BuildItSolar: Solar energy projects for Do It Yourselfers to save money and reduce pollution. Bimble Solar. Solar. A solar water heater uses energy from the sun to heat water for your home. If a solar water heater is right for you, it can save you energy, save you money and reduce your greenhouse gas emissions. A solar water heater is an effective way to make use of Australia's abundant sunshine. Depending on your location, the direction your solar panels face and the amount of water you use, a solar water heater can provide between 50 and 90 per cent of your hot water needs. You can choose between a gas or an electric boost to supplement your hot water when required. How solar water heaters work Solar panels on your roof collect the sun's rays and heat the water, which then flows to a storage tank, ready for use.
In a thermosiphon system where the tank is mounted on the roof above the collectors, cold water flows naturally into the collector because it is heavier than hot water. The solar collector is made of materials that absorb heat from the sun very efficiently. Types of solar water heaters. Heat Pumps. Heat pumps move heat from one place to another. Some can pump heat both out of and into a building, for cooling or heating. Air conditioners (or "chillers" for large-scale systems) are a kind of heat pump that can only pump heat out of a building, but can do it slightly more efficiently than bi-directional heat pumps. Small-scale heat pumps. Heat pumps are important for efficient HVAC systems because moving heat can use less energy than generating heat.
To think about moving heat rather than generating it, imagine a tanker truck driving fuel from one place to another--the truck may be hauling thousands of liters of fuel as cargo, but truck's own gas tank only holds a few dozen gallons, because that's all the fuel it needs to burn to carry the load to its destination. Heat pumps can move several units of heat energy per unit of electricity Measuring Efficiency There are many ways to measure the effectiveness of a heat pump: COP (coefficient of performance) is the simplest measurement.
