In one of the rooms “Modeller-designer” reader sovetova to reduce evaporation insert into the surge tank a piece of foam, cut to the contour of the tank with a small gap. But not every tank can be inserted the foam, well, rusting capacity will continue.
Meanwhile, there’s an easier way: it is necessary to top up the expansion tank 150— 200 grams of avtol. The effect is simply amazing. Previously, I had to add water to the system two to three times a month, now only once a season, during a routine inspection, if necessary. And again. The walls of the tank at the same is lubricated with oil and not rust.
