Water circuit - what is it and why is it needed?

The water circuit is a well-known heating system using radiators . It is necessary in houses with a not very good layout, it reduces heat loss from the window, and evenly heats the room.

Traditional boilers without a water circuit heat locally, and if there are more than two rooms in the house that are not in contact with the boiler room, a water circuit is simply necessary, because in its absence, remote rooms will not warm up sufficiently.

Heat loss in them will be very high, and temperatures often do not even reach optimal for living and long-term stay.

In addition, in houses with stove heating, corners often freeze . A water circuit will avoid this problem.
