Compared to standard electric heaters, heat pump hot water heaters can produce almost double the amount of hot water against same unit electricity consumption. But before you opt for one to have at your home you can always consider it better to learn a few things on how they work and why investing in them can make better sense.
How they work
The heat pumps hot water systems presently available in the market are actually dependent on refrigerant cycles for moving the heat from one place to another. This is the same basic principle used in refrigeration. The primary difference between a standard electric storage water heater and a heat pump water heater is that the in the former electric energy is directly converted to heat energy while in the later the electricity is used for running a heat pump for extracting heat from the room and delivering it to the water at a higher temperature.
Different types
Depending upon their functionality heat pump hot water heaters presently available can be classified in two categories,
· Self contained and
· Modular
In self contained type of heaters the heat pump unit is integrated with the storage tank directly. But in the modular heat pump hot water systems there is an add-on heat pump connected to a standard water heater of storage type. In both the models, there is a fan for pulling down room air inside the exchanger core and then transferred to the refrigerant using copper coils. As the refrigerant is colder than the air, heat exchange takes place and the heated refrigerant gas is then circulated through the water in the storage tank to heat up the water. Compared to standard electric water heating systems, these heat pump water heaters are more energy efficient and the energy efficiency of the heaters is measured in a unit called ‘coefficient of performance’ or ‘energy factor’.
Investing in these heat pump hot waters is am sensible option as it can give you double the amount of hot water against the same unit electricity consumption.
