6.3. Accumulation
The best results in heating gives boiler’s connecting with an accumulation tank. Such installation
causes less wood using - even up to 40 %. Gasication process (if it runs in optimum way)
generates large gas quantity, heating system however is characteristic for large uctuation
amplitude in warmth requirement scope. Gasication process is set only in certain way, heating
system uctuaction change more often, room might get overheated or some extra gas can
get through the chimney. Accumulation system allows for gas storing in an accumulation
tank. Heating system is contributed by accumulation tanks for about 48 h (depending on
tanks’ capacity and thermal conditions - at about 50 l of water for 1 kW of power). If the boiler
cooperates with accumulation tank, its long lasting is lengthened.
