Consider heat pump hydronic heating and cooling for your energy efficient all-electric home. This means that passive cooling conserves energy particularly well, as the heat pump itself is not in operation – only the circulating pump and control system are. When we talk about cooling systems, most people think of air-conditioning. It also reduces greenhouse emissions, whilst improving indoor air quality and comfort. A geothermal system is made up of only two parts: ground loops and a heat pump. A major objective of the HPF is to raise awareness of the low carbon potential of heat pumps: heat pumps employ heat transfer instead of combustion and therefore issue no CO 2, or anything else on site. Draughts and noise can be kept to a minimum by positioning the fan coils in appropriate locations. This valve is the component responsible for changing the direction refrigerant moves through the heat pump, and that determines if the heat pump is in heating or cooling mode. Why is a heat pump called a heat pump? Newer models of air-source heat pumps use inverter technology on its rotary compressor. On an existing property the ground will need digging. This is due to the installation of the pipes under the ground. Heat Pump air conditioning is perfect for winter warmth & summer cooling - all at the touch of a button. Heating and Cooling With a Heat Pump Publication produced by Natural Resources Canada's Office of Energy Efficiency.
