Anybody make their own, like out of an automotive style radiator?
tried it,,wont work.The auto radiator worked exactly like it was supposed to,give up heat real fast.For a few minutes you have warm air then it cools off.also most car radiators dont hold enough water >I used one out of a ford ranger because it nearly fit my duct work perfectly.
A Rear heater out of an older school bus should work as they are basically are an owb you are just using a big engine to heat the water.
i've been using one with my homemade boiler with excellent results. its a large truck radiator.they are made to remove heat from water (coolant) and transfer it to the air and they do it well. getting ready to build secound one now. first one i used large heater fan and this one i'm going to try a cheapo box fan.
Personally I wouldn't use a scrapyard radiator unless it was next to new. It will create a weak point in your system and if it springs a leak your OWB will drain out to the level of the outlet and your pump will run dry until you find it.
