You depend on the water heater in your Bloomington, IL, home to supply you with the right amount of hot water when you need it. When it’s time to replace your old water heater, you might consider a tankless water heating unit. Before you decide on which type to get, consider these pros and cons of tankless water heaters from our qualified service technicians.

Space Requirements

When space is at a premium in your home, a tankless water heater is a good choice. They don’t require the bulky storage tank of a traditional water heater. They can be installed in a laundry closet, bathroom or kitchen. On the other hand, they do require connections to a gas supply line, water line, and electricity. They also need a flue for releasing the combustion gases.

Operating and Installation Costs

Tankless water heaters are more energy-efficient. According to the Department of Energy, tankless water heaters use 24 to 34 percent less energy than a traditional water heater. This means lower utility bills, especially if your household uses a lot of hot water. Keep in mind that tankless water heaters cost more to purchase and install. For most homeowners, the higher initial investment leads to overall savings. This is because a typical tankless water heater has a 20-year lifespan compared to 10 years for a standard water heater.


Tankless water heaters don’t actually supply an unlimited amount of hot water. If you’re washing dishes or laundry while someone else showers, the supply could be interrupted. This won’t usually happen with an 80-gallon hot water tank. However, an 80-gallon water tank takes a long time to refill and attain the temperature set on its thermostat. No matter which type you choose, both have limits on their capacity.
