We are still in the decision making stage of the construction of our new pool. We are trying to decide if it is better to go with a heatpump or a natural gas heater. We tend to use a pool at night a lot so our goal with the heater will be to keep the water at a comfortable temperature after the sun has gone down. We also anticipate that our swim season will be from from late March through the early parts of November...depending mostly on how warm it is outside. I do not anticipate that we will want to heat the pool during the winter months. We are not having a spa built with the pool.
All that being said...what would be the most economical route to go with regards to energy costs?
