Heat Pump for sale.
A heat pump is a special heating system that provides heat energy from a foundation of heat to a target called a "heat sink". Heat pumps are designed to move thermal energy opposite to the direction of natural heat flow by absorbing heat from a cold space and releasing it to a warmer one, and vice-versa. A heat pump uses some amount of external power to carry out the work of conducting energy from the heat source to the heat sink. Find Heat Pump for sale on Ebay!
