    General Description Daikin TGZ water heaters are scroll compressor refrigeration units that recover heat from warm fluid streams in the evaporator and deliver hot water, at a useful temperature, from the condenser to a heating load. They are designed for indoor installations only and are completely assembled, wired, charged and tested.
