(c) a pump ( 12 );
(d) a bypass conductor ( 10 ) comprising a first end, a second end and an exhaust ( 14 ) comprising at least one opening configured for allowing effluents of said at least one opening ( 16 ) to be pointed in a direction from said exit end of said hot side conductor ( 6 ) to said closed end of said hot side conductor ( 6 ), wherein said first end of said bypass conductor ( 10 ) is adapted to said receiving end of said cold side conductor ( 4 ) and said second end of said bypass conductor ( 10 ) is adapted to said exit end of said hot side conductor ( 6 ) and said exhaust is disposed within said hot side conductor ( 6 );
(e) at least one heat exchanger ( 8 ) comprising a flow valve ( 32 );
(f) an inlet temperature sensor ( 28 ) disposed on an inlet of said at least one heat exchanger ( 8 );
(g) an outlet temperature sensor ( 30 ) disposed on an outlet of said at least one heat exchanger ( 8 ) closest to said exit end of said hot side conductor ( 6 );
(h) a system outlet temperature sensor ( 40 ) disposed on said exit end of said hot side conductor ( 6 ); and
(i) a system inlet temperature sensor ( 38 ) disposed on said receiving end of said cold side conductor ( 4 ),
wherein said receiving end of said cold side conductor ( 4 ) is configured to be connected to a cold water supply manifold, said exit end of said hot side conductor ( 6 ) is configured to be connected to a hot water supply manifold ( 26 ), said pump ( 12 ) is configured to generate a flow through each of said at least one heat exchanger ( 8 ) and whereby when a temperature indicated by said inlet temperature sensor ( 28 ) exceeds a temperature indicated by said system inlet temperature sensor ( 38 ), said flow valve ( 32 ) of said at least one heat exchanger ( 8 ) is configured to be restricted to enable an increased flow from said receiving end of said cold side conductor ( 4 ) to said exit end of said hot side conductor ( 6 ) through said bypass conductor ( 10 ) to temper a flow exiting said exit end of said hot side conductor ( 6 ) and when a temperature indicated by said system outlet temperature sensor ( 40 ) falls below a temperature indicated by said inlet temperature sensor ( 28 ), said flow valve ( 32 ) of said at least one heat exchanger ( 8 ) is configured to be enlarged to enable an increased flow from said cold side conductor ( 4 ) to said exit end of said hot side conductor ( 6 ) through said at least one heat exchanger ( 8 ) to increase the temperature of the flow exiting said exit end of said hot side conductor ( 6 ) and said at least one opening of said exhaust causes said effluents of said at least one opening ( 16 ) to be mixed with a flow within said hot side conductor ( 6 ) to form the flow exiting said exit end of said hot side conductor ( 6 ).

2. The low pressure drop water heating system ( 2 ) of claim 1 , wherein said hot side conductor ( 6 ) further comprises an upper half and a lower half and said exhaust ( 14 ) is configured to be disposed on said upper half of said hot side conductor ( 6 ).

3. The low pressure drop water heating system ( 2 ) of claim 1 , wherein said hot side conductor ( 6 ) further comprises an upper half and a lower half and said exhaust ( 14 ) is an inverted J-shaped exhaust having at least one opening disposed on said upper half of said hot side conductor ( 6 ).

4. The low pressure drop water heating system ( 2 ) of claim 1 , wherein said exhaust ( 14 ) further comprises at least one opening configured for allowing effluents of said at least one opening to be pointed in a direction perpendicular to a direction from said exit end of said hot side conductor ( 6 ) to said closed end of said hot side conductor ( 6 ).

5. The low pressure drop water heating system ( 2 ) of claim 1 , wherein said hot side conductor ( 6 ) further comprises a volume of from about 0.5 to about 2 gallons and said bypass conductor ( 10 ) comprises a tubing of size of from about 0.5 to about 1.5 inches.

6. The low pressure drop water heating system ( 2 ) of claim 1 , further comprising a valve ( 56 ) disposed within said bypass conductor ( 10 ).

7. A low pressure drop water heating system ( 2 ) comprising:
(a) a cold side conductor ( 4 ) comprising a receiving end and a closed end;
(b) a hot side conductor ( 6 ) comprising an exit end, a closed end and a volume of from about 0.5 to about 2 gallons;
(c) a pump ( 12 );
(d) a bypass conductor ( 10 ) comprising a first end, a second end and a tubing of size of from about 0.5 to about 1.5 inches, wherein said first end of said bypass conductor ( 10 ) is adapted to said receiving end of said cold side conductor ( 4 ) and said second end of said bypass conductor ( 10 ) is adapted to said exit end of said hot side conductor ( 6 );
(e) at least one heat exchanger ( 8 ) comprising a flow valve ( 32 ), an inlet temperature sensor ( 28 ) disposed on an inlet of said at least one heat exchanger ( 8 ) and an outlet temperature sensor ( 30 ) disposed on an outlet of said at least one heat exchanger ( 8 );
(f) a system outlet temperature sensor ( 40 ) disposed on said exit end of said hot side conductor ( 6 ); and
(g) a system inlet temperature sensor ( 38 ) disposed on said receiving end of said cold side conductor ( 4 ),
wherein said receiving end of said cold side conductor ( 4 ) is configured to be connected to a cold water supply manifold, said exit end of said hot side conductor ( 6 ) is configured to be connected to a hot water supply manifold ( 26 ), said pump ( 12 ) is configured to generate a flow through each of said at least one heat exchanger ( 8 ) and whereby when a temperature indicated by said inlet temperature sensor ( 28 ) exceeds a temperature indicated by said system inlet temperature sensor ( 38 ), said flow valve ( 32 ) of said at least one heat exchanger ( 8 ) is configured to be restricted to enable an increased flow from said receiving end of said cold side conductor ( 4 ) to said exit end of said hot side conductor ( 6 ) through said bypass conductor ( 10 ) to temper a flow exiting said exit end of said hot side conductor ( 6 ) and when a temperature indicated by said system outlet temperature sensor ( 40 ) falls below a temperature indicated by said inlet temperature sensor ( 28 ), said flow valve ( 32 ) of said at least one heat exchanger ( 8 ) is configured to be enlarged to enable an increased flow from said cold side conductor ( 4 ) to said exit end of said hot side conductor ( 6 ) through said at least one heat exchanger ( 8 ) to increase the temperature of the flow exiting said exit end of said hot side conductor ( 6 ).
