I noted that my HydroHot burner bearings were very easily found skateboard wheel bearings. Most all bearings aren't proprietary. Most of the time one can find the part number stamped on the bearing shield to get it much less expensive on ebay / amazon / alibaba.
I too had to replace the coolant level sensor. This could / should be an electrical sensor, not a mechanical one like it currently is for longer life and lower cost. With research, I bet you could find an out of the box alternative if you measured the hole / thread dimensions. I just didn't have time for the project so just overpaid the price to get a new plastic OE one.
yes the radiator cap sounds like something that should have been repurposed from auto, but mine is much larger than any auto rad cap I have seen. Not sure why it was designed by HydroHot with that proprietary design, but it is what it is.
Decisions like that are why I am looking at an AquaHot ad selling the unit for a "discounted" $6290.90 price tag. Nuts for what it really is.
