EVO Copper Finned Tube
Our EVO Copper Finned Tube systems enhance heat transfer efficiency in commercial water heating applications. Designed for durability in high-demand environments, these components reduce energy consumption while maintaining consistent performance. Their corrosion-resistant construction ensures long-term reliability in facilities with challenging water conditions.
Factory Assembled Systems
We deliver fully pre-plumbed and factory-tested heating systems that minimize on-site installation time and costs. Each unit undergoes rigorous quality checks before shipment, ensuring seamless integration with existing infrastructure while meeting strict safety and efficiency standards for commercial operations.
Storage Tanks
Our storage tanks provide reliable hot water reserves for commercial facilities requiring consistent temperature control. Engineered for high-capacity use, these tanks maintain thermal efficiency while reducing standby heat loss through advanced insulation technology.
System Components
We supply precision-engineered components for hydronic boiler systems, including valves, pumps, and control modules. These parts ensure optimal system performance and are designed for easy maintenance, reducing downtime in critical commercial operations.
Companion Eliminator
This solution addresses poor water quality challenges by removing contaminants that cause scaling and corrosion in heating systems. Its integration extends equipment lifespan while maintaining peak efficiency in facilities with hard water or high mineral content.

Dec 18, 2018 Report
I would give Hamilton Engineering no stars as to quality, service, of their products. I would recommend to all commercial users to STAY AWAY from them. We purchased (2) EVO boilers in 9/16 and they have been nothing but trouble. From questionable support on install (they only had 2 people in tech support and it takes them forever to get back to you) to a product that should be ranked one on the worse.

Our 30 year old Hydrotherm boilers were of better quality than these units. Even thrying to get help to hook them up to a building automation system is a pain and was string out. Their distributor for Northern Indiana, is just as bad.

Nov 29, 2017 Report
I have an EVO micro 179 boiler installed in my house. It is 8 years old and I have spent thousands trying to keep it going. I have serviced annually, and have still replaced several fan units as they gather moisture and the bearings fail. I have received a horrible lack of service from the Canadian parts supplier. All in all I would recommend not touching this company.
