Exterior Mount Tankless Units in Kirkland, WA
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 wear out plastic covers and wiring over time. Eastern and mountain areas of Washington freeze regularly and deeply, so insulated pipes and winterized irrigation systems are standard. 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 shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Commercial Tankless Replacement in Kirkland
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they split the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is flexible, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.
Tank to Tankless Conversions in Kirkland, WA
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.
