A pool and spa water heater has a base and an enclosure coupled to the base. The enclosure includes a pair of curved, "shell-like" enclosure components coupled to the base by an overlapping attachment device, e.g., a tongue-and-groove device. The enclosure components may be removed from and attached to the base by moving each component laterally away from or toward the base. The new heater has a platform atop the enclosure for mounting a control panel. The platform and the support device to which the platform is mounted are cooperatively configured so that the platform may be indexed to any one of several positions with respect to the support device and the enclosure. Thus, after placing the base during installation, the control panel may be optimally and independently positioned with respect to the base.
In a pool and spa water heater having a base, an enclosure coupled to the base, a cold water inlet port and a hot water discharge port mounted to the enclosure, and a firing unit in the enclosure for transferring heat to water flowing from the inlet port to the discharge port, the improvement wherein:
