A Hi Rise Water Source Heat Pump is a high-efficiency HVAC system that uses natural water sources, such as oceans, lakes, rivers, and bays, to transfer heat energy into buildings. By taking advantage of naturally occurring temperature differences between different water sources, this system can provide significant energy savings compared to traditional air conditioning and heating systems. In addition to being more energy efficient, it also requires minimal maintenance, making it an ideal choice for commercial applications. The official business definition of Hi Rise Water Source Heat Pump is “a type ofenergy-efficient heat pump used to draw energy from ocean, lake, river or bay water as a means for heating and/or cooling a building.”
