Energy Efficient Water Heater

An energy efficient water heater is important because heating water for your home is second only to heating and cooling your home when it comes to your energy dollars. 

In the past, electric water heaters have not generally been an energy efficient hot water heating system… nor have they been environmentally friendly. But now there is a brand new integrated air-source heat pump water heater from Rheem, called the HP-50, which 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! 

Energy Efficient Water HeaterThis energy efficient hot water heater is a 50 gallon tank, but it’s only 21 inches in diameter – a great, slim design that is ideal for both new homes and drop-in replacement of your existing water heater. The Rheem HP-50 is Energy Star qualified and… the best part… this energy efficient hot water heater qualifies for a federal energy tax credit… as well as many local rebates and incentives. If you currently have a gas water heater – and have 240 volt access nearby – you can even replace your gas water heater with this more energy efficient hot water heater. 
Another great feature, a touch pad control panel that gives you complete temperature control.  It’s important to dial down the temperature setting on your hot water heater to avoid a scald risk.  Besides allowing an easier way to dial up or down the water temperature to suit your needs, the Rheem HP-50 control panel has several settings to help you save energy – including a vacation setting. 
The Rheem HP-50 is a very energy efficient water heater. It’s cheaper to run than an electric OR gas water heater. And its energy star rating allows it to qualify for a federal tax credit… and possibly even local credits through your state or utility company. To learn more about the Rheem HP-50 visit

  1. Found the “article” on the Rheem new electric hot water heater but would have appreciated a comparison to the tankless water heating products available. Had to replace my oil heating system a number of years ago. Was unable to get a conversion to gas, in spite of local utility promotions of same and none of the contractors who responded to calls mentioned any hot wather method other than a coil in the burner or a separate oil water heater.
    Last few years there have been articles about tankless water heaters being efficient and cost effective but see few promotions from utilities.
    No one discusses the longevity of tankless water heaters and this new Rheem electric system.
    Is the cost and longevitity of the system worth investing.

  2. In my opinion, both technologies have the same goal (saving energy and lowering utility bills). You will just need to decide which technology works best for your situation and geographical location.

    Tankless gas water heaters
    Pros & Cons:
    Models with .82 energy factor or greater qualify for federal tax credit
    Heats water only when the hot water faucet is on
    Small, compact size – about the size of a desktop computer
    Pre-qualifying suggested because they require a minimum gas pressure and 3/4-in supply line
    Venting is extra (indoor models) and is quite expensive which adds to the installation cost
    Limited warranty of 12 Year/heat exchanger; 5 Yr/Parts; 1 Yr/Labor
    Average retail about $1000 for the largest whole home model (unit only)

    Heat pump water heater
    Pros & Cons:
    Way more energy efficient than tankless (2.0 energy factor) and qualifies for fed tax credits
    Is a 50-gallon tank-type storage water heater
    Much larger than tankless (75-in tall, 21-in diam, 25-in from front to back)
    No pre-qualifying; It is all electric and used as a replacement model – best in attic, basement, or garage
    No extra venting costs – just don’t forget to drain the condensate generated by the heat pump
    Limited warranty of 10 Years on tank and parts, 1 Year labor

    Payback: go to for payback info and how the heat pump technology works for water heating
    Payback on the tankless is more difficult to figure because of so many variables for installation (pre-qualifying, venting, installation costs, etc)

    I hope this helps.

    Have a great day!
