SOLAR WATER HEATING SYSTEMS
There are number of systems which can be used to heat your water. The great advantage of having a Solar Water heater is that ITS FREE! Decision what type of the system is right for you depending on your location and the quality of the water available. Versol designs bespoke systems and can advise and help you to choose the correct system for your premises.There are several different type of Solar Heating Systems available:
• Thermo Siphon Systems
• Split System- Forced Solar Water Heating System
• Split System- Drain Back Solar Water Heating System
SOLAR WATER HEATERS- THERMO SIPHON SYSTEMS
Thermo Siphon is the cheapest system available and is normally used to describe a Solar hot water system where the water tank and Solar panel are located together and installed ideally on the roof of the building although they can be installed in almost any location. This type of system is suitable in projects where the consumption rate is low, especially for Villas or small offices.
SPLIT SYSTEM- DRAIN BACK SOLAR WATER HEATING SYSTEM
Drain Back System is another type of indirect system that use pumps to circulate water through the collectors but the system is “open” type. The water in the collector loop drains into a reservoir tank when the pumps stop. This makes drain back systems a good choice in colder climates and also for installation where there is a risk of overheating. Drainback systems must be carefully design and installed to assure that the whole system is always completely drain down to the tank when there is no need for heating.
SPLIT SYSTEM- FORCED SOLAR WATER HEATING SYSTEM
In Split System Solar the Panel is placed on the roof and the actual water tank can be placed anywhere inside or outside the building. These systems are slightly more complicated and require a number of components such as circulation pumps, control valves, controllers etc… Our systems come complete with electronic controller, electrical backup and circulation pump.The Circulation pumpscirculate heat-transfer fluid such as anti-freeze liquid, through collector or bank of collectors and then through the heat exchnagers which are inbuilt or external to the storage tank. Heat exchangers transfer the heat from the fluid to the potable water stored in the tanks. Some indirect systems have overheat protection, which protects the collector and the glycol fluid from becoming super-heated when the load is low and the intensity of incoming solar radiation is high.
