Attic Water Heater Replacement in Dover
Older homes frequently show decades of patchwork plumbing, so repiping can make more sense than repairing one section at a time.

Frequently Asked Questions About Water Heater Replacement in Dover
The cost of water heater replacement in Dover, NH typically ranges from $1,200 to $3,500, depending on the type of unit (gas, electric, tankless or hybrid), its capacity and any needed plumbing modifications. Our team will provide a detailed, upfront quote after assessing your needs and existing setup.
Tank water heaters often last about 8 to 12 years, and hard water and sediment buildup can shorten that. Water in much of New Hampshire is soft and often slightly acidic, which can slowly corrode copper pipe and cause pinhole leaks. Annual flushing and anode rod checks can help lengthen that life.
We install Bradford White, Rheem and A.O. Smith water heaters. Each offers dependable performance and a range of warranties.
Many households of two to three people do well with a 40 gallon tank, while larger families often need 50 gallons or more. We size according to your bathroom count and usage.
Yes, in many areas of Dover and New Hampshire, a plumbing permit is required for water heater replacement to make sure the installation meets local safety and building codes. FVR Plumbing handles all necessary permitting on your behalf, so you do not have to worry about compliance.
Leaks at the base, rusty water, rumbling noises, inconsistent hot water and an age over 10 years are typical signs. A leaking tank should be replaced right away.
Tankless offers endless hot water and a longer lifespan but costs more upfront. We can compare both options around your household and budget.
Choosing the right size depends on the number of people in your household, their hot water usage habits and peak demand times. Our technicians will calculate the appropriate GPM (gallons per minute) for tankless or gallon capacity for tank models so you never run out of hot water, especially in multi-bathroom Dover homes.
