We design the system to suit your plumbing layout and usage patterns.

Rinnai Tankless Water Heater Installation in Nashua, NH
Rinnai tankless water heaters are a popular choice for their reliability and long lifespan, making them a smart investment for homeowners across Nashua, NH. Our plumbers are factory-trained on Rinnai systems, ensuring a clean installation that follows all manufacturer specifications. We make sure gas line sizing, venting and water connections are correct so your Rinnai unit provides endless hot water efficiently for years.
Hard Water Protection for Tankless Units in Nashua, NH
Calcium scale is the most common cause of tankless heater failure. Water in much of New Hampshire is soft and often slightly acidic, which can slowly corrode copper pipe and cause pinhole leaks. 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 Nashua
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.
Residential Tankless Water Heater Installation in Nashua
FVR Plumbing specializes in installing tankless water heaters for residential properties. We assess your home's hot water demands, family size and existing utility connections to recommend the most suitable unit, so you get the right capacity for your needs. Our installations are designed to be energy efficient, providing endless hot water while often lowering your monthly utility bills in Nashua.
Tankless vs Tank Cost Comparison in Nashua, NH
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 offset 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 suits your budget.

Frequently Asked Questions About Tankless Water Heater Installation in Nashua
Most gas tankless installations cost $3,000 to $6,500 including the unit, labor, venting and common gas line upgrades. Electric units can be less, though panel upgrades can add $1,000 to $3,000.
Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems specifically, frequent error codes or a significant drop in hot water flow could point to a need for service or replacement.
No, we strongly 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 hire a licensed professional.
In New Hampshire, plumbing and often gas or electrical permits are usually required for tankless water heater installation. FVR Plumbing handles all required permit applications and makes sure your installation passes all required inspections by local authorities.
Yes, tankless water heaters are very energy efficient in almost any climate. Humid summers bring condensation on cold water lines and damp basements that can hide slow leaks. Since they only heat water on demand, they avoid the standby heat loss common with traditional tanks, which can be substantial even in milder seasons.
Tankless water heaters offer several key benefits: endless hot water on demand, significant energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also reduce the risk of tank leaks and the water damage that comes with them.
Yes, a permit is typically required because the job involves gas, venting and water connections. We pull the permit and schedule the inspection.
Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also warranty our installation labor.
