Reliance Heat Pumps 
Review and Buying Tips

Explore the best features of the Reliance heat pump for your comfortable and money-saving water heating. See how advanced engineering increases the efficiency for the Energy Star approval and provide a variety of settings for different hot water demand.

Reliance heat pump

The Reliance heat pump is the water heater that combines two technologies; heat pump and electric. This is one of the most powerful electric units from Reliance that is also the only Energy Star approved model in this group. While it is mainly recommended for homes in mild climates, it can also be used in extreme environments as long as it is not exposed to freezing temperatures.

There are two models available, larger with the 80-gallon tank and smaller with 60-gallon tank size. Both models use the 850-watt compressor, lower heating element of 2000 Watts and upper of 4500 Watts.


The innovative design allows Reliance heat pumps to work more efficiently and perform better than the electric models with the same capacity. The heat pump technology is what makes it unique, as it uses the heat from the environment to increase the temperature of water, saving energy and money.

As other heat pumps, Reliance model is also expensive, and it requires a high initial investment, but according to the manufacturer, the payback period is in less than three years.

As opposed to most standard water heaters, Reliance heat pump water heater (HPWH) is equipped with the powered anode rod, which benefits you by prolonging the heater’s life and eliminating the need for replacement, since the anode does not deteriorate over time.

Operating modes

The main features include easy-to-use touchpad to adjust and monitor the temperature, set and change the heating mode and check other info. The water temperature can be set in the range from 95 to 150 F.

The touchpad allows you to set one of the four heating modes:

The Efficient mode uses the heat pump only for maximum performance. The energy factor in this mode can reach a maximum value of 2.3 and 2.4. In this mode, the HPWH uses half the electricity than needed to operate the comparable sized electric unit. The elements are used only if the temperature of the surrounding air drops below 45 F or above 109 F.

The Hybrid mode combines both technologies where the main focus is on the heat pump operation while the electric heating elements are turned on only if the heater requires additional power. This is the default and recommended mode that ensures high energy efficiency and reduced recovery time.

The Conventional mode allows only heating elements to operate while the heat pump is turned off. Since the heat pump uses the surrounding heat to boost efficiency, the extremely cold weather might sometimes prevent the unit from using it. This is the least efficient mode.

The Vacation mode is used in a case of the extended absence, and the water heater works with its minimal energy, protecting the unit in a case of freezing. The temperature of the water is held at approximately 60 F.

The best locations for heat pump installation are basements, garage and utility rooms, together with the furnace so that it can take advantage of the higher temperature of surrounding air. The heat pump comes with the 10-year warranty.
