The Basics

How a Tankless Water Heater Works

A tankless heater only heats water when you turn on a tap. Cold 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 all day, so you don't pay to reheat water you're not using, and you don't run out. The tradeoff is flow: each unit can only heat so many gallons per minute, so it has to be sized to how many fixtures you run at once.

Is Tankless Right for Your Arlington Heights Home?

Tankless is one of the most searched water heater upgrades in Arlington Heights. Here's what decides whether it works in your house.

Gas Line Size

Tankless units need a lot of gas when they fire. Many homes built in the 1950s through the 1980s have a gas line sized for a furnace and a 40-gallon tank. We check it and tell you if it needs upsizing.

Venting Out of the Old Chimney

Tankless heaters vent through the wall or roof with their own pipe, not the old masonry chimney. That frees the chimney but means planning a new vent path.

Winter Water Temperature

Incoming water is coldest in January. We size the unit so it still delivers enough hot water on the coldest mornings.

"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. [...]"

Got Questions?

Tankless Questions From Arlington Heights Homeowners

Yes. Regular descaling keeps the heat exchanger clean.

Yes. Minerals in the water build up in the heat exchanger over time. Descaling on a regular schedule keeps it efficient and protects the warranty. We install service valves to make that easy.

Often, if it's sized for the number of fixtures you run at once.

Often, yes. A properly sized unit handles a couple of showers and a dishwasher at once. Very large homes or big soaking tubs may need a larger unit or two.

Often a flow or scale issue, or water use below the activation rate.

Short bursts of cold water can come from scale in the heat exchanger, a dirty inlet filter or a tap opened so little that the unit doesn't fire. A service visit usually sorts it out.

If you want endless hot water and plan to stay, it can be.

It can be, especially if you run out of hot water now, plan to stay in the home and want the basement floor space back. If your gas line and venting need major work, a high-efficiency tank may be the better value. We'll lay out both.

It depends on the unit, gas line and venting. You get a flat price first.

It depends on the unit size, whether the gas line needs upsizing and the venting path. We give you a flat-rate price before any work begins.
