SHORT DESCRIPTION OF THE SYSTEM
Solar Heat Exchangers successfully tendered for the supply and installation of a 2,000L solar hot water system for the Northcliff Eye Clinic in Northcliff, Gauteng.

Solar Heat Exchangers is a wholly owned subsidiary of Solsquare, a company established in 2007 specialising in Solar Photovoltaic system design and installations.
CHARACTERISTIC’S OF THE SYSTEM
The hot water system was designed against a client brief by Wawi Consulting with a 2,000L hot water storage capacity.
PLANT ROOM FOR STORAGE VESSEL
The plant room houses 2 x 1,000L insulated hot water storage tanks in series. These solar storage tanks are heated by an array of 15 x 2sqm solar collectors. The tanks include electrical backup elements in case of no or low solar contribution.
The plant room is positioned on the roof of the building with the solar collectors.
FRAMES FOR THE PANEL INSTALLATION
The collectors are mounted on flat roof mounting fames facing north. The 15 solar collectors are mounted in 2 rows and are plumbed in 3 banks of 5 collectors. Concrete lintels were laid down as a base for the frame mounting to ensure integrity of the roof’s water proofing membrane. The frames were mounted onto the concrete structures that were separate from the roof’s water proofing membrane.
MAINTENANCE & INSTALLATION CHALLENGES
Solar Heat Exchangers calls for a new Service Level Agreement annually with the client to look after the maintenance of the system. One of the bigger challenges was access to the roof. A 6 ton crane had to lift all the equipment, tanks and components onto the roof. Safety was one of the primary concerns and staff operations were closely monitored.
