With two water tanks: one 300 litre for sanitary purposes and one 500 litre tank for the floor heating. The 300 litre tank will have priority over the other one so that it heats up first before the other bigger tank. If the water for sanitary purposes isn't heated up till the wanted 65 degrees C then another automatic (mechanic or electric) 3 way valve should step in and redirect the water through the central heating first. The bigger 500 litre tank should be heated up only after the other tank has reached his desired 65 degrees.[ 本帖最后由 patty-chu 于 2012-3-27 09:32 编辑 ]

有两个水箱的:一个用于卫生的为300升,一个用于地板采暖的为500升。 300升的水箱优先于500升的,它要先加热,然后再加热大一点的水箱。如果卫生用途的水加热至所要的65摄氏度,再自动加热另一个水箱(机械或电动) 用三通阀将水先导向集中供热。较大的500升的水箱只能在300升的加热到所需的65摄氏度后才能加热。
