Hard Water Protection for Tankless Units in Dublin, OH
Calcium scale is the leading cause of tankless heater failure. Much of Ohio has hard water, which leaves scale in water heaters, clogs aerators and cuts the life of appliances. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides added protection.

Frequently Asked Questions About Tankless Water Heater Installation in Dublin
Most gas tankless installations cost $3,000 to $6,500 including the unit, labor, venting and typical gas line upgrades. Electric units can be less, though panel upgrades can add $1,000 to $3,000.
Tankless units eliminate standby heat loss, which can reduce water heating energy use. Savings vary based on household size and usage habits.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that considerably.
We install leading tankless water heater brands known for their reliability and efficiency, including Rinnai, Navien, Noritz and Rheem. Our plumbers are trained and experienced with the specific requirements of each manufacturer to ensure strong performance.
Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also warranty our installation labor.
To maintain efficiency and extend the lifespan of your tankless unit, annual flushing to remove mineral buildup is recommended, especially in areas with hard water. Checking and cleaning the air filter (for gas models) and inspecting connections are also part of regular maintenance. HRL Plumbing offers complete maintenance services.
A standard tankless water heater installation, replacing an existing tank, usually takes 4 to 8 hours. If extensive plumbing or gas line changes are required, it may take a full day. Our team works efficiently to restore your hot water as quickly as possible.
No, we firmly advise against DIY tankless water heater installation. These systems involve complex connections for gas, water and electricity, along with specific venting requirements. Improper installation can lead to safety hazards, void warranties and costly repairs. Always use a licensed professional.
