Squamish General Hospital - Condensing Boiler and Controls Upgrade

    New Boiler Distribution Pump VFD's now run 15 HP pumps as low as 1 HP at low loads.

Client: VCHA
Venue: Squamish General Hospital
Year: 2013
Type: Health Care

Boiler Upgrade

This project involved the installation of a new 1750 MBH condensing boiler and auxiliary systems, to achieve optimized and efficient hot water heating. The new condensing boiler serves as a lead boiler and the existing large Bryan boilers are only enabled on failure of the new boiler or if the outside temperature is too cold for the boiler to heat the hospital. Over the first season of operation it was found that the new boiler was able to serve the heating alone, even with the new Pharmacy building addition which increased the load by 1500 MBH.

Pumping power for the heating loop was reduced from 14 kW down to as low as 1 kW with the new variable speed pump and heating loop modifications.

Control System Upgrade

The project includes upgrade of the building controls required for the boiler upgrade, existing heating system circulation pumps, and hot water heating plant. For future optimization purposes, the BAS system was upgraded to the latest BACnet technology from Siemens Apogee.
