cost of heating a pool. However, the overall cost depends on several factors such as the size of the pool, the climate, and the efficiency of the heating system. Gas heaters have a lower upfront cost but can be more expensive to operate in the long run due to the cost of natural gas. Electric heaters, on the other hand, have a higher upfront cost but are generally more energy efficient and cost-effective to operate. Additionally, electric heaters produce fewer emissions compared to gas heaters, making them a more environmentally friendly option. Ultimately, it's important to consider your specific needs and budget when deciding whether to heat your pool with gas or electric.
