Flushing and Charging Heater-Side 
 
 
 
Charging Valves, Heating Water Quality 

Required equipment heater-
side 

In the compact heat pumps,  
AQUATOP T..C.. , the charging valve,  
manometer, safety valve, expansion  
vessel and circulating pump are all  
integrated (see illustrations on Page 
31). The standard model heat pumps,  
AQUATOP T..H.. , have to have all 
this equipment installed on site! 
 

 
Flushing, Charging and Venting 

 
The heater side also has to be 
flushed and charged. The charging 
water of the heating system has to be 
treated in accordance with the VDI 
2035 requirements. Complete venting 
of the heating system is important, 
since otherwise the heat pump will 
not function properly. Consequently, a 

vent has to be provided; the compact 

heat pumps already have a vent inte-
grated in the flow line. 
The primary pressure in the mem-
brane expansion vessel (heater, fac-
tory setting 1 bar) must be adapted to 
the conditions on-site. (Static height: 
1 m = 0.1bar 
The cold charging pressure should 
comply with the following. Primary 
pressure MEV + 0.2 bar (water seal) 
 

   

Charging must comply with  
DIN EN 1717. 
 

   

Attention: Check water quality, 
VDI 2035 

Heating water quality 

The composition and quality of the  
water in the system has a direct effect  
on the performance of the entire  
system and the lifetime of the heat  
pump. For the initial charging and  
backfill of the system, usually normal  
tap water with a pH value of 7-8 can  
be used as long as the water is not  
highly corrosive (chloride content  

> 150 mg/l) or hard (>14°dH; degree 

 

of hardness IV). A drinking water  
analysis can be requested from the  
local water supply company. If the  
specific system volume is greater 
than 25 liters/kW heating output  
(e.g. through the installation of a hot  
water buffer storage), then the maxi- 
mum permissible calcium carbonate  
input from the charging and backfilling  
water should be calculated in  
accordance with the VDI guideline  
2035. In some cases the charging  
water has to be softened. The use of  
chemical anti-corrosion agents is not  
permitted. 
 
In Austria the ÖNORM H 5195-1  
applies as well. 
 
In Switzerland the following applies  
as well: SWKI Nr. 97-1 

Unknown water quality and re-
placement systems 

Often heating water contains sub-
stances and additives which affect  
the functioning and lifetime of the 
heat pump. 
Therefore, either 

• 

heat up the old system and  

 

completely drain before replacing  

 

the system  

 

or 

• 

flush carefully after replacing the  

 

heating system. Ideally the  

 

system should be flushed imme-

 

diately after being heated up the 

 

first time.
