How the Hubbell Heat Pump Water Heater Works

The Hubbell Model PBX Heat Pump Water Heater uses a small amount of electricity to transfer heat from the air to water. In comparison, traditional electric water heaters use resistive heating elements to directly heat water. The Hubbell Model PBX is significantly more energy efficient compared to a conventional electric water heater because less electricity is required for a heat pump water heater to produce the same amount of hot water a a traditional electric water heater.

Quite simply, a heat pumps works like a refrigerator in reverse. A refrigerator moves heat from inside the refrigerator (making things cold) and transfers that heat energy to the surrounding room. A heat pump water heater on the other hand pulls free and essentially unlimited heat from the surrounding air and transfers that heat to the hot water stored in the tank.

The Hubbell Model PBX Heat Pump Water Heater can pull heat out of air as cool as 40°F, and if it cannot provide enough heating capacity to meet demand, the water heater includes back-up resistive heating elements to ensure the unit provides sufficient hot water. The heat pump process of removing heat from the air and transferring it to the water results in the exhaust of cooler dryer air, with as much as 0.4 gallons per hour of "free" dehumidification provided by the heat pump when the unit is heating water.

Heat Pump Functions

Heat Pump Functions Diagram
  1. The built in fan draws room air into the water heater heat pump compartment and across an evaporator coil, and exhausts cooler and slightly dryer (dehumidified) air.
  2. The evaporator coil captures heat energy in the air and transfers that energy to a specially formulated CFC free refrigerant contained within the evaporator.
  3. The refrigerant changes from a liquid to a gas as it gets warmer.
  4. The refrigerant, now as a warm gas, exits the evaporator and passes into a compressor.
  5. The warm gas is compressed, causing it to become a superheated hot gas and then flows to the heat exchanger.
  6. The heat exchanger transfers heat energy from the superheated hot gas to the cold water from the tank.
  7. The pump circulates cold water from the tank through the heat exchanger resulting in a continuous transfer of heat energy from the superheated gas to the water.
  8. Hot water exits the heat exchanger and is stored in the tank.
  9. The superheated gas condenses back to a liquid and awaits to repeat the process.

Selectable Operating Modes

PBX Mode EconomyThis mode controls the heater such that the heat pump provides essentially all of the heating capacity. This is typically the lowest operating cost mode.

PBX Mode HybridThis mode controls the heater in a way to optimize its efficiency and user experience and is the default setting. This mode operates the water heater such that the heat pump provides the vast majority of heating capacity and automatically switches to electric resistance heater mode only when necessary to meet high demand or to optimize efficiency.

PBX Mode ElectricThis mode controls the heater such that it only heats using the electric resistance heaters and operates as a traditional electric water heater. The heat pump will not operate in this mode.

PBX Mode SuperThis mode controls the heater such that both the heat pump and the electric resistance elements can operate simultaneously. This mode provides the fastest recovery option possible by providing heating capacity from both the heat pump and the electric resistance heaters at the same time.

PBX Mode VacationThis mode prevents the heater from heating (regardless of what mode it is in) as a way to improve efficency during long periods of no usage (i.e. vacation). In this mode the only time the heater will heat is if the unit is in danger of freezing. The user sets the number of days to be in vacation mode (adjustable from 2 to 99 days or Off), and the unit resumes its previous mode of operation at the end of this period.

Temporary Modes

PBX Mode Max HeatSimply pressing one button maximizes heating capacity by temporarily putting the heater into super mode.

PBX Mode Fan OffSimply pressing one button temporarily lowers the fan speed which reduces the airflow and minimizes operating noise. Pressing the button twice turns the fan off for a user adjustable time period.

Installation Requirements

Installed location must be at least a 10' x 10' x 7' room (700 cubic feet of air space). If smaller, there must be louver installed to provide sufficient airflow.
Installed room location must not be cooler than 40°F.
Installed locations with warmer ambient air temperature (i.e. furnace room) provides abundant "free" heat and is advantageous.
The heat pump dehumidifies the air and as a result produces condensate which must be piped to drain or outdoors.
The washable air filter requires periodic cleaning. Frequency depends upon environmental conditions.

Model PBX Specific Questions

Why choose a HPWH versus a standard electric water heater?

HPWH’s are the latest technology in water heating and provide the highest efficiency available for heating water. As a comparison, the Hubbell high efficiency 50 gallon electric water heater is estimated to cost $508 per year to operate, whereas the Hubbell model PBX heat pump water heater is estimated to cost $201 per year, a savings of $307 annually. So, from an operating cost standpoint, the advantage of a HPWH is clear. However, other factors need to be considered when deciding HPWH versus electric water heater. One major factor is the initial total installed cost of the heater, with a heat pump water heater approximately 2-3 times higher cost compared to a traditional electric water heater. Compared to a standard electric water heater a HPWH is a more challenging and therefore more expensive installation, has more restrictions with respect to installation conditions and is newer technology and therefore to a certain degree less proven and more challenging to service. Having said that, a HPWH is by far the most efficient method for heating water and deserves careful consideration if it is right for your application.

What is the difference between a Hybrid and a Heat Pump Water Heater?

These terms are interchangeable and refer to the same type of heater. The term “Hybrid” arose when manufacturer’s combined standard type electric water heaters with a heat pump to create a new type of water heater. This new type of water heater includes both electric resistance heating and heat pump technologies, and therefore the term Hybrid water heater was coined. However, the marketplace is also calling this new type of water heater a Heat Pump Water Heater even though it includes resistance heaters. The only time when a heat pump water heater would not be considered a hybrid is if it did not include any form of electric resistance heater. The Hubbell model PBX water heater is comprised of both resistance heaters and a heat pump system, and therefore is considered a hybrid, although as noted above is also referred to simply as a heat pump water heater

Where can I install a heat pump water heater?

Heat pump water heaters can be installed in a variety of locations, from a garage to a heated utility room. Things to consider include space, sound, cold air, and size/height. For more information, visit Here.

How does a Heat Pump Water Heater (HPWH) water heater work?

The heat pump removes a small amount of heat from the surrounding air, heats the water and moves the cooler air back into the room. The Hubbell model PBX Heat Pump Water Heater produces the same amount of hot water as a traditional electric water heater, but with greater efficiency. Think of the HPWH as a refrigerator working in reverse. Just as a refrigerator removes heat from its enclosed interior and releases the heat into the surrounding kitchen, a HPWH takes heat from the surrounding air and transfers that heat into the water of the tank. These things are normal with a Hubbell HPWH: It is normal for cool air to blow out the vents on the back cover of the water heater. The air is moved through the water heater by a fan located within the heat pump enclosure on the top of the water heater. You will hear the sound of this fan pulling the air through the heat pump system. As the water heater determines the right amount of energy needed to heat the water the fans will change speed and the sound will increase and decrease. For a detailed discussion regarding HPWH’s please go Here.

What type of maintenance does a heat pump water heater require?

Unlike standard electric water heaters, heat pump water heaters use an air filter. These filters need to be cleaned to ensure efficient operation. In addition, a HPWH generates condensate which must be plumbed to a proper drain. This condensate drain may be gravity or pump assisted, and in both cases needs to be periodically inspected and cleaned to ensure proper drainage. Other maintenance needs are similar to standard electric water heaters.

What should I know about Legionella disease?

Legionella is the bacteria responsible for Legionnaire’s Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1977 by the Centers for Disease Control as the cause of an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia. Pontiac Fever is a less severe, non-pneumonia, flu-like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacterium and has been found to exist widely in many surface water sources including lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health. When the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures (105-115°F), stagnant water areas (isolated storage tanks and dead-end piping legs) and ample food sources (sediment, scale, deposits and biofilm). Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaire’s Disease. There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 140°F. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious thermal shock and scalding injuries. As such, many plumbing engineers will specify that the water heater be set to maintain water temperatures at 140°F or higher to reduce the risk of Legionella, but then specify the appropriate mixing valve to ensure safe delivery of hot water to the fixtures. For a more thorough discussion of Legionella please go to here and the following link to the US Department of Labor OSHA information regarding Legionnaires’ Disease OSHA here
