posted on Monday, March 15, 2021 in CHP Case Studies

“Since installing our first YANMAR CHP System in April 2018, the system has operated with no issues. We are very happy with the savings the CHP system provides, and are interested to see how it will perform over time.” – Property Owner.

Project Overview

This client is a 12-story multi-family apartment building owned by Drewlo and located in London, Ontario. The building consists of multiple one and two-bedroom apartments, as well as a saltwater pool, hot tub, and sauna. DBS installed a 35 kW YANMAR combined heat and power (CHP) system on the building’s roof to provide 24/7 power and hot water to the facility.

Reason for Choosing YANMAR

With a 62 dB(A) rating from three feet away and overall efficiency of 88%, YANMAR’s CP35D1-TNUG system was able to meet Ontario’s strict emission and noise requirements.

The system is able to generate 204,040 BTUs of heat per hour; this heat is then used for domestic hot water and building heating with the 35 kW of power used to offset the grid. By producing both heat and power onsite using clean, efficient natural gas, the building is able to reduce its operating costs.

In addition to efficiency and reduced costs, the YANMAR system also provides high reliability with a 7,500-hour maintenance interval and 24/7 remote monitoring capabilities for faster unit servicing by their local dealer, DBS (www.dbspowerenergy.com).

Results

Overall, the CP35D1’s utilization is high, averaging 93% over seven months.
The CP35D1 has resulted in average monthly savings of$2,400 by switching to natural gas-driven electric and heat production.
The unit has provided consistently reliable operation with an average of 668 operation hours per month.
