8.5.1.3 System design
Solar thermal hot water systems shall be designed to ensure satisfactory performance. Issues to be taken into account include:
- location
- system
- compatibility
- performance.
8.5.1.3.1 Location
Solar thermal hot water systems should be correctly located.
Solar thermal collectors, including ancillary components, should be located and identified in accordance with the manufacturer’s recommendations.
Solar thermal hot water, when sited in coastal locations, should be suitable for the environment. Manufacturers, recommendations should be followed detailing requirements.
8.5.1.3.2 System
Solar thermal hot water systems should be designed in accordance with the manufacturer’s recommendations, certification
scheme requirements and appropriate standards.
Each system should generally be supplied from one manufacturer as a package, not as individual components or materials. However, where components from more than one manufacturer are used, they should be compatible to ensure satisfactory performance.
Solar thermal systems should be designed to prevent stagnation and damage to the collectors from oversizing.
8.5.1.3.3 Compatibility
Solar thermal hot water systems should be installed so as not to adversely affect the performance of the building to which they are fixed, and in accordance with the manufacturer’s recommendations.
Multiple systems should be compatible with each other.
8.5.1.3.4 Performance
Solar thermal hot water systems designed to contribute towards space and water heating should be designed in accordance with the performance requirements in Chapter 8.3 Space heating systems and Clause 8.1.8.
