Trusted technologyA heat pump heatingsystem consists of 3components: the heatsource, the heat pump itselfand a heat distribution andstorage system.Heat pumps are able toproduce more energy thanthey consume by using theconventional refrigerationcycle to absorb heat fromthe environment and raiseit to a suitable level forheating.Using nature’s energy efficientlyHeat pumps are among the most efficient heatingand hot water systems available today. Approximately75% of the energy needed for heating comes fromthe environment. This means that for every 1kWh ofelectricity used to power the heat pump compressor,between 3 and 4 kWh of heating energy are produced,giving the heat pump an efficiency of 300-400% orhigher.The heat pump’s “efficiency” is known as it’s “Coefficientof Performance” (CoP). This is simply a ratio betweenthe proportion of the total energy supplied that can beextracted from the environment and the amount suppliedby electricity to run the heat pump compressor. Thehigher the CoP, the more “free” environmental energythe heat pump is using!12Sourcefrom Air or Ground 75%SourceNational Grid 25%1234536EvaporatorHeat PumpCondenser46100%75% of the energy is taken from the environment i.e the air orground and transfered to the heat pump.25% of the energy is sourced from the national grid in the normalway of supplying your electricity. This is used to operate the heatpump but with very low consumptionThe energy from the air or ground is transfered to the refrigerantinside the heat pumps evaporator. This causes the temperature ofthe refrigerant to rise and change state from liquid to gas.The refrigerant gas is then compressed, using an electrically drivencompressor, reducing its volume but causing its temperature to risesignificantly.A heat exchanger (condenser) then extracts the heat energy from thehot refrigerant to heat water for central heating, underfloor heatingor domestic hot water.After giving up its heat energy the refrigerant turns back into a liquidand is able to absorb energy from the environment, allowing thecycle to begin again.5Built to last241Powerful, quiet, safe and reliable. The “heart” of theheat pump is the Copeland scroll compressor, providinghigh levels of efficiency, reliability and low noise operation.13234Always in control. The WPM heat pump managermonitors, regulates and controls the entire system toensure optimum performance and efficiency for heating,domestic hot water and where applicable, cooling.Evaporator. Large surface area plate heat exchangersallow for efficient heat transfer of energy from theenvironment. They are compact, efficient and reliable.Insulated casing. Sound insulation around the insidesof the heat pump casing reduce operating noise to aminimum.Trusted technology7
