Home Central Heating

From an energy efficiency angle a lot of heat goes to waste if only one room needs heating as central heating systems may heat unoccupied rooms.  In buildings with isolated heating it can often work out more cost effective to not use central systems and instead use individual room heaters and fireplaces.  Architects are also now designing low energy buildings with energy efficient windows, more insulation, and heat recovery ventilation.  Hot water recycling is also possible which recovers the heat from dishwashers and showers.

Most existing conventional central heating systems can be used with solar panelling to take advantage of renewable and sustainable energy.  The principal of solar heating is straightforward.  When the sun shines, water is driven through the solar panels and is then heated by solar energy.  This heated water then warms the water already in the hot water cylinder as it flows through a heat exchanger.  The water can then be used as required.
