Types Of Water Heaters



Tankless Water Heater img1

A tankless water heater is generally considered more energy efficient because they heat water only as it is needed. When the tap is turned on, the heater goes to work and supplies continuous hot water. A tankless water heater requires less space and can hang on a wall. It may require larger gas lines, special venting or additional electric circuits that could add to upfront costs but is well worth the investment. Tankless waters heater have a life expectancy of 15-20 years and can reduce water heating bills by as much as 30 percent.


Conventional Water Heater img2

Conventional water heaters store water in a tank and are available in a variety of gallon capacities. Electric or gas energy is required to maintain the water at a set temperature until a faucet is turned on and water is pulled through the pipe. A conventional electric or gas water heater should last about 11 years. Newer conventional water heaters are more energy efficient than older models. A high-efficiency model can reduce water heating bills by about 7 percent.


Hybrid Heat Pump Water Heater img3

A hybrid water heater combines conventional tank storage with a heat pump that extracts heat from the air and uses it to help heat the water. A hybrid water heater uses existing water and electrical connections, and can reduce water heating costs by almost 60 percent.
