Most standard hot water tanks take 30 to 60 minutes to fully reheat after being drained.
Here’s what affects that timing:
Tank size (40 vs 50 gallon)
Gas vs electric
Age of the unit
Sediment buildup
Incoming water temperature (hello, Alberta winters 👋)
If it’s taking longer than an hour to reheat, that’s often a sign something isn’t working properly. If you’re trying to decide on whether you need maintenance, repairs, or a whole new tank, reach out to our friendly customer care team! They can send one of our Technical Home Advisors out to help you make the best decision for your home.
