Tankless Water Heaters

Santa Fe Tankless Water Heater Services

Serving Rio Arriba, Los Alamos & San Miguel Counties

Tankless water heaters provide hot water on demand without storing a heated supply in a tank. Homeowners in Santa Fe may choose them for a smaller equipment footprint, a continuous supply of hot water within the unit’s capacity, or an alternative to a storage-tank water heater.

At Capitol Contractors, we provide tankless water heater installation, repair, and maintenance in Santa Fe, Rio Arriba County, Los Alamos County, and San Miguel County. Our services include installing a new system and repairing or maintaining an existing unit.

Our evaluation can determine whether your current unit needs repair or maintenance, whether replacement is appropriate, and whether a new system fits your household’s hot-water demand. We have been serving our community since 1968.

Call (505) 989-7916 or reach out online to schedule tankless water heater service.

How Do Tankless Water Heaters Work?

Instead of heating and storing water, tankless water heaters produce hot water on demand. When a homeowner turns on their shower, faucet, or any other fixture, cold water flows into the tankless unit. The water passes through a heating element that warms it to the desired temperature. Then, the unit directs the water to the fixture for use.

Most tankless water heaters have flow rates between two and five gallons per minute (GPM).

Actual performance depends on the incoming-water temperature, fixture flow, and simultaneous hot-water demand. A unit’s rated flow should be compared with how many showers, faucets, or appliances may need hot water at the same time.

Why Install a Tankless Water Heater?

The benefits of tankless water heaters include:

  • Energy Efficiency: According to the U.S. Department of Energy, tankless units can be 24% to 34% more efficient than a standard water heater for homes that use 41 gallons or less of hot water daily.
  • Potential Operating Savings: By heating water on demand, tankless units may lower operating costs, though energy use varies based on the equipment, fuel source, household demand, incoming-water temperature, and maintenance condition.
  • Longer Lifespan: While storage tank water heaters typically last around eight to twelve years, tankless units can last 20 years or more.
  • On-Demand Hot Water: Tankless units produce hot water as needed without storing heated water in a tank.

While tankless water heaters are more expensive upfront than storage units, the comparison should account for equipment, installation requirements, maintenance, and expected household use. Consult with our team at Capitol Contractors about installing a tankless water heater at your home in Santa Fe. We can compare system requirements with your needs and budget.

Tankless Water Heater Installation Considerations

A new tankless water heater installation starts with the home’s expected hot-water use. We work with systems from major name brands and can evaluate simultaneous demand, available gas supply or electrical capacity, venting requirements for gas-fired equipment, and an appropriate installation location.

Mineral scale can reduce tankless equipment performance over time, making periodic flushing or descaling an important part of hot-water maintenance. Water heater permits may also be required depending on the property and scope of work. Within the City of Santa Fe, plumbing and gas work is handled through the city’s secondary permit process, and the city has adopted the 2021 New Mexico Plumbing Code with City of Santa Fe UPC amendments. Project-specific requirements should be confirmed with the city’s Building Division.

Tankless Water Heater Repair

If your tankless water heating system isn’t working properly, we can diagnose whether it needs repair or maintenance.

Warning signs may include:

  • No hot water
  • Fluctuating temperatures
  • Unusual noises
  • Reduced hot-water flow
  • Leaks
  • Displayed error codes

Mineral buildup, ignition or gas-supply concerns, venting issues, sensor faults, electrical problems, and demand beyond the unit’s capacity can all require professional attention.

Gas, electrical, venting, and combustion-related concerns should be professionally diagnosed rather than handled through homeowner troubleshooting. In a plumbing emergency, call (505) 989-7916. In all other situations, schedule a convenient repair appointment.

We also offer service in Spanish. For urgent plumbing concerns, our team is available 24/7 to take your call.

    "Excellent work"
    Our heat went out late Saturday night - We called Capitol Plumbing and the crew, two men, Xavier and Alex, were here early Sunday morning. The furnace was removed and by 6:00 pm the new furnace was up and working - The heat was on and the house warmed up quite fast. Xavier and Alex were friendly and worked very efficiently replacing the old furnace. They were very helpful and informative and explained everything about the new furnace and answered all our questions. When crew had completed the job, they waited until the temperature was up to the degrees necessary for furnace to work. Thank you for a job well-done and I would recommend Capitol Plumbing and Heating in Santa Fe to anyone who needs plumbing work done. Thank you, we are once again warm and cozy.

    "Emergency service was also quick and efficient and very Professional."
    Xavior, arrived at a much needed time to fix our leak. He was fast to detect the leak and addressed the situation in a professional manner. It was late and after hours but he was not hurried and explained what happened, what he did and what has yet to be done. If you are not using them or need good service we recommend them, they responded among the many we tried to reach, so they will have our business for some time to come. Thank you for relieving our problem and minds.

    "Service with humor!"
    After being stood up by another plumber we called Paul's Plumbing & Heating, Inc. They contacted Xavier and Beto from Capitol Plumbing and Heating who fixed our outdoor faucet, which would not turn off. Xavier explained everything and showed us the process. He was professional, witty, and patient with my questions. I highly recommend them and am also impressed Paul's Plumbing contacted them since they didn't have any available crews. Both companies have customers' best interests in mind.

    "Very happy with Xavior and Capitol"
    My kitchen sink x2 was hopelessly plugged up. Filthy water that had backed up was just sitting there. That is so unhealthy. I called Capitol this morning and they said they'd send out a serviceman in a couple of hours, which they did. Xavior came by and did a great job. He was polite, knowledgeable, smart and neat....no mess left behind for me! And best of all, the drains are running perfectly! Capitol has also installed my furnace and water tank, all within the last year or so (3/2021). And I am VERY pleased with that result as well....thanks to Adrian for that....great job.

    "$1200.00"
    Both Tomas and Xavier Martinez were prompt and courteous. They went beyond what was a leaking hot water valve. After replacing the valve and water line hose, they checked the boiler system and found it was not properly operating and took care of it for us. We were thankful for their thoroughness and quick service.

    "Excellent friendly knowledgeable service."
    Had them install a complete new system for heating water and and radiant heat system. Went to a tankless hot water system. They worked very efficiently and wasted no time installing the system. Workers were friendly and explained everything about the equipment and answered my questions since I was not familiar with the tankless hot water system and the radiant heat used in homes. They hauled away the old tank and boiler and a soft water system that was out dated. It took about two days but the water was only off for part of the first day and we had hot water that night for showering. Over all a very positive experience and I would highly recommend Capitol Plumbing & Heating of Santa Fe for all your plumbing needs.
