Pros and Cons of Tankless Water Heaters

It’s fun and typically useful to have the latest technology, whether that’s the newest smartphone or kitchen gadget. If it’s time to replace the water heater in your home, you may have your eye on a tankless unit, also called an on-demand a water heater.

Tankless Water Heaters Pros Cons

Tankless hot water heaters have grown in popularity over the last decade or two. And there are many aspects to like about these systems. Of course, just like with any new technology, there are advantages as well as disadvantages.

Pros of tankless water heaters

  • More energy efficient. Tankless water heaters create hot water on-demand, instead of storing dozens of gallons in a tank like traditional units. This approach can be 30-50% more efficient, which saves you money on your monthly energy bill and is good for the environment.
  • Never-ending stream of hot water. Since water is heated right when you need it, a tankless water heater never runs out of hot water. If you have a large household and have ever experienced a cold shower because the tank system ran out of water, you’ll appreciate having a continuous source of hot water.
  • Saves space. Tankless water heater units are significantly smaller than traditional systems since they don’t require bulky tanks. The small boxes and pipes can be installed on a wall, which saves you room and opens up floor space in your home.
  • Longer service life. When looking at the total cost of ownership, another attribute that helps tankless water heaters is longer service life. Whereas tank units last 10-15 years, you can expect 20 years or more out of a new tankless system.
  • No tank to leak. Many homeowners find out they need a new water heater when the tank leaks, which can result in costly water damage. With a properly installed tankless unit, your risk of water damage is much lower.

Cons of tankless water heaters

  • Higher price tag. While prices are slowly coming down, the average cost of a new tankless water heater is still more than a tank system. The idea is that you’ll make this money up in the long run with lower monthly energy bills.
  • More complicated installation. Tankless systems are not installed the same way as tank water heaters. If you’re having a tankless unit installed in your home for the first time, your plumber may need to run new pipes or venting system.
  • Inconsistent temperature when multiple outlets are used at once. If a few people are using hot water simultaneously (showers, laundry machine, dishwasher, etc.), a tankless water heater may not be able to keep up at once. Once the demand goes down to one outlet, the tankless system will go back to providing unlimited hot water.
  • Short delay in hot water delivery. The first thing some people notice after having a tankless water heater installed is there can be a slight delay in turning on the faucet and having hot water. This is because it takes a few seconds for the water heater to heat up the water and send it through the pipes to the faucet.
  • No hot water when power is out. Since a tankless water heater works on-demand, it shouldn’t be a huge surprise that it can’t create hot water when the electricity is out. This isn’t a major concern for our customers, but something to keep in mind.
