The pilot house is heated with the diesel furnace, and a blower unit with five ducted outlets. 

​Three of those ducts go to the front windows, as heaters/defrosters. 

When we got to the boat, we found that the factory had hooked up both of the remaining ducts to the grill you see on the right. I wasn't sure that the unit could force all the air it puts out through that grill, plus I'd rather have more places where warm air can come out. 

We talked through the possibilities and decided that it would be possible to duct across the back of those drawers and add a grill as you can see this tech getting ready to do. 

The interesting part is that shortly before this area was taped off, the techs were having a heated discussion, pardon the pun. The first decision was to put the grill (and box for the duct behind it) at the floor level. When the guy that built this cabinetry arrived to cut the hole, he flat out refused to cut it there. Because then it would be at a different height than the one on the right. 

The other techs remarked that the ducting would require a lot more work in order to accommodate his location. (I'm getting the translation from Chinese, right?) He continued to refuse and then the other techs realized they had lost and had to figure out how to do the ducting, which they did, and he proceeded to cut out the hole.

At left you can see the completed new duct. The blower unit I mentioned is shown inside this cabinet on the right. The added a false floor there to protect the duct when someone has to climb in there to work on electronics.  (It's much larger than it appears in this image.)

I'm so thankful the HYG techs care so much about the boats they build.
