background

New Standard in Performance

The 5 series 504W11 can reduce water heating costs by as much as 60% per year. Ordinary boilers and water heaters operate at a fraction of the efficiency of the 5 Series. With built-in OptiHeat vapor injection technology, this unit incorporates an additional heat exchanger that moves excess heat and reinjects it into the system. This technology provides higher exiting water temperatures and better compressor operating conditions. Smaller loads are required and result in the ultimate in efficiency.
