Traditional heat pump systems may encounter lockout in severe conditions, but this is definitely not the case for the SLIM 24 line of heat pumps. SLIM 24 Heat Pumps are able to deliver 100% heating output at 5°F, ensuring uninterrupted warmth for moderate winters.
The SLIM 24 Hyper Heat condenser unit is capable of delivering 100% or more heating output down to -4°F (-20°C), also operating under superior heating performance down to -22°F (-30°C) outdoor temperatures.
