What is a Tank Water Heater?

Storage tank water heaters generally have a capacity of 30 to 60 gallons. The capacity you want depends on your household size and how much hot water you require. Storage tank water heaters use natural gas, electricity, fuel oil, or propane to continuously heat water and keep a full tank ready at all times.

» How do Tank Water Heaters Work?

Traditional tank water heaters have been around since the early 20th century. The concept is simple: A reserve tank fills up with water and heats it. The heated water is distributed to your faucets until it’s empty. Once empty, the tank has to fill up with water and heat it again.

What is a Tankless Water Heater?

As their name implies, tankless, instantaneous, or on-demand water heaters don’t have a tank for storing water.

A tankless hot water system heats water only when you need it. So if you’re the only one taking a shower, you don’t need to heat water for five. The same applies to washing dishes, clothes, and whatever else you need hot water for. You might need a gallon, 30, or maybe 100; there is no limit to how much hot water a tankless system can produce. Sounds great, right? But there are also some drawbacks.

» How do Tankless Water Heaters Work?

Tankless water heaters don’t have a storage tank for hot water. Instead, they only heat water when you need it. This is how tankless water heaters produce hot water instantly:

When you open a hot water faucet in your home, cold water travels into the heater and runs through a burner or heat exchanger, where heating occurs. Once hot, it directly flows to the tap or shower you turned on. These heaters can heat up to five gallons of water in a minute.

What are the Differences Between a Tank Water Heater vs. Tankless Water Heater?

There are several ways in which these heaters differ that we can look into below, based on which you can then make a choice.

» Costs

Tank water heaters are generally more affordable than tankless water heaters in terms of purchase and installation costs.

Beyond the initial purchase and installation costs, tankless water heaters tend to be more cost-effective long term because they use less power than tank heaters to heat water.

» Energy Efficiency

Tankless water heaters are more energy-efficient in comparison to tank water heaters. They achieve this efficiency because they only heat water on demand instead of maintaining a constant supply and storage of hot water.

» Installation

When it comes to installation costs, installing a point-of-use tankless water heater will cost the least, followed by storage tank water heaters, then whole-house tankless heaters.

Some homeowners can DIY install traditional tank water heaters to save on water heater installation costs. However, it’s best to leave tankless water heater installation to a professional, as they are more complex.

» Size

Since traditional water heaters come with a storage tank, you need to account for that when setting aside some space for installation. On the other hand, tankless water heaters don’t have a tank, which is perfect if you don’t have plenty of room in your house.

» Performance

Tank water heaters hold a certain amount of hot water in their tank. If you choose the right size for your storage tank water heater, your home should not run out of hot water. On the other hand, since tankless water heaters heat water instantly, they might struggle to keep up with demand if two or more taps require hot water simultaneously. Thus, if your household demands a greater demand for hot water, you might need to install more than one tankless heater or install point-of-use models.

» Maintenance and Durability

Traditional tank water heaters have a lifespan of approximately 10-15 years, whereas tankless systems can last for over 25 years. Also, tanked water heaters require frequent maintenance to prevent rusting and other tank failures that cause leakages and damage your house.
