Hybrid and Tankless Water Heaters
Tankless Water Heaters
Tankless water heaters use 30 to 50 percent less energy than traditional units. This can save a family about $100 or more per year, depending on water usage. Sometimes referred to as on-demand hot water heaters, tankless heaters only heat water when you turn on the faucet. They can operate on natural gas, propane, or electric. Their main advantage is eliminating the cost of keeping 40 to 50 gallons of water hot in a storage tank at all times. They also offer a continuous supply of hot water and are more compact than a standard water heater since the can be mounted on a wall.
Hybrid Water Heaters
Hybrid hot water heaters move heat instead of creating it. A hybrid heat pump water heater absorbs heat from the air surrounding it and transfers it to the water, which is stored in a large tank. Your refrigerator uses the same type of technology. Refrigerators suck heat out of the refrigerator and deposit it outside the refrigerator, in your kitchen. The hybrid heat pump on the water heater does this in reverse by removing the heat outside of it and depositing it inside the water. Moving heat requires much less energy than creating it from scratch, which results in hybrid water heaters being more than twice as efficient as standard and tankless water heaters.
