Tankless vs. Tank Water Heater Conversion in Everett, MA
Thinking about converting from a traditional tank water heater to a tankless system in your Everett, MA home? This is a common and worthwhile upgrade, but it requires specialized expertise. We handle the entire conversion, which can involve rerouting gas lines, upgrading electrical service, modifying water lines and installing new venting. Our team makes for a smooth transition, so you can enjoy the long-term benefits of a modern, efficient tankless system.

Exterior Mount Tankless Units in Everett, MA
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. Frozen pipes are a real winter risk across Massachusetts, especially during stretches of single-digit nights and strong wind. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to guard the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.

We also replace the old service valves if they are corroded or seized. Most like-for-like swaps are done in four to six hours.

Frequently Asked Questions About Tankless Water Heater Replacement in Everett
A like-for-like gas tankless replacement usually runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before any work starts.
Yes, tankless water heaters are usually more energy-efficient than traditional tank models. They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to significant savings on your utility bills over time, especially in homes with varying hot water usage.
DIY tankless water heater replacement is usually not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to dangerous gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like BWM Plumbing.
To extend the life and efficiency of your new tankless water heater, regular maintenance is key, especially in areas with hard water. This typically involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. BWM Plumbing offers maintenance plans to help keep your unit in top condition.
A direct swap usually takes four to six hours. A tank to tankless conversion with new gas and venting typically takes a full day.
New tankless water heaters usually come with a manufacturer's warranty, which usually covers the heat exchanger for 10 to 15 years and parts for 3 to 5 years. BWM Plumbing also provides a labor warranty on our installation work for your peace of mind. We will go over warranty details for your chosen unit during your consultation.
A standard tankless water heater replacement usually takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion can call for more extensive changes to gas lines, electrical or venting.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail far sooner. Annual flushing makes the largest difference.
