Dry element water heater

A water heater assembly, the water heater assembly comprising:

• (a) a housing having an inlet, an outlet and a channel extending between the inlet and outlet for passing water through the channel;
• (b) a first electrical heating element conduit disposed within the channel of the housing and extending between the inlet and outlet;
• and
• (c) a first heating element removably disposed within the conduit, the heating element conduit surrounding the heating element for sealing the heating element from direct contact with the water while permitting heat transfer between the heating element and water flowing about the heating element conduit, further comprising a bypass conduit extending between the inlet and outlet of the housing to divert a predetermined amount of water entering the inlet to pass through the water heater assembly without contacting the heating element conduit.

A water heater assembly comprising:

• (a) a tubular housing having an inlet, an outlet and a channel extending between the inlet and outlet for passing water through the water heater assembly;
• (b) a plurality of electrical heating elements disposed within the channel and extending between the inlet and outlet of the housing, each heating element being coaxially received within a tubular element conduit for sealing the heating element from direct contact with the water while permitting heat transfer between the heating elements and the water flow about the element conduits;
• and
• (c) a water bypass assembly disposed within the channel and extending between the inlet and outlet of the housing, the bypass assembly providing a sealed passage between the inlet and outlet of the housing to divert a predetermined amount of water entering the inlet to pass through the housing without contacting the heating element housing.

A water heater assembly, comprising:

• (a) a tubular housing having an inlet, an outlet and a channel extending between the inlet and outlet;
• (b) first and second end caps releasably fastened to the inlet and outlet respectively each end cap having a sealed end and a hole extending through and off the center of the sealed end;
• (c) a plurality of heating element conduits extending between the inlet and outlet, each heating element conduit being positioned below each hole of the end caps;
• (d) a plurality of electrical heating elements removably disposed within the conduits;
• and
• (e) at least one seal mounted on the heating element conduits to seal the heating element from direct contact with the water while permitting heat transfer between the enclosed heating element and water flowing about adjacent the heating element conduit, further comprising a water bypass assembly extending between the inlet and outlet of the housing to divert a predetermined amount of water entering the inlet to pass through the water heater assembly without contacting the heating element conduit.

A water heater assembly, the water heater assembly comprising:

• (a) a housing having an inlet, an outlet and a channel extending between the inlet and outlet for passing water through the channel;
• (b) a first electrical heating element conduit disposed within the channel of the housing and extending between the inlet and outlet;
• (c) a first heating element removably disposed within the conduit;
• and
• (d) at least one elastomeric seal mounted on and sealed to the heating element conduit to seal the heating element from direct contact with the water while permitting heat transfer between the heating element and water flowing about the heating element conduit.
