1 Picture 1 For accumulation when using a wood-fired boiler The wood-fired boiler is is connected to to an accumulator tank with bypass and dwh with Laddomat 21 and this is is how it it works...

2 Picture 2 The electrical cartridge heats the top of of the tank...enough to to provide hot water... and heating Now it s time to start the fire There is is no remaining heat from last firing. The boiler and tank are cold and are not generating any losses.

3 Picture 3 The electrical cartridge heats the top of of the tank for a while until A fire is is lit lit in in the boiler

4 Picture 4 the temperature increases in in the boiler

5 Picture 5 The flue thermostat heats up and starts the pump the water starts to to circulate inside the boiler The built-in check valve is is kept shut by the pump flow This stops the boiler cooling down during the start-up firing

6 At +78 C, the thermal valve opens Picture 6 the tank is is being charged with hot water and cold water from the tank is is added cooling the boiler with pre-heated water

7 Picture 7 A short time after charging begins, the electrical cartridge is isshut off by its own thermostat

8 Picture 8 Thanks to to the low flow level, perfect layering is is created when the tank is is being charged until it it is is completely full

9 Picture 9 The thermal valve ensures that the tank is is being fully charged the by-pass flow is is completely shut down in in the final stages The full capacity of of the pump cools down the boiler

10 Picture 10 The fire goes out when the fan or or damper stops the supply of of oxygen

11 Picture 11 The flue cools down and stops the circulation pump the flow ceases

12 Picture 12 Residual heat from the voiler is is transferred to to the top of of the tank The radiator return valve adds cold return water The check-valve opens

13 Picture 13 After a number of of hours, there is is no more heat in in the tank and the electrical cartridge starts up again The radiator return valve adds cold return water

14 Picture 14 This is how the Laddomat 21 works in the event of a power cut The boiler is is burning at at maximum output

15 Picture 15 This is how the Laddomat 21 works in the event of a power cut The tank is is being charged

16 Picture 16 This is how the Laddomat 21 works in the event of a power cut The unthinkable happens A power cut!!!!!!!!!

17 Picture 17 This is how the Laddomat 21 works in the event of a power cut The pump stops The check-valve for selfcirculation opens The fan stops, the air supply is is cut off

18 Picture 18 This is how the Laddomat 21 works in the event of a power cut The heat from the boiler is is transferred to to the tank. The fire can be kept The fire can be kept going at limited output going at limited output until electrical power is until electrical power is restored. restored. The pressure of of the natural circulation system fills the boiler with cold water.
