When Is It Time to Replace Your Tank Water Heater?
Most tank water heaters in the Chicago area last 8 to 12 years. These are the signs it is time to replace rather than repair.
- The tank is leakingWater at the base of the tank usually means the inner tank has rusted through, and that cannot be repaired.
- It's 10 to 12 years oldTanks in this age range are near the end of their typical life, so a major repair rarely makes sense.
- Rusty or discolored hot waterRust in the hot water often points to a corroding tank or a spent anode rod.
- Not enough hot waterIf the household has grown or showers run cold, a larger tank or faster recovery may be the answer.
- Popping or rumbling noisesSediment buildup makes the burner work harder and shortens the life of the tank.
- Repairs keep repeatingWhen the gas valve, thermocouple or burner parts keep failing on an older tank, replacement is usually the better value.
Safety first! Every gas tank replacement includes checking the venting, draft, gas connections and the temperature and pressure relief valve before we leave.
How We Replace a Tank Water Heater
A tank swap looks simple, but the details decide how long the new one lasts and how safely it runs.
- Size for your household. We match tank size and recovery to your household: roughly 40 gallons for 1 to 2 people, 50 for 3 to 4, and 75 for larger families.
- Check venting, gas and water lines. We confirm the chimney or flue, gas piping, water connections, shut-off valve and drain pan, and whether a slim, tall or short tank fits the space.
- Complete the installation. Our in-house team removes and hauls away the old tank and completes the water, gas or electrical, vent and safety connections.
- Start up and verify. Startup confirms burner operation, draft, temperature setting and leak-free connections before the walkthrough.
Repair, Standard Tank or Power-Vent Replacement?
Choose a standard tank when the existing chimney venting is safe and adequate, and a power-vent tank when it is not. When replacement is required, the best choice depends on more than matching the old configuration.
The existing venting supports it
If the current vent arrangement remains appropriate, a conventional atmospheric tank is often the simpler and less expensive project.
Venting is the limiting factor
When the vent route, chimney condition or equipment location is the constraint, power venting opens up options a standard tank cannot.
THE FOUR THINGS WE WEIGH
Household hot-water needs
Peak use, fixture count and recovery rate determine the capacity before anything else is decided.
What the venting allows
Chimney condition, vent material and length, and combustion air decide whether a standard atmospheric tank still fits.
Gas or electric
Gas supply and piping for gas tanks, or the right circuit for electric tanks.
Room to install and service
Clearances, drainage and future service access in the mechanical room.

We install Bradford White tank water heaters, made in the USA, and Navien condensing tankless water heaters. Here's how the options compare, from a simple tank swap to endless hot water.

- Fixes orphaned-chimney problems
Navien Tankless
Heats water on demand, so you never run out. Ultra-high-efficiency condensing design that frees up floor space.

Tank Water Heater FAQs
What size tank water heater do I need?
Roughly 40 gallons for 1 to 2 people, 50 gallons for 3 to 4 and 75 gallons for larger families. Large soaking tubs, several showers running at once and fast recovery needs can push the size up, so we look at how your household uses hot water before recommending a tank.
How much does a tank water heater cost?
A standard 40-gallon tank water heater typically costs $1,600 to $2,000 installed, a 50-gallon $1,700 to $2,200 and a 75-gallon $2,700 to $3,300. The brand, gas or electric, a slim, tall or short tank, a new drain pan or ¾-inch main shut-off valve, venting changes, gas piping and copper or galvanized water lines set the final price. You get a written price before any work starts.
What is included with a tank water heater installation?
Every standard tank installation includes the new Bradford White water heater, removal and disposal of the old one, new dielectric unions, a new temperature and pressure relief valve with discharge piping to code, and reconnection of the gas, vent and hot and cold water lines. We add a new gas shut-off valve, vent connector or drain pan when the location needs one, then fill and purge the system, verify draft, leak-test every water and gas connection and complete a full startup and safety check.
What warranty comes with a new tank water heater?
Standard Bradford White tanks come with a 6-year manufacturer warranty on the tank and parts, and Pure Comfort adds a 1-year labor warranty on the installation.
How long does a tank water heater last?
Most tank water heaters in the Chicago area last 8 to 12 years. Flushing sediment and checking the anode rod can help a tank reach the upper end of that range.
Should I choose a gas or electric tank?
We install both. Most homes here already have a gas tank, and replacing gas with gas or electric with electric is the simplest project. Switching fuel types means adding gas piping and venting or a dedicated electrical circuit, and we price that out before you decide.
How quickly can you replace a tank water heater?
We stock 40- and 50-gallon tanks for fast replacement. 75-gallon tanks and slim, tall or short models may need to be ordered, and we tell you the timing when we quote the job.
Do you haul away the old water heater?
Yes. Removing and hauling away the old tank is part of every water heater installation.
Is financing available for a tank water heater?
Water heater projects over $2,000 can be financed with longer terms for a lower monthly payment, subject to credit approval. That includes 75-gallon tanks and many 50-gallon replacements.
How often should a water heater be maintained?
Once a year. A tank water heater should be flushed yearly to clear sediment, with the anode rod checked every few years. A tankless water heater should be descaled about once a year, more often with hard water. We can do either during a service visit.
