Endless hot water and a smaller footprint. King's plumbers install, service and repair tankless water heaters across Chicagoland and Northwest Indiana.
A tankless, or demand-type, water heater doesn't store water. It heats water as it flows through the unit, so your home gets hot water on demand without paying to keep a tank hot all day.
That makes tankless a strong fit for busy households that need hot water at the same time every morning. Our plumbers repair and maintain the tankless heater you already have, and install new units.

Lake Michigan water is moderately hard, around 7–9 grains per gallon. When it flash-heats inside a tankless unit, minerals bake onto the heat exchanger.
Left alone, that scale drives up gas use and can eventually crack the exchanger, which usually means a full replacement. An annual flush prevents it. Between visits, rinse the air intake filter every six months and check the inlet screen and condensate line.
Tankless costs more to install than a tank. Here's what you get for it.
Heated on demand, so the last shower is as hot as the first.
24–34% more efficient than a tank for homes using 41 gallons a day or less, per the U.S. Department of Energy.
20+ years with proper annual maintenance, versus 10–15 for a tank.
Wall-mounted units free up room in the basement or utility closet.
It mostly comes down to how long you'll stay and how your household uses hot water.
If you're staying 10+ years, the lower energy use and a skipped tank replacement usually make tankless worth it. Planning to sell within five years? A standard tank is often the better buy. We'd be glad to look at your home and tell you honestly which fits.
