This second part explains how the recorded data can be processed further and what conclusions can be drawn from it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-measuring-correctly\">Measuring correctly<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To ensure the measurement provides meaningful results, two measuring devices are needed.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Measuring device 1<\/strong> records the flow and return temperatures of the heating system.<br><\/li>\n\n\n\n<li><strong>Measuring device 2<\/strong> records the room temperature in the living area and the outside temperature.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is only possible to draw the correct conclusions with these four measured values. This is because the room and outside temperatures must be known to correctly interpret the heating system&#8217;s measured values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The measurement approach can be explained as follows:<br><strong>With a room temperature of 22\u00b0C and an outside temperature of -2\u00b0C, the heating system must deliver a flow temperature of 69\u00b0C. Of the 69\u00b0C supplied, 27\u00b0C remains in the return flow.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This quickly reveals which heating technology is suitable for the building and which is not. Thus, the old heating system helps determine its successor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An important factor in the measurement is the time of year, as it makes little sense to measure in summer. The ideal times for measurement are January and February, when the heating system is working hardest. The best time of day for measurement is at night, between 10 p.m. and 8 a.m., as this is when the coldest periods are recorded. For this purpose, any night-time temperature reduction should be deactivated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One more point to consider is that hot water preparation can lead to measurement errors if there is no return flow barrier between the hot water heating circuit and the normal heating circuit. This can cause the heating water from the hot water system to heat up the sensor in the return pipe. If this is the case, the hot water system must be switched off during the measurement. This means that you will have no choice but to take a cold shower on this occasion.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><a href=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4.png\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"433\" src=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-1024x433.png\" alt=\"The hot water system is running, which is causing incorrect readings.\" class=\"wp-image-110746\" style=\"width:500px\" srcset=\"https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-1024x433.png 1024w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-300x127.png 300w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-768x325.png 768w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-1536x650.png 1536w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4-2048x866.png 2048w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/webseite-fehlmessung-en-4.png 631w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">The hot water system is running, which is causing incorrect readings.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-recording-and-reading-measurement-data\">Recording and reading measurement data<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once the four temperature sensors have been correctly positioned, the measurement cycle can be started either directly on the measuring device or via the website. The temperature sensors will then report the measured values every 60 seconds, which will be transferred to a CSV file. As the date and time come from an NTP server, both measuring devices are synchronised. To read out the recorded data for further processing, the measurement cycle must first be stopped. The data can then be transferred to a PC using an FTP programme via the FTP protocol. WinSCP, a free Windows programme, is a good choice for this. It can be downloaded <a href=\"https:\/\/winscp.net\/eng\/docs\/lang:de?#utm_source=winscp&amp;utm_medium=app&amp;utm_campaign=6.3.4\"><strong>here<\/strong><\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After installation, the two measuring devices must be entered as FTP servers. To do this, you will need the IP address, username and password. The IP address is displayed when the measuring device is switched on. The username and password are entered in the sketch. These can be changed in line 151 of the sketch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s how to proceed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start WinSCP<\/li>\n\n\n\n<li>Open \u2018New tab\u2019 (Neuer Tab)<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><a href=\"https:\/\/212.184.1.90\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-1024x281.jpg\"><img decoding=\"async\" width=\"1024\" height=\"281\" src=\"https:\/\/212.184.1.90\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-1024x281.jpg\" alt=\"Anlegen einer neuen Serverbindung\" class=\"wp-image-110538\" style=\"width:500px\" srcset=\"https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-1024x281.jpg 1024w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-300x82.jpg 300w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-768x212.jpg 768w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-1536x422.jpg 1536w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0-2048x563.jpg 2048w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp0.jpg 655w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Create a new server connection<\/figcaption><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open \u2018New connection target\u2019 (Neues Verbindungsziel) and enter the data<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><a href=\"https:\/\/212.184.1.90\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-1024x684.jpg\"><img decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/212.184.1.90\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-1024x684.jpg\" alt=\"FTP-Server-Einrichtungsmaske\" class=\"wp-image-110540\" style=\"width:500px\" srcset=\"https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-1024x684.jpg 1024w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-300x200.jpg 300w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-768x513.jpg 768w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-1536x1025.jpg 1536w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1-2048x1367.jpg 2048w, https:\/\/www.reichelt.com\/magazin\/wp-content\/uploads\/2025\/10\/winscp1.jpg 638w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">FTP server setup screen (Login)<\/figcaption><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Save the entered data<\/li>\n\n\n\n<li>Click on &#8216;Login&#8217;
