The cost of the air-source swimming pool heat pump is higher than that of the electric heat pump and the gas heat pump, but the air-source heat pump is more efficient, easy to install, and can save up to 75% of electricity costs in long-term operation. With normal maintenance, its service life can exceed 10 years. It is the best choice for energy-efficient and environmentally friendly heating equipment.
When choosing a pool heat pump, you need to consider:
Pool size
We can choose the appropriate air source swimming pool heat pump model according to the pool water volume. The size of a swimming pool is usually measured in cubic meters (m3).
For example, for a rectangular or square swimming pool, 1000 liters = 1 cubic meter. For other curved pools, 1000 liters = 0.78 m3 (circular pool) = 0.89 m3 (oval pool) = 0.85 m3 (bean-shaped pool).
Season/time of pool use
We need to know the season/time when the user uses the swimming pool, then recommend a low-temperature heat pump or a normal-temperature heat pump for the user, and estimate the approximate initial water temperature to calculate the heat pump model.
For example, if the user needs to use the swimming pool heat pump in a working environment of 7℃-43℃, we will recommend the normal temperature type heat pump. If the ambient temperature is lower than 7℃, it is recommended to use a low-temperature heat pump, because the normal-temperature heat pump generally does not have an intelligent defrosting function, if the ambient temps. is lower, the unit will stop working and frosting may also occur on the surface of the unit, which requires the user to defrost manually. In addition, frequent shutdown and operation will shorten the service life of the unit, and it will not be able to well meet the heating needs of users.
Target heating temperature
The temperature of the pool water determines the comfort of swimming. Different users have different requirements for the temperature of pool water heating. The general swimming pool water is heated to 26°C~28°C, but some customers need to heat the pool water to about 40°C, which requires a larger amount of heat from the unit. For example, for a 20m³ swimming pool, the operating range of the unit is 18°C~43°C, and the pool water needs to be heated to 28°C and 40°C, requiring a 9.7KW heat pump and a 10.7KW heat pump respectively.
Heat pump efficiency( COP)
COP is the ratio of heating capacity to electricity consumption. The higher the COP, the higher the heating efficiency of the heat pump and the more power saving. The COP of a heat pump is usually affected by three conditions: air temperature, water temperature and humidity. For example, a swimming pool heat pump with a COP of 8 means that it can convert 1kW of electrical energy into 8kW of heat to heat a swimming pool at A15°C /W26°C / 70% humidity.
Budget
Your purchase budget is based on your needs, such as your current needs, future needs, and additional features of the product. If you only consider the current needs when you buy a heat pump, for example, you only need to find a swimming pool heating equipment that can only heat the pool water, then you have many options, such as electric heaters, gas heaters, water or ground source heat pump, etc., but the installation cost and long-term use cost of these heat pumps are higher than that of air source heat pumps. But if you consider the current needs and the cost of long-term operation in the future when you purchase a heat pump, the purchase cost of an air source heat pump is higher than that of traditional heating equipment, but in the long-term operation, it can help you save a lot of money.
