Structure
The LK Electric Portable Boiler is a complete
portable electrically-heated boiler. It is primarily
meant to be used as a temporary heater, e.g. for
drying concrete slabs installed with under floor
heating and for heating buildings under construc-
tion installed with a under floor heating system.
The boiler has a total output capacity of 9 kW
and it works in two steps of 4.5 kW.
The boiler is supplied complete with a circulation
pump, an expansion tank, and auxiliary devices
including a safety valve and air-bleed valve.
Connection to the under floor heating manifold/
heating system is simple, using steel-reinforced
flexible hoses.
The boiler is factory wired and complete with a
3-phase 400 V electric plug.
Temperature regulation is controlled by the
boiler’s operating thermostat.
