The most common application of Solar Heating are systems designed to heat the domestic hot water. A inner part of such systems it the hot stellar water tank, worn to lay up the solar thermal force. An Heat Exchanger tranfers the warmth bent in the Collector to the drinkable water in the well-insulated tank, where it can be cling to for hours or irregularly time until it's consumed for example providing a bath or shower. Typical character of a solar hot water tank compared to conventional boilers or hot water tanks are: - For an household of a given size the volume – and so the storage capacity – of a solar storage tank is considerably high. - The shape of a solar tank must be skinny and high, so it can have support for he thermal stratification that happens in the tank: the apparatus that exchanges solar heat at the bottom of the tank works with cold water; the hot water then rises to the top of the tank. - The hottest water is at the top of the tank, and the outlet is there for that reason. A very well-built lagging prevent heat loss and facilitates heat straying for not only hours, but days. - At least two heat exchanging units: the first at the bottom of the tank to transfer the solar heat to the tank, the second in the upper part of tank to allow additional heating by another source that is activated when the water in this part of the tank falls below a minimum temperature setting. Therefore, hot water is never unavailable. Generally a solar hot water tank will be dimensioned to about the double size of the anticipated amount of consumption per day. Concerning this, the container for a family with 4 people and a standard spending of 40 litres hot water per head and day should seize about 300 to 320 litres. Use Solar Combisystems to prevent hygenic problems in bigger households that have a higher vacillating total consumption per day. Properly done the insulating of a solar hot water tank can help a lot to system work efficent. There is more information about how to do this on http://www.yoursolarwaterheater.com.
