RX 26 BF expansion tank

Вопрос:

The question about expansion tanks. RX 26 BF have a exp.tank 10L capacity. how do you calculate - for what volume of the heating system this tank reasonably?

Ответ:

I confirm the capacity stated in the expansion vessel is the available volume for the water expansion. There is a formula to calculate the volume of the tank based on a system of average dimension (50-60 lt of water) but now I do not remember it, in any case you can find it in internet.
