The benefit of terminal reheat is versatile and may be installed or taken out to support variations in zones, which provides much better control of the thermal disorders in multiple zones. Nevertheless, the design of terminal reheat just isn't Vitality-effective system due to the fact a big level of really cooling air just isn't regularly necessary in zones, which may be considered as squander Electricity. Thus, Vitality codes and requirements regulate the use of reheat systems.

Other systems employed for air flow are air circulation devices which include desk or paddle supporters to further improve thermal consolation with the House by allowing the heat to be transferred by typical manner [5, six].
