Heat Pump Water Heater vs. Tankless: Compare Demand, Space and Total Cost

How Long Do Tankless Water Heaters Last? About 20 Years, and What Gets Them There

Tankless Water Heater Pros and Cons: Four Advantages, Five Trade-Offs and Who Should Switch

How Long Does a Water Heater Take to Heat Up? Gas 30 to 40 Minutes, Electric 60 to 80

How Often Should You Flush a Tankless Water Heater? Once a Year, Twice With Hard Water
Flush a tankless water heater once a year, or every six months if you have hard water. Minerals build up inside the heat exchanger and choke its flow, and a few signs tell you a flush is due.
