Do you have an idea how long does a water heater take to heat up? If not, this guide is for you.
Hot showers offer us the most wonderful experience in our residences. However, our water heaters are not magic devices that can create an endless hot water supply.
They take time to turn the water hot. However, not all water heaters take the same amount of time to heat up, so it is necessary to consider how long a water heater takes to heat up.
Although they are available in various sizes, the 40-gallon capacity is the most common. The larger the water heater, the longer it takes to heat water.

Time Required to Heat Water with Different Types of Heaters
Water heaters are available in various sizes, kinds, and fuel or energy sources. These variables affect the time required for the water heater to warm up.
Gas Heaters for Water
Low electricity bills are one of the main advantages of gas water heaters. Instead of using battery-powered elements, they use gas burners at the bottom of the tank to warm. As a result, their heating rate is greatly reduced.
The average gas heater does not take much time to warm a full tank. A 40-gallon tank takes 30 to 40 minutes to warm, while an 80-gallon tank takes 60 to 70 minutes.
Electric Heaters for Water
Electrical water heaters are less efficient in general. Inside the tank, they use electric heat sources like those used in an oven or toaster. Their recovery period is longer than that of gas-powered units.
30-gallon and 20-gallon water heaters have small hot water tanks, and they are nearly impossible to supply your whole house. Hot water should be available in 70 – 90 minutes with a 50-gallon tank. A 70-gallon water heater takes two hours to warm water.
Only Housing and Urban Development (H.U.D)- approved 20-gallon electric water heater for mobile homes should be used because this US department has separated mobile home water heaters from regular heaters.
Solar Heaters for Water
Solar water heaters are converted into electrical energy by the sun. We cannot always depend on clear skies, so a regular electric water heater usually supplements them. This means they support roughly the same time as an electric component.
There are solar devices that run entirely on solar power. On dark days or wintertime, you may be without hot water.
Heat Pump Heaters for Water
Heat pump heating units are frequently referred to as hybrids or modified electronically controlled water heaters. Rather than producing direct heat, they spread heat using the input electricity and raising their performance.
Heat pump units are typically computerized, with many energy-saving setups. These are typically hybrid and high-demand modes. The unit consumes less energy in hybrid mode, but the heating rate increases.
The waiting time for hot water in hybrid mode can be roughly two hours, depending on the tank size. However, if you change to high-demand, the electric component of the device will activate, reducing the waiting time to 60 to 80 minutes.
Tankless Heaters for Water
A tankless model is ideal if you want a water heater with minimal or no waiting time. Tankless or on-demand heating systems are only activated when required.
They have a short-sized tank, so the water only comes in when needed and gets heated as it goes around.
Things That Affect How Fast a Water Heater Heats
The time required for a water heater to warm up depends on various variables. Understanding these factors can help explain why some heaters heat water more quickly than others.
Size of Water Heater
Size of Water HeaterThe capacity of all heaters is not similar. An average gas water heater holds about 40 – 50 gallons, and bigger tanks give you more hot water.
40-gallon water provides up to 2 showers in one hour, and a 20-gallon gas water heater provides a shower in one hour. They are best for small houses.
The capacity of the heating chamber affects the water heater’s first-hour rate and time to recover. The first-hour rate shows how many gallons of hot water the unit can deliver per hour when the tank is full.
The recovery period shows the system’s potential to deliver warm water after emptying its contents in an hour. Several factors influence recovery time, including the heater’s performance and tank size.
Type of Fuel
Type of FuelFire is a chemical reaction that shows how temperature, oxygen, and fuel work together. The resulting fire breaks molecular bonds and provides heat and thermal energy. So, gas is a better way to heat than electricity.
Some homes use the sun to power a solar heater as a backup supply. Even though using a solar heater to warm water is cheaper, you may have to wait longer than if you used gas heaters or electric components.
Problems with Maintenance
Problems with MaintenanceIf you don’t wash the heater’s storage tank often, debris will build up, and waxy buildup will form on the heating elements. Salt deposits and debris buildup can make the heating system less effective.
The problem is worse in homes with hard water because the water has more iron, nutrients, and other toxic substances, causing sediment buildup, damaging the pipes and heater, and making them less effective. Choose a water heater for hard water.
Diameter of Pipe
Diameter of PipeLarge-diameter water pipes are great because they carry more water to the washbasin, shower, and other places in the house. The flow rate of these pipelines is also greater, which means more warm water for everybody.
Water Appliances Distance
Water Appliances DistanceIf the water heater is 100 feet from the bathroom, the water temperature at the bathroom will be a little cooler than if it were five meters away. To get the most out of the hot water, installers of water heaters measure the distance between the unit and all appliances that use hot water.
Hot water doesn’t last long in the shower because of the long distance between the unit and the shower. When the pipelines are long, hot water takes too long to come to the shower.
Keep in Mind
If you are away from home for more than one day, turn off the main supply of water and water heater. Never forget turning on the water heater and turning water back on after vacation.
FAQs – Frequently Asked Questions
How Much Time is Required for a 50-Gallon Heater to Warm Up?
A fifty-gallon water heater takes forty to fifty minutes to warm up.
How Long Does it Take for Hot Water to Return?
It takes 30 to 40 minutes for a hot water tank to warm up. You’ll have to wait for a half-hour for the hot water to come back on.
How Long Will it Take for Water to Become Hot?
After switching on a water heater, it requires 30 to 40 minutes for the water to reach the desired temperature.
How Can I Get My Water Heater to Heat Up More Quickly?
Follow these steps to get the water warmer more quickly and make hot water last longer.
- Keep the pipes warm.
- Pump to Bring Hot Water Back Around.
- Pipes with a higher speed flow should be changed.
- Transform to a water heater without a tank.
- Regular maintenance for safety.
Is it Possible that You Will Run Out of Warm Water?
You may run out of hot water if you have a large family and everybody take a bath at the same time.
Why is it Taking More Time for Water to Heat Up?
How far the water heater is placed, the size of the pipelines, and the water flow rate are all factors that may increase the heating time. The longer the hot water has to travel to reach the shower faucet, the longer it will take to heat it.
Final Thoughts
Several things determine how long a water heater takes to heat your water. Gas-powered water heaters are much faster than electrically powered ones.
The recovery period often increases unexpectedly, which could indicate sediment buildup. Therefore, flush the tank in particular circumstances or seek professional assistance with a substitute.
We all like to use hot water as early as possible. So, by trying to maintain your water heater and, if necessary, upgrade it. So by trying to maintain your water heater and, if necessary, upgrade it.
