Converting from a storage tank to a tankless water heater is a popular Brentwood upgrade, but it's a real project, not a like-for-like swap. Tankless units fire hard and fast, so they often need a larger gas line (¾" minimum), new venting, and sometimes electrical and relocation work. We assess what your conversion requires up front, give you a clear quote, and do it properly so you get the endless hot water and efficiency tankless promises — without performance problems down the line.
The assessment is what separates a conversion that performs from one that disappoints. We check whether your existing gas line can feed the new unit, plan the venting route, and confirm any electrical needs before quoting — so there are no surprises mid-job. Because Brentwood's hard water scales tankless heat exchangers, we also fit isolation valves so future [descaling](/services/tankless-water-heater-descaling-maintenance) is quick. The result is the endless hot water and 20-year lifespan you're converting for, installed to code and built to last.
