Swinton's seminar focused on how CCHT gathered data from two gas combination systems, whose performances were compared to a condensing gas furnace and conventional water heater over a winter season. The study also tested the effectiveness of electronically commutated motors (ECMs) for furnace fans.
"We are used to looking at technologies in a lab setting, but by putting technologies in homes, we can see how equipment interacts with all of the elements in a home," said Swinton.
