The Basics

How a Tankless Heater Works

A tankless heater fires only when a hot tap opens. Water flows through a heat exchanger and comes out hot for as long as you need it. Each unit has a flow limit, so we size it for the most hot water your home uses at once.

Local Knowledge

Is Tankless Right for Your Evanston Home?

A few local factors decide it.

Scale From Local Water

At about 7.8 grains per gallon, a yearly descaling keeps it running well.

Venting

Tankless units vent through a wall, not the chimney.

Gas Line Size

Older gas piping may need to be upsized.

Condo Rules

Check with your association about exterior vents.

Tankless Heaters and Evanston's Water

A tankless heater has a narrow heat exchanger, and minerals in hard water can build up inside it. With Evanston's hard water, that means descaling about once a year to keep the unit efficient and protect the warranty. Many homeowners pair a tankless heater with a water softener or a scale-reduction filter. We'll explain the options and set you up with a maintenance schedule when we install it.

Pricing

What Affects the Price of a Tankless Install

Gas line size and venting are the two big variables. Older homes often need a larger gas line to the heater and a new vent through an outside wall. Removing the old tank and adding isolation valves for descaling are part of the job. We check everything first and quote one flat price.

"Mr. Welham Mendoza, from Blanton Plumbing, installed a water heater in our home on April 3, 2026. Mr. Mendoza was on time, friendly, professional, and clear in explaining how our system worked. He had to make a second trip to secure a water heater that fit. He was extremely knowledgeable and efficient in the installation."

"Edgar's the man. Not only did he install my water heater, but asked to test the quality of the water to see if that could've lead to the damage and the leak of my last water heater. My water was at a 7 on the hardness scale, and it's supposed to be at 2 or 3. So he reccomends a new water softener, and im thankful that he did. [...]"
