ABSTRACT:
A fluid circulating system includes a thermal differential engine having a pair of expansion-contraction vessels each containing an expansion component expansible with heat for discharging fluid to a delivery line when heated and drawing fluid from a return line when cooled. Heated water is supplied alternatively to the pair of vessels to circulate the fluid through the delivery and return lines. The pair of expansion-contraction vessels are identical in volume and other characteristics and have multiple ports connected to anti-convectional valves and change-over valve.
