Thermos Bottle Technology allows for Solar Hot Water in Cold Climates
Solar-heated hot water systems have long been available in those areas where sunny days and warm temperatures are routine instead of rare. However, those shivering in colder climes can now take heart. The Solar Panels Plus company has introduced the SPP-30, a solar hot water heater designed to work efficiently in cloudy and cold conditions.
In February, 2010, Solar Panels Plus installed five SPP-30 solar energy collectors at The Homestead Family Restaurant in decidedly chilly Blackfoot, Idaho. Each collector contains 30 double-walled glass tubes featuring a unique optical coating that helps the collectors hold and concentrate heat.
If the basic technology sounds vaguely familiar, it is. The SPP-30 expands upon the basic laws of physics and heat transfer that Thermos bottles use so successfully. The technology has limits, though. As efficient as the SPP-30 system is, it is still recommended as a support and not a replacement for conventional heating systems in cold climates. For those living in areas where cross-country skiing is a summer sport – help is coming, but don’t give up that traditional furnace just yet.
