The swimming pool in Moulins, France, is equipped with a geothermal heat pump on water table, which provides the heating (air and water) and dehumidification. EDF R&D ensures the
energy monitoring of this particularly powerful installation. From 2008 to 2012, the heat pump produced, on average, 3311MWh ch/an for hot average costs of 17.6€/MWh(*); the cost of maintenance represents an increase in cost of hot MWh of 6%, or 1.08€/MWh hot produced.
It should be noted that if the heating had been produced by a boiler room gas, it would have been at a cost of 44€/MWh. Thanks to the heat pump, the CO2 rejections are reduced by
81%. The geothermal heat pump required an over-investment of 209k€ compared to a boiler room gas heater; the annual economy generated is on average 87k€, yielding a 3 years
