Natural or propane gas feed auxiliary electric generating system for boilers or furnaces

Abstract

A natural or propane gas fed auxiliary electric generating system is brought to actuation to continue operating the pump in a residential, office building or motel/hotel environment whose boiler operates from the natural gas or propane fed source in the event the electric power otherwise operating the pump is lost or falls below a predetermined threshold.

1 . A residential, office building or hotel/motel structure hot water heating system comprising:
 a natural gas or propane fed hot water boiler or furnace heater;   an electrically operated pump coupled to said heater for circulating heated water throughout said structure; and   an auxiliary generator coupled to the natural gas or propane feed lines for said heater to continue to operate said pump upon the detection of electric power supplied to said pump from electrical supply lines connected to said structure being below a predetermined threshold.   
   
   
       2 . The hot water heating system of  claim 1 , also including a battery energizing source of power to switch said auxiliary generator to an operating mode upon detection of the supplied electrical power being below said predetermined threshold. 
   
   
       3 . The hot water heating system of  claim 2  wherein said battery energizing source switches said auxiliary generator to an operating mode upon detection of a loss of electrical power supplied to said pump. 
   
   
       4 . The hot water heating system of  claim 2  wherein said pump distributes circulating water through one of hot water tubing or baseboard units of said structure.
