Renewable Energy Heating Systems
Traditional fossil fuels are fast becoming exhausted. World prices for oil and gas
are at an all time high and are unlikely to fall in the foreseeable future.
It is internationally recognised that burning fossil fuels damages the environment
and governments are now committed to reducing our dependancy on carbon based fuels.

Energy provided by the sun is limitless, free and renewable. This energy is stored in the ground or in the air in the form of heat, no matter what the ground or air temperatures are currently reading. Major climatic changes (global warming) will not affect this phenomenon.
