Please don't worry about this problem. Copper is a very soft metal. The copper sheet on the parts will inevitably be squeezed and impacted during the transportation of materials and parts, resulting in some dents or minor scars, which will not affect the performance and service life of the product.

The operating noise of different models varies greatly, from about 30 to 60 dB. Here are some examples: -30dB is similar to the voice of human whispers. -40dB is similar to the sound of refrigerator operation. -60dB is similar to the voice of normal conversation.

Customers can read our product catalog, browse different product introductions, and then decide which one to choose.

The heat pump will not emit any pollutants during operation, but attention should be paid to equipment maintenance to avoid refrigerant leakage.

We promise that if the main parts of the product are damaged due to quality or process problems within 24 months, we will guarantee the product.

The heat from the sun is stored in the air year after year so that we can get a constant source of naturally renewed energy. This stored energy is ideal heat source for your daily domestic heating demand. The air source heat pump collects heat from the solar energy stored in the air. The heat is collected and carried by refrigerant and then converts it into high grade heat to be released to your house by underfloor heating system or radiator and into your domestic hot water tank. ● The solar energy stored in the nature can be brought up by a heat exchanger called evaporator. Here the refrigerant absorbs the solar energy and turns into very low temperature gas. ● The gas refrigerant is compressed and turns into very hot and high pressure gas, then the heat is transferred to the water-based heating system in the house by a condenser. ● Then the refrigerant reverts to low pressure liquid and is ready to collect new solar energy.
