“The system has worked with minimal problems, and the performance has exceeded our expectations. The units run continuously without much need for supervision, and have almost eliminated our boiler usage.” – David Kyle, Facilities Manager

Project Overview

The Connection, Inc. is a transitional living environment for people in recovery in New Haven, Connecticut. The five-floor building consists of four floors with housing and a bottom floor with offices and clinics. Two Yanmar CP10WN units were installed to provide electricity and hot water to the housing units with the use of the grid and existing boilers as backup.

Reason for Choosing Yanmar

The customer’s main reason for selecting the Yanmar Combined Heat and Power systems was their ability to reduce operating costs. Natural gas is a much more cost-effective alternative than grid electricity; it is also a much more efficient method for providing heat and power to the building, while also increasing the resiliency of the building’s existing heating system.

In addition to the economic savings and improved efficiencies, the customer was also sold on YANMAR’s reputation for quality engines and a product with a long maintenance interval of 10,000 hours, which equates to less maintenance costs and downtime.


  • The CP10WN system has resulted in an average monthly savings of almost $800 by switching to natural gas-driven electric and heat production.
  • The units operate for more than 1,100 hours per month on average.
