Heizung wird nicht warm? Heizkörper Durchfluss einstellen, Voreinstellbares Thermostat-Ventil

Hi welcome to a new video yes in this video I would like to show you how you can fix the problem if your heating is not getting very hot anymore it can still be a bit

warm

in here but downstairs things are as cold as they are probably in your in desperation tried to bleed the heating system here but quickly realized it can't be what could be the reason why you need to know today's

thermostat

ic heating valves have a preset option and with this preset option often a hydraulic adjustment is possible in chinese what that means to you i'll show you how first we have to go and remove the heating

thermostat

many of you will think that's what's going on here no that's just the

thermostat

ic head the

thermostat

of actual heating is below to remove this head the heating should or must be on maximum heat.

In my case level 5 now we go here with standard water pump pliers and loosen the

thermostat

ic head we can even unscrew it with one hand here now let's just look inside this thing this

thermostat

ic head is actually just a pin that you move back and on That means if I turn this here, this heating valve towards level 0, a little PIN comes out here and this PIN coming out has nothing better to do than push the pin coming out of the

thermostat

here, I'm going to just do that and that's what Valve Head does no more and no less, but now let's take a closer look at this heating

thermostat

and let's take a closer look at this

thermostat

ic valve.

I'll just turn on the light so you can see it's better now this white ring you see here it's important if we look very closely we see the numbers 1 2 3 4 up to the number 8 raised at the same time on this white crown and here we see a mark on this nut the height of the mark indicates what stage this

thermostat

is in but what is it really about with this scale I'm going to show you now and these

thermostat

ic valves of course they are produced for heaters of different sizes that you have here but now the consequence that you have to adjust to the size of your radiator that you have, for example, as I am now in my case level 2, only very little hot water comes out of the heating pipes into the heating media, on the contrary, there is still hot water here and it's already cold here It gets cold because the heating is a little bigger I don't use this heating surface at all because there simply isn't enough water going into the heating The example ideal would be hot water going into heater here means it's

warm

and bottom corner should still be

warm

in exaggerated example you're going for big punk here Full throttle would mean hot water there it's hot there is a lot of hot water coming in the whole heating system is very hot and the hot water also goes back into the return line and this is exactly where i have to break the video for a moment because i have to i'm going to explain this very quickly through a short theoretical part with you on how a heating system works yes and then we'll move very briefly into theory I'll try to shorten the whole story here of course to explain to you how a heating system I have here works just take the blueprint of this one apartment as a base, you can see the areas marked in green here, the areas marked in green are the heaters that are installed here in this apartment. nto here we also have the guest bathroom, the children's room, but we are only concentrating on the upper part of the black square.

What you see here is my Buderus heating system in this bathroom. there is also a heater on the wall you can see it here don't be alarmed here in this floor plan the shower is still marked on the heater it was built differently than what was planned here in the floor plan at the time , to do? we need to know about it Heating the Buderus

heizung

stherme produces clean hot water this hot water goes to the pump the pump delivers the hot water here to all the heaters back and forth here on the right just open goes further in each heater there is a branch to each heater like this and so that's the hot water loop i'll change the color let's take it blue each heating system also has a return that usually runs here parallel to the heaters along the hot water pipes here too each heater has a return where the cold water can flow back to the return here too, the return is if the flow rate is set incorrectly it can happen that the Far when you change it back, it means that the water enters the heating system, we have too much flow rate high, that instead of cold water, hot water still flows here, which means that you have unparalleled waste of energy here, that u We still need to know if we change the flow rate here we change it the pressure in the heating system changes here either plus or minus the pressure behind it changes plus or minus with plus or minus that means we have to check the flow at each The heater is started as close as possible to the gas boiler, then it is always worked further away and then if all is well here the heating is perfectly adjusted and with this knowledge we can now make the adjustments here.

I do it with water pump pliers, but there are also special key accessories or a hexagon that we can now vary. I have to get a little bigger flow with me and that has to Now find out for yourself and then I'm changing the heating temperature it should be

warm

and still

warm

at the bottom of the corner if that's the case you have the correct flow rate here and you are using the entire heating surface of the heater again but we have already said right now start with the heater that is closest to the hot springs and continue working for the heating that is further away from the hot springs in the

thermostat

ic valves as I told you most have this setting option yes that was our video if you have any questions write them in the comments i will try to answer as soon as possible give this video a thumbs up i would love that very much and you can use the youtube channel of the tv fix of course i like to subscribe too yes that was our video thanks for watching see you soon definitely in one of the next videos
