Buffer storage tank for heating water & solar systems
Buffer storage tanks by the manufacturer ratiotherm serve as caches for currently unused energy from different heat sources such as boilers, heat pumps, cogeneration units, solar plants or other renewable sources.
Today, these domestic hot water buffers are integrated almost as a standard feature in every heater; they boost the efficiency of older systems as well. Because by compensating for temperature fluctuations between production and consumption, they ensure that the heating system does not have to reactivate immediately with every heat request.
This avoids the constant, particularly consumption-intensive On and Off, with clear improvement in the heater’s exhaust gas values, efficiency and service life.
The storage systems are mainly used for temporary storage of energy in the areas of solar systems, water heaters, shower water and drinking water.
Modern heat storage tanks for use in buffering by the manufacturer have several connections, so that they can be operated in parallel with solid fuel boilers, heat pumps, solar systems or other sources of heat supply. Various factors need to be taken into account when choosing the size of the storage tank: the number of house residents and their personal needs as well as the overall energy concept of a building. As a rule, a stratified storage tank has a size of 750 to 1000 litres, depending on the requirements of the heating system. However, it should be noted that heating and drinking water must not be mixed. That is why, with particularly efficient heat accumulators, a fresh-water station is a must, and not just for hygienic reasons. This prevents the very occurrence of the danger that e.g. bacteria such as Legionella can develop as might occur with a combination ‘tank-in-tank’ in which warm drinking water is standing and not moving.
Buffer storage tank for solar systems
Efficient buffer storage tanks for solar systems with solar collectors are optimally suited to be able to use energy generated on sunny days, even in the evening and at night or in longer periods of cloudy weather. In addition to the combination storage tank, there are other common types. The fresh water bufferworks in much the same way a continuous-flow heater. Here the drinking water moves in pipes through the hot heating water and is heated only on call. However, the storage tank for solar systems may be mixed considerably. The most modern, intelligent and efficient variant is the stratified storage tank, which works based on the natural principle of stratification of cold and warm water. Here, too, flowing drinking water is freshly heated on demand, eliminating fears of bacteria formation. For a perfect match of the individual components, it is advisable to purchase a system with solar power and a storage tank, preferably with the entire, hence coordinated, heating system from a single manufacturer.

What is a buffer storage tank?
These storage tanks involve the temporary storage of heating water in heating systems. The purpose of these storage tanks is to create a balance between the heat produced and already consumed. They can thus be used in addition to heat sources such as heat pumps as a way of generating a greater energy efficiency. Specialised companies produce systems of this type for use in efficient heating systems. The heat buffers are used in solar thermal systems, for instance.
