Snow does not often fall in Madrid, so the heavy winter storms of January 2021 were highly unusual.
For Samuel Peréz, they were an opportunity to test his air to water heat pump, which he had had installed two months previously by Iberdrola Smart Clima.
Outside temperatures dropped to a frosty -10°C at night, and snow covered the ground for days.
But the heat pump kept a comfortable temperature of 22°C in his in his 100m2 apartment in the Spanish capital.
The hot water supply was also continuous.
“Even in the days of extreme snow and cold, my heat pump was twice as efficient as the most efficient gas boiler”, says Perez, who leads Iberdrola’s heating team.
Perez particularly noted 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’s more, the heat pump never produces any harmful air pollutants, unlike fossil fuel boilers.
And when the Madrid weather got back to its more normal, warm conditions, his heat pump was ready to provide air conditioning. A perfect solution!
