General Information

LK 816 ThermoKit E Eco is a loading group for heating applications with
solid fuel boilers and storage tanks. The loading group is intended to ensure
a high return temperature as well as an optimal temperature stratifi cation in
the storage tank, thus increasing the effi ciency of the system. Tarring and
condensation are prevented which prolongs boiler life.

Installation and Maintenance

LK 816 ThermoKit E Eco is installed in the return circuit between the solid
fuel boiler and the storage tank. The group should be mounted with the drive-
shaft of the circulating pump in a horizontal position. The tempera ture sensor is
attached to the return circuit of the boiler.
The loading group is reversible and can easily be adapted for mounting to the
right or left of the boiler (See Figure 1 & 2 on the back page.)
For trouble-free operation of the heating application the piping should not
allow air pockets to be formed in the system. Should this not be possible air vent
valves have to be installed.
The loading group normally requires no maintenance. The installation should
be checked regularly. Thanks to the three ball valves any part can be changed
without draining the system, should the need for servicing arise.

The function of the loading unit during
the different phases of heating
1. Heat up phase
The water circulates between boiler and loading
group while the temperature of the boiler is rising.
2. Loading phase
The mixing valve starts to open and allows return
water from the storage tank to be mixed with sup-
ply water before it returns to the boiler. The return
temperature to the boiler is kept constant.
3. End phase
The mixing valve is fully open towards the storage
tank. This results in an optimal transfer of heat from
the boiler and the storage tank is filled with supply wa-
ter. When the boiler has cooled the electronic controller
prevents re-circulation from storage tank to boiler.
4. Self-circulation
In case of power failure or pump breakdown the
electronic controller can be manaully operated and
the storage tank is loaded through self-circulation.
