... here we have the concept of a communal pool with large water basins and separate tubs: this is about tubs. So I designed a tub that was created under the aspects - no fittings, automatic filling and emptying of the tub - with automatic overflow, so water always runs - and is always drained away!here we have a japanese onsen principle, i.e. hot natural water, from the water cycle of the heated, moving water that we use for air heating.So water is heated with fuel gas and the water is used as steam to heat the air. this is how we create indoor thermal systems.step, igs
