1. Introduction
The SCX Solar cylinder is a high quality stainless steel unvented cylinder designed for use with all
solar systems to provide hot water from a cold mains water supply of between 3bar and 12bar.
Reduced performance is available at lower pressures but the units are not suitable for pressures
lower than 1.5bar and flow rate of less than 20 litres per minute. The indirect heat exchange surfaces
are designed to provide a rapid heat up time. The unit comes complete with all the necessary safety
equipment to comply with legislation governing the installation of such systems.
1.1
Cylinder Suitability:
The SCX Solar cylinder should only be used as part of a solar installation and configured as shown in
figure 1.2. Additional safety devices may be required if the cylinder is operated with other heat sources.

2.1 Heat-up & Reheat Times*
*Heat-up and reheat times are for a guide only and are based on a primary flow temperature of 60oC
and heating water from 15oC to 60oC. The immersion of the cylinder or external boiler must be used
to raise the temperature to 60oC from the maximum temperature achieved at any time by the solar
system,.
Reheat times are those to heat 70% of the cylinder from cold.
