I have a Burnham 204HNSL-BEI2 boiler controlled by a single thermostat which currently serves about 1400 square feet of living space via copper pipes and varying sizes of baseboard fixtures in the various rooms.
I'm building a 24x26 garage addition with radiant heat in the slab. A contractor is installing the appropriate amount of radiant pex loops in the slab, and I'm planning on finishing the installation by connecting the radiant pipes in the slab to my existing boiler (the boiler is about 20 feet away from where the radiant pipe will connect). I have had a heat load analysis done on my home to confirm that my boiler has the capacity required to serve a new zone.
I'm interested in doing this work myself, and would like some help with the planning process. My understanding is that I will need to add a zone to my existing boiler along with a heat exchanger to separate the glycol system that heats the slab from the rest of the home baseboard fixtures, a mixing vale to regulate temperature of the glycol, a manifold to connect the delivery and return loops, and I'm wondering what else I need to think about for planning purposes.
What else should I think about as I'm doing this early planning work? Let me know if you need anything additional from me (further description, photos of my boiler, etc) in order to help point me in the right direction.
