By Rub-A-Dub Plumbing | East Texas Home Tips
This is one of the most common questions we get, and also one of the most commonly misanswered online. You will find articles quoting national averages that have little bearing on what a real job in East Texas actually costs — and you will find contractors quoting minimums on the phone that bear little resemblance to the final invoice.
We are going to give you the real numbers, explain what drives them, and tell you what to watch out for.
The Short Answer
For most Rub-A-Dub customers replacing a standard tank water heater in East Texas, the total installed cost falls between $2,600 and $4,500. The most common job lands around $3,100. That includes the unit, professional installation, haul-away of the old heater, and all standard components.
If you are upgrading to a higher-efficiency system — tankless gas, heat pump electric, or a deluxe installation package with extended warranty coverage — the range moves higher. We will break those down below.
Standard Tank Replacement (Gas or Electric)
A straightforward like-for-like tank replacement is what most calls turn out to be. The homeowner has a failed or aging unit, we swap it for a comparable new model, and the job is done in a few hours.
Typical range: $2,600 – $4,500. Most common cost: around $3,100.
What pushes toward the higher end of that range: the existing gas line or electrical circuit needs updating to meet current code, an expansion tank is required (increasingly common with modern pressure-reducing valve systems), or the installation location is difficult to access. None of those are unusual — they just add time and materials.
What is included in a quality installation: the new unit, professional installation, haul-away and recycling of the old heater, a new T&P valve, supply line connections, and all required components. If a contractor is quoting you a number that seems to cover only labor and the unit itself, ask what is not included.
Deluxe Installation with Extended Warranty Coverage
For homeowners who want long-term protection, we offer installation packages that include an expansion tank, ball valve, fast-drain valve, catch pan, and extended labor warranty coverage — up to 10 years on the tank and 5 years on parts and labor for deluxe units.
Typical range: $3,300 – $5,500. Most common cost: around $4,000.
This is the most popular option among customers who plan to stay in their home for a decade or more. The added components protect the unit, and the extended warranty means that if something does go wrong, you are covered without another service call bill.
Tankless Gas Water Heater
Tankless installation is more involved than a tank swap — the gas line almost always needs to be upsized, dedicated venting has to be run, and the old tank unit needs to be removed and disposed of. It is a larger project, and the pricing reflects that.
Typical range: $4,900 – $8,500. Most common cost: around $6,200.
The long-term math can favor tankless for the right household — better energy efficiency, continuous hot water, and a lifespan of 20 years or more. But the higher upfront cost is real, and it is not the right call for every situation or every home’s existing infrastructure.
Heat Pump (Hybrid Electric) Water Heater
Heat pump units are the most energy-efficient electric option available, and East Texas’s mild climate makes them a genuinely good fit. The installation requires adequate space, a compatible electrical circuit, and ceiling clearance for the taller unit profile.
Typical range: $6,700 – $13,500. Most common cost: around $9,000.
Federal tax credits for qualifying heat pump water heater installations are currently available — worth checking with your tax advisor on what applies to your situation.
What the Online Quotes Are Usually Missing
The low numbers you see advertised — $800, $1,200, sometimes lower — are almost never all-in prices. They typically exclude the expansion tank, the catch pan, updated supply lines, haul-away fees, permit costs where required, and any code updates the existing setup needs. By the time those are added, the invoice looks very different from the quote.
We price jobs to include what the job actually requires. That means our upfront number is sometimes higher than a competitor’s opening quote — and our final invoice matches what we said it would be.
Every home is a little different. If you want a straight answer on what your specific replacement would cost, give us a call. We are happy to walk through it with you before anyone commits to anything.
Bottom Line
A quality water heater installation in East Texas costs between $2,600 and $4,500 for most standard jobs, with higher-efficiency systems running more. The variables are real — the unit type, the existing infrastructure, the warranty tier, and what the installation actually includes all affect the final number.
What should not vary is whether the number you are given upfront matches the invoice you receive at the end. That is the standard we hold ourselves to.
