Types of solar water heating panels
Evacuated Tubes –
Evacuated Tubes are made from glass – typically ultra-strong and heat resistant Pyrex with a double wall construction. The glass on the inner tube is coated on its outer surface with an absorbent coating, and on its inner surface with a reflective coating. Inside each tube all air is removed making a vacuum and a copper heat pipe is located through the centre of the tubes. Most of the infra-red radiation (i.e heat) from the sun is absorbed by this sealed heat pipe which contains an anti-freeze type liquid.
As heat rises, hot vapours from the antifreeze rise up to the top of the heat pipe where its copper tip connects with a header pipe through which more antifreeze flows. This hot antifreeze is then pumped through pipes inside the hot water tank with the end result that the water gets hotter and the antifreeze cooler. The antifreeze then continues its journey around the system and back out to the solar water heater to be reheated.
The copper at the tip of the heat tube can reach well over 200 degrees easily heating water to 90 degrees Celsius on hot days and to 60 degrees Celsius even in the winter. This simple system is completely sealed and needs minimal maintenance over its 20+ year’s life.
Flat Plate Collector –
Flat-plate collectors are the most common solar collectors for use in solar water-heating systems. A flat-plate collector consists basically of an insulated metal box with a glass or plastic cover (the glazing) and a dark-coloured absorber plate. Solar radiation is absorbed by the absorber plate and transferred to a fluid that circulates through the collector in tubes. In an air-based collector the circulating fluid is air, whereas in a liquid-based collector it is usually water.
The Benefits of Solar Water Heating
Hot water throughout the year: the system works all year round, though you’ll need to heat the water further with a boiler or immersion heater during the winter months.
Cut your bills: sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.
Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
