A new water heater is a ten-year decision installed in a day. Whether it is a first install, a planned replacement before the old tank fails, or a swap after it already did — describe the home and get connected with a professional who installs tank water heaters across South Carolina.
Phone only — no forms. How calling this number works

Water heater installation in South Carolina — this page covers both doors into the same job: a first-time installation (a new setup, a conversion, an added unit) and a replacement (an existing tank coming out, a new one going in its place). Most calls are replacements, and the quality of the job is decided long before the tank is lit: sizing, fuel and venting checks, and the unglamorous parts — drain pan, expansion tank, shutoffs. Call (844) 791-1083 and describe your current unit.
The tank itself is the easy part. These six decisions around it decide how the next decade of hot water goes.
Forty, fifty or seventy-five gallons is household math — people, bathrooms and the morning peak. Professionals size by first-hour rating against your busiest hour, not by what the old tank happened to be.
What the home already runs usually leads, because switching fuels adds venting or electrical work to the job. Staying with the existing fuel keeps a replacement simple; switching is a project worth planning.
Atmospheric, power-vent and direct-vent units are not interchangeable — the new tank’s venting has to match the home’s flue reality. A wrong vent match is a safety item, not a detail.
Garage, attic and closet installs carry different leak consequences, and the drain pan plus its drain route are sized to that. Attic installs deserve the most careful version of this conversation.
On modern closed plumbing systems, an expansion tank protects the new heater — and the home’s other fixtures — from pressure swings. Healthy water pressure is checked as part of a proper install.
Many South Carolina cities and counties require a permit, and sometimes an inspection, for a water heater install — and details like T&P discharge routing and, near the coast’s seismic zone, strapping are part of doing it properly.
Swapping the tank is the middle of the job, not the whole of it:
The old tank is drained safely and its fuel — gas or electric — isolated before anything is unhooked.
The old unit comes out. Confirm beforehand what happens to it, so it is not sitting in your garage afterward.
The new tank is leveled on its pan; water, fuel and venting connected; expansion tank and new shutoffs fitted.
The tank is filled before power or gas is restored — a dry-fired element dies in seconds — then connections are leak-checked and temperature set, conventionally around 120°F.
If a quote sounds like it is only for the tank itself, ask what else is included — pan, expansion, shutoffs, permit and haul-away are where honest quotes differ. Describe your current unit when you call: (844) 791-1083.


A planned replacement is a different experience from an emergency one. Planned, you choose: the size, the fuel, possibly the switch to tankless, and a day that suits the household. The signs that the planned window is open are consistent — the tank is past ten years old, rust is showing at the base or in the water, rumbling has started, or repairs are beginning to stack up.
After a failure, speed matters and choices narrow to what fits the space and can be installed now — which is still a perfectly normal job, just a less leisurely one. Either way, the work itself is the same careful sequence. The only genuinely bad timing is the leak that was watched for months: water damage costs more than any tank.
Current unit — size, fuel, age — where it sits, and whether this is planned or the old one has already failed.
Unit, fittings, permit handling and old-unit removal agreed before the work starts.
Old out, new in, connected, filled and checked — with the safety parts fitted, not promised.
Your shutoffs, T&P valve, temperature setting and the maintenance rhythm pointed out before the professional leaves.

If the tank body is dry and sound and the fault is an element, thermostat, valve or igniter, repair is often the smarter spend — the tank repair page covers that side. Ask the professional for the honest comparison between fixing yours and replacing it; a good one will show you the tank’s condition and give you both sides of the line.
Installs run statewide through local professionals — the same network behind this site’s city hub pages. If your town has a hub page, the local detail lives there; if not, one call still reaches a professional who covers your ZIP.
