How much space do I need?
20 Mar 2013

This depends on the size of the solar water heater system you require. A family of 4 would need a boiler of at least a 200-litre capacity and a panel area of about 4m². This might change depending on your latitude (the further away from tropical latitudes you are, the larger surface area you will need). On average a solar water heating system uses around 4m² of roof space.
