Description

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.

LK 440 EasyHeat is available in two versions, with 3-phase 400V or 1-phase 230V. The total output capacity on 3-phase 400V is 9 kW and works in two steps of 4.5 kW. The total output capacity on 1-phase 230V 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 vent valve. Connection to the under floor heating manifold or heating system is simple, using steel-reinforced flexible hoses. Temperature regulation is controlled by the boiler’s operating thermostat.
