We have a 900-liter (240-gallon) energy storage tank (Weishaupt) for our heating room in the basement, which weighs a total of 1.2 tonnes (1.3 tons) including water. Since this unit stands on three "feet," each foot bears about 400 kilograms (880 pounds).
Here is the information about the floor layers: slab 25 cm (10 inches), vapor barrier (Katja), 6 cm (2.5 inches) of aluminum-coated insulation, another 5 cm (2 inches) of aluminum-coated insulation (11 cm / 4.3 inches total insulation), 6.5 cm (2.6 inches) cement screed, 1.5 cm (0.6 inches) tile covering. The total buildup is approximately 19 cm (7.5 inches).
Do you think I can just place the storage tank on this surface? My brother-in-law (our heating company!) says I can. Maybe I am just being too cautious... What options are there to make it “safe”…
Greetings from Swabia!

Hello
This isn’t exactly my trade, but in the medium term this will lead to significant settling of the screed and possibly to cracks.
I would install a bonded screed in this area.
Another option is a board made of, for example, foam glass on the raw concrete with a metal covering.

Or a load distribution plate. I placed my 500 L (132 gallon) buffer tank on 10 cm (4 inch) Jackodur insulation (for thermal insulation underneath), then 20 mm (0.8 inch) dry screed panels, and on top of that a 25 mm (1 inch) OSB board as the load distributor. My buffer stands on a ring with a diameter of about 50 cm (20 inches), so the weight is now spread over approximately 2 m² (21.5 ft²). My heating engineer said this wasn’t really necessary, but I feel safer doing it this way.
