Table 1: Technical data - Indirect
Notes:
1. Indirect cylinders tested in accordance with BS EN 12897:2006.
2. Heat up time from cold through 45°C, based on a flow temperature of 80°C +/- 2°C & normal volume.
3. Although the primary coil pressure rating is 1.0MPa (10bar) the 2 port zone valve and coil compression
nuts supplied with the cylinder is only rated 0.86MPa (0.86 bar). If the cylinder is to be plumbed into a
system delivering 1.0MPa (10 bar) a suitable 2 port zone valve and the coil compression nuts supplied will
have to be sourced.
