<strong>Laddomat</strong> 21-60 and 21-100<br />
ensures that<br />
the boiler charges the tank with high and even<br />
output<br />
the boiler burns at optimum effi ciency<br />
charging functions through self-circulation in the<br />
event of a power cut<br />
the residual boiler heat is used<br />
This is how <strong>Laddomat</strong> 21<br />
works<br />
When you have lit the boiler the pump is<br />
started by the fl ue thermostat and the boiler<br />
quickly heats up. 15–30 minutes after lighting,<br />
<strong>Laddomat</strong> 21 has fi lled the upper section of<br />
the tank so that you obtain both hot water<br />
and heating.<br />
Separation* means that the hot water at<br />
the top does not mix with the cold water<br />
underneath.<br />
Separation = sharp division between hot lighter water<br />
and cold heavier water.<br />
An automatic shunt control with the room<br />
temperature sensor ensures that the return<br />
water from the radiators is as cool as<br />
possible.<br />
This means that separation is maintained,<br />
which is very important for the tank’s<br />
storage capacity.<br />
The self-circulation valve in <strong>Laddomat</strong> 21<br />
ensures that residual heat in the boiler is<br />
transferred to the tank top as the heat in the<br />
tank is used.<br />
THE BASIS<br />
FOR EFFICIENT<br />
WOOD FIRING<br />
When the whole tank is full <strong>Laddomat</strong> 21<br />
closes the by-pass port, so that even the<br />
last heat of the embers is charged to the<br />
tank.<br />
Then the fl ue thermostat ensures that<br />
the <strong>Laddomat</strong> 21 pump stops, so that the<br />
residual heat in the boiler is transferred to<br />
the tank (see below).<br />
<strong>Laddomat</strong> 11-30 ensures that<br />
the boiler charges the tank with high<br />
and even output<br />
the boiler burns at optimum effi ciency<br />
This is how <strong>Laddomat</strong> 11-30<br />
works<br />
The circulation pump is started either when the water<br />
thermostat reaches around 80°C (or the highest temperature<br />
before it actually starts boiling) or breaks the circuit with its<br />
built-in operating thermostat, or alternatively, the damper<br />
closes, which creates an emission of tar in the boiler.<br />
In start up mode the water only circulates around the boiler.<br />
When the boiler water reaches operating temperature and<br />
circulation has started, <strong>Laddomat</strong> 11-30 mixes hot water from<br />
the top of the tank with cold water from the bottom of the<br />
tank. The water temperature at the bottom on the boiler stays<br />
at 72–80°C.<br />
In the fi nal phase the tank is charged by <strong>Laddomat</strong> 11-30<br />
choking the by-pass port and the whole pump fl ow cools the<br />
boiler.<br />
To avoid unnecessary heat loss after completed fi ring, the<br />
pump thermostat’s setting should be as high as possible to<br />
make the circulation pump come to a fast stop. A suitable<br />
setting is approx. 80–90ºC.<br />
The boiler will subsequently cool down completely without<br />
causing any heat loss from the tank.<br />
A simple way to bring the pump to a fast stop after completed<br />
fi ring is to connect the pump via a fl ue thermostat.

<strong>Laddomat</strong> Flue thermostat<br />
To start and stop the charge pump in <strong>Laddomat</strong> 10, 21,<br />
21-60, 21-100, or 11-30.<br />
The fl ue thermostat starts the pump as soon as the<br />
temperature of the fl ue rises to a predetermined level,<br />
after fi ring starts. In <strong>Laddomat</strong> 21 the pump fl ow closes<br />
the self-circulation valve with the tank. Hot water from<br />
the boiler top is pumped directly into the boiler bottom<br />
= the boiler quickly becomes hot.<br />
Thermomatic K<br />
Thermomatic K (TMK) is a constant regulator for controlling a turning<br />
mixing valve with a 90 degree opening angle.<br />
TMK can be used for constant maintenance of both cooling and<br />
heating.<br />
Minimum time between fully open and closed positions is 120 seconds.<br />
TMK is suitable for all installations with constant fl ow such as radiator<br />
and underfl oor heating circuits, charging of accumulator tanks etc. This<br />
version is not suitable for domestic hot water control.<br />
The temperature scale is 10–80°C.<br />

When the wood fi re goes out, the pump stops as soon as<br />
the fl ue cools down. In <strong>Laddomat</strong> 21 the self-circulation<br />
valve opens so that cooled water from the tank bottom can<br />
transfer residual heat in the boiler to the tank top.<br />
When <strong>Laddomat</strong> 10 is used a water thermostat should be<br />
installed in parallel with the fl ue thermostat. This is as extra<br />
security if the boiler should boil due to too large a bed of<br />
embers.<br />
