Solar Water heaters Florida are often called solar domestic hot water systems. This is a cost-effective method of generating hot water for your domestic needs. In addition, they may be used in any weather or climate! What fuel source do they rely upon? Sunshine-and it’s free!
Types of Solar Water Heating Systems
In a solar water system, there is a solar collector and a storage tank. This forms one of two types of systems: an active one with controls and circulating pumps or a passive form.
There are two types of active solar water heaters:
Direct Circulation Systems: The pumps circulate water via the collectors into the house. They operate in just about any climate where freezing is not a concern.
Indirect Circulation Systems: The pumps circulate a heat-transfer fluid via the collectors and the heat exchanger. The water heats up and flows into the house. This type of system is commonly used in areas with freezing temperatures.
This type of system is less expensive than an active one but not as efficient. They are however more reliable and durable. The two types of passive system solar water heaters are:
Integral collector storage: These are best used in areas that do not experience below-freezing temperatures as well as in homes that have significant day and evening hot water requirements.
Thermosyphon systems: Water begins to flow when the warm water rises and the cold water sinks. The collector is installed below the tank enabling warm water to rise into it. Although these systems are very reliable, attention must be paid during installation and particularly to the roof design as these tanks are quite heavy. Thermosyphon systems are also more expensive than integral collectors.
Types of Storage Tanks and Solar Collectors
Solar water heaters require an insulated storage tank, an inlet and an outlet which connects to and away from the collector. In a two-tank system, the water is preheated by the solar water heater before entering the conventional heater. In a one-tank system, a backup heater is placed within the solar storage.
In residential applications, three types of solar collectors are utilized:
Flat Plate Collector: These are glazed, insulated and weatherproofed boxes which contain an absorber plate under a glass/plastic cover.
Integral Collector Storage: Also called batch systems feature one or more black tubes or tanks in a glazed box. The cold water will pass through the solar collector which will preheat the water. Then it continues to the backup water heater for a reliable hot water source. These may only be installed in mild freezing climates because the outdoor pipes may freeze in harsh cold conditions.
Evacuated Tube Solar Collectors: These feature parallel rows of glass tubes. Within each tube is a metal absorber tube which is attached to a fin. The coating on the fin absorbs solar energy and inhibits heat loss. This type of collector is often used in commercial applications.
Before purchasing any type of solar water heaters Florida, it pays to heed to study and understand the different types of systems out there. Getting in touch with a solar energy company like PS Solar Systems can greatly help in this matter
