General scheme: heating system 2
Combined heating system : Electric boiler + fireplace
stove , branches A and B, backup UPS 300.
Separating valves – heat circuits I- II:
Designed for separation of the heat circuits A
and B.
Heat circuit B: A part of the heat circuit.
Only for the fireplace stove.
Heat circuit A: General heat circuit. Both
devices in operation at a time.
Instal a thermoregulating valve , e.g .ESBE
TV25, opening temperature 60oC. When this
temperature is reached, the valve opens , and
the liquid from the heat system B (or A+B) is
let in the fireplace stove circuit (3-1).
The
inlets 1 and 3 of the valve are open – to
provide minimum temperature required for the
reverse water.
The recommended temperature gradient is 75-
60 °C. To provide this, the following
conditions must be met:
B – Connection to the parts of the system
A – connection to the general heating system
