I have an older style aqauhot with the copper coils circling the exterior of th boiler tank. When I add antifreeze should it be engine antifreeze or boiler antifreeze? The aqauhot manual says boiler, but several post here say engine.
Which leads to a second question. Can anyone explain the engine preheat plumbing loop to me? Is it tied into the engine cooling system etc.
