Which is the best way of solar heating an indoor public swimming pool to save operating costs?
I am in charge of an indoor public swimming pool. Its size is 50m x 25m and every month approximately 3500 swimmers use it from 07:30 to 22:00 daily. For now only oil is used for heating the pool and for the other water uses (shower etc.). I am looking for a different way of efficient heating the water using the sun to save on our energy costs. Please give me information about this. Thank you in advance for your tips and advice.
Using solar thermal collectors for a public pool is more of a commercial application, where we specialize in residential building solutions. We see people build a lot of DIY solar water heaters for backyard pools, but I think you would be subject to greater scrutiny with municipal building inspectors for public health and safety reasons, so I don't think we can help much on that, sorry!
