In the past few decades, heat pump has entered more and more families, including China, the United States and many countries in Europe. However, in the cold winter season, many families will wonder: can the heat pump work in cold temperatures?
Many experts said that even in cold weather, the air source heat pump systems could still be more efficient and more effective in protecting the environment than furnaces and boilers using fossil fuels.
With the development of heat pump technology, more and more heat pumps are used for household heating and cooling, and the technology is becoming more and more mature. Many of these products have helped many families who need heating in winter and cooling in summer.
This heat pump, which integrates heating and cooling, is essentially a two-way air conditioner. In summer, its function is like a traditional refrigeration air conditioner, which draws heat out of the home and circulates cooling air indoors. In winter, it absorbs heat into the home. Even if it is cold outside, there is still heat. Of course, as the weather gets cold, the heat pump has to work harder and use more energy to extract heat.
But even in cold weather, the heat pump is more energy efficient than the gas or oil stove. These furnaces generate heat by burning fuel. Theoretically, for each unit of energy input, they can only produce one unit of energy output. In fact, even the most efficient gas furnace cannot convert 100% of fuel into heat. Some are always lost during conversion.
On the contrary, the heat pump does not produce heat. They transfer heat from the air. This enables them to achieve 300% or even more than 400% efficiency in some cases. Sam Calisch, special project director of the non-profit advocacy organization Rewiring America, said that because heat pump is more efficient, using heat pump to cool and heat houses can help homeowners save electricity costs.

Many heat pumps working in cold climates do have relatively high early prices. However, based on the goal of environmental protection and carbon neutrality, many countries provide subsidies homes who install heat pumps, even up to 5000 pounds in the UK.
With the increasing popularity of heat pumps, heat pumps system have become more and more misunderstood, sometimes even erroneous information. Fossil fuel industry groups have been the source of many exaggerated and misleading statements, including the statement that they cannot work in cold climates and are likely to fail in cold weather.
Although the efficiency of heat pump is reduced at the temperature below zero, many models can still close to normal operation at the temperature of minus 35 ℃. Some of the latest models are even more efficient. Many “cold” countries, such as Norway, Sweden and Finland, are increasingly using heat pumps.
Solarshine’s air-source heat pump for heating and cooling is easy to install and operate efficiently. It can still work at minus 35 degrees Celsius, and can become the choice of countries with cold winter in Europe, the United States and other countries.
