Winter -12°C ❄️🏠 Wärmepumpe im ungedämmten Altbau? Meine Baufehler

The ultimate test for my 12kW heat pump! In this video, I'll take you through 24 hours of extreme stress at temperatures as low as -12°C. Can a heat pump really keep a 120-year-old, uninsulated building with solid brick walls warm? My equipment & recommendations from the video: 🛠️ Here are the components I use for my system in the 120-year-old building: Heat pump: Panasonic Aquarea Monoblock (similar model) – The heart of my heating system, which even lasts at -12°C. Buffer tank: https://amzn.to/4sG2GVg Measuring equipment: Infrared thermometer / thermal imaging camera – This is how I located the thermal bridges in the 39 cm brick wall. https://amzn.to/4jxUD8y Energy monitoring: Shelly 3EM for electricity measurement – ​​This allows me to keep a close eye on my daily consumption of 83.8 kWh. https://amzn.to/3N85Xwh Smart home control: Radiator thermostats – For fine-tuning the temperature in the upstairs rooms. https://amzn.to/4pD5Fux Note: These are affiliate links.
