Tankless Hot Water Heater. Why are Tankless Heaters a game-changer?

The tankless water heater heats water using heating coils.

It often heats at a rate of three to five gallons per minute.

5 key differences between Electric and Gas tankless hot water heaters

We’re a local Buford leading installer for both electric and gas tankless water heaters.

  • Gas-type water heaters (Tankless, Energy Efficiency Factor: 0.75-0.85)
  1. This type of water heater is heavier in weight and can be driven by either natural gas or propane.
  2. These water heaters are regarded as cost-effective because gas is more economical than electricity.

  4. Gas-powered heaters are significantly less energy-efficient than their electric counterparts.
  5. They may require more maintenance from a technician.


  • Electric-type water heaters (Tankless, Energy Efficiency Factor: 0.85-0.98)
  1. Electric water heaters typically employ heating coils to heat the water, making them far lighter than their gas counterparts.
  2. When the price of power is high, these types of heaters can be very expensive to run or operate.
  3. The initial unit costs can be less expensive than gas water heaters.
  4. Electric heaters are very energy efficient.
