GENERAL DESCRIPTION AND INTRODUCTIONSECTION 1
GENERAL
INFORMATION
THE SOLAR SIDE
THE DHW SIDE
The SOLARflo systems have been designed and selected to offer a complete solar package
to provide Domestic Hot Water (DHW) with maximised contribution from solar irradiation for
commercial systems.
The systems offer solutions for a variety of applications, to deal with the larger applications
a
ssociated with commercial systems as well as dealing with higher storage temperatures and
legionella.
The systems break down into equipment sub-sections:
The Solar Collectors.
A Controller to control the solar gain and integrate the ètop upê heating.
Solar pumping system
Solar pipe-work ancillary equipment including expansion system.
The DHW generation and storage system
Destratification/anti-legionella pumping system
DHW expansion system
Cold water feed equipment
Primary heating system
DHW top up system (Pre-heat system only)
Various systems can be designed to best suit operation of the package. The system will
then determine what equipment is required. The type of equipment will then determine the
operation and installation requirements.
Andrews Water Heaters, offer a standard simple system based on single solar field, single
vessel (see Fig 3). However alternative systems are available to best suit the application.
EQUIPMENT SELECTION:EQUIPMENT SELECTION:
The equipment selection can be based upon duty and operation.
Andrews Water Heaters offer a set of standard packages to cover a large percentage of
requirements based on a simple solar thermal system.
SEE TABLE OPPOSITE FOR A GENERAL INDICATION OF EQUIPMENT DESCRIPTION
AND SELECTION POSSIBILITIES. THE TABLE ALSO SHOWS THE SCOPE OF STANDARD
SYSTEMS ONLY.
The packages are split into pre-heat system with a single coil unit and combined system
with a secondary coil.

Alternative systems are available and are discussed in the operation section of this manual.
Any specific information will be supplied with the package.
Other systems available on the SOLARflo systems include, multi-vessel, multi-solar field,
plate heat exchanger systems, dump valves.
