Short answer
Replacing a standard tank water heater in Central Texas typically costs $2,100–$3,000 installed, including the new unit, labor, fittings, and haul-away of the old tank. Tankless replacements usually start around $4,100 for gas and run $2,500–$4,000 for electric.
Replacing a water heater in Texas costs $2,100–$3,000 for a standard tank and $4,100 or more for a whole-house gas tankless unit, installed. What moves the price within those ranges is the type of unit (tank vs. tankless), the capacity you need, and the fuel source (gas vs. electric). Here is the full breakdown for 2026, including what is and isn't included in an installed price.
| Water heater type | Typical application | Installed cost |
|---|---|---|
| Tank, 40 gallon | 1–2 bathrooms | $2,100–$2,500 |
| Tank, 50 gallon | 2–3 bathrooms | $2,100–$2,700 |
| Tank, larger or complex install | Venting, access, or code work | Up to $3,000 |
| Tankless, gas (whole house) | Whole home, high flow | From $4,100 |
| Tankless, electric (whole house) | Whole home, needs panel capacity | $2,500–$4,000 |
| Tankless, point-of-use | One fixture | $500–$1,200 |
| Heat pump (hybrid) | Whole home, lowest operating cost | $2,000–$3,500 |
Tank Water Heater Installation: $2,100–$3,000
A standard tank water heater is still the most popular choice for Central Texas homes. The unit stores 40–75 gallons of hot water and keeps it at temperature around the clock. When your old tank dies, replacing it with a new one of the same type is usually straightforward.
40-gallon tank (1–2 bathrooms): commonly $2,100–$2,500 installed. This size works for 1–2 person households. It's the most affordable standard tank option and usually fits in the same footprint as your existing unit.
50-gallon tank (2–3 bathrooms): commonly $2,100–$2,700 installed. The most common size for Central Texas homes. Handles a family of 3–4 people with typical usage - showers, dishwasher, laundry.
Larger or more complex tank replacements: up to about $3,000 installed. Larger households, difficult access, fuel or venting changes, and code upgrades can push a standard tank replacement toward the top of the range.
These prices include the water heater, standard installation, haul-away of the old unit, and all fittings and connections. If additional work is needed - like upgrading a water line, moving the unit to a new location, or bringing the installation up to current building code - that adds to the cost.
Tankless Water Heater Installation: Often $4,100+
Tankless (on-demand) water heaters heat water as it flows through the unit rather than storing it. They take up much less space, last 15–20 years (compared to 8–12 for a tank), and use 8–34% less energy because there's no standby heat loss.
Whole-house gas tankless: commonly starts around $4,100 installed. Gas tankless units produce higher flow rates and can handle multiple fixtures simultaneously. However, retrofitting from a tank to a gas tankless often requires upgrading the gas line (from 1/2 inch to 3/4 inch) and installing new venting - both of which add to the cost.
Whole-house electric tankless: $2,500–$4,000 installed. Electric tankless units are simpler to install but require significant electrical capacity - often a dedicated 200-amp panel and multiple 40-amp breakers. If your home's electrical panel needs upgrading, that's an additional cost.
Point-of-use tankless: $500–$1,200 installed. These small units serve a single fixture - like a bathroom sink or a kitchen faucet far from the main water heater. They're useful for eliminating the long wait for hot water at distant fixtures.
Gas vs. Electric: Which Costs More?
Gas water heaters have a lower operating cost in Texas because natural gas is relatively cheap here. A gas tank unit costs about $25–$35/month to operate. The upfront cost is slightly higher because of venting requirements, but you save on your monthly utility bill.
Electric water heaters are cheaper to purchase and install (no venting needed) but cost more to operate - roughly $40–$55/month in Central Texas. They're a good choice for homes without a gas line or for locations where venting is impractical (like an interior closet).
Heat pump water heaters are the most efficient option - they use about 60% less energy than a standard electric tank. Installed cost is $2,000–$3,500, but federal tax credits and energy savings can offset the premium within a few years. They need to be installed in a space with adequate airflow (not a tiny closet) because they pull heat from the surrounding air.
Size Chart: How to Choose the Right Capacity
1–2 people: 30–40 gallon tank, or a tankless unit rated for 2–3 GPM.
3–4 people: 40–50 gallon tank, or a tankless unit rated for 4–5 GPM.
5+ people: 50–75 gallon tank, or a tankless unit rated for 6+ GPM (or two smaller tankless units in parallel).
Undersizing is one of the most common water heater mistakes. If you consistently run out of hot water, the unit is too small for your household. Oversizing wastes energy because you're keeping more water hot than you need.
What's Included in a Kimco Installation
When you get a water heater installation from Kimco, the flat-rate price includes removal and disposal of the old unit, the new water heater, all necessary fittings, connections, and valves, a new expansion tank (required by Texas code), testing and commissioning, and cleanup. If any additional work is needed (gas line upgrade, electrical work, relocating the unit), we'll identify that during the estimate and include it in the quote - no surprises after the job starts.
Should You Repair or Replace?
Repair usually makes sense when the tank is still sound and the failed part is replaceable. Replacement becomes the better investment when the tank is leaking, badly corroded, repeatedly failing, or already near the end of its expected life. Compare the diagnosis with the complete installed replacement price rather than deciding from age alone.

Frequently Asked Questions
How much does it cost to replace a water heater in Texas?+
A standard tank water heater replacement in Central Texas runs $2,100–$3,000 installed. That covers the new unit, standard installation, all fittings and connections, and haul-away of the old tank. Whole-house tankless replacements start around $4,100 for gas and $2,500–$4,000 for electric.
How much does a 50-gallon water heater cost installed?+
A 50-gallon tank water heater commonly costs $2,100–$2,700 installed. It is the most common size for Central Texas homes and handles a family of three to four people with typical shower, dishwasher, and laundry use.
Is a tankless water heater worth the extra cost?+
It depends on how long you plan to stay in the home. A whole-house gas tankless unit starts around $4,100 installed versus $2,100–$3,000 for a tank, but it lasts 15–20 years instead of 8–12 and uses 8–34% less energy because there is no standby heat loss. Over a full lifespan the difference often evens out; over five years it usually does not.
Is a gas or electric water heater cheaper to run in Texas?+
Gas is cheaper to operate in Texas. A gas tank unit costs roughly $25–$35 per month to run, compared with $40–$55 per month for a standard electric tank. Electric units are cheaper to buy and install because they need no venting, so the better choice depends on whether the home already has a gas line and a vent.
Does the installed price include removing the old water heater?+
Yes. A Kimco flat-rate water heater price includes removal and disposal of the old unit, the new water heater, all necessary fittings and connections, and testing. Work beyond a like-for-like swap — relocating the unit, upgrading a water line, or bringing an older installation up to current code — is quoted separately before it begins.
How long does a water heater replacement take?+
A like-for-like tank replacement is usually a same-day job. Switching from tank to tankless takes longer because it can require new venting, a gas line upgrade, or added electrical capacity. Kimco confirms the scope and the flat-rate price on-site before starting.
