Why Choose FVR Plumbing for Gas Water Heater Replacement in Dover, NH?
Water in much of New Hampshire is soft and often slightly acidic, which can slowly corrode copper pipe and cause pinhole leaks. Sediment that settles in the bottom of gas tanks overheats the steel and cuts tank life. We set up each new heater so sediment can be flushed and the anode rod can be checked.
- Safety First, Gas appliances require careful handling, and our technicians are rigorously trained in all safety protocols and code requirements for gas water heater installation.
- Code Upgrades, We bring straps, venting, drain pans and relief lines up to current code as part of the job.

Standard Gas Water Heater Replacement in Dover
Most homes in Dover use a conventional tank-style gas water heater. We expertly remove your old unit, inspect the existing gas and water lines, and install a new, energy-efficient model. Our service includes proper venting setup and confirming all connections are leak-free and secure. We work with various tank sizes to match your household's hot water demand, balancing efficiency and longevity in your local climate.
Power Vent Water Heater Replacement in Dover
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails again and again, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve difficult placement problems.

If you are looking to switch from a traditional tank to a tankless gas water heater, FVR Plumbing can handle the entire conversion in Dover.

Atmospheric Vent Tank Upgrades in Dover, NH
Most older homes have atmospheric vent water heaters that rely on natural draft up a metal flue. We inspect the flue pipe for rust, proper slope and correct connector size during replacement.
