HOW EFFICIENT ARE ELECTRIC TANKLESS WATER HEATERS?

Optimal heaters are highly efficient, by 99.9%. This means almost all the unit's electricity translates into water heating, minimizing energy waste. Here's a breakdown of the efficiency:

Advantages:

  • No standby losses: Unlike tank heaters that constantly heat and reheat water even when unused, tankless heaters only activate when you open a hot water tap. This eliminates standby losses, significantly reducing energy consumption.
  • Demand-based heating: They only heat water when needed, matching your hot water usage patterns and minimizing energy waste.
  • Reduced carbon footprint: Their lower energy consumption contributes to a smaller carbon footprint than traditional tank heaters.
ARE TANKLESS WATER HEATERS “INSTANTANEOUS”?

Optimal heaters are instantaneous directly from the heater, typically within 3 to 5 seconds of action. However, keep in mind the distance from the unit to the tap. The farther the faucet is from the heater, the longer it takes for the hot water to travel to the tap.

HOW MUCH CAN I SAVE WITH AN ELECTRIC TANKLESS WATER HEATER?

We estimated 30% to 60% energy savings compared to tank heaters. You can expect to save 30%–60% on your water heating costs, especially if your hot water usage is moderate, with an estimated  12 to 24-month payback period of any incremental cost going from tank to tankless, depending on the model perched.
