Tankless Water Heaters vs. Storage Tank Water
Storage tank: Our payback calculations are based on replacing a 50-gallon storage tank water heater with a tankless water heater, then calculating how much the tankless model costs to operate and
Which Water Heater Is Right for You? | Department of
Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed, eliminating standby heat loss. Lasts about 20 years. 8%-34% more efficient than storage
Estimating Costs and Efficiency of Storage, Demand,
Determining Energy Efficiency of Storage, Demand, and Heat Pump Water Heaters. UEF ratings are determined by assigning water heaters into one of four different categories of hot water usage and then evaluating their performance
Estimating Costs and Efficiency of Storage, Demand, and Heat Pump Water
The higher the uniform energy factor, the more efficient the water heater. However, higher energy factor values don''t always mean lower annual operating costs, especially when you compare
Storage Water Heaters
A single-family storage water heater offers a ready reservoir -- from 20 to 80 gallons -- of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water
Storage Water Heaters | AHRI
Some storage water heater models have heavily insulated tanks that can reduce heat losses and reduce the demand for fuel to heat the water. Insulation between the storage tank and the outer jacket slows this heat loss, but cannot eliminate

Selecting a New Water Heater | Department of Energy
For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. Also, an electric heat pump water heater might have lower
Heat Pump Water Heaters
Heat pump water heaters require installation in locations that remain in the 40º–90ºF (4.4º–32.2ºC) range year-round and provide at least 1,000 cubic feet (28.3 cubic meters) of air space around the water heater.
Water Heater Buying Guide: Here''s How to Make the Right Pick
"Storage water heaters, also called tank water heaters or traditional water heaters, use electricity or gas for heating water," said Kelly Russum, owner of KC''s 23 ½ Hour Plumbing and Air
6 FAQs about [Air energy water heater storage]
How does a storage water heater work?
A single-family storage water heater offers a ready reservoir -- from 20 to 80 gallons -- of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank through the dip tube where it is heated, ensuring that the tank is always full.
Can a heat pump work with a storage water heater?
You can also retrofit a heat pump to work with an existing conventional storage water heater. Heat pump water heaters require installation in locations that remain in the 40º–90ºF (4.4º–32.2ºC) range year-round and provide at least 1,000 cubic feet (28.3 cubic meters) of air space around the water heater.
How do I choose a storage water heater?
Some storage water heater models have heavily insulated tank, which significantly reduce standby heat losses and lower annual operating costs. Look for models with tanks that have a thermal resistance (R-Value) of R-24 and above to avoid adding an insulation blanket (electric water heaters only).
How much space does a water heater need?
Because the heat pump adds height, the water heater needs more headroom than a conventional tank, at least 7 feet. They also need about 1,000 cubic feet of surrounding air to draw from, about the amount circulating in a 12-by-12-foot room. Check for rebates.
What kind of fuel does a storage water heater use?
Conventional storage water heater fuel sources include natural gas, propane, fuel oil, and electricity. Learn more about fuel types available when selecting a new water heater.
What is the difference between energy storage and passive heating?
For water heating, energy storage as sensible heat of stored water is logical. If air-heating collectors are used, storage in sensible or latent heat effects in particulate storage units is indicated, such as sensible heat in a pebble-bed heat exchanger. In passive heating, storage is provided as sensible heat in building the elements.
