About This Service
At H3 Plumbing & Drains, we provide reliable, high-quality water heater services for residential and commercial customers across Spartanburg, SC. We service all major brands including Rheem, Rinnai, Bradford White, Bosch, AO Smith, and Navien. Whether you're dealing with no hot water, inconsistent temperatures, rust-colored water, or a leaking tank, our licensed technicians will diagnose the problem and deliver The Most Correct Solution. Spartanburg County's mineral-heavy water supply accelerates sediment buildup inside tank water heaters, shortening their lifespan and reducing efficiency. We flush tanks, replace anode rods, and service heating elements to extend the life of your unit — and we'll tell you honestly when repair no longer makes financial sense and replacement is the smarter move.

Types of Water Heaters
Electric
Electric water heaters use heating elements to warm water inside an insulated tank. They're simple to install, don't require a gas line or venting, and are a great fit for homes without natural gas. State water heaters and Rheem are reliable brands for electric tank installs in a range of capacities. We install, repair, and replace electric units of all sizes.
Gas
Gas water heaters use a burner to heat water quickly and tend to cost less to operate where natural gas is available. They recover faster than electric units, making them ideal for larger households with higher hot water demand. American water heaters and Rheem are popular choices for dependable gas tank systems. We handle full installation, venting, and repairs.
Tankless
Tankless (on-demand) water heaters heat water only when you need it — no standby heat loss and no bulky tank. They deliver a continuous supply of hot water, last 20+ years, and save space and energy. Rinnai and Navien are the brands we most commonly install for tankless systems. We size, install, and service tankless units from all major brands.
Should You Repair or Replace?
The right answer depends on the unit's age, the cost of the repair, and your hot water demand. Here's how we think about it:
Repair makes sense when…
- The unit is under 8 years old
- The repair is a single, minor component (element, thermostat, anode rod)
- The tank itself shows no signs of corrosion or sediment cracking
- The repair cost is less than 40% of a new unit's installed price
Replace makes sense when…
- The unit is 10–12+ years old (tank) or 15+ years (tankless)
- Repairs have happened more than once in the past 2 years
- The tank is rusting, leaking from the base, or showing sediment damage
- Energy bills have risen and the unit is undersized for your household

Frequently Asked Questions
Should I repair or replace my water heater?
If your water heater is under 8 years old and the repair is minor, repair often makes sense. If it's over 10–12 years old or repairs are recurring, replacement is usually more cost-effective. We'll give you an honest assessment either way.
What are the benefits of a tankless water heater?
Tankless (on-demand) units heat water only when needed — no standby heat loss. They last 20+ years (vs. 8–12 for tank units), provide unlimited hot water, and are more energy-efficient. The upfront cost is higher but pays back over time.
My water heater is leaking — is this an emergency?
Yes, treat it as one. A leaking water heater can fail completely and flood your space. Shut off the cold water supply to the tank and call us immediately.
