Tankless vs. Conventional Water Heaters

Hot water is an expected modern convenience. However, hot water can be provided to your home in two distinct ways. One involves a conventional water heater. The other is to invest in a newer, tankless model. Selecting the right option for your house is an important decision.

Conventional Water Heaters

Conventional water heaters use a large tank to hold a reservoir of water. The tank maintains a consistent temperature. These units are larger, typically spanning 5 feet by 2 feet and usually store 50 gallons of water. Because of the storage capacity, these appliances are better at providing consistently hot water. Tank water heaters are cheaper upfront but have higher monthly operating costs because they’re always working to keep warm water on standby.

Tankless Water Heaters

Tankless water heaters do not use a reservoir of water. Instead, water is heated on demand when it passes through a small heating unit before it reaches the showerhead or faucet.

This makes tankless units more energy-efficient and reduce energy costs. These units cost more to purchase and install, but the initial cost may be worth it in the long run. Tankless water heaters can be up to 34 percent more efficient.

Making the Choice For Your Home

There are many factors to consider when picking your water heater. This can include the following.

  • Water demand

  • Size of unit

  • Cost of energy bills

Ultimately, the decision comes down to the needs and preferences of each homeowner. It is important to understand the facts to make a choice that provides hot water to your home for years to come.
