I know it's stupid to make another video like this because somehow the videos seem to run better in which I present you with things that are very expensive at the beginning and then after 15 to 20 years have finally paid off well if you like that If you're looking for a video then it 's best to click here and this video is about investing in something under €100 and which will bring you back this €100 within the first year , so if you're up for it then stay tuned and let's go and no, it's not about a warm jacket, it 's about smart thermostats, but I still need the jacket, [ __ ], and for that I'll go to the hardware store for a moment [music] yes, the hardware store unfortunately didn't have any more, but I have to Fortunately, a few months ago I bought another part like that, so it's medium smarter, it can also be very smart if you have an access point, it cost €40 at the time , but I also saw it in Obi en there were somehow still for 10 €, these thermostats that's why I came up with the idea for the video and what are now just smart thermostats so if you can see a scale there are the normal stupid thermostats for less than 10 € in the hardware store we all use the numbers from one to five we set a number this number stands for a temperature and when the temperature is reached then these thermostats switch off then we have all the smart thermostats there is an app that can be controlled via the internet if If you want, you can also get climate data or anything else because you can control the whole thing digitally very precisely.

Additional costs are normally between 60 and 100 euros at the moment. Set the heating to 20 degrees make it yourself and in between there are these half-smart thermostats somewhere and these devices can't get any data from the Internet but they have a built-in clock with the date display and they also have a temperature measuring device and what you can do with it is you can simply say I would like to have on certain days or on all days not at the weekend or during the week I would like to have from the temperature following a time until the next time and the rules then simply normal like yes, both the smart and the stupid thermostats then regulate the temperature in this area and because there is so little technology there is such a clock and a little mechanical one part on and off there are those on special offer I've already seen them for 10 € 15 20 euros for that you get them when I made my video on reducing heating costs I found out that you can save about 6% on heating costs for every degree that you lower the temperature in your room , of course I also asked, just like in the coming taren I'm not there yet, I'll just set my heating to 0 degrees, that means I save 120 percent, then you have to give me money, no, of course not, I've now taken a closer look at the data to understand how this value comes about In the end we also agree that these six percent are correct, but only up to 16 degrees, why is that it's quite simple, there are months when it's over 16 degrees outside and there are more months than months where it's over 21 degrees is and that means if you just look at it I'll show you the months briefly so we have on the one hand we have here with December that is the coldest take January is coldest that's roughly how it is with the temperatures if we say maximum temperature here now it's around 19 degrees there, that means if we draw the line here with 20 degrees, then we hardly have to heat it here at all, that means there are three months in which we actually I don't have to heat at all, even if we always have the heating on , but now we get the 16 degrees here, then see we're here, zack zack, then suddenly it's six months in which we don't have to heat if we only heat to 16 degrees and stuff like that it comes about so here this area is of course bigger zack than this area if we heat 16 degrees and so on it goes if we somehow only heat to two degrees in the end then we would hardly have to heat any more so that's the logic that is the explanation of how it came about in the end , but we'll just assume 6% is right, that's a bit of a calculation, that'll happen and then you should n't let the temperature drop below 16 degrees because it can very easily happen that below 16 degrees because the humidity also settles in the walls and that mold forms there and that is to be avoided very much because that can be really expensive because the g In the end we didn't save all the heating costs anymore, so now we do n't want to freeze either, so we always heat our apartment to 20 degrees and one problem with that is that I can only manage to be in one room and in the hallway at the same time, we hardly ever manage to do it 13 times Being at the same time means a lot of rooms are simply not used and are still heated and there is potential for savings and now of course you can really turn down the heating every time you leave the room and turn it up when you come back in and then you have a problem but at night and when you let something cool down for the first time at night, for example , then it takes more than an hour in the morning until it's up to temperature again and that's of course not very helpful if you want to have breakfast much earlier and that's why we're coming here now So these means clever thermostat come into play because they save you all this work and that Is it done in such a way that we lower the temperature in the bedroom during the day and then lower the temperature in the living room and dining room at night because we don't need all the heat there and that's important to note you can of course also change the temperature in between , so it's very, very tight in there zack zack zack zack you can always set the temperature manually according to the system somehow in a room that then wants to be warm, so we don't have to be committed to it forever and I'm not going to show you complete instructions now, my goal is just you just to prove that it's possible to do something like this without a plumber that 's really anyone can do it and the first step of the instructions is simply click on the subscribe button below and activate the bell so you don't miss a video so and now I'll show you how quickly you can change such a thermostat for that we only need one and no Ang st we won't get any water out now if I loosen this screw here, zack and you almost let go with the hand screw and then you put your new thermostat here and write it down by hand and now you have to all you have to do is make the small arresting movement, so that means you have to adjust the distance between these small pins in the small valve and yes its push button and then the whole thing is already installed and then you can also set your temperatures here on the display zack zack zack zack zack zack zack and much more importantly you can also program the whole thing and how much can you save now so I'm just going to assume that you like your apartment at 21 degrees when you're there and that's okay for you if the temperature will drop to 16 degrees when you 're not there and I'm assuming now that you're lowering each room about half the time for me it's a bit bad worse because I have two rooms that I heat and because I'm also in the home office but if you drive to work then you can definitely lower the rooms more than half the time, so it's worth it Whole thing even more that means if the temperature drops by 5 degrees 5 degrees times six percent we are at 30%.

However, we only do it half the time, which means that we save a total of around 15% on heating costs. Save percent with such a small investment. Okay, to be fair, we have to say here in the kitchen, for example, that if I let it cool down to 16 degrees at night, it takes a while It takes an hour for it to warm up again, which means I have to activate the heating earlier and more heating energy is used than if I let it run through as standard, so let's say I save maybe only ten percent instead of 15 percent and it 's still the same really awesome because I used to have a heating cost deduction of 100 €, that will now increase because there will be more per month, so 10% of 100 € is 10 € month 120 € a year if that now doubles then I have 200 € in the year Month that's 20 € or 240 € a year and now you have to consider that in the winter months the majority of the heating costs are only incurred in the h If you buy another thing like this now, you can easily have it back within the next 1 2 3 months because it saves the largest part of the heating costs right there , so go get one of these things now, it's probably still worth it this year and it's not great that you can buy something now that I'll pay out within the next few months, so where you have a direct return on investment, so to speak, and every further year that you use these things just brings you a net profit of over 100 euros me I think it's great so I'm really happy that I did it but be careful if you have a heat pump then you should n't lower the temperature but hopefully your heating installer has already explained that and if not then subscribe to the channel I will definitely add it later make your own video and yes otherwise skin in the comments if you have already installed such things t okay maybe you need instructions on how to program things, not just install them and uh, where you just found bargains from these things, so where do you get these cheap, clever thermostats I'm looking forward to the next video and see you soon
