Heat Pump Water Heaters:

How They Work and How

They Cut Your Spending

Water heaters have become an important part of many

households, especially those that are situated in areas with

generally cold weather. Although there are still households that

heat water the conventional way, many have attested to the

numerous benefits of water heaters, and this technology

continues to play an essential role in homes and businesses.

Heat pump water heaters (HPWHs) in particular have attracted

the attention of many homeowners because of their distinct

features. Below are some of their well-received features that

should give you an idea of their unique advantages.

Unlike conventional water heaters, HPWHs make use of electricity

to transfer heat from one place to another. Standard water

heaters generate direct heat, whereas HPWHs use a heat pump

for heat generation. After harnessing heat from the air of their

surroundings, HPWHs then transfer this heat energy to the water

tank that holds the water supply. With the efficiency of this

process, HPWHs remain a low-cost and effective water heating

technology.

Operating Modes

HPWHs can be operated under various modes, namely, economy

mode, hybrid mode, heater mode, and vacation mode. With the

varying needs and demands of users with regard to water heating,

these modes of HPWHs give users enough freedom to choose the

one that works best for their daily activities.

The economy mode is best

selected when you seldom

require hot water. Your energy

efficiency increases under this

mode because it heats up water

with only the heat pump.

The hybrid mode is similar to the economy mode, except that it

also uses sustained heat. This energy-saving mode is the

preferable choice when the demand for hot water throughout the

day is consistent but not high.

Economy Mode

Hybrid Mode

Considered as the least energy-saving mode, the heater mode is

ideal for homes whose daily demands for hot water are

consistently high. This mode only uses the heater’s electric

element to heat water, thereby consuming more energy than the

economy mode.

Although not available in all models, this mode puts your HPWH

to “sleep” while you are out of the house. Whether you are

heading out to the office or going on an extended vacation, the

sleep mode of HPWHs allows you to save maximum energy, as

the system only resumes its functions when you switch this mode

off upon your return.

Choosing the right HPWH need not be difficult, especially when

you have adequate knowledge of how they actually work. With

the overview presented here, you can begin taking the next steps

to purchasing an HPWH for your home.
