Mitsubishi Electric, Markham, Ont, announces its new intelli-HEAT dual fuel system, which consists of two units — an exterior heat pump, which replaces an existing air conditioning condenser, and an interior unit that is installed on the existing furnace.
It has the ability to determine the best sources of heat (gas or electric). Variable speed technology and smart controls reduce fossil fuel usage and greenhouse gas emissions. Able to operate with ambient temperatures as low as -13 F, its heating source averages 90 per cent electric, 10 per cent gas backup, and 100 per cent electric cooling source.
