Integrated Spas
Integrated Spas combined with swimming pools are very popular, an integrated spa and pool combination works well as you can utilize the one filter, pump and sanitizer to maintain the clarity and chemical balance of the water for both the pool and spa.
Integrated spas can be operated manually or by remote control systems, with the correct plumbing configuration the pipe work can be valved to circulate the water from the pool, returning to the spa then cascading back to the pool, this configuration would be utilized for normal day to day operation. When using the spa only, the plumbing configuration is valved so the water is drawn from the spa and returns back to the spa, bypassing the pool, thus allowing the spa to heat without returning heated water unnecessarily back to the pool.
