Abstract:
1. A water heater securable to a vertical surface, comprising: a tank housing having a first end, a second end, a middle spaced equidistantly between the first end and the second end, an internal chamber with a curved inner sidewall and a central tank axis, the tank housing securable to the vertical surface in one of a horizontal orientation, to orient the central tank axis horizontally, and a vertical orientation to orient the central tank axis vertically; one or more electrically powered heating elements coupled to the first end of the tank housing to extend from the first end and into the internal chamber for heating water received within the internal chamber, the one or more electrically powered heating elements being connectable at terminals disposed exterior to the internal chamber to a current source; a water inlet line having a first longitudinal axis parallel to the central tank axis, the water inlet line connectable at a first end to a water source and extending at a second end from outside the tank housing through an inlet port in fluid communication with an upper portion of the internal chamber of the tank housing to introduce water supplied from the water source into the internal chamber of the tank housing for heating by the one or more electrically powered heating elements; a water outlet line exterior of the internal chamber to remove water displaced from the internal chamber by water introduced into the internal chamber of the tank housing, the water outlet line extending from the tank housing and fluidically connected to the internal chamber of the tank housing, the water outlet line having a second longitudinal axis parallel to the first axis; a first outlet port extending through the curved inner sidewall between the water outlet line and the internal chamber, the first outlet port longitudinally between the middle and the second end of the tank housing; a second outlet port extending through the curved inner sidewall between the water outlet line and the internal chamber, the second outlet port longitudinally between the first outlet port and the first end of the tank housing; a first cap connected to the one or more heating elements; a second cap connected to the second end of the tank housing; a sealing element between the second cap and the tank housing; wherein the first water outlet port and the second water outlet port are between a first plane intersecting and parallel to the first longitudinal axis and the second longitudinal axis and a second plane parallel to and spaced a distance from the first plane and intersecting the central tank axis; wherein the water inlet line intersects a third plane, the third plane intersecting and parallel to the first longitudinal axis and the central tank axis; and wherein the water outlet line intersects a fourth plane angled less than ninety degrees from the third plane, the fourth plane intersecting and parallel to the second longitudinal axis and the central tank axis.
