How Low Water Cut-Offs Improve Boiler Room Safety
Steam boilers have two main safety devices: primary (LWCO) and auxiliary low water cut-off (ALWCO) switches. Water in the boiler should always remain at the normal operating water level (NWL). The low water cut-off switches are set below the NWL. The exact position below NWL varies, depending on boiler construction, but is set such that…
Stop Wasting Money, Reduce Boiler Cycling
Does your boiler cycle too often? What is too often? Is cycling too often a problem? What issues can this cause? MOST IMPORTANTLY, how do we correct this? What is cycling? First off, for on-off boilers, the natural state is to cycle, from off-to-on-to-off-to-on and so on, to attempt to satisfy a load. Easy enough,…
Payback and LCCA – DON’T BE MISLED
Often, in our industry, we are requested to complete a Life Cycle Cost Analysis sheet or provide a payback estimate for new boiler-room equipment or efficiency boosting upgrades. We pride ourselves on being as accurate as possible with these estimates – one of our Core Values is Integrity Over Profit. You’re using these estimates to…
