Thermal solar power is one of the most environmentally safe and cost effective sources of energy around today. This is one of the reasons the solar water heaters are becoming so popular among the environmental conscious people who can afford them.
One of the most important parts of a solar water heater system is the controller. The purpose of the solar water heater controller is to monitor the temperature of the system. To do this, it interacts with sensors and based on the reading tells the pumps to turn on or turn off.
Some of the more modern and expensive water heater controllers allow customers to access the system via the Internet. They can log on to a website and remotely turn the system on and off or adjust the temperature.
The monitoring system also sends data back to the distributor’s home office. This enables them to remotely troubleshoot problems for homeowners when something in the system goes awry. In many cases, this saves the company from having to send a maintenance engineer to the customers home to identify the problem.
But the monitoring system also allows the company to be proactive in resolving problems. Many times, there are signs of system troubles long before something breaks down in the water heater. This remote monitor functionality can periodically test the system components to identify any areas of potential problems.
Another advantage to the installers of these systems is that, over time, the amount of detail collected by these controllers allow them to set optimum price points for themselves. They can create billing models that very accurately allow them to predict future usage patterns. And, as a result, can offer prices that give their customers a good deal as well as provide them with a good amount of profit.
In simpler and cheaper systems, the water heater controller is simply a thermostat which switches your pump on or off depending on the temperature of the water and the temperature setting you have set on the thermostat.
