    I'm looking at boiler replacement job with a total house load of about 75,000 BTU's. I'm thinking about a mod-con with a buffer tank. The house has 6 existing zone and a 80 gallon indirect, the zones are kinda small and only doing a couple rooms each. They have a interior bathroom that has a radiant floor which is about 1,200 BTU's.
    How would you guys pipe in this radiant zone? Mixing valve? I series valve? something else?

    Yes, the bathroom is its own zone. It currently have a three way mixing valve off the boiler. It has a t87 thermostat controlling the circulator.

    Total houe load

    Is that a calculated heat loss?  Why so many zones?  Might be an opportunity to simplify things...

    Yes, that is the total house load. He want to keep almost every room on its own zone.
