- Instructions for carrying out the hydraulic balancing of an underfloor heating system in accordance with GEG on the EMPUR® heating circuit manifold
Attention: The execution of the work requires specialist knowledge and a detailed heating circuit calculation!
You can find more instruction films in our video section on the website at www.empur.com/...
is it important that the plastic tubes are fully filled with water? On our Systen some of them are fully filled and some only half way with water...
It is not necessary for the flowmeter to be completely filled with water. If there is some air in the flowmeter, this has no effect on the regulation of the heating circuit
My heating works well,but the red dots from flowmeter are not moving at all.
The flowmeters are all open( anticlockwise) but the red dots are indicating 0 flow(they are up in column). Do you know what happens?
Any one explain if red disc is down will be warmer or vers wise
turning the transparent valve clockwise closes the valve
@@t6404 Would make sense for a usual valve and that's what video implies, but that means the disc goes up, and it then indicates on transparent cylinder a lower value ...so fewer liters per minute. This still doesn't make sense.
Our flow rate indicators are installed in the flow. This means that when the disc is down, the flow is fully open. The volume flow is therefore greater (more heating water flows through the heating circuit).
what if there is air in the flow meter? does this change anything?
If there is air in the flowmeter above the float, this has no effect on the function of the component. The flow rate can be adjusted.
@@empurgmbh9241 why are the flowmeters installed at the top and not bottom?
I had an issue where the actuator's plastic broke, exposing it and the bleeding valve went and when I went to check the system, it was live since water dripped on the actuator because it was at the on the bottom section of the manifold
Normally the flowmeters are installed in the forward of the manifold (bottom) and the actuators are placed in the return (on top). In case of this it isn´t possible to become water on the actuator if there is same damage.
Why do these adjustment videos assume that I know how long the loops are? It was instslled 25 years ago.
If you don´t know how long the loops are, you can calculate the neccesary flow. Therefore you need the heating rate of the room and the temperature difference between the forward and the return.
It´s also possible to use a special connecting box for the acuators, our article 574113. The system will proceed automaticaly.
@empurgmbh9241 ok...how is heating "rate " calculated, how do I access that article, and what do you mean by "actuator devices?"
The heating rate can differentiate between 30 and 80 W/m² sometimes with 100 W/m² in very old houses. The device can be used to do the hydraulic balancing automatically. The system checks the waterflow in relation to the room temperature. After a certain wile the system will be balaned.
Îs this System only good for underfloor heating or it also works with radiators?
Dear Sir, the hydraulic balancing shown in the film only works with underfloor heating manifolds. For radiators, a different procedure is necessary, which you should ask the manufacturer about.
