College of Product Knowledge: Introduction To Water Heaters
This is an updated version of the product training course introduced by Supply House Times in 1979, authored by Don Arnold.
The total picture of water heater models offered today is rather large and complex. Before getting into all the variations, it is important to understand the basics, which is what this segment is all about. We won't be getting into the anatomy of components and features this time, but rather, establish the primary points of distinction when it comes to specifying products in this category.
