1 Maximum area of heated rooms estimated for unit heat demand q=80 W/m2.

2 Fuel tank capacity for bulk density of eco-pea coal equal to 0,8 kg/dm3.

3 Boiler weight depends on its additional equipment.

 

Height of boiler can be additionally adjusted by means of provided levelling legs. The regulation of legs varies from 38 to 50 mm.

 

ATTENTION! When ordering the SIGMA E boiler the customer should specify on which side the container should be located (right or left).

 

Additional equipment components shall be added during ordering of the boiler because there is no possibility of installation in the future.
