Why is the dhw tank heat exchanger volume and surface area smaller than typical indirect water heaters?
The heat exchanger is designed to optimize heat transfer for both heat pump and solar operation and takes into account Daikin inverter compressor technology allowing higher heat pump capacities at lower outdoor ambient conditions. The DHW tank heat exchanger volume is 1.8 gal/6.8 l and surface area is 15.6 ft2/1.45 m2.
