Design

The LK 810 ECO loading unit ensures a minimum return-water temperature into the solid fuel boiler, which increases boiler efficiency, prevents tarring and considerably prolongs the lifetime of the boiler. LK 810 ECO eliminates the risk of destructive thermal shock caused by surges of cold water and renders a more effective burning. The boiler quickly reaches the right working temperature. In the end phase of the firing an automatic balancing valve closes the by-pass loop. This results in a maximum supply from boiler to storage tank. LK 810 ECO is for boilers with a capacity up to 75 kW.

LK 810 ECO loading unit comes in two versions, with or without backflow preventer. With a backflow preventer the LK 810 ECO automatically allows self-circulation of the remaining hot water to the storage tank, as soon as the fire has gone out or in case of power failure. Back flow from storage tank to heating boiler is prevented.

Mounting/Installation

LK 810 ECO is mounted upright on the return pipe. The loading unit is reversible and can be installed on the right- or left-hand side of the heating boiler.

Operation and Maintenance

LK 810 ECO normally requires no maintenance. The loading unit has three ball valves. Any part can be changed without draining the system.
