Compared with ten years ago, today's indoor swimming pools are no longer new in the city. Venues, schools, and even become standard equipment for high-end communities. Indoor swimming pools generally need to be kept constant temperature, and it is unnecessary to say how much energy is consumed every day. The heating cost of traditional gas boilers , oil-fired boilers , and electric boilers is very expensive and is beyond the affordable price of ordinary units. Even new energy equipment such as heat pumps only reduce part of the consumption and still cannot change the reality that traditional energy and costs remain high. The following is a comparison of several types of energy swimming pool heating:
swimming pool is a large water system, ranging from dozens of tons to hundreds or thousands of tons. Maintaining the pool constant temperature requires a lot of heat energy every day, which is a huge expense in the long run.

Take a 50m×25m×1.8m indoor swimming pool in North China as an example. When the pool water temperature is kept at around 28°C all year round, the daily heat needs to be replenished is about 6.74×106 kcal, which is about 7800 kWh of electricity or 900 cubic cubic natural gas . According to the 300-day business hours of indoor swimming pools under normal circumstances, the annual energy consumption is:
☆Electric boiler requires electricity: about 2.6 million kWh; (small equipment investment, high energy consumption)
☆Gas boiler requires gas: about 270,000 m3; (small equipment investment, high energy consumption)
☆High energy consumption)
☆High energy consumption)
☆High energy consumption: about 900,000 kWh; (large equipment investment, high energy consumption)
☆High energy consumption: about 650,000 kWh. (The equipment investment is large and the energy consumption is high)
shows that traditional energy equipment is not desirable; and new energy equipment also has large investment, long recovery period, high costs, and cannot fundamentally solve the problem of low-cost operation. In addition, the above equipment needs to consume traditional energy, which will have a certain impact on the environment to a greater or lesser extent.
data shows that in developed countries, about 70% of swimming pool heating projects are used, and the solar constant temperature system is a better solution, with the advantages of more energy-saving, more economical, environmentally friendly, renewable, and sustainable.
indoor constant temperature swimming pool
swimming pool solar constant temperature system: mainly solar energy combined with waste heat reuse device, or with heat pumps, gas boilers and other equipment, to form a complementary system, referred to as the 'solar+' system. The system is arranged on the roof of the swimming pool or nearby for easy utilization. Under sunny weather conditions, the use of solar energy systems as the constant temperature guarantee heat source for the swimming pool. The auxiliary heat source for starting the rainy weather provides the system with a heat source, and the system automatically runs unattended.
Under normal circumstances, a standard swimming pool uses a solar heating system to invest slightly higher than water, ground source heat pump system . However, solar energy bears most of the load on the pool's constant temperature, and this part of the energy comes from the clean and free sun!
Industry data shows the benefits generated by the 'solar+' system:
☆ Compared with using electric boiler systems, investment costs can be recovered in the same year.
☆ Compared with gas boilers, investment costs can be recovered in about 2 years.
☆ Compared with heat pumps, investment costs can be recovered in about 3 to 4 years.
According to the 15-year service life of the ordinary ‘solar+’ swimming pool constant temperature system, the ‘solar+’ system continued to work with a smaller operating expense for more than ten years, bringing generous returns to users! Compared with other energy forms, the 'solar energy +' system can save money for a standard constant-temperature swimming pool (excluding auxiliary energy consumption) as follows:
☆ Compared with electric boilers, it can save about 34 million kWh; (by 14 years)
☆ Compared with gas boilers, it can save about 2.8 million m3; (by 13 years)
☆ Compared with air source heat pumps, it can save about 8.6 million kWh; (by 12 years)
☆ Compared with water ground source heat pumps, it can save about 5.7 million kWh. (By 11 years)
or above is calculated based on the minimum consumption of a certain area for reference only. The actual situation varies greatly. Friends who operate indoor swimming pools can compare and test and find an energy-saving method that suits them!
