To Flush, Or Not To Flush

Water heaters are one of the most crucial parts of a home’s plumbing system. From daily showers to laundry, dishes, and handwashing, your water heater works constantly behind the scenes. Because it’s such an essential (and expensive) appliance, choosing the right water heater for your home and family is an important decision.

One of the most common questions we get from homeowners is whether they should replace their traditional tank-style water heater with a tankless water heater. If you know it’s time to replace your water heater, or if you’re starting to notice signs of aging, we can help you evaluate your options and choose the best solution for your needs, your home, and your budget.

Traditional Tank-Style Water Heaters

Tank-style water heaters are the most common type of water heater found in homes. They store a set amount of hot water in a tank and keep it heated so it’s ready when you need it.

Choosing the Right Tank Size

Tank water heaters come in a variety of sizes, typically ranging from 30 to 80 gallons. Choosing the right size depends on:

  • The number of people in your household
  • How much hot water is used at one time
  • Appliances that rely on hot water (washing machines, dishwashers, etc.)

Larger families or homes with multiple bathrooms may require a larger tank to prevent running out of hot water during peak usage times.

Lifespan and Maintenance

A traditional tank-style water heater usually has a lifespan of 8–10 years. In older cities like Chicago, sediment buildup from aging pipes can shorten that lifespan if maintenance is neglected. Annual water heater maintenance helps:

  • Flush out sediment buildup
  • Improve efficiency
  • Reduce the risk of leaks or unexpected failure
  • Extend the life of the unit

Tank-style water heaters are generally more affordable upfront and are often easier to install, making them a popular and reliable choice for many homes.

Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, heat water only when it’s needed. Instead of storing hot water in a tank, they heat water as it flows through the unit.

Benefits of Tankless Water Heaters

Tankless water heaters have grown in popularity due to several advantages:

  • Space-saving design – compact and wall-mounted
  • Improved energy efficiency – no energy wasted keeping water hot in a tank
  • Longer lifespan – typically 12–15 years
  • Continuous hot water – no running out during long showers or back-to-back use

These features make tankless water heaters especially appealing for homeowners looking to improve efficiency or free up space.

Maintenance and Considerations

Like tank-style heaters, tankless water heaters should be serviced once a year to prevent scale buildup and ensure optimal performance. However, tankless systems are not a one-size-fits-all solution.

When converting from a tank-style water heater to a tankless system, there are important factors to consider:

  • Venting requirements are different and may require modifications
  • Gas line or electrical upgrades may be necessary
  • Building limitations: some homes or multi-unit buildings may not be able to accommodate a tankless conversion

This is why a professional evaluation is essential before making the switch.

Which Water Heater Is Best for Your Home?

Both tank-style and tankless water heaters have their advantages. The right choice depends on:

  • Your household’s hot water usage
  • Available space
  • Energy efficiency goals
  • Budget and long-term plans
  • Your home’s existing plumbing and venting setup
