Tank water heater assembly and transport assembly
A tank water heater assembly is provided including a tank water heater and a drain pan provided with a sensor holder for mounting a sensor. The sensor holder accommodates a leak detection sensor at predefined distance above an inner surface of a bottom wall of the drain pan. In this way the presence of harmless small amounts of water in the drain pan do not trigger an alarm. A transport assembly is presented for facilitating transportation of the tank water heater assembly to an installation site and subsequent installation. Finally, a method for installation of a tank water heater assembly is provided.
1. A tank water heater assembly comprising:
a tank water heater; and
a drain pan;
wherein the drain pan is made of plastic and is provided with integrally molded support legs on its bottom side,
wherein the support legs include at least a first support leg, a second support leg, a third support leg and a fourth support leg arranged on the perimeter of the drain pan, wherein the support legs are arranged at a distance from each other, the first support leg being arranged at a first distance from the second support leg, the second support leg being arranged at a second distance from the third support leg, the third support leg being arranged at a third distance from the fourth support leg, and the fourth support leg being arranged at a fourth distance from the first support leg, the support legs further including a fifth support leg being arranged in the center of the first support leg, the second support leg, the third support leg and the fourth support leg,
the distance between the support legs making sufficient room for allowing a fork of a forklift to pass below the drain pan and enabling to meet two different fork sizes, wherein the first distance is equal to the third distance, the second distance is equal to the fourth distance and the first distance is larger than the second distance, and
wherein the bottom side of the drain pan is provided with an iso-grid reinforcement structure, the iso-grid reinforcement structure providing a flat design for carrying the load of the tank water heater assembly using a forklift in either of the direction of the second distance and the direction of the fourth distance.
