The Problem
The buildings existing conditions consisted of a marginally functional pneumatic and stand-alone mixture of control systems. Making the previous boilers inefficient, over sized, and offered no network connectivity or control. The existing three Teledyne Laars 600 MBH gas fired hot water boilers offered 70% thermal efficiency, while the existing 60-gallon atmospheric natural gas heater functioned roughly at 70% AFUE.
The Solution
Guardian Energy replaced two of the existing boilers with a new 95% efficient condensing boiler and 1/6 HP pump primary circulator to provide higher heating efficiency, lower pumping energy, the ability to control the boilers with the BAS, and lower standby losses due to the smaller, better-insulated boiler tanks.
Project Details
Guardian Energy provided Milton Town Hall with the design, engineering, and implementation of upgraded boilers and a domestic hot water heater. The upgraded boilers and hot water heater reduced energy costs by over $3,000 annually and qualified the customer for $8,000 in Commercial Gas Rebates.
