Using an indirect tank as a heat exchanger?

    I am about to install an indoor wood gasification boiler and I found a good deal locally on an HTP indirect Stainless Steel Heat Exchanger for Pool/Spa Heating. I will not be using this for a pool but as a heat exchanger right off of the boiler.
    Here is a link to this product.

    This indirect tank is rated at 200,000 btu output which is more than I need but as I understand it the more output the better. Just wondering if a product like this can be used in place of a flat plate heat exchanger and if there is any advantage or disadvantage to doing so.

    Look around and see if you can find how their 200K BTU rating is achieved. It might require steady 180F or even 200F supply temps and relatively cold water from the pool (or whatever) to get that rate of heat exchange. Typical wood boiler supply temps and normal heating water return temps may derate that 200K under most conditions in a typical heating system.

    It may be a good deal but don't count on that rating until you find out how it was achieved.
