Recirculation Systems for Tankless Heaters in Lexington
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, cutting wait time and water waste. Some units have built-in pumps with smart scheduling.

Commercial Tankless Water Heater Services in Lexington, KY
Businesses in Lexington benefit from the continuous hot water supply and compact design of commercial tankless water heaters. From restaurants to hair salons, we install heavy-duty systems designed to meet high-demand commercial needs. BFK Plumbing understands the requirements for commercial installations, including larger capacity units and commercial plumbing codes, so your business never runs out of hot water.
Tank to Tankless Conversions in Lexington
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 usually 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 dispose of your old tank and patch the old flue penetration.

Electric Tankless Water Heater Installation in Lexington, KY
Electric tankless water heaters are an excellent option for homes in Lexington where natural gas is not available or preferred. These units are often smaller, simpler to vent and can be installed closer to the point of use. BFK Plumbing provides professional electrical sizing to make sure your home's panel can safely support a new electric tankless unit, offering consistent hot water without the need for a gas line.
