Hydronic heat from the engine.
I plan on chasing warm weather so not much cold climate time is in my future. If I get too cold while parked, I'll use electric space heaters just long enough to get packed up and hit the road for warmer weather. I know the need for defrost and likely warm air blowing up front is a real need. I removed the original 3 heaters in the back because they are too big and way too loud, and I don't plan on ever needing that much heat.
My idea is to run coolant from the original in and out at the back, but run through pex in the floor up to the front and tie into the original heat and defrost. I can shut off the coolant flow with the valves in the back during hot weather. If it's cool enough we need heat at the front, then it should be cool enough that we will enjoy the heat from the floor.
I scanned through 10 pages in this heating & cooling section and read everything I found on the subject. There are two threads in particular with a great deal of info in them, and I think I'm on the right track here.
Anybody have any advice or see any problems with going this route?
