Hot Water Recirculation Systems

Описание: There’s more to designing a domestic hot water (DHW) recirculation system than just adding another pipe and circulator. John Siegenthaler, P.E., a favorite guest speaker to the webinar series, will describe the objectives and benefits of recirculating DHW systems including simple single loop systems, and multi-branch systems. He will explain the concept of temperature-based flow control in recirculation systems, and thermal balancing. John will conclude by showing an example of how unique products such as the Caleffi ThermoSetter™ valve provide intelligent, safe, and energy efficient operation of multi-branch recirculation systems.

You'll learn:
→ What are the benefits of domestic hot water recirculation systems?
→ What can happen in domestic hot water systems that do not have recirculation provisions?
→ How should plumbing designers determine flow rates in a domestic hot water recirculation system?
→ What are the advantages of temperature-based control of recirculating domestic hot water systems?
→ How can a variable speed circulator be used in a domestic hot water recirculating system?

A seasoned industry leader and visionary, John shares his over 35 years’ experience in the understanding and proper application of water-based engineering principles and passion for teaching with our audience. He is a regular contributor to industry publications Plumbing and Mechanical, PM Engineer and HPAC magazines.
