1. BASIC OPERATION PRINCIPLE
We
know
from experience, the natural flow of heat, moves from a
higher to a lower temperature source, a heat pump can transfer heat
from a lower temperature source to a higher temperature source with
high efficiency.
The advantage of a heat pump water heater is that it can supply more
heat energy, normally 3
:
1 times than input electricity power by
extracting the heat from ambient atmosphere in a free-of charge way
and transfer to Sanitary Hot Water.
Compared
to a traditional water
heater, such as electric water heater or gas burner water heater, their
efficiency is normally less than 1:1, which means you can dramatically
cut off the bill of family daily SHW by the application of heat pump
water heater, the following examples will show more details.
Power consumption comparison under the same condition to heat 1
ton of water from 15˚C to 55˚C.
