    SlantFIn has a free one that you can download from their site.

    One thing that's often misunderstood in sizing baseboard: with 180* supply and 160* return, you have an AVERAGE water temp of 170* in the BBs, not 180*. You should not use the 560-580 per lineal foot btu output rating. That's for 180* water temp. Use 500 btu per foot for 170* average water temp.

    Does anyone offer straight up heat loss service for a cost? I feel for the amount of people that seem to require it (professional and non-professional) that somebody hasn't decided to make it a source of income for themselves.
    Especially via a planned based submitting via the digital world, then eliminating any requirement for site visit.

    To elaborate on Ironman's thought ...........Also consider, if it's a series loop, each successive set of baseboards sees a low average water temperature, and has a lower output.
