Atmospheric Vent Tank Upgrades in Somerville, MA
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. A loose or undersized vent can spill exhaust into the garage or closet. We replace damaged vent sections and draft hoods as needed. Then we test draft with the burner running before we leave.

Thermal Expansion Tank Installation in Somerville
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can stress your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a properly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.
Standard Vent Gas Water Heater Replacement in Somerville
Many homes in Somerville use standard atmospheric vent gas water heaters. When these units reach the end of their lifespan, typically 10 to 12 years, we provide expert replacement. Our service includes safely disconnecting the old unit, installing a new, energy-efficient model, and connecting it properly to your existing natural gas line and flue venting system. We also check for adequate combustion air and perform a thorough leak test for safety and efficiency.

Gas to Gas Brand Matching in Somerville, MA
Bradford White, Rheem and A.O. Smith each offer tanks with different warranty lengths, anode materials and burner designs. We explain the differences in plain terms so you know what you are paying for. Some models offer self-cleaning dip tubes that help with sediment in hard water.

Bradford White Gas Water Heater Installation in Somerville
BWM Plumbing is a trusted installer of Bradford White gas water heaters in Somerville. Known for their durability and American-made quality, Bradford White units are a popular choice for many Massachusetts homeowners. We confirm proper sizing and installation according to manufacturer specifications, extending the lifespan and efficiency of your new unit. Our technicians are familiar with their venting and gas connection requirements.

Power Vent Water Heater Replacement in Somerville
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.

Frequently Asked Questions About Gas Water Heater Replacement in Somerville
A standard 40 or 50 gallon gas water heater replacement usually runs $1,800 to $3,200 installed, including haul-away and basic code upgrades. Larger 75 gallon or power vent units usually cost $3,000 to $4,800. We give a firm price before starting.
Atmospheric vent water heaters use natural convection to vent combustion gases up a chimney or flue. Power vent models use an electric fan to force gases out, allowing for more flexible venting options and often higher efficiency due to cleaner combustion.
We install all major reputable brands of gas water heaters, including Rheem, A.O. Smith, Bradford White and Noritz. We can help you choose the best brand and model to suit your budget and hot water demands.
Tankless can make sense if you want endless hot water and plan to stay long term, but upfront costs are higher. We can price both options so you can weigh them side by side.
If your home has a pressure regulator or backflow device, heated water has nowhere to expand. An expansion tank absorbs that pressure and protects the heater and fixtures.
Common signs include a lack of hot water, rust-colored water, banging or rumbling noises from the tank, leaks around the base or repeated pilot light outages. An aging unit, usually over 10 to 12 years old, is also a strong sign.
Water pooling at the base, rusty hot water, rumbling or popping sounds and a tank over 10 years old are typical signs. A leak from the tank itself cannot be repaired.
Yes, in most areas of Somerville, MA, a permit is required for gas water heater replacement to confirm the installation meets local safety and plumbing codes. BWM Plumbing handles all necessary permitting for your convenience.
