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...

slide2

Laddomat 21

The electrical cartridge heats the top of the tank…

Picture 2

...enough to provide hot water...

…and heating

Now it´s time to start the fire

There is no remaining heat from last firing.

The boiler and…

…tank are cold and are not generating any losses.

slide3

Laddomat 21

Picture 3

The electrical cartridge heats the top of the tank for a while until…

A fire is lit in the boiler…

slide4

Laddomat 21

Picture 4

…the temperature increases in the boiler

slide5

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 boiler

This stops the boiler cooling down during the start-up firing

slide6

Laddomat 21

At +78°C, the thermal valve opens…

Picture 6

…the tank is being charged with hot water

…and cold water from the tank is added

…cooling the boiler with pre-heated water

slide7

Laddomat 21

Picture 7

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

slide8

Laddomat 21

Picture 8

Thanks to the low flow level, perfect layering is created when the tank is being charged…

…until it is completely full

slide9

Laddomat 21

Picture 9

The thermal valve ensures that the tank is being fully charged…

…the by-pass flow is completely shut down in the final stages

The full capacity of the pump cools down the boiler

slide10

Laddomat 21

Picture 10

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

slide11

Laddomat 21

Picture 11

The flue cools down…

…and stops the circulation pump…

…the flow ceases…

slide12

Laddomat 21

Picture 12

Residual heat from the voiler is transferred to the top of the tank…

The radiator return valve adds cold return water…

The check-valve opens

slide13

Laddomat 21

Picture 13

After a number of hours, there is no more heat in the tank…

…and the electrical cartridge starts up again

The radiator return valve adds cold return water

slide14

Laddomat 21

This is how the Laddomat 21 works in the event of a power cut

Picture 14

The boiler is burning at maximum output

slide15

Laddomat 21

This is how the Laddomat 21 works in the event of a power cut

Picture 15

The tank is being charged…

slide16

Laddomat 21

This is how the Laddomat 21 works in the event of a power cut

Picture 16

The unthinkable happens…

A power cut !!!!!!!!!

slide17

Laddomat 21

This is how the Laddomat 21 works in the event of a power cut

Picture 17

The pump stops…

The check-valve for selfcirculation opens

The fan stops, the air supply is cut off

slide18

Laddomat 21

This is how the Laddomat 21 works in the event of a power cut

Picture 18

The 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.
