The solar collector System is capable of contributing significantly to space heating requirements in many areas. The best use for solar energy is to heat a building by radiant under floor hydraulic heating, which requires water at a temperature of around 60C. This system usually uses a concrete floor slab with special water pipes running through it, to provide a pleasant, even, low temperature radiant .The floor slab will also provide heat .
