Common Water Heater Problems

Why tankless water heaters break down in Chicago

Tankless water heater installation | sensational heating & air

While tankless systems are highly reliable, local water conditions and aging setups can cause internal components to fail when you least expect it.

Control Board Malfunction

A burnt control board cuts off all communication inside your heater. Power surges from summer storms can fry these circuits, leaving you without hot water until it’s fixed.

Ignition Sequence Issue

Dirty burners or faulty igniters stop the gas from lighting safely. When your system misfires, it shuts down immediately to prevent raw gas from building up in your basement.

Scale Buildup Restriction

Hard water coats the internal copper heat exchanger with heavy lime crust. This scale restriction forces the unit to work twice as hard to heat water, spiking your energy bills.

Flush Your System

Internal Leaks / Corrosion

Neglecting annual maintenance causes condensation or loose pipe fittings to corrode the inner copper lines. Small internal leaks slowly rot the bottom casing and destroy the lower electronics.

Choosing the right tankless water heater for your home

gas or electric

Match Your Fuel to Your Home Infrastructure

Most Chicago bungalows and two-flats run on natural gas, making a gas setup the easiest swap. If your home lacks gas lines or proper venting paths, an electric tankless setup can provide point-of-use heat for smaller spaces like a garden unit.

Compact Heating Built For Tight Spaces

An electric tankless system requires zero venting and tucks neatly into tight crawlspaces or closets. These units require heavy electrical currents, so we audit your ComEd panel first to see if you need an amp upgrade before the plumbing begins.

Stop Paying to Heat Water You Aren’t Using

Traditional water heaters keep dozens of gallons of hot water in a tank, constantly burning energy to keep it warm. Upgrading to a new tankless system only fires up when you open a tap, giving you massive energy savings over time.
