Tank Hot Water Heaters

Storage tank water heaters, or just tank water heaters, are the more conventional choice in hot water heaters. They store continuously heated water in a storage tank for use later on. There are some advantages and disadvantages with this hot water heater type, and knowing both sides can be helpful.


  • Lower purchase price
  • Simpler installation and simpler replacement result in lower costs for both
  • Several models are not operated by electricity
  • Fuel type options vary
  • Installation can occur almost anywhere in a building
  • Compatible with reticulation systems


  • Standby heat loss
  • Can run out of water during high usage times
  • Tanks are larger and take up much more space, as well as being heavy
  • Higher maintenance fees
  • Less precise water temperature settings

Tankless Water Heaters

Tankless water heaters heat cold water that passes through it via a gas burner or electrical elements and then supplies it to the pipes of a building without the use of any type of storage tank. There are also some advantages and disadvantages of this hot water heater type and it is important to understand it as a whole.


  • Lower maintenance costs
  • Hot water will never run out since it is made on–demand
  • Creates hot water as–needed which saves money and saves energy by not heating water that is never used
  • More precise temperature control
  • No tank means a smaller unit that saves space and is usually hung on a wall
  • Longer lifespan of up to three times longer
  • High efficiency: up to 80% more efficient than tank models
  • Tax credits are available due to their energy savings


  • Higher purchase price
  • More complex installation with larger fuel lines results in higher installation costs
  • Most models require electricity to run
  • Untreated water can produce scaling which reduces or halts water–flow
  • Freeze damage is a possibility if installed incorrectly
  • A minimum amount of hot water flow is necessary
  • Recirculation is more complicated and can negate the warranty
