We get this question often: what’s a tankless water heater and should I get one? There are many benefits to tankless water heaters (also known as on-demand water heaters) and might be just what your household needs.
How They Work
Conventional water heaters store water and heat it up via an electric or gas burner while in the tank. The water is then pushed through pipes to whatever faucet has the hot water valve open. Tankless water heaters operate by drawing cold water through a pipe into a heat exchange which then pushes hot water to your pipes.
So what type of water heater is best for your situation? Like anything in life, it’s important to review the pros and cons. Let’s break down the good, the bad, and the ugly.
Benefits of a Tankless Water Heater
Instant hot water
Hot water at your fingertips nearly instantly. This is probably the largest appeal of tankless water heaters.
They are a lot smaller in size than conventional water heaters allowing them to fit in small or tight spaces.
Less water waste
No more running the water first before getting in the shower.
The average lifespan of a conventional water heater is 10 to 15 years while a tankless water heater is expected to last 20+ years.
Use less energy
Tankless water heaters use 30 to 50 percent less energy than conventional water heaters. Less energy = lower energy bills!
Some tankless water heaters qualify for federal tax credits. (This can help offset the upfront costs!)
Disadvantages of a Tankless Water Heater
If you’re going to use this in a large house, you’ll need a larger unit and/or several smaller units. The upfront costs can add up. (But remember, they last longer!)
Tankless water heaters typically can’t supply enough hot water for simultaneous usage. For example, you may not be able to shower while running a load of laundry.
One of the biggest complaints is inconsistent temperatures. This is typically due to simultaneous usage and can be remedied by installing a smaller unit dedicated to one faucet such as a washing machine.
Venting is a must
Tankless gas water heaters must be vented to the outside.
