I'm designing a system that would utilize a Webasto diesel fired boiler to provide heat, and an Aquahot or Toyotomi Oil Miser to heat drinking/shower water... I would like to be able to heat the water with some kind of heat exchanger right off the radiator. This would allow me to have hot water while the coach is mobile without wasting diesel by firing up the Aquahot. It would also help the coach run a bit cooler. Now for the question:
Where can I get one? |

I saw a small one in a van conversion,seemed like it heated about 10 gallons..it was a water tank,with coiled copper radiator water runing through it..... |

one idea..get a air tank,(harber frieght)get a roll of 3/8 copper,wind it around & around the outside ,insulate it tee off heater hose,go to one end of copper,tee off other heater hose,to other end of copper...it'd be a lot better if you could find a stainless tank... |

An RV or marine water heater with an engine heat exchanger may suit your needs for heating the water while driving, but if you are trying to heat the water while running only the Webasto you should be aware that it would take a few hours since the heat pipe off the cooling system only attaches to the outside of the water heater for a few inches.

I believe the aqua-hot already has that capability. It is piped thru the bus water system thus providing hot water if you've been driving the bus.

Ps. sorry Ian, I forgot again.

I been thinking..you could take your present water heater,remove the outer shell & insulation,wrap the roll of copper tubeing,re-install the insulation & outer shell.I bet that would work. |

The biggest thing im concerned with is contamination. Ethylene glycol is some nasty stuff, it totally dehydrates tissue it comes in contact with. The copper coil idea is great, it reminds me of what's called a "wort chiller," only in reverse (I brew beer, it's basically a copper winding you run cold water through to rapidly chill the beginnings of beer). Hey, wait a sec.. a stainless steel keg would work great. That would probably drop the pressure, (and hence, the boiling point) of the coolant, though. And if it somehow got contaminated, it would wreak havoc on anyone who drank it. If the Aqua hot already has the capability, that would be a huge bonus. What about the Toyotomi? |
