The MRCOOL UHK15 Universal Series 15 kW Heat Kit is an electric supplemental heating accessory designed for compatible MRCOOL Universal Series air handlers using R-454B refrigerant systems. It works by converting electrical energy into heat, which is distributed through the air handler and ductwork to provide additional warmth when needed. Equipped with a circuit breaker, the kit supports safe and convenient operation while integrating with the air handler’s electrical system. It is ideal for residential HVAC applications requiring auxiliary or backup heat, helping improve cold-weather comfort, system flexibility, and dependable heating performance during demanding conditions.
