Storage tanks ( puffer )
Hot water storage tanks - PUFFERS
Hot water storage tanks are composed out of two circuits, the primary circuit and the secondary one.
The primary circuit makes the connection from the storage tank and the hot water boiler. The hot water from this boiler, through the flow pipe, enters the storage tank through the hot water inlet (3) in its upper part, and the accumulated cold water, in the lower part of the tank, is evacuated through the cold water outlet (6) and through the return pipe, it goes to the boiler.
The secondary circuit is made out of the heated water circuit, destined for consumption. The warm water from the tank flows through the cold water outlet (9) powers the consumers with heat. After the heat is released, the cold water returns to the tank and goes through the cold water outlet (8) on the lower part of the tank.
In the tank functioning, we can distinguish two stages. IN the heating stage, the boiler is functioning and gives the tank a certain quantity, more than the consumer uses, is released. This increases the water's temperature in the tank to a default value. Thermometers, respectively thermostats mounted to the connections (2) and (5) sense, respectively command the shut down process of the boiler.
The next stage is characterized through the heat supply to customers only due to the accumulated heat in the tank. After the heat transfer, the temperature from the tank slowly decreases moment where the boiler retakes it's heating function. This enables the optimization of the functioning boiler. The connection (4) serves to introduce and additional electric resistance for additional heating.
Through the drainage connection (7) the water can be completely evacuated from the tank for maintenance and repair.
The connection (1) serves to vent the tank to mount the safety valve.

Field of use
The storage tanks (puffers) are equipment for storing thermal agent for the heating systems and they are used in central heating systems. These store thermal energy provided by the boilers on gaseous or liquid fuel and optimize the burners functionality, respectively the operating regime of boilers on solid fuel.
By using a storage tank, the boiler can function for a longer period of time close to the rated load, at it's full efficiency, regardless of the variation of the thermal load to the customer, using the following advantages:
- fuel consumption decreases with 20 - 30%
- the lifetime of the heating systems components (boiler, chimneys etc.) increases significantly;
- the burning characteristics being optimal, the NOx emissions are diminished
- lowering the deposits in the boier
- the solid fuel boiler has to be recharged less frequently, a single load of fuel can provide the need for thermal heat on a period of one - two days.
The maximum flexibility in using the thermal agent (stored in the storage tank) both in the radiators, but also in the floor heating, domestic hot water preparation or other technological needs. The water from within the tank flows through a closed system, as such, does not corrode the interior of the tank, making it possible the usage of carbon steel, customary for its construction, without protective film on the interior surface.
The thermal insulation coating of the tank ensures minimal heat loss.
Each tank has a 6/4" connection to which, if required, any additional electrical resistance can be fitted at any time.
Depending on the created situation or the customer's preferences, one of the available heating alternatives (natural gas boiler or wood powered boiler and electrical resistance) or combinations between these.
