7.2. DESCRIPTION OF SCHEME OPERATION WITHOUT ADDITIONAL BOILER AND
FLOOR HEATING
The pump (P) pumps the water out of the heating elements and pushes it through the boiler into
the heating elements (see scheme 7.2.). Through balance faucet (bk l) the heated water flows into the
nearest radiator, which can operate in a self-flowing manner to protect the boiler from overheating
(radiator without a thermo valve) in case the power went off.
Hereafter the heated water flows through the non solid fuel boiler 2k (if such is available), which
turns on as the boiler 1k stops burning or turns off when the boiler 1k is supplying the hot water
thanks to internal automatics. If the boiler 2k is available the bolt (3) is turned off, if it is not – the bolt
is turned on.
Hereafter the heated water flows through the water heater (B) and the bolt (3). If the heater input
is of a sufficient diameter, the bolt (3) is turned off – as the water flows only through the heater, more
water is heated.
After the heating domestic water, thermofication water flows to the radiator system.
Thanks to the pump (P) the water abundantly circulates through the flow distribution valve (T-
3-20-50), which, due to the sensor, directs a part of the colder flow into the radiatior system as the
returning flow is warmer that indicated (40°)
maintained a stable indoor heat, even in the absence of thermovalves.
A circulation pump with the power of 25 – 60 W is enough for a 10kW boiler, 40 - 80 W for a
20 kW boiler and 50 – 100 W for a 40 kW boiler.
(bk-1)- a balance faucet of a safety auto flow radiator, through which the flow is determined to
make the radiator reversible pipe 40°C cooler than the infusion pipe.
(7) – collapsible connectors – by releasing them the node may be reversed to another side of the
boiler.

8.1. THE MOST ECONOMICALLY FUEL BURNS DOWN IN THE BOILER WHEN IT IS

Switching valve (6) when burning firewood logs must be lowered, when coal is burning – it must
be lift up (see fig. 2.1.). When loading fuel, the air distribution (9) must be lifted up; therefore take a
ring at the cable end (12) hanging in the right above the firebox doors, pull down and put on a hook
(13). Use the air distributor (9) (see fig. 8.3.) then heating
longer one - in the middle and shorter - at the side. It is useful to fill spaces between firewood logs with
sawdust or fine tree waste.
