Photos of tank water heater replaced with Tankless Water Heater
Tankless water heaters provide all the hot water you need without a reserve of hot water in a storage tank.
The benefit of Tankless is less energy consumption, as there is no fuel used to keep the water in a storage-tank hot. Instead, a Tankless water heater heats only when hot water it’s being used.
According to the U.S. Department of Energy (DOE):
- If your daily hot water usage is under 40 gallons, a tankless water heater saves 1/4 to 1/3 of the fuel used by a tank water heater.
- If your daily consumption is higher than 40 gallons, a tankless water heater will save up to 15% of the fuel used to heat water.
Note: A typical shower uses 17 gallons of water. The amount of hot water used is determined by how hot the shower water is set to.
How A Tankless Water Heater Works:
GAS Tankless Water Heater
ELECTRIC Tankless Water Heater
- Water heater senses the demand for hot water. When a faucet calls for hot water, the heating source (burner for gas and heating element for electric) in the Tankless Water Heater is activated.
- The Heat-exchanger heats up. Once the energy source is activated, the heat-exchanger inside the unit heats up very fast. The heat-exchanger then transfers heat to the water as it passes through.
- Water is heated and sent to the tap. As cold water passes through the water heater, it absorbs heat from the heat exchanger. The heated water is then delivered to the tap.
- When the faucet is turned off Water Heater also turns off. It restarts when hot water is needed again. After the demand for hot water ends, the water heater turns off until the next hot water demand occurs.

Tankless water heaters have different capacities (to deliver hot water). Much like a larger tank water heater, Tankless Water Heaters are rated at how many gallons of hot water they can deliver in 1 minute. The more bathrooms you have, the higher the delivery-rate (of hot water) you will need.
Whole-House Tankless Water Heaters deliver 2.5 gallons per minute (gpm) up to 5 gallons per minute. The correct size is determined by the installer, to ensure you always have all the hot water you will ever need.
If your demand for hot water exceeds 5 gpm — two Tankless Water Heaters connected together. The first unit will heat the water to the point that the water temperature entering the second unit is already high (as compared to the temperature of the water coming into the house from the city’s water line). This allows the second unit to deliver hot water at a higher rate than it’s capacity (alone) would allow.
