Entry # 55
Winthrop / Williams Fuel Companies
Designer: W. Douglas Guerette
Customer: Maine
Installation Location: Heating System Upgrade
Brief overview of the project
Winthrop Fuel was approached by one of our customers looking to save fuel and upgrade their existing heating system.
We removed an old HB Smith boiler and installed an energy efficient System 2000 EK-1 boiler.
Design goal
Simplifying the installation by using the Caleffi Presscon Zone Valves.
Installation description
This is retrofit.
Challenges: We like the idea of Presscon press products because it allows for most jobs like this to be done in 1 day instead of 2. We also like the Caleffi Z55P's because the unions allow us to easily service the body of the valve in tight spaces like this job.
System performance
The combination of the Caleffi Z55P's and a new Grundfos Alpha ECM pump has improved the electrical efficiency greatly compared to the old system.
