Most Energy Efficient Water Heater Available Now

Heating water for your home is the second most expensive utility bill you’ll pay. Only heating and cooling your home cost more. The best way to save money on hot water is to get the most energy efficient water heater you can.  If you’ve been thinking about replacing your water heater with something more energy efficient, there is a super energy efficient water heater on the market right now that may suit your needs.

The Rheem HP-50 is an intergrated air-source, electric heat pump water heater. Although electric water heaters have been expensive to run in the past, that is not the case with the HP-50. This is most energy efficient water heater on the market right now… more efficient than any electric or even gas water heater. It offers more than twice the energy efficiency of a standard electric storage water heater. The energy efficient design will help a family reduce its carbon footprint by nearly two tons every year! 
Another benefit of the Rheem HP-50 is that it is available now, through most plumbers. There is no special ordering required. It can also be installed by a typical plumber, without any special training needed.
If you’re expecting holiday guests, the Rheem HP-50 has a touch pad control that allows you to account for the extra water usage and make sure you don’t run low on hot water for all those showers! It also has a vacation setting to save even more energy while you are away.
Perhaps the biggest benefit is the cost. It’s energy star rating qualifies it for a federal tax credit and potentially state and even local utility companies, the Rheem HP-50 will pay for itself in no time. To learn more about the Rheem HP-50 visit

  1. I believe the most efficient water heaters on the market are the tank less water heaters but they are expensive. I do know gas water heaters are probably the best for your money. Investing in a water circulatory system might be something I would look into as well. Always install a thermo blanket for whatever water you buy.

  2. Tom’s comments are not quite accurate. The difference in heating capacity is measured in BTU’s , or, temperature rise at a given flow rate, and this has little to do with efficiency (ie, heating water by “x” degrees for “x” period of time).

  3. Rheem makes the GE hot water heaters, including this heat pump model. The hot water heater is identical except for the brand name. The confusion arises because there are three different modes to run the heater in, one of which is 2.0 EF, one of which is 2.5 EF according to the spec sheet my plumber sent over.

  4. Thanks for your comments, but the EF is not the whole story. Looking at just the EF doesn’t take into account the size of the water heater, or how long it takes it to heat the water. If one unit can heat 50 gallons of water in 6 hours, but it takes a different unit just two hours, that is energy efficiency that is not measured by the EF. So looking only at EF numbers across the board when comparing different brands, you cannot accurately make an apples to apples comparison. Secondly, one of the models you mentioned is not currently available in the U.S., and the Rheem unit is available right now, without waiting or special ordering. So we are pretty confident that the article is accurate and honest.

  5. The Rheem unit is definitely an energy efficient unit, but the Energy Star website lists other heat pump style water heaters that have higher energy factors and are therefore, more efficient. The website lists an 80-gallon Steibel Eltron model with a 2.5 energy factor, and a 50-gallon GE model with a 2.4 energy factor. The Rheem unit is only listed as a 2.0 energy factor, so the statement that Rheem is “The most energy efficient water heater available now” is inaccurate and misleading.
