Heat Pump Hot Water Systems
Heat pumps offer
the most energy-efficient way to provide heating and cooling
in many applications, as they can use renewable heat sources
in our surroundings. Even at temperatures we consider
to be cold, air, ground and water contain useful heat
that's continuously replenished by the sun.
Heat Pump Water Heaters use electricity to move heat from
one place to another instead of generating heat directly.
To heat water for homes, heat pump water heaters work
like refrigerators in reverse. Heat pumps are purchased
as integral units with built-in water storage tanks. Electric
heat pumps are an efficient type of electric storage water
heater that extracts heat from the environment to heat
water. They pay back the extra initial investment more
quickly in larger households.
Heat pumps draw heat from the air and use only about one
third of the energy of a standard electric system and
can be made even more efficient by using a solar preheater.
Electricity is not used to directly heat the water but
to move heat from one place to another. The heat is carried
by a refrigerant.
Compared to conventional electric water heaters, Heat
Pumps are more energy efficient and draw less power.
