A spillover spa does not directly heat the pool. It serves as a connection between the pool and the spa, allowing water to overflow from the spa into the pool.

This helps maintain water circulation and control the water level in both the spa and the pool. Additionally, a spillover spa can enhance the aesthetic appeal of the pool area. When considering heating options for a spa pool, heat pumps are often considered the most energy-efficient and cost-effective method.

Heat pumps use refrigeration technology to quickly heat the spa water while consuming less energy compared to other heating methods. This makes them a popular choice for heating spa pools.
