Things to note when buying an air-energy water heater:
1. Look at the samples
Professional large manufacturers have had many large-scale projects and samples in the past, especially in cold weather In the north and even Tibet, companies with more model projects have more stable products and stronger technology and energy saving. The constant temperature of the water tank should be good. This function is based on the needs of customers. The constant temperature function can ensure that the water during bathing will not be hot and cold, and avoid scalding customers, especially for families with the elderly and children. At the same time, it can meet the needs of customers. A household's winter hot water needs.
2. Look at the weight
The main accessories of a standard equipment should be composed of compressor four-way valve, electronically controlled casing, heat exchanger, fin heat exchanger, etc., and Some manufacturers use false standard heat for smaller presses and heat exchanger assembly equipment, but the direct heating power of their equipment is far from the marked value. Taking a standard 13 HP direct heating equipment (PASHW130SB-2-C) as an example, the standard brick net weight is 310KG.
3. Look at the service
This is also the most important point. The three-guarantee policy of professional manufacturers of big brands is 6.5 years of free repairs, while small copycat factories have Due to product quality and other reasons, the warranty is only for 2 years. There are two types of air-energy water heaters: all-in-one and split-type water heaters. Today, most customers choose all-in-one water heaters. However, all-in-one water heaters have a disadvantage, which is that maintenance is more troublesome. Therefore, if the space where the water heater is installed in the home is not particularly small, it is recommended to use split-type water heaters. body machine, which facilitates maintenance.
4. High energy efficiency ratio
The biggest advantages of air-energy water heaters are low operating costs and good energy saving. This is an important reason why the public chooses air-energy water heaters, so in When choosing, choose an air-energy water heater with high energy efficiency.

Advantages of air-energy water heaters
The biggest advantage of air-energy water heaters is energy saving. It converts low-temperature heat energy in the air into high-temperature heat energy through the compressor. Based on the same hot water production volume, compared with electric water heaters, it maximizes energy savings and the use cost is only 1/4 of electric water heaters.
Compared with solar energy, air-energy water heaters are more convenient. Whether they are installed indoors or outdoors, and whether it is cloudy or sunny, they can be used easily as long as there is air. Air-source water heaters use air as the main body and are highly efficient and energy-saving. They not only save people's usage costs, but also conform to the mainstream of energy conservation in the world. Moreover, it uses the new international R134a environmentally friendly refrigerant, which also makes it more environmentally friendly and efficient.
