2. CONTRUCTION AND FUNCTIONING
Buffer storage tanks consist of a steel tank, foamed polystyrene insulation and
plastic casing and cover. The tank and the heat exchanger are made of St37-2 steel.
The inner surface of the tank has no
protection against corrosion; therefore it can
only be filled with heating water! Not suitable
for storing drinking water.
Storage tanks are insulated with max. 110 mm thick foamed polystyrene (with
graphite), and their casing is made of plastic. Casing and insulation can be installed
above 300 litres of capacity, so the tank can be set to its place of operation
irrespective of these. Without insulation, a tank with a capacity of up to 1000 litres
can be carried in through an 800 mm door. Combined buffer tanks also provide
domestic hot water (DHW) by heating cold water through the wall of a flexible
stainless pipe in a flow-through system. In combination with an indirect tank, buffer
storage tanks can supply hot water, either directly from the heat generator or with
energy obtained from the buffer storage tank. The polystyrene foam surrounding
the inner tank ensures that water stays warm for a long time, without consuming
energy.
Storage tanks are marketed in vertical design with a capacity of (PT) 500 (CF.2), (PT)
750 (CF.2) and (PT) 1000 (CF.2) litres. Tanks contain a Rp6/4” studs for connecting
the heat generators and heat emitters, and the flattened pocket tubes (pc=Ø11
mm, L=100 mm) located on the tank casing allow the installation of temperature
sensors. For the direct connection of solar or heat pump systems they include two
heat exchangers and a flexible stainless steel pipe coil to produce domestic hot
water.
3. INSTALLATION AND COMMISSIONING
For the installation of buffer storage tanks, the following conditions must be met:
• Make sure that the floor is intact and stable to support the weight of the fully
filled buffer storage tank.
• Horizontal and smooth floor must be ensured for the installation, so that the
appliance is vertical. If necessary, vertical position must be ensured by an
appropriate support for the bottom rings.
• The storage tank must be installed in a place protected from frost. If there is a
risk of frost, the tank must be emptied.
• The device must be installed so that its distance from the wall is at least 50 mm.
• To allow for later system expansions, a distance of at least 70 cm must be left
between the 6/4” studs and the wall or other architectural structural elements.
• Appropriate water supply and sewerage network (floor drain) must be available,
