Tank Type vs Tankless Water Heater

If it's time for the old water heater to go, here are some considerations to take when making that decision. Our technicians will work with you to determine the perfect solution to your needs. Below are some differences between a tank type and tankless water heaters:

Tank Type Water Heater

tank type water heater
  • Quick replacement time (if replacing comparable tank)
  • Stored hot water for a limited amount of time during power outage
  • Less time servicing unit for annual maintenance
  • Less expensive installation cost

Tankless Water Heater

tankless water heater
  • 20-30% more efficient (energy savings)
  • Endless hot water
  • Takes up less space – tankless units hang on the wall and are about the size of a suitcase
  • 2-3 times the life expectancy with proper maintenance
