Off-peak tank not reheating
Freeloader tanks run on a controlled off-peak tariff. A cold tank in the morning can be a failed element or simply the off-peak circuit not being energised — check the switchboard before assuming the worst.
A workhorse tank system found in many older Hobart homes. We keep common Vulcan parts on hand.

Vulcan is a long-running Australian storage brand, part of the Rheem group, found in many older Hobart homes.
Cylinder cover is typically shorter than premium ranges; older units out of warranty are often better replaced than repaired.
Elements, thermostats and valves interchange with many Rheem-group models.
Most Vulcan tanks still in service in Hobart are well past their 8–12 year design life — many we attend are 15 years or older.
