Table 5 Technical data
* Greenstar CDi Compact boilers are fitted with a flow
regulator set to achieve a 40°C temperature rise. This
ensures comfortable bathing during the colder winter
months.
** All Worcester Greenstar boilers are tested in an
acoustic chamber to sound level and there may some
differences in situ dependant on installation site i.e.
corners of rooms, fabric of property walls.
