Suppliers that help with supply detail and design of Radiant Heat

When I did my Solar I called AltE store and told them what I wanted, and they put together a quote of everything I needed, and it all worked out in the end.
Are there similar suppliers for Radian Heat?
My heating source is not common (Sanden Eco2), but from a plumbing perspective, it's just a two zone radiant system with two heat exchangers (pre-heat with drain-back solar system and exchange heat via required Taco x-block with Sanden Eco2 tank).

    What did your heat loss calculation come in at ?
    I have enough experience to know , that I dont know it all

    Do you need a load calculation and design? You can do on yourself with several online sources. A hydronic rep, wholesaler or the manufacturer will often provide designs. Expect to pay for the work, and support the wholesaler that may do a freebie.

    Download the free Uponor CDAM, it takes you through all the steps for loads, and sizing.

    My hydronic heat system is supplementary to the multizone 36K BTU Fujitsu mini-split that already exists--when radiant runs out of juice, mini-split will kick in (or in case I am out of power, maybe instant propane heater kicks in, if I can find a suitable one).

    Vendor I found is BlueRidge. I will share details of own design separately, it got too complicated for paper, so I bought Visio. Will also check out the resource recommended above.

    Nice graphics. What did you use? Is that diagram missing some check valves and pump?

    The heat pump, buffer and tankless are all potable water? The HX separates the hydronic side?

    It's usually the opposite. I don't think you want to keep running fresh water through the HP.
    Seems like you will lime it up?

    Here is an option. A 3 pipe buffer, direct to load will drive the HP efficiency up as the coldest return comes back. Direct to load so the tank only comes into play when loads are satisfied or smaller than hp output.

    Heating water in HP, tank and hydronic. Potable water after the FPHX.

    I used Visio with some stencils from Tekmar (the colored stuff).
    First time I used Visio in at around a decade.. but it got too busy to do on paper.
    Given my minimal plumbing background , I am sure I might be missing some check valves (at least one on return based on below), but the pumps are as follows
    1) one in Sanden Air to Water unit (factory built in)
    2) one in Taco x-pump (factory built in)
    3) one in solar drainback system (DYI system with some old copper panels)

    I am considering a prefab system by RHT for the Taco stuff sold by BlueRidge.
    The image below don't show it, but they sell units with two taco sentry (two zone) just like I had in my diagram (they just sent me a quote this evening, they're on west coast)

    Simplified based on feedback from BlueRidge

    Is the potable water in the buffer tank? If so be sure the A2WHP is rated for potable water. Although I would not continue to run water through a HP like that.

    Potable water is only in the coil.

    And here I tried visio for about 5 minutes one time and gave up. I guess I should give it another go

    Combi heat is a supportable config for SANCO2 with a Taco X-Pump in config like above, which at this point is pretty much 'stock' other than pre-warm. They're not big fans of warm return.
