26. Operating a system with accumulation tanks

Ignite the boiler and allow the accumulation tanks to "charge" to the required water temperature
of 90-100°C by the boiler's maximum output operation (2 to 4 loads). Then leave the boiler to stop
burning. Then keep withdrawing heat from the storage utilising three-way valve for a period of time
corresponding to the size of accumulation tanks and the external temperature. In the heating season
(and if adhering to specified min. accumulation tanks volumes – see chart) this could take 1 – 3 days.
If the accumulation method cannot be used, then we recommend using at least one tank of 500 - 1000
l volume for equalising the boiler start-ups and run-outs.

Tank insulation

A suitable solution is joint mineral wool insulation of the particular number of tanks (of required
volume) placed together into a plasterboard structure, or additional filling with granular insulation.
When using the mineral wool, the specified minimum insulation thickness is 120 mm. Another option
is purchasing tanks in a leather-cloth housing insulated by mineral wool (see the price list).

Advantages

The installation with accumulation tanks provides several advantages:
- lower fuel consumption (by 20 – 30%), the boiler operates in full output and at an optimal effec-
tiveness of 81 - 89 % until the complete combustion of the fuel
- prolonged boiler and chimney service life – minimum formation of wood-tars and acids
- possibility to combine it with other heating methods – accumulated electric power, solar collec-
tors
- combination of wall radiators and floor heating
- convenient heating and ideal fuel combustion
- environmentally friendlier heating
