Tankless Water Heaters

Tankless Water Heaters in Albuquerque

Tankless water heaters — also called on-demand water heaters — have become one of the most popular upgrades for Albuquerque homeowners. Instead of storing and constantly heating a large tank of water, a tankless unit heats water instantly as it flows through the system. The result is endless hot water, lower energy bills, and a unit that takes up a fraction of the space.

MGP Mechanical has been installing and servicing tankless water heaters throughout Central New Mexico for years. We'll help you determine if tankless is the right choice for your home and handle the entire installation professionally. Not sure whether to go tankless? Read our comparison of converting to a tankless water heater and our breakdown of the advantages of tankless water heaters.

Why Homeowners Are Switching

The biggest advantage of tankless is efficiency. A traditional tank water heater keeps 40 to 50 gallons of water hot around the clock, even when nobody's using it. That constant reheating accounts for a significant portion of your gas bill. A tankless unit only fires when you turn on a hot water tap, which can reduce water heating costs by 25 to 35 percent. Learn more about the technology in our guide on how tankless water heaters work.

Other benefits include a longer lifespan (typically 20 years versus 10 to 12 for tank models), a compact wall-mounted design that frees up floor space, and of course the luxury of never running out of hot water mid-shower.

Equipment We Install

We install Navien tankless water heaters — the industry leader in condensing tankless technology. Navien units achieve up to 0.96 UEF efficiency with 15-year heat exchanger warranties. Browse our Navien lineup to compare the NPE-A2 (with built-in recirculation) and NPE-S2 models.

Sizing and Installation

Proper sizing is critical with tankless water heaters. The unit needs to be matched to your household's peak hot water demand — how many fixtures you might run simultaneously. A unit that's too small won't keep up during high-demand times. We assess your home's hot water usage patterns and recommend the right size to ensure consistent performance.

Tankless installation is more involved than a simple tank swap. It typically requires upgrading the gas line for the higher BTU input, adjusting the venting, and sometimes upgrading the electrical connection. Our licensed technicians handle all of this, including permits and inspection.

Maintenance and Hard Water

Albuquerque's hard water is particularly tough on tankless water heaters. Mineral scale can build up inside the heat exchanger, reducing efficiency and eventually causing damage. We recommend annual descaling — a process where we flush the unit with a vinegar solution to dissolve mineral buildup. For long-term protection, pairing your tankless unit with a Navien WEC water treatment system or Navien PeakFlo scale prevention can significantly extend the life of your investment.
