The following are Integrated Mechanical Systems (IMS) that have been tested by a third party accredited by the Standards Council of Canada according to CSA P.10-07 “Performance of Integrated Mechanical Systems for Residential Heating and Ventilation” and meet or exceed the Standard's premium performance requirements. The premium performance target requires that the system achieve a minimum Overall Thermal Performance Factor (OTPF) of 85 percent.
An 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.
