Recirculation Tankless Upgrades in Longmont, CO
If you are tired of running the tap waiting for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.
Exterior Mount Tankless Units in Longmont, CO
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. Before leaving a home for a winter trip, keep the heat at a safe setting and consider shutting off the main water supply. 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 simplest swap when the gas line is already sized correctly.
