Yukon Big Jack water heating tubes

Does anyone heat their hot water with the water heating tubes on the B.J? Is it worth it.

I'm not a plumber, actually I hate plumbing, so I haven't done it yet. But I am going to set it up, planning on 2010, or if I can trade some of my wood to a plumber friend for him doing it, then I will in 2009.

I think to really do it right, you need to preheat from the furnace into a separate hot water tank, then your propane or electric hot water tank draws from that.

There are a few threads that talk about this very issue, just do some searching for hot water or yukon, or ...

The Hot Rods are a pre heater.They have the capacity to make 18 gallons per hour at an 80 degree rise.
They can be plumbed in a few different ways.Like Craig mentioned in his post there is a link to go look at them.
They sell for $208.
