Review and Buying Tips

Explore the best heat pumps to buy online or offline, used for potable water heating in residential homes, and get the maximum savings, convenience, and comfort - no matter where you live. Check out the list and review of the top 50-gallon models and selling units in North America, and take advantage of the government and utility rebates and credits.

Heat pump water heaters (HPWH), also called hybrids, are the only electric models with ultra-high energy efficiency and Energy Star approval - resulting in great energy and water savings. This is what makes them a great buy.

However, before going into the buying tips, check out how a heat pump works, explore the types, check out the comparison table, explore advantages, benefits, installation, and buying tips.

As opposed to the electric-powered storage tank models that utilize heating elements to heat water, electric hybrid water heaters have the hybrid design for efficient water heating: heat pump for moving the warm air from surrounding to the water and heating elements as the backup or support.

During the summertime, the heat pump and its hybrid technology make the room environment comfortable for a living - the air gets colder and dryer, resulting in less energy used for AC. During the wintertime, its efficiency gets reduced, so it is not recommended in areas with a cold climate.

Review of the best heat pump water heaters

Electric heat pumps typically have higher initial costs than conventional storage-tank type, but they have lower operating costs, which can offset the higher purchase and installation costs; plus they are Eco-friendly as there are no exhaust gases as found on gas models.

The best heat pumps bring considerable savings to the homeowners as the energy efficiency is two-three times the value of the conventional models.

The heat pumps are as easy to install as the conventional electric units but are more complex and sophisticated and offer more flexibility and options by using advanced electronics.

To find the best heat pump water heater check the following features and data:

  • Look for the highest energy factor (EF) - most of the heat pumps have an efficiency of around 2, while higher is always better. The EF is an indicator of how much electricity is used per year or how much money you will save.
  • Size the unit properly as the smaller tank and insufficient capacity results in a lack of hot water and increased electricity usage. The most popular tank sizes are 50 and 80 gallons. For a family of four, 50-gal units are recommended.
  • Look for the model that is designed with the high First Hour Recovery, calculated in gallons per hour. This information allows you to estimate whether the water heater can provide enough hot water during the peak time or not.
  • Recovery rate is also very important, so the unit produces hot water fast enough, and you don't wait for hot water too long between two showers. Depending on your hot water usage pattern, make sure to buy the heat pump with a high recovery rating.
  • The quality of the elements is usually related to longer unit warranties. The heating elements should be made of quality material such as stainless steel and include dry-fire protection. The anode rods should provide years of corrosion-free operation - choose the model with powered anode or commercial grade anodes (more better). The foam insulation should be at least 2" thick and have an R-value high. To reduce the negative influence of the sediment build-up, look for the model with the self-cleaning system.

Conclusion

The best heat pump water heater is the high-efficient unit, Energy Star approved, is equipped with the quality components and high-tech features, commercial type anode rod, has excellent reviews, and is coming from a reliable and proven manufacturer.

The best heat pump heats water with less energy, provides more hot water when compared to its electric counterpart, saves energy of the dehumidifier, and makes other appliances work more efficiently.
