Traditional Storage Tank Heaters
Conventional tank water heaters are straightforward, reliable options, employing ages-old technology that remains effective. They operate using electricity, propane, oil, or natural gas. Typically, a tank holds 20 to 80 gallons, heating and maintaining water temperature within an insulated exterior. Hot water exits from the top, while cold water refills from the bottom. Modern models are more energy-efficient, with some earning Energy Star ratings. Transitioning between fuel types may involve minor modifications but generally doesn’t require extensive changes.
Although tanks are limited in size and may run out of hot water during peak usage, their simplicity and affordability offset this issue. They don’t involve complex piping or wiring alterations, which keeps installation straightforward.

Tankless Water Heating Units
While not a recent invention, tankless water heaters are increasingly popular nationwide. These compact units are wall-mounted and provide hot water on demand. Cold water enters the unit and is heated instantly using electric resistance coils or gas burners. They are about 30% more efficient than traditional models but tend to be pricier. Installation costs may also rise due to required modifications.
Tankless systems offer virtually unlimited hot water, making them ideal for busy households. However, simultaneous use—like showering and running a dishwasher—may reduce flow rates, affecting heating speed.
For purchasing tankless heaters, consider brands like:
Rinnai
American Water Heaters
Noritz
Takagi
EcoSmart
Navien
Choosing the appropriate water heater involves weighing factors such as initial costs, energy efficiency, household water usage, and duration of residence. Consulting with a qualified expert and conducting personal research will help in making an informed decision tailored to your needs.
