Hard Water Can Shorten the Life of Your Water Heater


Wisconsin is known for hard water, which can take a toll on your plumbing system and water heater over time. As minerals build up inside your tank or heat exchanger, your system has to work harder to produce hot water. The result can be reduced efficiency, higher utility bills, and a shorter lifespan for your equipment. Installing a water softener can help protect your investment and keep your water heater running efficiently for years to come.

How hard water affects your water heater:

Sediment and scale buildup inside the tank
Reduced heating efficiency and slower recovery time
Higher energy costs to compensate for scale buildup
More frequent flushes and repairs

If your unit is under 10 years old and has a single fixable issue like a bad element or a leaking valve, repair is usually the right call. If it is over 10-15 years old, has multiple problems, or the repair cost is more than half the replacement cost, we will typically recommend replacing it. We will give you an honest recommendation after diagnosing the issue.

The cost depends on the unit type, size, and fuel source. Tank water heaters typically run lower than tankless units. We provide upfront pricing before starting any work so there are no surprises. Call us at 608-416-5646 for a service estimate.
