For efficient cooling and heating installation we can create a water heat exchanger, submerged at the bottom of the well vertebral and radiator / water heater before entering clean air to the recuperator.
Kwa baridi ufanisi na ufungaji inapokanzwa tunaweza kujenga joto maji exchanger, iliyokuwa chini ya heater vizuri mgongo na bomba / maji kabla ya kuingia hewa safi kwa recuperator .
