Very nice setup. That kind of looks like my Froling DHW tank, about 110 gallons or so. I haven't run my pellet boiler much at all, but use the DHW tank all the time. The Burnham cast iron boiler heats it up. It's well insulated. I figure the long run time does it good. The burn chamber of the oil boiler looks pretty good when I do the yearly cleaning-not much stuff from cleaning the passageways either.
Something to maybe think about is unintended flow and the use of check valves.
I'm sure the Froling will come with a bunch of instrumentation, but maybe something remote, maybe even cloud, to avoid trips downstairs.
I put my pellet boiler on solid concrete blocks, what they call 'termite blocks'. I hadn't really thought about how to get the boiler off the pallet and onto the blocks. You probably have a lot more to think about without a door to the outside from the basement.
The DHW tank is what was recommended by Boithermic here in Canada, the Froling dealer. Its made by a Canadian company I think, Thermo2000. Its an indirect DHW heater thats very efficient with very fast recovery times.

Yes I was wondering about some check valves but to be honest no matter what scenario I play out whether it be oil boiler doing the heating, Froling, Storage, etc., I cant really see where there is a need for one. There are scenarios wher the water will have two possible flow paths but water like electricity will take the path of lease resistance (head) so i think im good.
Of course the circulator pumps have built in checks. With that said, if you see any place where you think I would need a check please dont hesitate to comment, thats why I posted here, really looking for improvements or for someone to point out anything I missed. I am a instrumentation and controls tech by trade but im sure i dont know everything with hydronic heating even though ive been around this stuff for some time.
Yes there is an option to purchase the Froling Touch Display which can be connected to your home modem and you can then view parameters anywhere that has an internet connection. With that Display it allows you to use Frolings free app and portal, Froling Connect. The display is a $700 option so im on the fence with it right now.
