Hard Water Protection for Tankless Units in Post Falls
Hard water can cause scale buildup in tankless heat exchangers and heating elements. Scale reduces efficiency and can trigger error codes. Private wells serve a large share of rural homes, and iron, sediment, and nitrate levels make regular well water testing a good habit. 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.

With proper installation and regular maintenance, an electric tankless water heater can last 20 years or more, which is much longer than the 10 to 15 year lifespan of a traditional tank unit. Their modular design also means components can often be replaced, extending their service life further.
Private wells serve a large share of rural homes, and iron, sediment, and nitrate levels make regular well water testing a good habit.

Regular flushing and descaling, often recommended once a year, are key maintenance steps to keep your unit running optimally.
Point-of-use installs often take a few hours. Whole-home installs can take a day, especially if new circuits are required.
HNV Plumbing installs a variety of reputable electric tankless water heater brands, including Rheem, Ecosmart, Stiebel Eltron, Bosch and Noritz. We can help you choose the best brand and model that fits your budget and hot water demands, providing a quality and efficient solution for your home.
Whole-home units can require 100 amps or more, so many homes need a panel review. We assess your panel and coordinate upgrades if needed.
Installing an electric tankless water heater is a demanding job involving high-voltage electricity and plumbing, making it unsuitable for DIY. Incorrect installation can lead to electrical hazards, water damage and voided warranties. It's always best to hire a licensed and experienced plumber like HNV Plumbing for safe and proper installation.
Most standard electric tankless water heater installations take between 4 and 8 hours. However, if significant electrical panel upgrades or extensive plumbing modifications are required, the process could extend to a full day. We always aim for efficiency without sacrificing quality.
