Tankless Water Heater Installation Chicago
Endless hot water, lower energy bills. D's Air & Heating, Inc. installs and services tankless water heaters throughout Chicago.
Why Chicago Homeowners Are Going Tankless
Traditional tank water heaters waste energy keeping 40–80 gallons hot around the clock. A tankless unit heats water only when you need it — cutting energy use by up to 34% and delivering unlimited hot water on demand. D's Air & Heating, Inc. has installed tankless systems throughout Chicago since 2009.

Water Heater Installation in Chicago — What Homeowners Should Know
Tank vs. Tankless Water Heaters
Traditional tank water heaters store 40–80 gallons of hot water, ready on demand. They are less expensive upfront but continuously heat water even when not in use (standby loss). Tankless (on-demand) water heaters heat water only when needed, eliminating standby loss and providing unlimited hot water. Tankless units cost more upfront but typically last 20+ years vs. 10–12 years for tank units.
Sizing Your Water Heater
Tank water heaters are sized by first-hour rating (FHR) — how many gallons they can deliver in the first hour of use. A family of four typically needs 60–80 gallons FHR. Tankless units are sized by flow rate (GPM) and temperature rise. Undersizing causes cold water complaints; oversizing wastes energy. D's Air sizes every water heater to your household's actual demand.
Venting and Gas Requirements
Gas water heaters require proper venting to exhaust combustion gases. Atmospheric units use a draft hood and natural draft flue. Power-vent units use a blower to exhaust horizontally through PVC pipe. Direct-vent units draw combustion air from outside. Each type has specific clearance and termination requirements. D's Air verifies venting compliance on every installation.
Water Quality and Anode Rods
Chicago's water supply is moderately hard. Mineral buildup (scale) reduces water heater efficiency and shortens tank life. The sacrificial anode rod protects the tank from corrosion — it should be inspected every 3–5 years and replaced when depleted. D's Air checks anode rod condition on every water heater service call.
