Let’s take a look at the pros and cons of tankless hot water heaters. We’ll also share a few observations about the technology to help you make an unbiased decision as to whether or not replacing your hot water heater with a tankless option is right for you.

The Pros

A tankless hot water heater can save energy compared to a conventional hot water heaters. You only heat up the water as you use it.

This reduces how much energy you use to heat water by up to half. This can offset the purchase and installation costs in a couple of years. If you want to learn more about tankless water heaters and how much you can expect to pay for installation, you can click here for more information.

Tankless heaters can heat as much or as little water as you need. This means a tankless hot water heater could supply hot water for an hour-long shower or multiple rounds of dishes, laundry, and showers.

Tankless hot water heaters take up very little space. It is a far better choice than installing a larger hot water heater. This means you could install them in a small house, apartment, bathroom or basement.

Tankless hot water heaters have a 20-year lifespan – or more. However, the greatest benefit of a tankless hot water heater is that you don’t run the risk of serious water damage that occurs when a hot water tank fails. That could flood forty to sixty gallons of water on your floor.

Another great thing about tankless hot water heaters is their repairability. You can generally repair a tankless heater by replacing the specific part that has failed. If a standard hot water heater dies or breaks, you may have to replace the entire thing.

The Cons

While tankless hot water heaters can supply one steady stream of hot water, it doesn’t have reserve capacity. You could take a long shower and have constant hot water, but you may not be able to take that same hot shower and use hot water in the clothes washer.

Conversely, a hot water heater could supply multiple draws until it runs out. You can install several tankless hot water heaters in parallel or dedicate them to separate appliances, but that significantly increases the installation costs. This makes tankless heaters not always the best option if you have a large household and have large hot water needs.

Observations about Tankless Hot Water Heaters

There are both electric and gas-fired tankless hot water heaters. A gas-fired tankless hot water heater requires a gas connection, of course. You probably want one with an intermittent ignition device instead of a standing pilot light. This saves gas.

Tankless hot water heaters bring fewer risks than a conventional hot water heater, but they do require maintenance.

You may be able to save money by renting instead of buying a tankless hot water heater. However, most tankless systems will save you enough money on energy that you’ll recoup its cost within a couple of years.

Conclusion

Hot water is out of sight, out of mind until you run out of it. Tankless hot water systems can be a great way to enjoy unlimited hot water with lower energy bills, but that’s only true if you choose the right system for your situation.
