ergomax buffer tank install

no reason to use a buffer once you are over 15-20 minutes of firing rates I would think, so size the buffer to around that and valve it off-line for larger loads.

buffers help a lot with constant circulation.

my 2 cents.

    ergomax as a buffer tank

    Looking to correct a mod con that was piped wrong. 6000 sf house and owner wants everything redone. there is an existing ergomax tank there now, and a munchkin 199k boiler.

    Is there any restriction on using the tank as a buffer tank. I'm using a condensing boiler w/ max output of 190k btus. House has a mixed load of high temp coils and low temp radiant.

    If I have a 190k btu load on a design day and the tank only has a 1" tapping, does this reduce the output that go be forced through the tank.

    Should the full heating load of the house go through the buffer tank?

    Should I only pipe the radiant off the buffer tank.

    I have installed several mod cons before, with indirects and all simialr convectors.

    How would I pipe the primary secondary loops for this.
    Any help would be appreciated. thanks, Mike
