A tankless water heater heats water on demand as you use it, while a traditional tank water heater keeps a 40–80 gallon reservoir hot 24/7. Tankless units deliver endless hot water, use less energy, and last longer; tank-style units are cheaper to install and have higher peak flow capacity for simultaneous use.

Quick comparison

  • Tankless — Endless hot water, 20–30% lower energy use, 20-year life
  • Tank — Lower install cost, higher simultaneous flow, 10–12 year life
  • Tankless — Wall-mounted, saves floor space
  • Tank — Familiar, simpler, no descaling required

We install both. See our tankless water heater service, plus traditional water heater replacement.
