have any of you installed this type of heater? I was wondering what the best location is. In looking at the cooling/heating sys., it would seem that if I plumbed it into the heater line branch off the water pump, and then back in where the heater line returns to the head, I would get full ciculation through the block without restriction from the thermostat. Does that seem right?
