Upgrading from Tank to Tankless in Greenville, NC
Making the switch from a traditional tank water heater to a tankless system involves more than simply swapping units. It often requires changes to gas lines, electrical wiring and venting. HFN Plumbing manages all aspects of this conversion, making sure all upgrades meet current codes and your new tankless unit performs optimally, giving you a modern hot water solution in Greenville, NC.
Hard Water Protection for Tankless Units in Greenville, NC
Calcium scale is the most common cause of tankless heater failure. A large share of homes across the state rely on private wells, and iron and manganese often leave rusty or dark stains on fixtures. 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.

Tank to Tankless Conversions in Greenville
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line usually needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and dispose of your old tank and patch the old flue penetration.
