When it comes to air source heat pumps in low temperatures, many businesses and property owners remain apprehensive. Despite rapid advances in air source heat pump technology, outdated assumptions often prevent decision-makers from choosing this energy-saving solution. In this article, we’ll debunk three of the most common misconceptions about air source heat pump performance in cold climates: capacity, efficiency, and cost.
1. Capacity
A common misconception is that air source heat pumps completely lose heating capacity when outdoor temperatures drop. While it’s true that traditional air source heat pumps have historically performed poorly in cold regions, modern inverter systems have significantly increased heating capacity.
For example, the Leomon RS Series delivers up to 90% of rated heating output even at temperatures as low as -20°C. This is thanks to advanced compressor and CO2 refrigerant optimization. Not only do these systems operate reliably in winter, they also provide stable airflow and heating for homes and small businesses in cold weather conditions.
Similarly, the BLN Series offers enhanced cooling capacity even at extremely low temperatures and is equipped with intelligent load regulation and low ambient temperature heating modes. These features allow the system to adjust compressor speed and fan output based on demand – even in cold weather.
So, the idea that cold weather heat pumps can’t handle cold weather is outdated. Choose the right model of heat pump, and your customers will enjoy strong heating without any impact.
2. Efficiency
A common misconception is that cold weather heat pumps completely lose heating capacity when outdoor temperatures drop. While it’s true that traditional air source heat pumps have performed poorly in cold regions in the past, modern inverter systems have significantly improved heating capabilities.
For example, the Leomon RS series can provide up to 90% of rated heating output even in low temperatures of -20°C. This is due to advanced compressor and CO2 refrigerant optimization. Not only do these systems operate reliably in winter, they can also provide stable airflow and heating for homes and small businesses in cold weather conditions.
For example, Leomon’s CO2 cold weather heat pump water heaters are equipped with fully inverter compressors and built-in temperature sensors. Thanks to real-time load matching and heat recovery optimization, it can achieve a COP of over 4.2 even at -15°C ambient temperatures.
By leveraging these core technologies, cold climate air source heat pumps can continue to operate efficiently throughout the winter without a sharp increase in electricity consumption.
3. Money
It is commonly believed that cold air source heat pumps are not worth the money because they require more energy to operate in the winter. While cold air does contain less heat, modern air source heat pumps are designed to efficiently extract and transmit even the smallest amount of heat. As a result, their operating costs are still much lower than traditional electric or gas systems.
Inverter-driven air source heat pumps such as Leomon's RS series do not run at full speed all the time, but adjust power output based on actual demand. This intelligent load adjustment function minimizes electricity consumption, reducing electricity bills even during prolonged cold weather. Over time, the energy savings can offset the initial investment, especially in areas with higher energy costs.
For customers in cold regions, the return on investment (ROI) becomes clear when comparing seasonal energy efficiency. For example, a conventional gas boiler may drop below 90% efficiency at freezing temperatures, while an air source heat pump can still provide a seasonal COP of more than 3.5 at high performance. This means that even in sub-zero conditions, it can generate more than three units of heat for every unit of electricity consumed.
Leomon's air source heat pump series, including the BLN series, is tailored for customers who want to achieve long-term energy savings and reduce carbon emissions. Combined with IoT control and intelligent scheduling, the cost-effectiveness of air source heat pumps at low temperatures will be further improved.
