solar roof water heating system

Conserving energy has not only become what some might call a fad but it has also become a necessity. People not only need to conserve for the environment but also for the wallet. The cost of living has risen and keeps rising each year. Having efficient appliances and utilizing the sun and wind power can not only help save the environment but also cut living costs.

We've all heard of windmills and solar power, now you can use the solar power to not only power your light, heat your home and now heat your water too. A revolutionary system developed in England can now be found and used almost anywhere.

The Apricus roof system is a can heat 360 gallon tank of water using 60-70% of sunlight, where as the older photovoltaic only uses 13-15%.

The double walled, evacuated glass tubes are the key component behind the Apricus water system. The system works just as well in January as it does in July, picking up the slightest amounts of heat on the most overcast of days. The temperature inside the glass tubes can reach up to 250 degrees Celsius, them it is transpired to copper tubes acting like a wick transferring the heat to a secondary source. The glass system is remarkably strong and can with stand up to 1 inch hail.

The great thing about this system is that is will last for years, you may have to replace the propylene glycol that is used for the heat exchange, probably every 7-10 years. And apart from a circulating pump the system does not involve moving parts. Rainfall keeps the solar collectors clean.

All in all this is a great system and can be used for large dairy farm to your home or cottage. This solar collector can often be used with your existing hot water system. This system can also easily heat pools and spas, of course depending on the size you are trying to heat you may need a rather large system.

The operation of the solar collector is very simple.

2. Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.

3. Solar Energy Storage: Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10^oC / 9-18^oF. Throughout the day, the water in the storage tank is gradually heated.
