Questions about this item

What comes with the DHC 10-2 Classic unit and what must I supply?

The unit itself is included; you must provide 1/2 in NPT fittings, a 40 A circuit at 240/208 V, and suitable indoor mounting hardware.

How do I decide between the 240 V and 208 V supply options?

The heater operates on either voltage; choose the one that matches your building’s electrical service — 240 V delivers the full 9 600 W, while 208 V yields lower output.

What does the 9 600 W rating mean for actual hot-water delivery?

At 240 V the heater can raise water to a maximum of 130 °F with a minimum activation flow of .8 gpm; actual temperature depends on inlet temperature and flow rate.
