I have a proheat and know how to install it, after that, I am lost. I know there is a way to preheat engine, water heat, coach heat, maybe a couple of zones, and switch back and forth as required. I don't know where to start. I guess I just started...
Thanks guys |

Bruce,
The best way to preheat the engine and get heat from the engine is with a heat exchanger between seperate coolant loops, one for the engine and a seperate one for the 'furnace'. In addition to preheat the engine you'll need a small electric pump to circulate the engine's coolant. Coach heat can be by 'radient' finned tubing or just exposed tubing and or small fan forced heat exchangers. Domestic water heat is usually with a colant heat exchanger equiped water tank, these are available with 120 volt heaters in 6,11 & 20 gallon sizes from Seward and others. You'll need an aquastat to sense the domestic water temperature and it'll become a zone. Each zone will need a thermostat. The zones are connected to the heater through or logic usually done with simple diodes. Send me an email and we'll exchange phone numbers & discuss further.
Regards

Look at the Aqua hot web site. They have manuals on their system that show the pumps and heat exchanger hook up. They use a Webasto for their water heater but I think all the other stuff should apply to your system.
Good luck and all the stuff you need can add up to $$$. |

Bruce,
I'm at that same stage in my installation. I've drawn a layout of what I intend to do. I can email a 'pdf' of it and then you can see what my 'starting point' looks like. Basically, I'm tying the Webasto into the engine cooling circuit and using some 'full port' ball valves to control where it all goes. I'm taking advantage of the 24v circulating pump ( that was there and will be again soon ) to assist moving the coolant in the loop. By doing it this way, I don't have to have an expansion tank ( it uses the bus tank ), or a heat exchanger, or a coolant filter or conditioner ( added ). It uses 4 ball valves to get 3 different modes - Preheat - Webasto heat only - Webasto & Engine heat. Let me know if you want to look at the diagram. Phil in Az. |

Hi Phil,
I am installing Hydronic heat also. Could I see a copy of the .pdf diagram that you have drawn up please? Your idea sounds simpler than what I have looked at. I'm still trying to get ideas for the design.
Thanks,
Andrew.

I asked a long time ago for something like that on the board. Could I get a copy of that plan? |
