Recovery time is the number nobody thinks about until the tank runs cold mid-shower with guests in the house. It varies enormously by system type, so here is the honest comparison.
Recovery time by system type
| System type | Full reheat from cold | Practical meaning |
|---|---|---|
| Gas storage | Roughly 60 to 90 minutes | Fast recovery; short wait after heavy use |
| Electric storage, continuous tariff | Roughly 2 to 4 hours | Moderate wait, depends on element and tank size |
| Electric storage, off-peak tariff | Reheats overnight only | Run the tank dry at 6pm and it stays cold until the off-peak window |
| Heat pump | Roughly 3 to 5 hours | Efficient but unhurried; sizing matters |
| Gas continuous flow | Instant, no recovery | Never runs out; limited by flow rate, not volume |
Why does my electric hot water take so long?
Usually it does not take long, it takes until the tariff allows. A large share of Gold Coast electric tanks sit on economy tariffs that only energise the element during off-peak windows, typically overnight. That arrangement keeps running costs down, but it means a tank emptied by evening showers will not begin reheating until the window opens, no matter how long you wait. If your household regularly runs out in the evening, the options are a bigger tank, a tariff change, or a system type with faster recovery, and the right answer depends on your usage pattern. What it almost never is: a fault. We would rather tell you that on this page than charge a callout to read your meter board.
Which system should I choose if recovery time matters?
If your household hits hot water hard in bursts, big families, back-to-back showers, guests, then gas storage or gas continuous flow suits you best, and continuous flow removes the concept of running out entirely as long as the unit is sized to your flow demand. Heat pumps at $2,500 to $4,500 after rebates are the efficiency pick and pair beautifully with rooftop solar, but their leisurely recovery means sizing the tank correctly is critical, which is exactly what we assess at quote time. Published installed pricing: electric storage $1,300 to $2,400, gas storage $1,800 to $3,200, gas continuous flow $1,900 to $3,500.
How long after installation until I have hot water?
For a like-for-like swap done in a day, expect hot water the same evening: the tank fills, the system fires, and recovery runs as per the table above. Gas systems installed in the afternoon are usually showering the household by dinner. Off-peak electric installs are the one caveat, since the first full heat may wait for the tariff window, and we will tell you honestly if that is your situation so nobody is surprised at 8pm.
