Apparatus and method for heating water

Abstract

It is an object of the subject matter to disclose a water heating device, comprising a vaporizer for vaporizing refrigerant and a compressor for compressing the vaporized refrigerant. The device also comprises a shell; such as a condenser and a volume reducing member positioned within the shell. The member is configured to reduce the cross section area of the volume in which water is heated in the shell. The device may also contain a refrigerant coil positioned adjacent to the volume in which water is heated in the shell; the refrigerant coil contains a refrigerant material received from the compressor, said refrigerant material heats the water in the volume in which water is heated in the shell.

         2 . The device according to  claim 1 , wherein the water is heated in the condenser in a volume between the shell and the volume reducing member. 
     
     
         3 . The device according to  claim 1 , wherein the heated water flows in a siphon-like flow between the water heating device and a water storage tank. 
     
     
         4 . (canceled) 
     
     
         5 . (canceled) 
     
     
         6 . The device according to  claim 1 , wherein the volume reducing member is positioned within the shell to provide for local heating of water in a volume adjacent to side walls of the condenser, between the reducing member and the sidewalls. 
     
     
         7 . The device according to  claim 1 , wherein the device is pump-less. 
     
     
         8 . A method of producing hot water, comprising:
 obtaining a heat pump system comprising a condenser having a water inlet, a water outlet, a shell and a refrigerant coil, said condenser is connected to a water storage tank and positioned outside the water storage tank;   disposing a member positioned within the condenser, said member is configured to reduce the cross section area in which water is heated in the condenser;   creating a siphon flow between the condenser and a water storage tank.   
     
     
         9 . The method according to  claim 8 , comprising allowing the water being heated and rising along the refrigerant coil in the condenser to rise in a siphon-like manner. 
     
     
         10 . A method for heating water at a condenser, the method comprising:
 obtaining a condenser connected to a water storage tank and located outside the water storage tank, wherein water flows between the condenser and the water storage tank;   regulating the flow rate of water entering the condenser;   providing water at a desired temperature from the condenser to the water storage tank according to the regulated flow rate.   
     
     
         11 . The method according to  claim 10 , wherein the water flow between the condenser and the water storage tank using a siphon flow. 
     
     
         12 . The method according to  claim 10 , wherein regulating the flow rate of water is performed at the outlet of the water storage tank. 
     
     
         13 . (canceled) 
     
     
         14 . (canceled)
