Hard Water Protection for Tankless Units in Castro Valley
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.
