I hooked this Modine up so the return goes thru it before going back out to the boiler. The fan is just hooked up to plug in when I want to get heat in the garage/shop. The water is about 155. It is not really throwing as much heat as I remember from years ago in the basement.
Question is: can I put a rheostat on this kind of motor without doing any harm to it? I feel like the fan is blowing so hard it is not transferring heat, is that possible?
