    plumbing_Page_3.png I'm getting ready to add a plate heat exchanger between my Wood Boiler 40K BTU and my ancient oil boiler.

    Currently there is hot water storage and I am concerned about 2 specs.

    1) how large of an exchanger should I purchase?
    2) What are the side effects of the pressure drop across the heat exchanger?

    Thanks for the advice

    What boiler did you have that will need a plate heat exchanger?

    I've got a tarm solo 55mb 138,000 btu. I'm looking for a simple storage solution that will get me just a little bit ahead of the curve.

    This morning I'm revisiting CWCoils again. My tank is only good for about 170,00 BTU.
    But thats at least a solid day of heat that I can add to the house.

    I see hot supply water going from the wood side to the oil side, and cold return water going from the wood side to the oil side.

    I don't think that will work.

    But maybe I'm not seeing things right, it has me kind of confused.

    Two automags?

    I think the intent is charging pump and a drawing pump.
    Is the presence of a pump enough?
