Model selection

Reliance manufacturer produces two types of heat pumps; smaller 50-gallon (model 10-50-DHPST) and larger, 80-gallon (model 10-80-DHPT), the only two electric water heaters that are eligible for tax credits and frequent utility rebates. This review will show what the common features are, the pros and cons of both models.

Features and benefits

Great savings

Reliance heat pumps are very efficient as they employ the heat pump and the electric heating elements to boost the recovery. Such a combination brings great savings for the user and according to the manufacturer; the payback period is approximately three years.

Digital display

Reliance heat pumps utilize the digital display that allows you to set the temperature and operating modes, also check the operating status. The main difference is that the 10-80-DHPT model comes with the innovative design and large LCD display that shows the temperature, error code or operating mode, while the 10-50-DHPST uses the LED diodes for modes, and the smaller screen for temperature and error codes.


The heat pumps are protected by the anode rod, where the 10-80-DHPT model uses the powered anode that eliminates the need for the replacement and maintenance, while the anode on 10-50-DHPST model deteriorates over time and needs to be checked regularly and replaced if consumed.

Temperature setting

The temperature can be selected and set on the digital display, where the 10-80-DHPT heat pump has a temperature range from 95 F to 150 F, while the 10-50-DHPST from 95 F to 140 F.

Operating modes

There are four operating modes one user can select, to save, produce more hot water or protect from freezing or unwanted energy loss:

  • The Efficient mode is when the water heater uses the heat pump only, resulting in excellent savings.
  • In the Hybrid mode, the unit uses both technologies which are very useful when the greater recovery is needed, such as in a case of long hot water draws.
  • The Conventional mode is the electric mode when the heating elements are fully engaged while the heat pump is off. This mode is used when the surrounding air temperature is low so as the efficiency of the heat pump and there is no heat to extract.
  • In the Vacation mode, the heat pump electric water heater is protected from freezing, when the user is absent, and the unit is not producing hot water.


Reliance heat pumps are covered by the 10-year warranty on the tank and its parts.

Differences and unique features

The main difference between Reliance heat pumps is the tank size or capacity; the 80-gallon water heater is recommended for homes with up to 5 family members, while the 50-gal unit with the First Hour Delivery of 67.5 gallons, is for homes with up to 4 family members or homes with 4 bathrooms.

The 10-80-DHPT model heats water in the same way as the 10-50-DHPST model, but the energy factor is lower; it is 2.33 when working in the hybrid mode, while the 50-gal unit has the energy factor of 2.78 in the efficiency mode.

The 10-50-DHPST unit utilizes the SmartPort so it can be connected to home management for better temperature control and additional energy savings.

The size of the 80-gal unit is approximately 25" in diameter and 81" in height, making it wider by 3" and 20" taller than the 50-gal unit. The weight is 410 lbs, which is more than two times the weight of the smaller heat pump.
