BOLLY® XL
- HEAT EXCHANGERS TECHNICAL DATA
Data have been calculated on following basis:
1) Primary circuit at T1 and proper energy source;
2) Production of DHW in continue way from 10 °C at t2;
3) DHW that can be taken in the first 10’ and in the first hour from storage at 60°C, input 10°C and
output 45°C;
4) Sanitary water according to UNI CTI 8065.
