Heat Pump Booster Introduction • 1.1 What is a Solar Powered Hot Water ? – Some systems have the storage tank and the solar collector panels on the roof However, if you don't like the look of the storage tank on the roof or if your roof can't support the weight - you can choose a pumped system that has only the collector panels on the roof, while the tank is at ground level Introduction • 1.1 What is a Solar Powered Hot Water ? Introduction • 1.1 What is a Solar Powered Hot Water ? – A Solar Hot Water System requires only daylight to generate heat so can still generate hot water on a cloudy day There are three main components in a Solar Hot Water system for domestic applications: • Solar Panels – that collect heat from ambient daylight and transfer it to a solar fluid (a glycol/water solution) • Plumbing System – which includes simple piping and a pump, to pump the solar fluid around the system to heat the water • Hot Water Cylinder – which stores the hot water for domestic use Introduction • 1.1 What is a Solar Powered Hot Water ?

Instalation Tips: To get the most out of your solar hot water system, ensure that: • The roof's structural strength is assessed (by the installer) to ensure that it can support the weight of the system • The collectors are positioned facing north Typically they are mounted flush against the roof so their angle above horizontal is around 20 to 26 degrees Increasing this tilt angle will improve winter performance in Perth but may add to installation costs • The solar collectors are not excessively shaded by trees or nearby buildings, particularly when the sun is low in the sky during winter 196 How the Installation – Manual Operation ? Instalation Tips: To get the most out of your solar hot water system, ensure that: • storage tank and solar collectors are as close together as possible to reduce the length of the connecting pipes (in gravity feed and pumped systems) • All components, including pipes, are well insulated • The booster control is in an accessible location with an indicator light and a timer switch to optimise solar gain in cooler months 197 How the Installation – Manual Operation ? Instalation Tips: To get the most out of your solar hot water system, ensure that: • Frost-protection is included for areas where freezing conditions are possible • A thermostatic tempering valve is installed or included if you wish to avoid water being too hot during summer • The system is suitable for the water quality in your area • All plumbing and electrical work is done by a licensed contractor 198 How the Installation – Manual Operation ? Openrating Tips: The most effective way to obtain maximum performance from your solar hot water system is to make efficient use of hot water in your home • Do jobs requiring hot water in the morning where possible This allows the water remaining in the tank to be reheated by the sun and reduces expensive boosting • The recommended setting for the booster thermostat is 60°C Higher settings will increase the amount of energy used for boosting • For Perth, an appropriately sized solar hot water system will give plenty of hot water all summer without boosting - turn your booster off during this time of the year 199 How the Installation – Manual Operation ? Openrating Tips: The most effective way to obtain maximum performance from your solar hot water system is to make efficient use of hot water in your home • In autumn, spring and sunny winter days you can minimise running costs by only boosting for a limited period in late afternoon and evening, if the water has not reached the required temperature with solar energy • Conserve hot water by using it efficiently • Make sure you follow the manufacturer's recommendations for maintenance of your solar hot water system • If your system requires a sacrificial anode in the storage tank, ensure it is replaced at the appropriate intervals 200 References 201 Thanks you ! 202 ... a Solar Powered Hot Water ? 1.2 What you need to know about Solar Hot Water ? 1.3 What Solar Hot Water Systems are Compliant? 1.4 The history of Solar Powered Hot Water 1.5 How the used of Solar. ..
