Solar Boilers - Have the Sun Pay Your Energy Bill
Residential hot water is a significant energy consumer for most homes. In actuality, hot water is occasionally the largest single energy price. Using solar energy to supply at least a few of the hot water in your home could lead to significant savings.
There are numerous ways that solar energy could be incorporated into a hot water system. Although solar boilers may be used independently, they are most frequently utilized along with traditional water heaters that are powered by gasoline or electricity. In this sort of system, the water heated with solar energy may be used on its own (if it's hot enough) or as preheated water to the standard water heater. Pre heated water will also dramatically reduce your energy bill.
Solar boilers may be utilised in any kind of climate but are most practical in areas that don't have freezing weather during the wintertime. Solar hot water systems in colder climates can use indirect heating systems that do not expose the water to the freezing temperatures. Rather, a fluid that resists freezing circulates throughout the solar panels and can be used to heat the water. Southern climates can utilize direct heating systems where the water itself passes through the solar panels installed on the roof.
There are two main kinds of solar hot water systems -- both active and passive. Passive systems rely on gravity and the natural flow of water from warm to cold. They are easy systems and need very little maintenance. They're durable and long-lasting. You can easely build simple systems all you will need are components which you may find in almost any hardware store.
Active systems use pumps to circulate the water. In certain systems, the pumps can be powered with solar energy; otherwise they need to be connected to the household electrical supply. In both systems a storage tank is required to maintain the heated water.
On hot days with loads of direct sun solar systems can heat water with surprising efficiency. During this sort of weather, there could be no requirement to use gas or electricity as a backup.
When the weather is colder, the solar heaters can preheat the water that passes into the standard water heater. This preheated water requires much less energy to deliver to proper temperatures that may cause significant savings on your electricity bills.
Like all alternative energy systems there's a good deal of room for your imagination if you like this. If you do not you do not and just use the technologies, but for people who like to have fun with technologies like myself these systems provide a plethora of possibilities to consider.
By way of instance, a stirling engine converts changes in temperature into mechanical movement, for example to create electricity. Mmm, that's a wonderful thought. A change in temperature is something this system provides, but additionally, it will heat your water. A double benefit?
