Upgrading from Tank to Tankless in Sammamish, WA
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. FHN Plumbing manages all aspects of this conversion, making sure all upgrades meet current codes and your new tankless unit performs at its best, giving you a modern hot water solution in Sammamish, WA.
Hard Water Protection for Tankless Units in Sammamish, WA
Calcium scale is the most common cause of tankless heater failure. Soft water can be slightly corrosive to copper over time, which sometimes shows up as pinhole leaks in older supply lines. 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.
Propane Tankless Water Heater Installation in Sammamish
Many homes outside natural gas service areas rely on propane. FHN Plumbing is experienced in installing propane tankless water heaters, which require specific gas line sizing, regulator adjustments and venting. We make sure your propane system is installed correctly for maximum efficiency and safety, providing reliable hot water for your Sammamish residence.

If your old tankless unit is failing or you are upgrading from a traditional tank, FHN Plumbing offers seamless tankless water heater replacement.

Our goal is to make the transition as smooth as possible, keeping continuous hot water in your Sammamish, WA home.
Tankless vs Tank Cost Comparison in Sammamish, WA
Tankless installation costs more upfront than a standard tank because of the unit price, gas line upgrades and venting changes. Over time, lower standby energy losses and a longer expected lifespan make up for part of that cost. Tankless units often last 15 to 20 years with proper descaling, compared with about 8 to 12 years for many tanks in hard water areas. We give you a side-by-side quote so you can decide what fits your budget.
Tank to Tankless Conversions in Sammamish
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 often 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.
