Using filling water and top-up water which does not meet the stated
quality requirements can cause a considerably reduced service life
of the equipment. The responsibility for this lies solely with the
operator.
1.2.6

Heating and sanitary side connection

▪ Create a heating system according to the safety requirements of
EN 12828.
▪ With sanitary connection, you must observe
▪ EN 1717 – Protection against pollution of potable water
installations and general requirements of devices to prevent
pollution by backflow.
▪ EN 806 – Specifications for installations inside buildings
conveying water for human consumption.
▪ and, in addition, the country-specific legal regulations.
INFORMATION
The domestic water quality must comply with the
EU Guideline 98/83 EC and the regionally-applicable
regulations.
The connection of a solar installation, an electric heating rod or an
alternative heat generator may cause the storage temperature to
exceed 60°C.
▪ For this reason you should fit scalding protection (e.g. VTA32 +
Screw connection 1")
▪ Use a pressure reducer if the cold water connection pressure
>6 bar.
If the hot water storage tank is connected to a heating system with
steel pipes, radiators or non-diffusion-proof floor heating pipes, slurry
and swarf could enter the hot water storage tank and cause
blockages, local overheating or corrosion.
▪ To prevent possible damage, fit a dirt filter or sludge separator into
the heating return flow of the system.
▪ SAS 1
INFORMATION
To avoid heat losses caused by gravitational circulation,
circulation brakes SKB shall be installed into the
connections.
