Tankless Water Heaters in Highland Park, IL
Endless hot water and a unit on the wall instead of a tank on the floor. We install, repair and descale tankless water heaters, and we'll tell you honestly whether your home is a good fit before you spend anything. Now with an office on Green Bay Road.
How a Tankless Water Heater Works
A tankless water heater heats water only when you open a hot tap. Water runs through a heat exchanger, a gas burner or electric element heats it on the spot, and it flows to the fixture. There's no tank to keep hot around the clock, so you don't run out halfway through a shower. The tradeoff is that the unit has to be sized for how much hot water you use at the same time, and it needs the gas supply, venting or electrical service to match.
Tank vs. Tankless: Which Fits Your Home?
Neither one is right for every home. Here's how they compare:
| Tank Water Heater | Tankless Water Heater | |
|---|---|---|
| Hot water supply | Limited to the tank size | Continuous, up to the unit's flow rate |
| Space | Floor space for the tank | Mounts on the wall |
| Typical lifespan | About 8 to 12 years | Often longer with regular descaling |
| Install requirements | Usually a straight swap | May need a larger gas line, new venting or electrical upgrades |
| Maintenance | Annual flush | Regular descaling |
We'll look at your household, your gas or electric service and your venting before recommending either.
Tankless in Older Highland Park Homes
Nearly half of Highland Park homes were built before 1960. Tankless can be a great upgrade, but older homes need a closer look first.
Gas Line Capacity
A gas tankless unit often needs more gas than the old tank did. In older homes, that can mean upsizing the line. See gas line installation.
Venting and Electrical
Tankless units vent differently from tank heaters, and electric models can need a panel upgrade. We check both before we quote, so you don't find out halfway through the job.
Winter Flow Rates
In a Lake County winter, incoming water is much colder, so the unit has to heat it further. We size tankless units for winter, when they have to work hardest.
