When a failed water heater is an emergency
Most tanks do not fail politely. They leak slowly for a while, then let go and put several gallons on the floor. If that is happening now, close the cold water valve on top of the heater and turn off its breaker or gas control. Then call (630) 822-9290 and tell us what you see. Call (630) 822-9290
Gas smell means leave first
If a gas water heater has caused a gas smell, leave the building right away and take everyone with you. Call the Nicor Gas emergency line or 911 from outside. Do not turn switches on or off on your way out. Call us after the gas company or fire department says it is safe to go back in.
Not every cold shower means a replacement. A bad thermostat or a worn thermocouple is a repair, and we will say so honestly. Our water heater repair page covers those cases. If the tank itself is rusted through, though, a new heater is the only lasting answer.
Signs your tank has reached the end
A water heater gives warning signs before it fails completely. The ones that matter most are water around the base, rust-colored hot water, loud popping from sediment and a tank that is well past its expected years. Hot water that runs out faster than it used to is another clue.
A tank that is 15 years old and corroded is the textbook case. Its shell has been working against rust for years, and one more cold winter can finish it. Replacing it on your schedule is much easier than doing it with a flooded basement.
If your tank is leaking from the tank body, no fitting fixes it. If it is leaking from a pipe connection or valve, a repair may still make sense. We check before we recommend anything.
What happens when a basement floods
Water heaters in Hoffman Estates basements and utility rooms are often next to a floor drain, a furnace and a panel. A failed tank can soak all of them. If the water is deep or near the electrical panel, stay out and call a licensed electrician or the utility before going near it.
After a flood, a gas water heater that sat in water needs a careful look at the burner, gas control and venting. A unit that was submerged is often better replaced than restarted. We evaluate that on site and tell you what we find before you decide. Call (630) 822-9290
If the water came from somewhere else, such as a storm or a sump pump failure, our sump pump repair page covers that side of the problem.
Choosing the new heater: gas, electric or hybrid
Most homes replace like with like, because the gas line, venting, electrical circuit and plumbing already match. Switching fuel is possible, but it changes the scope and the cost. Moving from gas to a heat pump unit, for example, involves electrical work, space for airflow and a drain for condensate.
| Option | Good fit when | Trade-off |
|---|---|---|
| Standard gas tank | Gas line and vent are in place | Needs proper venting and combustion air |
| Power-vented or condensing gas tank | You want higher efficiency | Needs electrical outlet and drain for condensate |
| Standard electric tank | No gas service, simple setup | Higher running cost in many homes |
| Hybrid heat pump tank | You want lower electric use | Needs space, airflow and a condensate drain |
| Tankless | You want endless hot water | Different venting, gas or electric load, and flushing |
If tankless sounds right for you, see tankless water heater for what changes. If you are planning rather than reacting, water heater installation covers the setup side in more detail.
Sizing and capacity
A tank that is too small runs out during back-to-back showers. One that is too large costs more to buy and to keep hot. We size by household use, how many bathrooms you have and how fast the unit recovers, not by what happened to be on the shelf.
Tell us how many people live in the house and how you use hot water. A family with a soaking tub and a dishwasher running at the same time has different needs than a couple in a small ranch. We will look at the old label and the space before recommending a capacity.
Permits and inspections in Hoffman Estates
Water heater work in the village is permitted. The Village of Hoffman Estates has a handout covering new, repair and replacement water heaters, and the Village fee handout lists $50 for a water heater permit. Permits and inspections are requested through the Village's online portal.
The Village inspector looks for specific things. These include a shut-off valve on the cold supply within 5 feet of the heater in the same room, a relief valve with a full-size metal discharge pipe ending 2 to 6 inches above the floor, and listed flexible connectors. Plastic pipe is not allowed for the relief discharge.
For gas heaters, the handout calls for screwed flue joints, a secured draft diverter and contractor certification of the flue. Closet installations need combustion air openings top and bottom. A gas heater in a garage needs its burners at least 18 inches off the floor. The Village does not do same-day inspections, so the final inspection is scheduled after the swap. (630) 822-9290
According to the Village handout, a closet install needs combustion air openings of 100 square inches at the top and the bottom. A closet fitted with a solid door and no openings has to be addressed before the new gas heater can be lit.
Emergency repair work needs a permit submitted within 24 hours after work begins. That is why a hot water emergency can still be handled properly, and the paperwork follows. Ask us on the call how it fits your situation.
Nicor Gas rebates in 2026
If you are replacing a gas heater, there may be money back. For 2026, the Nicor Gas Energy Efficiency Program lists $150 for a tankless water heater meeting its efficiency rules and $150 for a power-vented or condensing storage heater that meets its own rule. Work must be installed between January 1 and December 31, 2026.
The application deadline is within 90 days of installation or by January 31, 2027. Rules and eligibility are set by Nicor Gas, so check their rebate page or call 877-886-4239 before you buy. We can tell you whether the unit you are considering is the type those programs target. Call (630) 822-9290
What the day looks like
We confirm the size, fuel and venting on the phone, then plan the swap around what your home needs. On site, we shut off the water and power or gas, drain the old tank and disconnect it. The new unit goes in with a fresh shut-off, relief valve and discharge pipe set to the Village conditions.
Gas units are leak-tested at the connections and the flue is checked for proper draft before we leave. Electric units are checked for correct wiring and a full tank before power is restored. We haul away the old heater, and we show you the shutoffs so you know where they are next time.
A burst pipe or a leak that shows up after a new heater goes in is not normal. If water appears near connections after any water heater swap, shut the water off and call us. Our burst pipe repair page explains what to do first.
What changes the price
We quote the price by phone before work starts, once you tell us the fuel type, size and location of the heater. If the plumber finds a code issue or a bad shut-off on site, we explain it and get your approval first. (630) 822-9290
Water heater replacement questions
Yes. We take calls 24/7, including nights and weekends. Call, and we will walk you through shutting off water and power while we arrange the work.
Close the cold water valve on the heater and turn off its power. If you smell gas, leave the house and call the Nicor Gas emergency line or 911 before calling us.
Water leaking from the tank body, rusty hot water and an old, corroded tank point to replacement. A bad part on a newer tank often means repair.
Yes, the Village has a water heater permit with a final inspection. The Village fee handout lists $50, and we can explain the steps when you call.
Nicor Gas lists $150 rebates in 2026 for qualifying tankless and power-vented or condensing gas heaters. Check Nicor's current rules before you buy.
Often yes, but it changes the electrical, venting and space needs. We will go over what your home needs before you commit.
Not always. A gas unit that sat in water needs its burner, controls and venting checked, and many are better replaced.
Many replacements are done in a single visit. Moving vents, changing fuel or fixing old piping can add time, and we will tell you up front.
If your tank has failed, Call (630) 822-9290 and we will start with the shutoff steps. If you would rather plan ahead, read about water heater installation or call (630) 822-9290 with your questions.
