Like-for-Like Tankless Swaps in Thornton
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the quickest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or stuck. Most like-for-like swaps are finished in four to six hours.
Recirculation Tankless Upgrades in Thornton, 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 in check while saving thousands of gallons of wasted water a year. This upgrade is popular in long single-story ranch homes.

That includes any needed gas and water line adjustments and venting changes to meet current codes.
Emergency Tankless Replacement in Thornton, CO
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can usually get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak on arrival. Call (720) 727-9398 any time your tankless quits.

Tankless vs. Tank Water Heater Conversion in Thornton, CO
Considering converting from a traditional tank water heater to a tankless system in your Thornton, CO home? This is a common and beneficial upgrade, but it requires specialized expertise. We handle the entire conversion, which can involve rerouting gas lines, upgrading electrical service, modifying water lines and installing new venting. Our team makes for a smooth transition, so you can enjoy the long-term benefits of a modern, efficient tankless system.
Condensing Tankless Replacement in Thornton
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. Dry air, intense sun, and big daily temperature swings put steady stress on pipes, fittings, and outdoor plumbing in Colorado. 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.

Rinnai is a leading brand in the tankless water heater market, known for its quality and innovation.
