Tank vs. Tankless Water Heaters

B.32 Tank vs. Tankless

Are you thinking it’s time for a new water heater, but aren’t sure if you should lean towards a tankless or traditional? Before making a large purchase it is crucial to understand the pro and cons of each type as well as which one fits your family needs.


Traditional water heaters work by utilizing a tank which stores pre-heated gallons of water. The tank refills with water when the pre-heated water is used and the cycle continues.
Cost: less upfront costs than a tankless water heater and simpler to replace
Utility Bill: with a tank it is constantly working to heat & reheat water to the temperature you set, so a higher utility bill can be expected
Size: occupies more space and may be difficult to find a location for it
Less Dependable: there’s the possibility of running out of hot water with the tank option
Lifetime: 10-15 years


Tankless water heaters work by warming up cool water via a heat source on-demand rather than storing the hot water in a tank.
Saves Energy: according to Energy.gov tankless water heaters can be 24%-34% more energy efficient than traditional water heaters
Size: more compact and can fit in more places than a traditional water heater
Lifetime: 20+ years
Dependable: 2-3 gallons produced per minute on demand
Higher Cost: has a higher upfront cost when compared to traditional water heaters
Additional Costs: there may be additional install charges since it requires a  different procedure to set it up

If you are still contemplating which water heater is best for you the decision will most likely come down to matching your budget as well as your family needs. If you are able to afford the higher upfront costs of the tankless option this would be the best option for your home in the long run.
