Solar energy has long been used by man to heat water. At its most primitive, this was done by simply putting water in a pot and leaving it in the sun. This basic concept is known as solar thermal water heating. As you might imagine, modern systems are a tad more sophisticated, but some can still be damaged by freezing problems.
There are three big expenses when it comes to powering your home. Basic electrical needs for your lights, computers, televisions and such is one. Heating or cooling the home is the second. Heating the potable water you use is the third and can constitute a third of your utility bill. Solar thermal water heating is one way to combat the water heating expense.
Heating water takes a lot of energy. Fortunately, there is plenty of it in sunlight. If you don’t believe me, just consider your car. What happens if you leave it in a parking lot on a sunny summer day? The interior heats up to the point that you can barely sit down or touch anything. This is a form of passive solar energy where heat is the end result.
Many emergency plumber brisbane work on the same concept. The water is heated either by sitting in a container exposed to the sun or by being run by a heating element powered by the sun. These systems go by the names “Active Direct System” and “ICS”, which stands for integrated collector storage. Whatever the name, the systems work very long as the weather is warm. Problems, however, can pop up when the weather drops below the freezing point for water. When this happens, the transporting pipes and flush systems can freeze and bring the system to a halt. Frozen water can also pop or disfigure seals and the system can fail.
You can still use solar thermal to heat your water if you live in an area that gets freezing temperatures. You simply have to go with a system that can handle them. There are systems that run on a different solar thermal process. Instead of heating the water directly with the sun, the systems run a second set of pipes that are filled with a non-freezing liquid. This liquid warms up and then runs along an interface with the potable water where it transfers its heat and keeps the water from freezing. Glycol and Drain Back systems are the two most common that use this approach and will work in nearly every cold climate.
Solar water heaters using the thermal heating approach can slash your utility bill by 30 percent or more each year. That won’t mean much, however, if your system is damaged by freezing so make absolutely sure that you have a system that can handle the year around temperatures you live in.
