Wall-Mounted Buffer Tank

New, small apartment building in Berkeley going up where they want to use a Navien combi heater for DHW and radiators in each unit. The smallest Navien NCB is 150,000 BTU's and will modulate down to 12,000 BTU's. The total radiator load is ~10,000 and they want it zoned; micro-zoning is a problem. You hardly ever see buffer tanks out West here, but this is a job that needs one.
The mechanical area is tiny. Does anyone have a recommendation for a wall-mounted buffer tank?

8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

How many gallons? If a small 6 or 12 gallon electric water heater, you can find wall brackets for them or have one fabed. I had a sheetmetal guy bend a bracket that also served as a pan.
This was a small electric set up for a bathroom floor and shower wall I did years ago.
Remember over 8 lbs per gallon, so it will take a good solid wall to hang much capacity.Bob "hot rod" Rohr
