    We will need a little more info...
    Is the piping hooked up to the heater both inlet and outlet?
    Was the unit properly winterized to prevent freezing?

    Gushing out where? Perhaps someone omitted an O-ring on a coupling, or forgot to reinstall the drain plug?

    Do you have an exact model number?

    If its an H200/250/400 series, there are two plugs on the manifold that need to be replaced before you open up the plumbing.

    Okay identified the problem. Took off side panel. There are 4 copper(?) u-shaped pipes. One of them has burst during the winter and has a 3/4" tear in it. Now what to do?? Is this repairable or is it a goner? I can't figure out how to post a picture or I would.

    Probably looks like the pictures in this. opened-the-pool-today-and-found-a-leak-in-the-heater-t60821.html

    A 3/4" tear is too big to just blob up with solder. A new heat exchanger probably costs the same as a whole new heater.

    Re: opening pool for season--water gushing out of heater

    3/4" sounds pretty big. I did fix one like that a few years back. Told the owner "no guarantees". Still holding as far as I know.

    I would suggest, if you can get it out, to take it to a radiator repair shop and see what they say.

    Can you post a picture?
