    I agree

    Another reason for heat loss calculations on all your jobs and not add anything to that number for an indirect.



    I see Alpine boilers come up quite often on The Wall, but have no experience with them.  Are they good?



    I subscribed to the US Boiler Report here:

    Thanks, Chris!

    Indirect

    Unless you are using indirects with a very wimpy exchanger (amtrol)., I really have never seen this problem. Using Smart and Heatflo indirects the boiler can generally come up to full fire and run 10 minutes or so, satisfy the load and shut down. There is plenty of room for the boiler to modulate down if needed. Alpine boilers are not common here, maybe they have an issue I have not seen.
