20. Thermoregulatory valve
Thermoregulatory valve type, TV 60 (65/70/75) °C is used with
solid fuel boilers. When the boiler water temperature reaches
+ 60 °C , the thermoregulatory valve opens and fluid from the
building heating circuit (2) enters the boiler circuit ( 3 →1). In
-
lets 1 and 3 always remain open. This ensures that the minimum
temperature of the water returning to the boiler is maintained.
The recommended size of the TV 60 (65/70/75) °C
thermoregulatory valve is DN50
21. 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. Afterwards keep withdrawing heat from the storage utilising the 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 adhered to specified min. accumulation tanks volumes – see chart) this could take 1 – 3
days. If the accumulation method (5000 - 6000 litres for DC105S), (8000 - 9000 litres for DC150S) can-
not be used, then the boiler must be connected with at least one tank of 1000 litre volume for equalising
the boiler start-ups and run-outs.

Tanks 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
Installing the boiler with accumulation tanks provides several advantages:
- lower fuel consumption (by 20 – 30 %), the boiler operates in full output and at optimal effective
ness of 89 - 91 % 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 collectors
- combination of wall radiators and floor heating
- convenient heating and ideal fuel combustion
