Element Service Group installs, services, and repairs Rinnai tankless water heaters across Apex, Cary, Raleigh, and the wider Triangle, with NC-licensed master plumbers and genuine Rinnai parts.
Rinnai Tankless Water Heaters, Installed and Serviced Across the Triangle
Rinnai is a Japanese manufacturer and one of the largest makers of on-demand gas water heaters in the world, with a U.S. manufacturing facility in Griffin, Georgia. The brand is known for endless hot water, compact wall-mounted units, and high energy efficiency, including ENERGY STAR qualified models. For Triangle homeowners who are tired of running out of hot water or want to reclaim the floor space a traditional tank takes up, a Rinnai tankless system is a proven option.
Element Service Group installs, services, and repairs Rinnai tankless water heaters throughout the Triangle. We are an independent service provider, not a factory-authorized dealer, and our work is performed by NC-licensed master plumbers (Class 1) using genuine Rinnai parts. Rinnai is an established brand for our team, so the units we put on your wall are systems we know inside and out.
We handle the full lifecycle: new installation, tank-to-tankless replacement, recirculation setup, venting and gas line work, annual descaling, and repair and diagnostics. Because much of the Triangle has hard water, regular descaling matters more here than in soft-water regions, and we build that maintenance into how we care for every Rinnai unit we touch.

Why Choose Rinnai?
Endless on-demand hot water
Rinnai units heat water as it flows, so a properly sized system keeps hot water coming through long showers, laundry, and dishes without the wait for a tank to recover.
Compact, wall-mounted footprint
Tankless units mount on the wall and free up the floor space a conventional tank occupies, which is useful in Triangle homes with tight garages, closets, or crawlspace mechanical areas.
High energy efficiency
Rinnai condensing models reach high Uniform Energy Factor ratings and include ENERGY STAR qualified options, heating water only on demand instead of keeping a full tank hot around the clock.
NC-licensed master plumbers
Every Rinnai installation and repair is performed by NC-licensed master plumbers (Class 1), so the gas, venting, and water connections meet code and the manufacturer's requirements.
Hard-water descaling built in
Many Triangle areas have hard water that leaves scale inside heat exchangers. We perform annual descaling and flushing to protect efficiency and extend the life of your Rinnai unit.
Genuine Rinnai parts
As an independent service provider, we install, service, and repair Rinnai equipment using genuine manufacturer parts so components fit and perform as designed.
Frequently Asked Questions About Rinnai
Does Element Service Group install and repair Rinnai tankless water heaters?
Yes. We install, replace, service, and repair Rinnai tankless water heaters across the Triangle. We are an independent service provider rather than a factory-authorized dealer, and our work is done by NC-licensed master plumbers using genuine Rinnai parts. Rinnai is an established brand for our team, so it is a system we work on regularly.
How often should a Rinnai tankless unit be descaled in the Triangle?
Because much of the Triangle has hard water, we generally recommend descaling and flushing once a year. Hard water leaves mineral scale inside the heat exchanger, which reduces efficiency and flow over time. Annual descaling keeps the unit running the way Rinnai designed it and helps it last.
Can you convert my existing tank water heater to a Rinnai tankless system?
Yes. Tank-to-tankless conversions are a common job for us. The work usually involves new venting, possible gas line upsizing, and updated water and electrical connections. Our master plumbers assess your home, size the unit to your hot water demand, and handle the full installation to code.
What is recirculation, and can you set it up on a Rinnai unit?
Recirculation keeps hot water moving so it arrives faster at fixtures far from the heater, which cuts down on the wait and the water you run off. Rinnai offers recirculation technology such as Circ-Logic, and select models include built-in recirculation. We can set up and configure recirculation as part of an installation or as an upgrade.
