Heat Pump vs Solar
What Is an Air to water Heat pump? An air to water heat pump is an energy efficient product that typically draws 25 to 30% heat – hence the terminology “Reverse Cycle Heating” ELECTRIC HEAT OPERATION The energy is forced through an electrical resistance element which then rejects this heat into … Read Here
