18. ncerning use of the appliance by a person responsible for their safety Children and animals should be supervised to ensure that they do not interfere with the appliance How Does The Heat Pump Module Work A heat pump uses complex thermodynamic principles to extract energy from ambient air and transfer this energy to water that is in contact with the unit s immersed heat exchanger The heat pump s operational principles are similar to those used in a normal domestic refrigerator except in reverse In a refrigerator heat energy is drawn from inside the refrigerator making things cold concentrated by the compressor then dissipated to the atmosphere via the condenser coil located on the back of the refrigerator cabinet In a Radiant Heat Pump system outside air is drawn into the unit and across an evaporator coil by a fan The evaporator coil captures the energy in the air and transfers that to cold liquid refrigerant contained inside the evaporator causing the refrigerant to increase in temperature and evaporate into a warm gas The warm gas on exiting the evaporator passes into a compressor where compression causes the temperature of the gas to increase further becoming a superheated hot gas The superheated gas is pumped from the compressor to a water immersed condenser coil where it gives up its heat energy to the water When the superheated gas gives up energy it condenses back to a liquid and on exi
