1.7 Specific operating instructions
The addition of chemical substances to the heating water may impair the function of the regulator. Therefore, do not add additio-
nal chemicals to the system during operation. Please pay attention to information on the filling water quality on the following
pages of the user manual. Do not use treated soft water as filling water in combination with a magnetic
®
Heating Water Regulator.
This can result in malfunction or a strongly increased pH value. In case of high total hardness or electrical conductivity of drinking
water >200 μS/cm, the filling water should always be treated by means of water demineralisation using an ion exchanger.
Check if aluminium alloy is present in the system and whether this poses a limitation on the maximum pH value. When using a
Heating Water Regulator, the pH value may increase to >9.
1.8 Conformity declaration
Regulators from magnetic
®
are pressurised containers which are subject to the scope of the Pressure Equipment Directive 97/23/
EC Section 3, paragraph 3. CE labelling will not be granted. Magnetic regulators are constructed and manufactured according to
good engineering practice. A leakage and original pressure inspection is carried out.
2. Layout of the electrochemical water treatment
2.1 Layout of the Heating Water Regulator
The magnetic
®
Heating Water Regulator 50 plus is suitable for use with systems with a volume of up to 15 m³.
The magnetic
®
Heating Water Regulator 100 plus is suitable for use with systems with a volume of up to 35 m³.
2.2 Estimating the system volume
In heating systems, the system volume is often unknown. The system volume can be estimated by means of the heating capacity.
For today’s heating systems, an average <20 litre contents per kW heating capacity without a buffer tank is assumed.
Based on experience, for floor heating a content of <18.5 l/kW, applies for radiators <12 l/kW and for panel radiators <8.5 l/kW all
incl. risers and content of heat generators.
For systems with older parts, please pay attention to the fact that today’s heat generators heat the same water quantity with
significantly less input. You should take 15-20% into account in the layout.
2.3 Water content of buffer tanks
Among other things, the size of the HWR is determined by the assumed oxygen intake in the entire network, in particular at screw
fittings, plastic lines, control units, etc. The volume of a steel storage tank is not taken into account, as hardly any oxygen diffusi-
on takes place here.
