The recovery time of a water heater, which is how long it takes for water to heat up after it has been exhausted from electric water heaters, is something we get a lot of questions about.
We have demonstrated 3 of the most common wattage types of water heater, and included heating recovery times for capacities from 5L up to 120L for each. The temperature rise used in our table is 50°C, for example from 10°C to 60°C.
