Tank to Tankless Conversions in Topsham
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line often needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and haul away your old tank and patch the old flue penetration.
Recirculation Systems for Tankless Heaters in Topsham
Tankless heaters can take a few extra seconds to deliver hot water to distant fixtures. A recirculation pump or dedicated return line keeps hot water close to faucets, reducing wait time and water waste. Some units have built-in pumps with smart scheduling. We design the system to fit your plumbing layout and usage patterns.
Hard Water Protection for Tankless Units in Topsham, ME
Calcium scale is the leading cause of tankless heater failure. Many Maine homeowners on wells use water treatment such as neutralizers, filters, or softeners to protect their plumbing. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides extra protection.

Frequently Asked Questions About Tankless Water Heater Installation in Topsham
The cost for tankless water heater installation in Topsham can range from $3,000 to $6,000, based on the unit type (gas or electric), brand, capacity and complexity of the installation, such as gas line upgrades or new venting. This price typically includes the unit and professional labor. We provide a detailed, no-obligation estimate after an on-site assessment.
Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems specifically, frequent error codes or a significant drop in hot water flow could point to a need for service or replacement.
Size depends on how many fixtures run at once and your incoming water temperature. Many homes need a unit rated around 7 to 10 gallons per minute.
Tankless water heaters benefit from annual flushing to remove mineral buildup, especially in areas with hard water. This helps maintain efficiency and prolong the unit's lifespan. We offer maintenance services to keep your system running smoothly.
Tankless water heaters offer several key benefits: endless hot water on demand, real energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also reduce the risk of tank leaks and the water damage that comes with them.
To maintain efficiency and extend the lifespan of your tankless unit, annual flushing to remove mineral buildup is recommended, especially in areas with hard water. Checking and cleaning the air filter (for gas models) and inspecting connections are also part of regular maintenance. BKN Plumbing offers comprehensive maintenance services.
Yes, gas tankless water heaters require specific venting materials and configurations different from traditional tank heaters. Many modern units use PVC or polypropylene for venting, and proper slope and termination are critical for safe and efficient operation. Electric units do not require venting.
Most tankless water heaters come with a manufacturer's warranty of 10 to 15 years on the heat exchanger and 3 to 5 years on parts. BKN Plumbing also provides a warranty on our installation labor, which we will detail in your service agreement.
