General Information

The LK 440 EasyHeat 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 construction 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
heating system is simple, using steel-reinforced flexible hoses.
LK 440 EasyHeat is factory wired and complete with a 3-phase
400 V electric plug. Temperature regulation is controlled by the
boiler's operating thermostat.
