Page 4: Solar Energy Explained
Just some of the benefits of a solar water heating system: • Savings - A Firebird solar heating system can cut your heating bills by up to 90% in the summer and up to 30% in the winter, on average this equates to approximately 50-70% reduction in your hot water heating costs annually. - Page 5 (sunlight) is available at ground level and can be converted into useful heat by your Firebird solar collector. During the summer months the Firebird solar heating system could provide the total energy needs for heating all your water.

2. Set the solar fraction of the total DHW energy. CVSKC-10, TZ58-1800, CPK7210-N 3. Calculate the required energy to be collected by the solar. 4. Choose which Firebird solar system is to be used. Calculate the hot water demand 5. Calculate the storage volume required and hence the total required volume. - Page 15 SOLAR SYSTEM DESIGN Calculate the Daily Hot Water Demand Typical hot water demand for a domestic household is within the range of 30 litres to 70 litres per person per day. This value is dependant on the demand of water i.e. a dwelling that uses large volumes of hot water (baths) on a regular basis would have a higher demand than those who do not.

Page 19: Stagnation
As a result the solar energy reaching the panels, continues to heat the fluid in the panel, causing it to evaporate within the panel. This is referred to as stagnation. The Firebird solar fluid is designed to cope with stagnation temperatures of up to 200˚C. However, repeated and frequent stagnation will cause the glycol to disintegrate, thereby losing its frost protection and its recommended ph value, causing a scale build up or corrosion in the pipes. -
Page 20: Safeguard Against Legionella
The Firebird differential controller has an anti-Legionella function built in. This function must be connected to a Second Relay (R2) to enable it to operate, by means of motorised value or immersion. The function enables the controller to record temperatures over a set period of time (e.g. -

Page 27: Installation
Before commencing any site work, determine the best roof location for the solar collectors and decide where the tank and other large components are to be located. When installing a Firebird solar system, we would suggest the following order of installation, although not mandatory: •... - Page 28 • Never lift the collectors by the connections or the screw threads. • A special kit is available for carrying and lifting flat plate collectors (please contact the Firebird sales office for more details). • Do not expose the collectors to direct sunlight until the installation is complete. Firebird provide special weather proof covers if the panels are going to be left exposed for a long period before commissioning.
- Page 29 Connecting solar collectors in series All Firebird Solar collectors can be joined in series. The CPK7210-N Flat Panel Collector and the CVSKC-10 Vacuum Tube Collector, have male and female connectors at each end to facilitate interconnection. A special gasket is provided to seal the connection between each collector.

Page 38: Commissioning
COMMISSIONING 10.0 COMMISSIONING NOTE: The solar system should be filled and commissioned as soon as possible after installation to avoid any unnecessary heat build up in the collectors. If there is a delay with the commissioning of the solar system, the collectors must be covered with a suitable weather and UV-proof cover. 10.1 Filling the Solar Circuit WARNING: filling the solar system should only be carried out in low light with the... -
Page 39: Maintenance And Service
To ensure the optimum transfer of solar energy from the collectors to the storage tank, the correct flow rate for the solar circuit needs to be used. Firebird recommends a flow rate of between 0.5 to 1.5 l/min per m2 of aperture. -
