Last month’s webinar briefly discussed the importance of low water temperatures when applying air-to-water or water-to-water heat pumps. The December 12 webinar picks up where last month’s webinar left off. We will discuss various heat emitter options, ranging from heated floors to radiant wall and ceiling panels, panel radiators, fan coils, and air handlers. It will also show how to evaluate existing cast-iron radiators for use in lower-temperature systems. The practical aspects of applying each type of heat emitter will be presented along with performance estimating methods.
