Condensing Tankless Replacement in Loveland
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through inexpensive PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Higher elevations lower the boiling point of water, which affects water heater settings and pressure relief performance in mountain homes. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth the price.

Recirculation Tankless Upgrades in Loveland, 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 popular in long single-story ranch homes.
Tank to Tankless Conversions in Loveland, CO
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.

Scale builds inside tankless heat exchangers over time, so a correctly sized replacement with flush valves protects homes in Loveland, CO from early failures.
