Table 7 Assignment of heat exchanger ECO 7 to boiler size
The tube bundles highlighted in bold
correspond to the assignment for the limit
output of the UNIMAT UT-L.
If the boiler is operated with low heating
output, a smaller flue gas heat exchanger
can also be selected under certain
circumstances.
