Electric water heaters take twice as long as a gas heater to heat up. It takes approximately two hours to heat an 80-gallon water tank. The advantage is that it uses less energy, since the thermostat simply turns on the heating system when the water temperature drops. With a recovery efficiency of 75%, gas heaters produce 27.3 gallons per hour with a 30,000 BTU burner, compared to 3.1 gallons per hour for electric heaters with a 750 watt heating element.
There's not much that can ruin your day as quickly as an icy shower, and if you have the wrong hot water heater, this could become your new normal. Keep reading if you want to learn about standard payback time and things you can do in case your water heater doesn't fill up. If you have a smaller size tank or a higher BTU rating, the heating time of your hot water heating system will be much shorter. The lower heating element does most of the heating once cold water enters the tank, while the upper one serves mainly to maintain the temperature of the hot water.
They can layer and displace water, reducing the amount of water available to your home. If you want to run a lot of hot water at the same time, you'll need a more efficient system than if you just want a daily hot shower. This is why households with higher water demands generally decide to buy a whole-house gas tank water heater instead of an electric model. A tankless gas heater heats the water immediately, so it should only take a couple of seconds before the hot water reaches its component through the pipes.
From the moment new water comes in, an electric water heater would take about an hour to heat the 40-gallon tank explained above. The translation, the amount of water you're heating, plus the amount of heat you apply to it, determines how quickly you get hot water. So how long does it take for a hot water heater to reheat the water once it runs out? While there are many elements that can affect time, the following table shows how long it takes for each type of water heater to warm up normally. Draining a few buckets of water from the drain valve until there are no more visible particles usually solves the problem.
