Lists of Eligible Integrated Mechanical Systems (IMS) for ecoENERGY Retrofit – Homes

The following are Integrated Mechanical Systems (IMS) eligible for the ecoENERGY Retrofit – Homes grant since they have been tested to meet the “premium performance” target of the Canadian Standards Association’s CAN/CSA P.10-07 standard. The premium performance target requires that the system achieve a minimum Overall Thermal Performance Factor (OTPF) of 90 percent.

An integrated mechanical system (IMS) performs three functions: space heating, domestic hot water heating and heat recovery ventilation. An IMS saves energy by using a sophisticated control system to ensure that excess heat generated by one function is used by the other functions, thereby maximizing energy recovery.

Natural Resources Canada does not endorse the services of any contractor, nor any specific product, and accepts no liability in the selection of materials, products, contractors or performance of workmanship.
