One time while I was looking for some tiles and decorative blocks at Citi Hardware (along J. Catolico Avenue), I came across a very fascinating equipment. I had no idea that this is available in our locality. I saw this thing in several photos and even use them in my lectures. So what am I referring to? It is a solar water heater.
A solar water heater is composed of water tank coupled with evacuated tubes. It relies on warm water rising, a phenomenon known as natural convection, to circulate water through the collectors and to the tank. In this type of installation, the tank must be located above the collector. As water in the collector heats, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the collector, thus causing circulation throughout the system.
The brand I saw is the SUNTEC SOLAR. Accordingly, the technology brings high efficient heating method adopting the advanced three target vacuum tube technology. Here are more interesting facts about SUNTEC solar water heaters:
- Did you know that 30% of the heat absorbed by a normal metal pipe system is lost even during day time ? But SUNTEC SOLAR absorbed the maximum amount of heat and the heat loss is very less due to the vacuum technology.
- What about hot water on cloudy days? No worries! Unlike other solar heating systems, SUNTEC SOLAR hot water system heat up with ultra violet rays (UV rays) even on cloudy days.
- SUNTEC SOLAR hot water system has no contact with Copper or any foreign metals unlike other water heating panels. It is 100% safe to drink.
- Now available tank capacity in 100L, 150 L, 200 L and 250 L.
It is truly wonderful that solar heaters exist in the city. Being in the tropics which significantly receive abundant solar energy, General Santos City can make great use of such technology and of such natural resource.
