Tankless water heater assembly

A tankless water heater assembly designed to heat a continuous supply of water, said assembly comprising:

• a) an entrance chamber connected in fluid receiving relation to a water inlet and including a control switch assembly including a flow switch mounted therein,
• b) a heating means adapted for heating water and including a first heating chamber having an elongated configuration and a second heating element mounted therein and a second heating chamber having an elongated configuration and a second heating element mounted therein,
• c) said second heating chamber and second heating element disposed downstream of said first heating chamber and first heating element and said second heating chamber including a water outlet mounted therein,
• d) a plurality of ports interconnected between said first and second heating chambers in spaced relation to one another and adapted to transfer water between said first and second heating elements,
• e) a path of flow of water defined successively by said water inlet, said entrance chamber, said first heating chamber, said plurality of ports, said second heating chamber and said water outlet,
• f) said plurality of ports comprising two ports disposed in spaced relation along a length of both said first and second heating chambers, a first of said two ports having a proportionately smaller transverse dimension than a second of said two ports and adapted to pass proportionately less water between said first and second chambers than said second port,
• g) said first port being disposed upstream of said second port along said path of flow of water and in closer spaced relation to substantially commonly disposed proximal ends of said first and second heating chambers than said second port and said second port being disposed in closer spaced relation to substantially commonly disposed distal ends of said first and second heating chambers than said first port,
• h) sensing means mounted along said path of flow and adapted for sensing temperature of water passing through said heating means, and
• i) control means operatively connected to said sensing means and said control switch assembly and adapted for regulating activation of an electrical current flow to said heating means dependent on flow rate and temperature of water passing along said path of flow of water.
