the biggest selling points of tankless water heaters is their energy-saving potential. Because they don’t need to keep a large tank of water heated at all times, they use 30-50% less energy than traditional tank-style systems. For households using gas or propane-powered models, this could translate to savings of $100 or more per year. Electric-powered tankless systems offer slightly lower savings, reducing energy bills by approximately $44 annually. Either way, tankless systems provide a more energy-efficient solution, helping to lower your carbon footprint and save on utility costs.
Traditional water heaters can take up a lot of space in your home. By contrast, tankless water heaters are compact and can be mounted on the wall, freeing up valuable floor space. This is particularly beneficial for homes with limited utility room or storage space, as the smaller design can open up more room for other uses.
Unlike tank-style systems that can run out of hot water after heavy usage, tankless water heaters deliver a continuous supply of hot water. Whether you’re doing laundry, washing dishes, or taking back-to-back showers, you won’t have to worry about running out of hot water—provided the unit is correctly sized for your household’s needs.
The compact design of tankless systems contributes to less waste over time. Traditional water heaters have large tanks that can rust and deteriorate, eventually needing replacement and disposal. Tankless models eliminate the need for a large tank, which helps reduce the amount of discarded materials that end up in landfills.
While traditional tank-style water heaters generally last about 10-15 years, tankless water heaters typically last over 20 years. This extended lifespan makes them a more durable and long-lasting investment for homeowners.
Tankless systems often come with longer warranties, typically around 15 years, compared to the 6-year average for tank-style water heaters. This longer warranty period provides added peace of mind and protection for your investment.
For those opting for propane or gas-powered tankless water heaters, you may qualify for a $300 federal tax rebate. Additionally, some states offer additional incentives, further lowering the overall cost of purchasing and installing a tankless system.
One of the most significant downsides of tankless water heaters is their higher upfront cost. While smaller, more affordable units are available, they may not provide enough hot water for larger households. Larger units that meet the demands of a full household tend to be more expensive. Additionally, because tankless systems use high-powered burners, they require special venting through a dedicated, sealed vent system, making professional water heater installation a must. This specialized setup increases the initial investment, but many homeowners find that the long-term energy savings makeup for the upfront expense.
One of the key limitations of tankless water heaters is their ability to serve multiple hot water sources simultaneously. For example, if you’re taking a shower while the dishwasher is running, you might experience a drop in hot water pressure, resulting in a cold shower. To avoid this, some homes choose to install additional point-of-use tankless systems at different locations within the home, which increases both cost and complexity.
Homes that rely solely on electric utilities may need to make costly upgrades to support a tankless water heater. For instance, older homes may require an upgrade to the electrical system to provide sufficient power to run the tankless model efficiently. This could involve extensive rewiring, along with the expense of hiring a licensed electrician. Depending on the extent of the work needed, these upgrades can add a significant 4-digit cost to your installation bill.
Choosing between a traditional tank-style water heater and a tankless model can be a tough decision. Tankless water heaters offer many compelling benefits, from energy savings and space efficiency to a longer lifespan and reduced environmental impact. However, they also come with higher upfront costs and may require additional modifications to your home’s existing utilities.
