GENERAL INFORMATION
The LK 440 EasyHeat is a complete portable electrically-
heated boiler. It is primarily meant to be used as a tempora-
ry 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 3 kW and it can be
manually set between 2 or 3 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.
LK 440 EasyHeat is factory wired and complete with a
1-phase 230 V electric plug. Temperature regulation is con-
trolled by the boiler’s operating thermostat.
