    DRAVO COUNTERFLO QUESTION

    Hello,

    We had water pipe burst over our Dravo Counterflo Furnace, causing it to fail. We can't figure out what is wrong, can anyone advise what problems could result from water damage to a Dravo Counterflo unit? Will attach photo. Any help would be much appreciated.

    Thanks,

    Thanks,
    Looks like age might have been a factor.

    Since it was working before pipe burst, what else could it be?

    Some of the old Honeywell modulating motors had some sort of fluid in them that would burn if it got wet.

    Dravo Counterflow

    The pipe that broke was spewing water over it for over 1/2 hour. It was soaked. I've been searching on internet but it seems the Dravo was discontinued and parts are impossible to come by.

    Time for a new / newer unit , the blower fan assemblies , they look a bit distorted , is there even a belt on the blower motor ( bottom RH side of photo ).

    Looks more like a unit that has not run in a very long time.

    Yes again...

    Unfortunately, electricity and water do not play together at all. Replacing parts will be a waste of time because when electricity, metals and water are involved you get electrolysis (one metal depositing at the atomic level to another metal) just like chrome plating. Flood/water damaged electrical/electronic items are 99.997% of the time write-offs...

    Sorry to give you the bad news, only very few recover electrical devices from a water disaster like you described. Please find a good contractor and have your heating appliance replaced, but check credentials/references first...

    I am personally not familiar with counterflow type furnaces, so I'd have to say that you should check around and find a certified outfit that knows about these things. Way up here, never have come across one...

    Dravo was bought out by Hastings Hvac, inc. in Hastings, Nebraska . If you need parts for that unit get your Model number and Serial number from the heaters spec tag. Then call Hastings Hvac service dept. at 1-800-228-4243 to get any up grades or parts needed .The heaters are custom built to spec and the serial number is important since it will lead them to file number. They keep all file for 1950's on with all the original parts that were added to heater when it was made.
    hope this helps you
