5.4.8 CONNECTION TO THE ACCUMULATION TANKS

System of the connection is based on warming the accumulation tanks, where is the accumulated

warmth from accumulation tanks gradually drained according to the requirements of heated space. Dur-

ing the bioler operation at full output are accumulation tanks warmed at 80–90 °C. Heating with accu-

mulation tanks in connection with ATTACK SLX boiler brings several advantages. Main advantages are

higher efficiency, lower fuel consumption, prolonged lifetime of the boiler, more frequent operation,

minimal creation of acids and condensates, higher comfort, lower risk of boiler overheating and fuel sav-

ing.

Recommended volume of the accumulation tank for ATTACK SLX 25 boiler is 2000 l (for other outputs

see technical parameters). Boiler is able to produce 180 kWh of energy at one loading of the hard wood

to the feeding chamber (it is ca. 7 hours of operation at full 25 kW output). It correspond to charge of

2 000 l accumulation tank from 20 °C to 90 °C if there is no energy offtake (that is why is necessary to

keep in mind by choosing the size of accumulation tank, that boiler must be operated according to the

size of accumulation tank. It means that, if you have 2000 l tank, load the wood chamber fully. If you

have 1000 l tank, load the chamber halfway – if there is no energy offtake from the accumulation tank). If

the accumulation tank is charged (bottom temperature of the accumulation tank achieves 70 °C) and

boiler achieved set boiler temperature, do not load the wood to the boiler. If you would load the wood to

the boiler in this state, wood would not be combusted (boiler has already achieved set temperature and

fan has turned off). It would get dry and condensates would create in the feeding chamber, what lowers

boiler lifetime. It is necessary to fill the wood at the time when the accumulation tank is almost dis-

charged.

Example 1:

Outside temperature of the environment is −5 °C and heat loss of the object is 10 kW by this tempera-

ture. Boiler has 25 kW at the full output operation. Accumulation tank with volume 2000 l is discharged

(its upper and bottom temperature is 20 °C). The heating system (to cover heat loss) drains 10 kW output

from accumulation tank and boiler has 25 kW output, accumulation tank will be heated by the output of

15 kW – difference between them. 15 kW output makes energy of 105 kWh by full loading of the cham-

ber with hard wood and time of the operation ca. 7 hours. Energy of 105 kWh warms accumulation tank

from 20 °C to 65 °C. It means, that this is the safe economic operation without putting the boiler out of

operation or draining excessive warmth to the waste (boiler was cooled by the aftercooling circuit). Boil-

er is able to cover the heat loss for up to 15 hours at one wood loading.

Example 2:

Outside temperature of the environment is +3 °C and heat loss of the object is 5 kW by this temperature.

Boiler has 25 kW at the full output operation. Accumulation tank with volume 2000 l is discharged (its

upper and bottom temperature is 20 °C). The heating system (to cover heat loss) drains 5 kW output from

accumulation tank and boiler has 25 kW output, accumulation tank will be heated by the output of 20

kW – difference between them. 20 kW output makes energy of 140 kWh by full loading of the chamber

with hard wood and time of the operation ca. 7 hours. Energy of 140 kWh warms accumulation tank from

20 °C to 80 °C. It means, that this is the safe economic operation without putting the boiler out of opera-

tion or draining excessive warmth to the waste. If the heat loss of the object would be constant all the

time – 5 kW, charged accumulation tank would be able to cover heat loss for about 28 h, what is togeth-

er with operation time up to 35 hours without need of wood loading.

That is why it is necessary to keep in mind, that boiler should be loaded only with amount of wood

necessary for charging the accumulation tank, because pointless overheating might lead to putting the

boiler out of the operation or removing excessive warmth to the waste. This is uneconomical and re-

quires activation of the safety element – aftercooling loop.
