Purpose
Solid fuel water heating boiler
Kalvis 2-30U
,
Kalvis 2-40U
(hereinafter referred
to as boiler) is designed for heating of various premises where central heating
system is installed with natural or forced circulation and closed or open expansion
system. The boiler operates most efficiently under nominal taken thermal power, if
operating with lower power, accumulation capacity is recommended to use.
