Tankless Water Heater Installation, Repair, and Replacement

Access to instantaneous hot water defines the comfort of a high-functioning South Carolina home. While traditional storage tanks keep 50 gallons of water hot 24 hours a day, a tankless system only activates when you turn on a tap. This shift from batch heating to on-demand flow eliminates the frustration of running out of hot water during back-to-back showers. Preferred Home Services specializes in the total lifecycle of these plumbing units, focusing on precision thermal exchange and maximum energy conservation.

Upgrade your home to a limitless supply of hot water by requesting a professional system consultation today.

Strategic System Installation and Seamless Unit Replacement

Moving from a bulky tank to a wall-mounted on-demand system requires more than just a pipe connection; it requires a calculated understanding of your home’s peak Gallons Per Minute (GPM) demand. Our team handles the entire transition, ensuring your new heating unit is perfectly matched to your family’s actual water usage.

  • Lowering monthly utility overhead occurs when we install high-efficiency units that only consume gas or electricity during active use.
  • Maximizing indoor square footage is a major benefit of replacement, as these compact units free up significant space in closets or garages.
  • Modernizing fuel and venting logistics ensures that your gas lines and exhaust pipes meet current safety standards for high-output burners.
  • Doubling equipment lifespan occurs when we replace 10-year storage tanks with tankless technology designed to last up to 30 years.

Our master plumbers prioritize a clean and professional setup that treats your home’s utility room with the same respect as a finished living space.

Precision Mechanical Repair and Thermal Restoration

A lack of heat or a drop in water volume often indicates a specific mechanical issue within your tankless unit. We approach every repair with a focus on restoring the fire-to-flow ratio, ensuring the internal heating elements engage as needed.

  • Isolating ignition failures to the sensors and spark electrodes can prevent the unit from firing.
  • Neutralizing temperature fluctuations addresses the internal calcification that interferes with the heat exchanger’s performance.
  • Identifying unusual vibration or noise helps prevent mechanical wear from causing a total system lockout.
  • Sealing internal supply leaks protects the sensitive circuit boards and electrical components housed inside the unit.

Every repair visit includes a comprehensive evaluation of your unit’s internal filters and safety bypass valves to ensure reliable operation during your busiest times of the day.

Proactive Descaling and Long-Term Efficiency Maintenance

The primary enemy of an on-demand heater is the mineral content found in the local water supply. Over time, calcium builds up on the heat exchanger, creating a barrier that forces the unit to work harder and run hotter. Our annual maintenance protocols include a high-velocity flush to remove these deposits and preserve your manufacturer’s warranty.

By joining our Preferred Partner Plan, you secure a scheduled defense against efficiency loss. We do not just check the unit; we perform a forensic cleaning of the burner assembly and intake filters to help keep your utility bills as low as possible.

The tech, Adam, took a few minutes to establish a rapport with me before getting down to business and checking out my a/c unit. He found that the compressor was pulling too much current at startup. He took care of it and showed me the difference on his meter. He also took care of one other minor issue.

Chase did a great job cleaning the blower motor of our unit! Took motor out and cleaned and disinfected it! Well worth the money! He also is super pleasant to deal with - such a calm nature that by dogs did not even bark once the whole time he was there. Hole if I need this service again , he will still be available!

Had Preferred Home Services out for a major plumbing project — new Navien tankless, Halo H2zero Ultimate whole-house filtration, Caleffi pressure-reducing valve, and a sediment polishing filter. From the initial diagnosis with Maddie to the install crew on the day of, the whole experience was professional and thorough. Maddie took the time to walk through every issue — vibrating PRV, undersized tankless, low pressure, and sediment — and laid out options without pressure. The install crew showed up on time, worked clean, and the finished plumbing layout is genuinely well done. They added isolation ball valves throughout, which means I'll never have to shut down the whole house for routine filter changes or service. That's the kind of detail that separates a real plumber from a parts-swapper. The hot water delivery is dramatically better, pressure is finally where it should be, and the kitchen faucet that used to take two minutes for hot water is now near-instant. Pricing was fair for the quality of equipment and workmanship, and the bundling made the math work. Will absolutely use them again. Ask for Maddie

Jacob, Chris, and Mac (and the entire rest of their team) absolutely worked like madmen to completely re-plumb my 1066 house. They had their work cut out for them, yet they seemed to enjoy every moment of it. Seldom have I experienced such great work ethic across a whole team of individuals. 5 stars plus some. Bravo, gentlemen, and thank you for fixing my house! 🙏🏻🙏🏻🙏🏻
