What is the difference between cast iron vs. stainless steel for an electric boiler?
We are installing hydronic concrete slab heating. the slab has already been poured, i thiink the HVAC guy did not use O2-barrier PEX tubing. As i understand it, this means that a cast iron boiler cannot be used. true? how good are the stainless boilers vs cast iron (reliability), what are the pros and cons, which one would you use? Electro seems to come up in my searches, probably a mid-size 34k to 51k BTU/hr seems appropriate. i was surprised to see that they seem cheaper than the cast iron models... but i'm not really sure what features i should be comparing. any education here would be appreciated!
