Abstract: A heating system uses a dynamic thermal stabilizer for receiving, mixing, holding and outputting a circulating heat exchange liquid in a fashion similar to the use of a flywheel in the mechanical arts. Liquid is returned to the dynamic thermal stabilizer from both an input heat exchange unit and an output heat exchange unit. A two pump system affords a simple tee fitting arrangement that provides room air heating by directly using hot liquid either from the dynamic thermal stabilizer or directly (and at higher temperature) from the input heat exchange unit itself to automatically achieve an additional boost of room heat using higher temperature liquid. The system can also provide initial short draws of domestic hot water from the dynamic thermal stabilizer alone or long draws of hot water by using the input heat exchange unit as a further source of heat input.
