Radiant Designer

I am getting ready to build a steel building with in-slab radiant heat. I am looking for advice on finding and selecting a system designer for a DIY install. Any advice would be appreciated.

I wouldn't mind doing it except that I'm swamped right now. Try Harvey Ramer. He's great.

Just do an onsite search. He's on here regularly.

Is this building standing yet ? Now far along are you ? Feel free to contact me

I would be happy to help. I can share some of my previous design work to give you an idea of what you will get.

For some reason my 60 year old Holiday Burnham NG Boiler after 22 straight years of worries free use, crapped out on me and I need to replace it. My old system was a 95’ BaseRay cast iron base board shot gun system with one thermostat and one continuous running circulating pump.

I would like my new system to be a Burnham K2-150 four zone, zone valve system with one Alph2 ECM pump.
Zone one will be a high heat (180) in joist pex-al-pex loop.
Zone three will be an in slab out building and
zone 4 will be a 50 gal Burnham indirect HWH.

Question one.. Will be buying a pre-made secondary setup with one Alpha 2 ECM and for zones set up with zone valves.

How do they know the Alpha2 will work without knowing what the total head for the whole system will be?

Question two.. Setting up a reverse return distribution system using two straight 1" runs down one side of my ranch in the basement and running four 3/4", nine joist bay loops starting at the supply run and ending with the return run for zone one. Each loop will have a diverter T, flow meter/valve and an isolation/purge valve.

Do I need to put in a balancing valve at the end of the two 1” straight runs?

Do I have to put in a zone valve in each of the four ¾” sub loops even though I have a flow meter/valve?

If I can use my flow meters, should they be Velocity or Volumetric? Guessing volumetric.


Does anyone see any potential problems with the direction I’m taking?

Thanks
