Apparatus for supporting expansion tank
View Patent ↗An apparatus supporting a thermal or hydronic expansion tank in fluid communication via a pipe nipple with a water heater in a water piping system. The supporting apparatus comprises a mounting base adapted to be mounted directly to the water heater. A rack constructed of rigid material is adapted to be secured to the tank. The rack is fastened to the mounting base. The tank is mounted in a vertical orientation on the water heater with the pipe nipple pointing upward or downward. There is sufficient spatial separation of the tank from the mounting base to permit the tank to be insulated or otherwise covered for protecting the tank from the environment.
1. An apparatus supporting a thermal or hydronic expansion tank in fluid communication via a pipe nipple with a water heater in a water piping system, the supporting apparatus comprising:
a mounting base adapted to be mounted directly to the water heater; and
a rack constructed of rigid material adapted to be secured to the tank, the rack fastened to the mounting base,
wherein the tank is mounted in a vertical orientation on the water heater with the pipe nipple pointing upward or downward, and
wherein the mounting base comprises two components permanently joined together, the components comprising a planar flange portion adapted to be fastened horizontally to the top surface of the water heater, and a column member extending perpendicularly and vertically from the planar flange portion, the column member being configured to be connected to the rack, wherein the column member is mounted along the side of the water heater, and
wherein there is spatial separation of the tank from the mounting base, the spatial separation comprising space to permit an outer insulation jacket to cover the tank.
2. A supporting apparatus as recited in claim 1 , further comprising means for securing the tank to the rack.
3. A supporting apparatus as recited in claim 2 , wherein the securing means comprises a flexible band to encircle the tank and secure the tank to the rack.
4. A supporting apparatus as recited in claim 1 , wherein the tank may be mounted in the vertical orientation along the side of the water heater.
5. A supporting apparatus as recited in claim 4 , wherein the column member is adapted to be additionally fastened to the side of the water heater for added stability.
6. A supporting apparatus as recited in claim 1 , wherein the rack comprises a separator for spacing the rack from the mounting base.
7. A supporting apparatus as recited in claim 6 , wherein the separator defines at least one opening for passing a flexible band encircling the tank for securing the tank to the rack.
8. A supporting apparatus as recited in claim 1 , wherein each of the rack and the mounting base define corresponding longitudinally spaced fastener holes allowing for a plurality of relative positions when connected by fasteners.
9. A supporting apparatus as recited in claim 1 , wherein the spatial separation further comprises space to permit the outer insulation jacket of the tank without interference between the mounting base and the outer insulation jacket of the tank.
