The Basics

How Tankless Water Heaters Work

A tankless unit heats water on demand. When you open a hot tap, water flows through a heat exchanger and comes out hot for as long as the tap stays open. There's no tank to keep warm overnight, so it uses less energy when the house is quiet. Its limit is flow, so it's sized for the most hot water you use at once.

Local Knowledge

Is Tankless Right for Your Elmhurst Home?

Many Elmhurst homes can make the switch. A few things come first.

Descaling Is Non-Negotiable

With about 8 grains of hardness, a tankless unit needs yearly descaling or a softener.

Gas Line Size

Postwar gas lines often need to be upsized.

New Venting

Tankless units can't share the old chimney.

Space in Older Basements

A wall unit frees up the floor.

Tankless Heaters and Elmhurst's Water

Elmhurst's water runs about 8 grains per gallon. In a tankless heater, minerals collect in the narrow heat exchanger and slowly reduce efficiency. Most units will show an error code or lose hot water output when scale builds up. Yearly descaling prevents that. Adding a softener can stretch the interval and protect other fixtures too.

Pricing

What Affects the Price of a Tankless Install

The unit is only part of it. Most of the variation comes from the gas line, which may need to be larger, and the venting, which has to reach an outside wall. Removing the old tank and adding isolation valves for future descaling are part of the job too. We check all of it first and give you one flat price.
