VOLUME 8 / ISSUE 1 / JUNE 2021 A building management system (BMS) allows a building manager to monitor and control all the systems in their building or campus from a single interface and is most often applied in larger buildings with HVAC, mechanical, and electrical systems similar to the Domestic Condensate packages we provide.
VOLUME 8 / ISSUE 1 / JUNE 2021 Float and thermostatic (F&T) traps have an important role in distributing steam throughout a system. They allow air to pass through into a return line allowing steam to flow properly throughout the system. Air in a steam line will prevent steam from entering the line causing increased
Volume 7/ Issue 2/ April 2020 Back in the days of coal and wood fired boilers, heating contractors used vacuum air vents to help them get the maximum efficiency out of their steam heating systems. They called these old systems “Vapor/Vacuum,” and the principle that made them work was a simple one: At very low
Volume 7/ Issue 2/ April 2020 When we think of our Condensate Return Units the first one that comes to mind is our standard CC unit. As with any packaged unit, there are times when field conditions create a non-standard installation and operation environment. As a result, questions arise on what can be done. One
Volume 7/ Issue 1/ January 2020 This article is intended to simplify the selection of components for a steam heating system. The majority of steam boilers used in heating systems are rated on the BTU heat output. Selections are based on modern steam boilers, many older steam boilers had sufficient water storage capacity to fill
Volume 6/ Issue 3/ October 2019 When a steam trap failed open, and allows live steam to pass by, it is easy, and convenient to ignore symptoms or place on our never-ending list of “things to do.” After all, what harm is it besides wasting little energy that cost a few bucks? The boiler is
Volume 6/ Issue 3/ October 2019 The well-known Domestic Pumps from Xylem can handle up to 212ºF of boiling condensate, without cavitating, without vapor locking and in many cases even without elevating the tank. Units will do their job and transfer the condensate back to the boiler room, or to the boiler itself. The condensate
Volume 6/ Issue 2/ August 2019 Float switches are very important part of Domestic Pump units. They perform variety of functions for both condensate return and boiler feed units. The switches are operated by the movement of the water level in the tank. They include electrical and mechanical parts. The electrical part is in a
Volume 6/ Issue 2/ August 2019 There are both legal, and practical considerations that create the need to install mechanical or electronic low water cut-off (LWCO) control on a residential hot water boiler. From the legal side, jurisdictions have adopted codes which state when an LWCO must be installed, while the practical side is based
Volume 6/ Issue 1/ April 2019 With steam heating systems, you can count on one thing: They will always need feed water. How much water they need depends a lot on the system’s age and condition, but the feeding process never ends. Where does the water go? It leaves the system by evaporation, through leaky
