Tankless Water Heater Installation vs. Traditional Storage Tanks

A tankless water heater, also known as a demand-type water heater, heats water on demand. In other words, it heats water directly as it flows through the system. Unlike a traditional storage water heater, it lacks a storage tank, meaning it does not store or continuously reheat water. This is essentially how a tankless water heater saves energy.

A traditional storage water heater stores water in a large tank and constantly reheats stored water. One of the pros of a storage unit is the lower upfront cost. It is cheaper to buy and much quicker to swap out when it fails. The upfront cost of a tankless water heater often ranges from $1,500 to $4,500, while a storage unit typically costs between $800 and $2,000.

A storage tank water heater is recommended for those with a lower upfront budget, but remember it comes with standby energy loss and higher energy bills. In addition, it has a lower lifespan as compared to a tankless water heater. It’s a good idea to consult with a licensed plumber when you need help with choosing a water heater.

Energy Efficiency

As we’ve already highlighted, one of the biggest reasons homeowners consider tankless water heater installation is energy savings. Traditional tanks continuously heat stored water, even when no one is using it. This standby heat loss can increase energy consumption over time.

Tankless systems turn on only when hot water is needed, heating water on demand. For households looking to lower heating bills, this can be an appealing advantage. A tankless water heater installation can cut down your heating bills by 24% to 34%.

The amount of savings varies depending on household size, water usage habits, and the type of unit installed. If your heating bills are spiraling and you’re looking for upgrades that can lower utility bills, consider a tankless water heater installation.

Installation Costs

Traditional storage tank water heaters cost less to purchase and install. In many cases, replacing an existing tank with a similar model is relatively straightforward. A qualified plumber with years of experience in the industry can get the job done the same day.

Tankless water heater installation involves a higher upfront investment. Depending on the home's plumbing, gas supply, or electrical system, modifications may be necessary to support the new equipment.

While the initial cost of tankless water heater installation is higher, some homeowners view the long-term energy savings and extended lifespan as worthwhile benefits.

Lifespan and Maintenance

Storage tank water heaters last between 8 and 12 years, while many tankless systems can last 20 years or more with proper maintenance.

Both types require periodic maintenance, but tankless units often benefit from regular descaling to prevent mineral buildup that can affect performance. A storage tank water heater should be drained and flushed at least once annually to prevent sediment buildup at the bottom of the tank. It is also advisable to seek help from a local plumbing service when you notice signs of malfunctioning.
