Energy conserving system for use with heating and/or hot water systems and the like

Claim 1

Apparatus for providing electrical energy at low consumption and high efficiency for use in heating and/or hot water systems, comprising: single phase motor means powered by an independent single phase a.c. source for driving its output shaft; multiphase electrical generator means having mechanical input means; mechanical means for coupling the output shaft of said motor means to the mechanical input means of said multiphase generator means for generating multiphase output power at the electrical outputs of said multiphase electrical generator means, wherein the electrical outputs of said multiphase electrical generator means are electrically isolated from said independent single phase a.c. source; multiphase load means for converting electrical energy into heat for heating a fluid, said load means being electrically isolated from said single phase a.c. source and having ratings matching the output power ratings and operating frequency of said multiphase electrical generator means wherein the electrical isolation of said multiphase electrical generator means and said single phase source permits the selection of an electrical generator having an operating frequency which is different from the operating frequency of the single phase a.c. source to optimize the match between the multiphase electrical generator means and the multiphase load means regardless of the operating frequency of the single phase a.c. source; first switch means for normally maintaining said multiphase load means electrically disconnected from the electrical outputs of said multiphase electrical generator means; said switch means being responsive to said multiphase electrical generator means reaching a predetermined operating condition for electrically connecting said multiphase load means to said multiphase electrical generator means thereby enabling said single phase motor means and said multiphase electrical generator means to reach optimum operating conditions at a more rapid rate; thermostat means for sensing the temperature level of the fluid being heated; and second switch means responsive to said thermostat means for electrically disconnecting said motor means from said a.c. soruce when the fluid being heated reaches a predetermined level and for electrically reconnecting said motor means to said a.c. source when the temperature level in the fluid being heated drops below said predetermined level.
