Tankless Water Heaters in Northbrook, IL
Endless hot water for a busy household 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 if your home is a good fit before you spend anything. From our Techny Road headquarters.
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.
Is Tankless Right for Your Northbrook Home?
Tankless can be a great upgrade for a busy Northbrook household. Whether it works in your home comes down to three things we check before quoting.
Gas Supply for a Bigger Burner
A gas tankless unit can need far more gas at full fire than the old tank. In homes from the 1950s through the 1980s, that often means upsizing part of the gas line. See gas line installation.
Sizing for Several Showers at Once
A tankless unit is sized by how much hot water flows at the same time. Two showers and a dishwasher on a January morning is the test. We size for that, not an average day.
Venting Through the Wall
Most gas tankless units vent out the side of the house instead of up the old chimney. We plan the vent location so it meets code and stays clear of windows, decks and walkways.

"Alex came out to provide a quote for a tankless water heater I wanted installed. He explained everything in so much detail, about the electric upgrade I would need, about how the heater will actually work 'in real life' (not just on paper). Then it turned out my electric couldn't support the tankless. [...]"

Tankless Water Heater Questions From Northbrook Homeowners
Often, for larger households. But older homes may need gas or venting work first.
For larger households that run out of hot water, it often is: continuous hot water, more floor space and a longer life with regular descaling. The install can cost more in an older home that needs a bigger gas line or new venting, so we show you exactly what your home needs before you decide.
Yes, if it's sized for winter. Cold incoming water is the hardest test.

Yes. Scale, ignition and error codes are the most common issues.
Yes. Common problems include scale buildup, ignition or flame sensor issues, error codes and venting problems. Regular descaling prevents many of them.
