With the intense focus on all things electric, the use of heat pumps in applications that were once only in the realm of direct combustion is becoming more prevalent. However, what are the limitations on heat pump heating: Comfortable supply air temperatures? No problem. High supply water temperatures for radiant heating? Sure. Water temperatures necessary for industrial processes? Let’s talk about that. This seminar provides information on where the limits are, what the issues are and where we are right now in state of the art heat pump heating. We will be getting high (temperature), so please indulge responsibly.
