Web27 de out. de 2024 · Heat pumps, which we could also call electric boilers, are the future of home heating. They work by gathering small amounts of heat energy from the air or ground, and concentrating it to warm up your home. The magic of this process means they work whatever the weather, even in temperatures as low as -15C. WebHeat pumps can have problems with low airflow, leaky ducts, and incorrect refrigerant charge. There should be about 400 to 500 cubic feet per minute (cfm) airflow for each ton of the heat pump's air-conditioning capacity. Efficiency and performance deteriorate if airflow is much less than 350 cfm per ton.
