With water heating accounting for some 25% of an average household’s energy usage, it makes sense to consider the alternatives to the conventional electric storage water heater, which are not especially energy efficient. Solar water heaters are a simple concept that work on the principle of radiant solar heat transferring to an exposed roof mounted panel. They therefore reduce your reliance on electricity as the radiant energy of the sun provides the primary heat source. Besides reducing costs you can also cut down on the greenhouse gases emitted by your household, which can help to minimise your carbon footprint.
There are two primary types of solar hot water systems, both of which work on very similar principles, though with slightly different configurations:
Most solar systems have an electric or gas booster system which ensures that you will have access to hot water on overcast days or at night – with a temperature regulated sensor that activates when a set temperature is reached.
So why should you consider solar hot water for your home?
