Are Tankless Water Heaters Truly More Efficient?

tankless-water-heaterYou may have heard all kinds of things about the efficiency and performance of tankless water heaters, especially if you’re doing your research into water heater upgrades. You might have a tank water heater right now, or maybe you’re just wondering if your tankless water heater is really the best choice for your home.

If you’re debating whether a tankless water heater is truly the most efficient option for your home, we’ll help you figure it out below.

How Are They Better Than Tank Water Heaters?

Although this is the question most people ask, it’s not exactly the right question. That’s because tankless water heaters are far superior to tank water heaters in certain situations. The things that make tankless options great is not going to be the best thing for everyone, but they’re certainly hard to contest with.

  • On-Demand Only: Tankless water heaters only operate when hot water is needed, as opposed to heating water in reserve. This helps homeowners save hundreds of dollars in heating costs.
  • More Efficient: Since there’s no tank storage, there’s no energy lost from standing warm water—the biggest reason for inefficiency in tank water heaters.
  • Smaller: Tankless water heaters are only a couple feet wide and tall and can be bolted into the wall, inside or outside of the house. Compare that to a tank water heater which stands at nearly 5 feet tall and occupies around 3 feet of space on the ground.

Why This Isn’t the Best for Everyone

The above are some of the best benefits for getting a tankless water heater, but again, your personal situation will dictate if you’ll be able to use a tankless water heater to it’s highest potential.

  • Family Size: How many people are in your home? Are they all using hot water independently, or together? A tankless water heater is great at creating hot water on demand, but it takes a lot of power to provide that energy to several appliances at the same time. More people in the house means more hot water use, meaning the limitations of the tankless water heater will be more prevalent. A tankless heater that provides hot water for multiple appliances will cost more.
  • Installation: A tankless water heater will definitely lower your monthly energy bills, so you might not be surprised to hear that tankless heaters are an investment. The initial installation costs are more expensive than tank units, especially if you decide to install a gas-burning heater instead of an electric one.
  • Electricity: If you plan to consolidate your energy use from gas and electric to all electric, a tankless heater can help you do that. However, be aware that some tankless heaters will require more power, and that can mean upgrading your home’s electrical service.
