Värmebaronen EK 15E

General

Installation must take place according to existing 

rules and standards.

 

Heating systems can differ from one country to the 

next due to climate, traditions and national regulations. 

In cases where standards violate national regulations, 

the latter must be followed. National and individual 

requirements must be taken into account.

The electric flow heater must be located indoors 

in a suitable location equipped with a floor drain.

The electric flow heater is mounted horizontally 

so that the air that is released can circulate.

An system equipped with a closed expansion tank 

must undergo an installation inspection prior to 

first operation. The inspection must be carried out by 

a person who is qualified for the task. The boiler or 

expansion tank may not be replaced without another 

inspection.

Valves must be fitted between the flow heater and 

the heating system.

Cables and pipes must be laid so that it is possible 

to open the front and remove the roof plate for service. 

For installation and accessibility for service, there 

must be at least 60 cm space above and in front of 

the cartridge.

 

The electric flow heater is designed for non-

oxygenated water.

Water quality

Tap water is usually classified from the point of view 
of hygiene. Good water classified on this basis is not 
automatically suitable for a heating system. To avoid 
problems a technical water analysis should take place. 
Any nonconformities with standard values should be 
corrected.
If the volume of the heating system is low, the boiler and 

heating system may be filled with water that is not classified 

as good boiler water. When the water is heated, some 

oxygen and carbonic acid are emitted to the expansion tank 

or vent valves. The remainder will react with the metals in 
the system. This corrosion is often insignificant as the same 
volume of water circulates and it soon becomes oxygen-free. 
What is important is that the system is leak-proof so that 
the water is not replaced with new oxygen rich water and 
the water is not oxygenated during installation.
In large systems, it is impossible, in practice, to protect 
against leaks and oxygen admission. In such cases, 
an oxygen-consuming agent can be added so that there 
is always a slight surplus in the system. These agents 
often contain corrosion-limiting additives.

Suitable water line quality:

Alkalinity ≥ 60 mg / l to avoid corrosion.

 

Carbonic acid content > 25 mg / l increase the risk of 
corrosion.

 

Sulphate contents > 100 mg / l may accelerate corrosion. 

If the sulphate content is higher than the alkalinity, there 
is a risk of copper corrosion.

 

Hard water causes boiler scale and is not suitable in 

a heating system.

 

Very soft water may cause corrosion damage.
Chloride levels above 100 mg / l make the water aggressive, 
especially together with lime deposits.

 

Low pH values may cause corrosion damage. The pH value 
should be between 7.5 and 8.5.

 

The presence of carbonic acid in combination with low pH 
and hardness values makes the water aggressive.

Flow requirements

The electric flow heater requires a constant adequate flow 
to function properly. If the heating system's valves are able 
to throttle circulation, an overflow valve must be installed.
The circulation pump must press the water through the 

cartridge with the flow direction shown in the system 

diagram.

Flow that is too low increases the difference between 

the desired and the actual temperature, increases the risk 

of that the overheating protection will be triggered and 
the risk of irregular control resulting in increased wear 

on the electromechanical components.

Excessive flow can result in vibrations in the immersion 
heaters with noise and reduced service life as well as 

unnecessary wear on system components.

Flow direction

The circulation pump must press the water through the boiler 
with the flow direction shown in the System principles.

Expansion system

EK 15E must be connected to an expansion system. 

Expansion vessels are dimensioned to accommodate changes 

in water volume due to heating and cooling. Expansion 
vessels, safety pipes, aeration and overflow pipes must 
be installed in a manner that protects against freezing.

  If the electric flow heater's safety pipe is not 

connected to an open expansion vessel, it must 

always be equipped with automatic venting.

Open system

The electric flow heater's flow / safety line must be 
connected in an uninterrupted, uninterruptible pitch to an 

expansion tank installed at the highest point of the heating 

system. In order to avoid oxygenation of the heating system, 

the distance between the top of the highest radiator and 

expansion tank may not be less than 2.5 metres. To avoid 

damage in the event of any blockage in the expansion 

system, the electric flow heater should be fitted with 
a safety valve.
