C37 -- Filomena Storm Allowed to Test a HP in a Worst-Case Conditions for Madrid Weather PDF

Snow does not often fall in Madrid, so the heavy winter storms of January 2021 were highly unusual. Filomena storm in 2021 was one in 50 years snowstorm. Outside temperatures dropped to a frosty -10°C (14°F) at night, and snow covered the ground for days. That was an opportunity to evaluate an air to water heat pump, The HP had been installed just two months before the storm, in a three-bedroom flat on the fifth floor of a 20-year-old building, with average insulation. The equipment had a good data registry so all the analytics about the behavior of the system were easy, the results have shown how well it worked during those 10 days period of harsh conditions. The heat pump was able to keep a comfortable temperature of 22°C (72°F) in this 100 m² apartment in the Spanish capital city. Hot water supply was also continuous. Even in the days of extreme snow and cold, the heat pump was twice as efficient as the most efficient gas boiler, showing the superior performance of the equipment in these especially difficult conditions. It was constated the system’s carbon emissions were four times lower than they would have been with a gas boiler. This was even despite the unusual cold, dark weather meaning less renewables-based electricity was available. What is more, the heat pump never produces any harmful air pollutants, (NOx) unlike fossil fuel boilers. And when the Madrid weather got back to its more normal, warm conditions, his heat pump was ready to supply air conditioning. In 2022 the summer was extremely hot in Madrid and again the performance was outstanding. The quick conclusion is HP in Madrid is a perfect solution!
