A thermal engine arrangement comprising a series circuit charged with a vaporizable refrigerating medium, thermal fluid including a storing and preheating tank, an evaporator connected to the storing and preheating tank, a hood enclosing the storing and preheating tank and evaporator directly exposed to the heat of the air and to solar radiation defining a common heating chamber for the storing and preheating tank and evaporator, a thermal engine connected to the evaporator driven by evaporated thermal fluid from the evaporator, a condenser connected to the thermal engine for receiving spent thermal fluid therefrom, a collector tank connected to the condenser for receiving condensate therefrom and a condensate pump connected between the collecting tank and storing and preheating tank for transferring condensed thermal fluid from the collector tank to the storing and preheating tank. Said condenser and collecting tank being located beneath the surface of the ground in direct heat transfer with the ground. Said condenser being adapted to be selectively connected to the heat receiving side of a heat pump. And selectively operable means for heating the thermal fluid.
