Commercial Gas Water Heater Installation in Dover
Businesses in Dover often have high demands for hot water, requiring robust commercial-grade gas water heaters.

Atmospheric Vent Gas Water Heater Installation in Dover
Atmospheric vent water heaters rely on natural draft to move exhaust through a metal flue. They are common in older homes and are often the most affordable gas option. We inspect the existing vent for damage, proper slope and clearance. If the vent is undersized or corroded, we replace it. Proper draft is essential for safety.
Gas Tankless Water Heater Installation in Dover, NH
For endless hot water on demand, gas tankless water heaters are an appealing option for many homeowners. Installing these units requires dedicated venting and gas line sizing to handle the higher BTU input. FVR Plumbing provides expert tankless water heater installation, improving efficiency and ensuring your unit delivers hot water only when you need it. A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment. We use your local water quality to recommend appropriate pre-filtration.

Standard atmospheric vent gas water heaters typically cost less to install than power vent or tankless units. Venting changes, gas line upgrades and code corrections can add cost. We provide a written quote that includes the unit, labor, permits and haul-away. We also compare operating costs between gas and electric models. That helps you choose the best long-term value.
