   Central solar heating is a sub-class of 'large-scale solar heating' systems - a term applied to systems with solar collector areas greater than 500 m 2. Aquifers, boreholes and artificial ponds (costing €30/m 3 ) are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ...
