Hard Water Protection for Tankless Units in Green Bay
Hard water can cause scale buildup in tankless heat exchangers and heating elements. Scale reduces efficiency and can trigger error codes.

We recommend a water softener or scale inhibitor to protect your unit, and we install service valves for periodic descaling. Regular maintenance helps extend the life of your tankless heater.

This setup is particularly efficient for reducing water waste and energy consumption in targeted areas.

HKV Plumbing also provides a labor warranty on our installation services. We will discuss specific warranty details for your chosen unit during your consultation.
With proper installation and regular maintenance, an electric tankless water heater can last 20 years or more, which is significantly longer than the 10 to 15 year lifespan of a traditional tank unit.

Sizing an electric tankless water heater correctly is essential and depends on factors like the number of hot water fixtures in your home, your incoming groundwater temperature and your peak hot water demand.
