If the ground loop temperature falls to zero the heat pump will not work as no heat is available?!?
Not true, zero degrees Celsius is simply the freezing point of water. Absolute zero is the temperature where no heat exists, this is minus 273°C. Therefore even at zero degrees, the heat pump will extract useful heat. Ground source heat pumps will work down to a ground loop temperature of minus 10°C. Ground source heat pumps are simple, well-proven machines that can provide your entire central heating and hot water requirements. By transferring low-grade heat from a ground heat collector to high-grade heat, very high efficiency (coefficient of performance) can be achieved. This type of heat pump can supply over 4 Kilowatts of heat for each one-Kilowatt consumed. The compressor, which is driven by an electric motor, compresses the refrigerant to a high temperature, high-pressure gas. This gas then passes into the condenser at about 100°C. The water from the radiator system is pumped through the condenser; this is of fully welded stainless steel construction. When this water cools the ho
