Apparatus for cleaning a heat exchanger

Abstract

An apparatus for cleaning interior deposits and debris from a potable water heat exchanger, the apparatus having a first connector and a second connector. The first connector is mated with an outlet of a pump capable of pumping compressed fluid into the potable water heat exchanger without contaminating the compressed fluid and potable water. The second connector is mated with a fitting of the potable water heat exchanger. At least one connector having an associated valve.

1 . An apparatus for cleaning interior deposits and debris from a potable water heat exchanger, comprising;
 a first connector and a second connector;   the first connector being mateable with an outlet of a pump capable of pumping compressed fluid into the potable water heat exchanger without contaminating the compressed fluid and potable water;   the second connector being mateable with a fitting of the potable water heat exchanger; and   at least one connector having associated valve means.   
     
     
         2 . The apparatus as claimed in  claim 1 , wherein the potable water heat exchanger is a secondary heat exchanger of a combination boiler. 
     
     
         3 . The apparatus as claimed in  claim 1 , wherein the first and second connectors have a length of conduit there between. 
     
     
         4 . The apparatus as claimed in  claim 1 , the preceding claims, wherein the second connector comprises a valve. 
     
     
         5 . The apparatus as claimed in  claim 3 , wherein the first connector comprises a first valve that allows fluid to flow in a direction from a first end of the conduit to a second end of the conduit. 
     
     
         6 . The apparatus as claimed in  claim 1 , wherein the first connector is mated with an outlet connector of the pump, wherein the pump is an electrically driven pump. 
     
     
         7 . The apparatus as claimed in  claim 1 , wherein the first connector is mated with an outlet connector of the pump, wherein the pump is a battery driven pump. 
     
     
         8 . The apparatus as claimed in  claim 1 , wherein the pump includes a power supply, wherein the power supply uses either a 12 volt direct current source or a 240 volt alternating current source. 
     
     
         9 . The apparatus as claimed in  claim 1 , wherein the pump is a non-oil lubricated pump. 
     
     
         10 . The apparatus as claimed in  claim 1 , wherein the second connector is mated with a fitting of the potable water heat exchanger. 
     
     
         11 . The apparatus as claimed in  claim 1 , further comprising a potable water heat exchanger system operably associated therewith. 
     
     
         12 . The apparatus as claimed in  claim 1 , further comprising a combination boiler system operably associated therewith. 
     
     
         13 . A method of urging a turbulent fluid flow through a potable water heat exchanger, comprising the steps of:
 pumping a volume of uncontaminated pressurized fluid through water inside the potable water heat exchanger for creating a turbulent flow of water and fluid through the potable water heat exchanger for removing contaminants from the inside surface of the potable water heat exchanger.   
     
     
         14 . The method as claimed in  claim 13 , wherein the pumping step uses an electricity or battery operated pump. 
     
     
         15 . The method as claimed in  claim 13 , further comprising the step of opening a faucet, tap or plumbing fitting connected downstream of the potable water heat exchanger. 
     
     
         16 . The method as claimed in  claim 13 , further comprising the step of urging a turbulent fluid flow through the potable water heat exchanger of a combination boiler.
