ENERAL FEATURES
-STR series soild fuel fired boiler is designed for heating both residental and industrial buildings.
-Beside Professional installation, preconditiion for correct functionning of the boiler is required chimney
thrust and correct operration.
-STR series boiler soild fuel fired boiler is designed for heating system which are suitable for forced
circulation system only.
-STR series boilers are available in three output series 25, 35 and 45kW.
-
Attached to the boiler body are sheet metals covers are fitted on the inside with termal insulation.
-To ensure that the boiler functions correctly and runs economically, it is important that its nominal
output is equal to the thermal losses of the heated premises.
- Choosing a boiler of insufficient output will result in inadequate heating of the premises,and thus failure
to provide a heating comfort.
-Choosing a boiler of unnecessarily high output will result in the boiler not running in Full output,and as
a consequence in tarring and dewing.
