The Basics

How a Tankless Water Heater Works

A tankless heater only heats water when a hot tap opens. Water passes through a heat exchanger, a gas burner or electric element heats it instantly, and it flows to the fixture. Because there's no tank to empty, the hot water doesn't run out mid-shower. The catch is sizing: the unit has to handle every hot tap you run at once, and it needs enough gas, the right venting or enough electrical capacity to do it.

Local Knowledge

Tankless in Tinley Park Homes

Tankless can be a good fit for Tinley Park families who keep running out of hot water. A few things decide whether it fits your house.

Several Showers on a School Morning

We size the unit for the busiest 20 minutes of your day, not the average hour.

Gas Line Size

A gas tankless unit can need much more gas than the old tank. Some homes need a larger line from the meter. See gas line installation.

Cold Winter Water

With several nights a year at or below zero, incoming water is very cold in January. We size for that month so the unit keeps up.

"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. [...]"
