1 Laddomat 21 For accumulation when using a wood-fired boiler Picture 1 The wood-fired boiler is connected to ……an accumulator tank with by-pass and dwh with...... Laddomat 21…and this is how it works...
2 Laddomat 21 Now it´s time to start the fire Picture 2 The electrical cartridge heats the top of the tank…Picture 2...enough to provide hot water...…and heatingNow it´s time to start the fireThere is no remaining heat from last firing.The boiler and……tank are cold and are not generating any losses.
3 Laddomat 21Picture 3The electrical cartridge heats the top of the tank for a while until…A fire is lit in the boiler…
4 …the temperature increases in the boiler Laddomat 21Picture 4…the temperature increases in the boiler
5 Laddomat 21 Picture 5 The flue thermostat heats up… The built-in check valve is kept……and starts the pump…shut by the pump flow…the water starts to circulate inside the boilerThis stops the boiler cooling down during the start-up firing
6 Laddomat 21 Picture 6 At +78°C, the thermal valve opens… …the tank is being charged with hot water…and cold water from the tank is added…cooling the boiler with pre-heated water
7 Laddomat 21Picture 7A short time after charging begins, the electrical cartridge is shut off by its own thermostat
8 …until it is completely full Laddomat 21Picture 8Thanks to the low flow level, perfect layering is created when the tank is being charged……until it is completely full
9 Laddomat 21Picture 9The thermal valve ensures that the tank is being fully charged……the by-pass flow is completely shut down in the final stagesThe full capacity of the pump cools down the boiler
10 The fire goes out when the fan or damper stops the supply of oxygen Laddomat 21Picture 10The fire goes out when the fan or damper stops the supply of oxygen
11 …and stops the circulation pump… Laddomat 21Picture 11The flue cools down……and stops the circulation pump……the flow ceases…
12 Laddomat 21Picture 12Residual heat from the voiler is transferred to the top of the tank…The radiator return valve adds cold return water…The check-valve opens
13 Laddomat 21Picture 13After a number of hours, there is no more heat in the tank……and the electrical cartridge starts up againThe radiator return valve adds cold return water
14 Laddomat 21This is how the Laddomat 21 works in the event of a power cutPicture 14The boiler is burning at maximum output
15 Laddomat 21This is how the Laddomat 21 works in the event of a power cutPicture 15The tank is being charged…
16 Laddomat 21This is how the Laddomat 21 works in the event of a power cutPicture 16The unthinkable happens…A power cut !!!!!!!!!
17 Laddomat 21This is how the Laddomat 21 works in the event of a power cutPicture 17The pump stops…The check-valve for selfcirculation opensThe fan stops, the air supply is cut off
18 Laddomat 21This is how the Laddomat 21 works in the event of a power cutPicture 18The heat from the boiler is transferred to the tank.The fire can be kept going at limited output until electrical power is restored.The pressure of the natural circulation system fills the boiler with cold water.
