    Help ..................Need Sq Ft Rating.

    I have a customer which is looking for a rating and I cannot find anything on it. He claims to have called Dunham Bush and they did not have the ratings. Does anyone have the sq ft rating for a Dunham Bush V400H Steam fired unit heater.

    Maybe a dumb-@ss-umption but

    400 MBH at 2# steam pressure? So 1,666 SF? Nomenclature assumption only :)

    I checked my D-B catalog and there is a tab card saying "Unit Heaters Out of Stock!", so no telling.

    The cabinet unit heaters are listed by nominal CFM so while the 400 MBH seems huge, 400 CFM seems hardly worth it, so I would go on the 400 MBH assumption.

    I have it.

    At 1060 rpm it would be 96,000 Btuh

    At 840 rpm it would be 85,500 Btuh
    Retired and loving it.
