24 VDC appliances?
Rick,
If you use a water cooled muffler as a heat exchanger to heat your fresh water, at some point your freshwater tank will be hot enough. You now must have a mechanism to dump the absorbed exhaust heat or damage will occur somewhere in the system. Most colorifiers use the engine's cooling water circulating through an imersed exchange coil in the hot water tank. In that way, the engine's cooling system itself is the energy dump. If the exhaust system is used, another mechanism must be found. Steve "Rick" wrote in message nk.net...

So you need auxillary cooling, when your heat demand is low. I guess there is no free lunch. ??? Are you suggesting there are systems out there that use the domestic hot water system as a heat sink for the engine cooling requirements? Or that someone would install a heat exchanger that is rated at a lower temperature than the operating temperature of the engine cooling circuit? Something is missing here. Rick |
