Tank to Tankless Conversions in Exeter
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 haul away your old tank and patch the old flue penetration.

Businesses often have higher and more consistent hot water demands than homes.

Upgrading from Tank to Tankless in Exeter, NH
Making the switch from a traditional tank water heater to a tankless system involves more than just swapping units. It often requires changes to gas lines, electrical wiring and venting. FVR 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 Exeter, NH.
Hard Water Protection for Tankless Units in Exeter, NH
Calcium scale is the most common cause of tankless heater failure. Testing well water around Exeter is the right first step before choosing a treatment system or filter. 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 extra protection.
