The Pros & Cons of a Tankless Water Heater

Tankless water heaters have rightfully been growing in popularity among Indianapolis homeowners looking for an energy-efficient and space-saving alternative to traditional water heaters.

However, like any major appliance, they come with their own set of advantages and disadvantages. If you’re considering upgrading your system, it’s important to consider these pros and cons of a tankless water heater so you can make an informed decision.

 

Pros of a Tankless Water Heater

Endless Hot Water

One of the biggest draws of tankless water heaters is the fact that they can provide you and your home with endless hot water. Traditional water heaters feature a tank that is filled and then heated. Once that water is used up, you need to wait for the tank to refill and heat the water again, which leads to dips in your available hot water.

A tankless water heater instead heats your water on demand, giving you a continual supply of hot water whenever you need it—no need to wait for your tank to refill or heat back up.

 

Energy Efficiency

Again, tankless water heaters are designed to heat water only when you need it, unlike traditional models that keep a large tank of water hot all the time. This can significantly reduce energy usage, potentially lowering your utility bills. According to the U.S. Department of Energy, tankless water heaters can be 24-34% more energy-efficient for households that use less than 41 gallons of hot water daily.

 

Space Saving

Without needing bulky water tanks like traditional heaters, tankless water heaters are able to take up much less space. In fact, they can often be mounted on the walls, freeing up valuable floor space in your utility room, basement, garage, or wherever else you decide to place your water heater.

 

Longer Lifespan

Tankless water heaters are designed to outlast their traditional counterparts by many years. While conventional water heaters typically last around eight to twelve years, tankless systems can last 20 years or more with proper maintenance. This extended lifespan not only translates to long-term cost savings but also reduces the frequency of replacements, minimizing environmental impact and hassle for homeowners.

 

Cons of a Tankless Water Heater

Higher Upfront Costs

One of the biggest cons of tankless water heaters is the initial cost. The unit itself is more expensive than a traditional water heater, and installation can be more complex, requiring professional help. Depending on your home’s existing plumbing and electrical setup, you may also need upgrades to accommodate the system.

However, it’s important to note that the higher upfront costs are often offset by the long-term energy savings and extended lifespan of the system, making it a cost-effective investment over time.

 

Limited Flow Rates

While tankless water heaters are known for providing endless hot water, they can struggle to supply hot water to multiple fixtures simultaneously. The more appliances or outlets you have using hot water at the same time, the more likely it is that your water pressure will decrease. Larger households might need multiple units to meet their hot water demands.

 

Slight Delay on Hot Water

While the system heats water on demand, there can still be a slight delay as the water travels from the unit to your faucet or shower. This might change as time goes on and your system becomes used to the new heater, but it is important to keep in mind at the beginning if you’re someone who is used to instant hot water.
