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

2 Termoventiler AB Laddomat 21 The boiler and… The boiler and… There is no remaining heat from last firing. There is no remaining heat from last firing. …tank are cold and are not generating any losses. …tank are cold and are not generating any losses. Now it´s time to start the fire The electrical cartridge heats the top of the tank … The electrical cartridge heats the top of the tank …...enough to provide hot water......enough to provide hot water... …and heating …and heating Picture 2

3 Termoventiler AB Laddomat 21 A fire is lit in the boiler… A fire is lit in the boiler… The electrical cartridge heats the top of the tank for a while until… The electrical cartridge heats the top of the tank for a while until… Picture 3

4 Termoventiler AB Laddomat 21 …the temperature increases in the boiler …the temperature increases in the boiler Picture 4

5 Termoventiler AB Laddomat 21 The flue thermostat heats up… The flue thermostat heats up… …and starts the pump …and starts the pump The built-in check valve is kept… The built-in check valve is kept… …shut by the pump flow …shut by the pump flow This stops the boiler cooling down during the start-up firing This stops the boiler cooling down during the start-up firing …the water starts to circulate inside the boiler …the water starts to circulate inside the boiler Picture 5

6 Termoventiler AB Laddomat 21 At +78°C, the thermal valve opens… At +78°C, the thermal valve opens… …the tank is being charged with hot water …the tank is being charged with hot water …cooling the boiler with pre-heated water …cooling the boiler with pre-heated water …and cold water from the tank is added …and cold water from the tank is added Picture 6

7 Termoventiler AB Laddomat 21 A short time after charging begins, the electrical cartridge is shut off by its own thermostat A short time after charging begins, the electrical cartridge is shut off by its own thermostat Picture 7

8 Termoventiler AB Laddomat 21 Thanks to the low flow level, perfect layering is created when the tank is being charged… Thanks to the low flow level, perfect layering is created when the tank is being charged… …until it is completely full …until it is completely full Picture 8

9 Termoventiler AB Laddomat 21 The thermal valve ensures that the tank is being fully charged… The thermal valve ensures that the tank is being fully charged… …the by-pass flow is completely shut down in the final stages …the by-pass flow is completely shut down in the final stages The full capacity of the pump cools down the boiler The full capacity of the pump cools down the boiler Picture 9

10 Termoventiler AB Laddomat 21 The fire goes out when the fan or damper stops the supply of oxygen The fire goes out when the fan or damper stops the supply of oxygen Picture 10

11 Termoventiler AB Laddomat 21 The flue cools down… The flue cools down… …and stops the circulation pump… …and stops the circulation pump… …the flow ceases… …the flow ceases… Picture 11

12 Termoventiler AB Laddomat 21 The check-valve opens The check-valve opens Residual heat from the voiler is transferred to the top of the tank… Residual heat from the voiler is transferred to the top of the tank… The radiator return valve adds cold return water… The radiator return valve adds cold return water… Picture 12

13 Termoventiler AB Laddomat 21 The radiator return valve adds cold return water After a number of hours, there is no more heat in the tank… After a number of hours, there is no more heat in the tank… …and the electrical cartridge starts up again …and the electrical cartridge starts up again Picture 13

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

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

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

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

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