Just looking for opinions on using furnace oil tanks for a pressurized water storage system. I have access to two relatively new 490 Imp Gal tanks. They are cylinders with a 48" diameter by 72" long with stands welded to the tanks and are heavy gauge steel designed for exterior installation. I was thinking of installing them in tandem,side by side, on their ends due to space limitations. I know propane tanks seem to be favoured for this but used tanks are just not available in my area. All opinions are welcome and thanks in advance. Oh, the storage will be located in an addition to my boiler building about 60 feet from the house and will be able to be insulated to any level required. The boiler is a Econoburn 150 currently running without storage.
