Tankless Water Heaters FAQs

What Are the Benefits of a Tankless Water Heater?

Between your showers, baths, laundry, and dishwasher, your home may be using a lot of hot water. Because a hot water tank has a limited capacity, tank-style heaters can run out of warm water.

Tankless systems are ideal for homes with high hot water demands. The benefits include:

  • Endless, on-demand hot water supply because water is heated instantaneously.
  • Lower energy consumption since water is not constantly being heated.
  • Increased home safety. Tankless systems usually need fewer repairs and because there isn’t a tank full of water, you reduce the risk of flooding.

Why Are Tankless Water Heaters More Energy Efficient?

Tankless water heaters heat water as it passes through your home’s plumbing. This means water is only heated when you need it. Hot water tanks keep a reservoir of water constantly hot, burning fuel night and day.

Most homeowners can expect to use up to 30% less natural gas after installing a tankless water heater. There’s no standby loss or water waste.

How Long Does a Tankless Water Heater Last?

Tankless water heaters typically last longer than a conventional hot water tank. If properly maintained and cared for, a tankless water heater can last for 20 years. This is 2-3 times the average life of a tank-style heater.

Although installation costs are higher, over time, a tankless system saves you money by being more reliable, lasting longer, and lowering your energy bills.

How Do I Know My Tankless Water Heater Needs Repair?

If you’re not getting any hot water out of your taps or showerhead, then something is wrong with your water heater. There are other signs that tell you a repair might be needed:

  • Your water heater randomly turns itself off.
  • Leaks or drips from your tankless water heater.
  • Strange or loud noises coming from your tankless heater.
  • Hot water supply smells or tastes funny or is discolored.
