can you get flatplate hotwater exchanger for gas engine. it's now listed in ford/chevy options-no mention of diesel needed

Its just hot water from the cooling system, they can be used on any liquid cooled engines gas or diesel.

With my system I have a flateplate that works off the engine cooling system but also have a stand alone heater made by Espar that also heats the engine coolant (and flatplate) which gives me hot water while the engine is cold. There are a couple companies that offer gasoline versions.

Dave,
I'm considering getting that espar unit. How long does it take to heat the water in the morning?

Don, it all depends how the hydronic cycles to start. (I have the diesel version) With mine at least, the speed to start varies. I don't know why but at times it will take about 2-4 min and the water is hot. Other times the unit will cycle through a code and might take about 5-7 min to bring it on full. I also suggest having the flate plate pump added so you can warm the engine block faster or use the engine as the heater for the flat plate. It (the pump) doesn't have to be used when running the Hydronic unit by itself but hot water from the engine will give enough for a shower after a hot motor is shut off when using the pump by itself. Kind of nice to have a backup.

Feel free to post more questions or using the sites search feature, type Hydronic and it will take you to more posts about the Espar, and if you use my name as author it should be more specific to my posts. Good luck
