    Most likely.....

    If you did the heatloss and your hot water needs are not crazy.

    Yes,the 63K is well over the 46K heat loss. How did you calculate the 46K? Every HL program has tons of fudge in it, I bet the real HL is 30K or less

    slant fin

    I used slat fins after i posted about the discrepancies in the calculators. i ordered the boiler yesterday just waiting for it to show. then just have to figure the how i want my zones to go and what controls to run. its so confusing going with this new stuff, if i just put it in like the old it would be easy but a waste of time and money..
