Need to replace this leaking ssu60c indirect. It's doing domestic, two radiant zones and one high temp (140ish) zones off the secondary coils. Ssu60c being supplied by a steam boiler. Trying to figure the best way to replace. New ssuc? New boiler?, mod con, ci? Combi? Zones off steam boiler? New everhot external tankless coil? I really think putting back ssuc is not the best option. I'd rather leave the steam boiler to do steam only. Too many option.
Thanks

You have a lot of stuff going on.
I like indirect water heaters.0 -
You’ve got the famous Hoffman Differential Loop. Be careful which heating guys you have working in your home0

Does he? How'd you figure that out, Gary ( @GW )? In that case -- yes indeed. He needs to have someone who does know what they are doing working on it!GW said:You’ve got the famous Hoffman Differential Loop. Be careful which heating guys you have working in your home

With ALL that complexity you have going on there you are prob MUCH better off cutting out the hot water loop you have running all that steam.
Keep the steam boiler just doing the steam .
Looks like you have gas....
I would prob do a separate HW boiler to run the IDWH and the hot water zones.
OR you could run just the High temp loop off the boiler and do a Wall hung mod con to do the radiant and the Indirect.0 -
Thanks for the responces, I am the heating guy. GW, good catch with the hoffman loop, looked it up to see what it does.
Kcopp, I was thinking along those lines also. Not sure to go cast iron boilet or something high efficiency.
Thanks again0 -
