Water heater replacement cost in the Upstate
Water heater replacement is one of the more predictable plumbing costs you will face. The big variable is whether you stay with a tank or switch to tankless, and whether a tankless switch needs new gas and venting.
Standard tank (like-for-like)
Like-for-like 40 to 50 gal gas or electric tank, standard install and haul-away.
Full range $900 to $2,500.
Switching to tankless
A new gas line or venting pushes toward the top of the range. This is the biggest swing variable.
Wide range, needs an inspection to price.
Full range $1,400 to $5,600.
What drives the price
Two jobs that sound the same can price very differently. Access, urgency, permits, parts, and the condition of the existing system do most of the work. Greenville and the Upstate run a bit below national pricing, so these ranges already lean local.
When to call a pro
A tank leaking from its body, rather than a fitting, almost always means replacement rather than repair.
