Laddomat Brochure - Euroheat

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

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

When the wood fi re goes out, the pump stops as soon as
the fl ue cools down. In Laddomat 21 the self-circulation
valve opens so that cooled water from the tank bottom can
transfer residual heat in the boiler to the tank top.
When Laddomat 10 is used a water thermostat should be
installed in parallel with the fl ue thermostat. This is as extra
security if the boiler should boil due to too large a bed of
embers.
Thermomatic K used for cooling a boiler
Thermomatic K used for cooling a boiler when the
distance between boiler and tank is big.
Thermomatic K also used for keeping a constant
tempetature for underfl oor heating.
