and Passive Annual Heat Storage System.

One module can hold ca. 200 liters, so 2.4 meters high mini garden with 6 modules holds 1200 liters of water. This kind of large water volume stabilizes microclimate for plants and allows automatic watering for a long time.

Inner dimensions are 2100 x 1350 x 600 mm

and the water heater doubles as outdoor fireplace, oven, BBQ and smoker.

The gate is very strong,

clean and minimalist,

reliable

and secure.

Heat energy storage tank can be operated without internal heat exchangers,

with single internal heat exchanger

or with many heat exchangers that have different heat regimes.
