Hard Water Protection for Tankless Units in New Haven
Hard water can cause scale buildup in tankless heat exchangers and heating elements. Scale reduces efficiency and can trigger error codes. Public water in most of Connecticut runs soft to moderately hard, and soft water can be slightly corrosive to older copper plumbing. 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.

Electric Tankless Replacement and Upgrades in New Haven
Older electric tankless units may struggle to keep up or show frequent error codes. We replace aging units with newer, more efficient models. Upgrades may include higher kilowatt ratings or better flow control. We check wiring and plumbing connections during replacement. A new unit can restore reliable performance.
Electric Tankless Water Heater Sizing and Selection in New Haven
Choosing the right electric tankless water heater size is crucial for performance. In New Haven, factors like groundwater temperature and your household's simultaneous hot water usage determine the right GPM (gallons per minute) output required. GLV Plumbing provides expert consultation to help you select a unit that closely matches your demand, preventing cold showers and ensuring efficiency. We consider your home's plumbing layout and electrical panel capacity to recommend the best model.
Upgrading from Tank to Tankless Electric in New Haven
Many New Haven homeowners are making the switch from traditional tank-style water heaters to electric tankless models.

Our plumbers manage these complexities, ensuring a smooth transition and getting the most from the benefits of your new system.

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