Air Source Water Heater

Air source water heater system

( Air source heat pump) is made up of a water storage tank and a heat pump. The heat pump is either mounted on top of, or adjacent to, the water storage tank. The heat pump consists of a condenser located around the outside of the water storage tank, a compressor and an evaporator.
An air-source heat pump can provide efficient heating and cooling for your home, especially if you live in a warm climate. When properly installed, an air-source heat pump can deliver one-and-a-half to three times more heat energy to a home compared to the electrical energy it consumes. This is possible because a heat pump moves heat rather than converting it from a fuel, like in combustion heating systems.
Work Principle:

Like an air conditioner in reverse cycle, the heat pump works by absorbing heat from the air into the refrigerant gas within the evaporator. The compressor increases
the pressure and temperature of the gas, and sends it through the condenser which is located in the water tank casing. Here heat energy is transferred to the water, the gas cools and then flows back to the evaporator in a continuous cycle.
Heat pumps do not require direct sunlight, and therefore produce hot water using the same method rain, hail or shine. A heat pump can produce ample hot water for any household situation and has the added advantage of using approximately one-third of the electricity of an electric storage hot water system.
Air source water heater is usually used in the places of family house, bathing spot and hotel.
Example:
Water heating in a residence varies with family size, but a family of four may use an average of 60 gallons per day. This would require 12 kWh per day of electric resistance (EF of 0.86) water heating (from 55^oCF to 120^oCF). An exhaust air heat pump water heater rated with an EF of 2.5 would provide the same amount of hot water for 4.8 kWh/day - a savings of 2,628 kWh/year. Assuming an electricity cost of $0.10/ kWh, savings in annual hot water heating would be $262. Assuming an installed cost for an exhaust air heat pump water heater to be $1,500, the simple payback would be $1500/$262 or 5.7 years.
If you are replacing a failed water heater, assuming a cost premium of $1,200 for nstalling an exhaust air HPWH rather than a conventional electric water heater, the simple payback would be 4.6 years.
