Improving on what works Do you drive the same way to work every day? Most likely you do. Things we repeat every day become easy and do not require any impossible effort. When designing plumbing and HVAC systems, we have the same tendency. But just because something works, doesn’t necessarily mean it couldn’t get better or smarter.
PURPOSE During the last few years, there have been more changes to plumbing, HVAC products and solutions than we have seen in decades. Products are not only controllable by means of electronics; the Internet also provides a new layer of possibilities. One example is pumps that now provide a variety of other features besides the original duty of circulating the flow in the systems they serve. In this article, we talk about a specific application – hot water recirculation (HWR) – and demonstrate how new technology can influence the way we do things.
