AO SMITH Integral Heat Pump Water Heaters extract renewable energy stored in the air to heat water. Heat Pumps are not dependent on weather and operate throughout the year even during long winter nights.  With high efficiencies, payback on an AO Smith can be very quick.

Unobtrusive, easy to install and cheap to run, an AO SMITH Integral Heat Pump Water Heater is a smart way to provide hot water for the home. The only energy used by an AO SMITH is electricity to power the pumps - electricity that delivers between two and four times its value in heat output.

AO SMITH Integral Heat Pump Water Heaters are air-source models.  Air-source heat pumps extract heat energy stored in the air.  They operate like a refridgerator in reverse, transferring low temperature energy to a refrigeration loop, compressing the refrigerant to high temperatures, and transferring this heat to heat water.

AO SMITH Integral Heat Pump Water Heater is an impressive new model, containing an 80 litre, and 180 litre, 300 litre or 455 litre patented glass-lined hot water cylinder integrated into the unit.  An AO SMITH Integral Heat Pump Water Heater also makes conversions from gas water heating simple, easy and affordable.
