Quality Differences Between Retail and Professional Grade Water Heaters
When you’re looking to replace your water heater, it’s key to know the difference between retail and professional-grade units. Not all water heaters are the same. The quality differences go beyond just the price.

Ventilation Requirements
Proper ventilation is key for tankless water heaters. Unlike traditional units, these systems need direct-vent installation. This means precise piping to the exterior.

Given the complexity, professional installation is not just recommended. It’s essential for safe and efficient operation.
