A heating system combines a heat source for applying heat energy to a supply of heat transfer fluid including a polyol having five or less pendant hydroxyl groups and a polydimethylsiloxane and a pump that moves the heat transfer fluid through conduits to a heat exchanger. In one configuration, the heating system has a primary circuit including the heat source, delivery line, pump, heat exchanger and return line, and a sub-circuit including a bypass line interconnecting the delivery line and the return line to provide a flow path bypassing the heat source. The sub-circuit includes the bypass line, a portion of the delivery line, the pump, the heat exchanger, and a portion of the return line. Control valves and a control mechanism direct the flow of fluid between the primary and sub-circuit. The heat transfer fluid is a blended mixture of 5-15% glycerin, 20-40% propyl glycol and 45-75% silicone.

A heating system comprising: a heat source for applying heat energy to a supply of heat transfer fluid;conduit to carry the heat transfer fluid to and from said heat source, said conduit including a delivery line in which the heat transfer fluid moves away from said heat source and a return line in which the heat transfer fluid is returned to said heat source;a heat exchanger in flow communication with said conduit to extract heat energy from said heat transfer fluid;a pump to move said heat transfer fluid through said conduit; andsaid heat transfer fluid including a polyol having five or less pendant hydroxyl groups and a polydimethylsiloxane. 8. The heating system of claim 7 wherein said heat source comprises: a heating element for generating heat energy for absorption by said heat transfer fluid; anda tank for holding a supply of said heat transfer fluid, said tank being less than ten gallons in size. 9. The heating system of claim 8 wherein said tank is less than six gallons in size. 10. The heating system of claim 8 further comprising: a primary circuit including said heat source, said delivery line, said pump, said heat exchanger, and said return line;a sub-circuit including a bypass line interconnecting said delivery line and said return line to provide a flow path bypassing said heat source, said sub-circuit including said bypass line, a portion of said delivery line, said pump, said heat exchanger, and a portion of said return line;control valves in each of said delivery line, said return line and said bypass line to control the flow of heat transfer fluid between said primary circuit and said sub-circuit; anda control mechanism connected to said control valves for selectively controlling the operation of said control valves in response to a predetermined condition. 11. The heating system of claim 7 wherein said heat transfer fluid comprises: from 25% to 55% by volume of one or more polyols having five or less pendant hydroxyl groups; andfrom 45% to 75% by volume of polydimethylsiloxane. 12. The heating system of claim 11 wherein said polyol having five or less pendant hydroxyl groups comprises: from 5% to 15% of glycerin; andfrom 20% to 40% of propylene glycol,wherein said glycerin and said propylene glycol form a blended glycol component. 13. The heating system of claim 12 wherein said polydimethylsiloxane is added to said blended glycol component to form said heat transfer fluid.
