ectric tankless water heaters are still not very popular in many Illinois homes — but we’re starting to see them more often during inspections.
These systems are very different from traditional tank-style heaters. They require proper electrical capacity, correct wire sizing, appropriate breaker configuration, and manufacturer-compliant installation to operate safely and efficiently.
As inspectors, it’s important to understand how these systems function, what to look for, and where installation defects can create performance or safety concerns.
The industry is evolving — and so should our knowledge.
Staying educated means better inspections and better protection for our clients.
