Toyotomi Air-to-Water Heat Pump Systems are a cost-effective, energy-efficient, and environmentally friendly method of providing ambient temperature to your house. Knowing that the use of natural gas for heating purposes will be banned in near future, an air-to-water heat pump is a great alternative. In simple terms, the air-to-water pump uses ambient air to heat water and then distributes that heat through a house, usually through radiant floors or a radiator. Air-to-water heat pumps make 1.5 up to 4 times more heat energy than the electrical energy the pump consumes. Air-to-water heat pumps are extremely effective at providing heat or cooling and cut carbon emissions by half.
