HI! We are getting ready to build our first inground pool. We live in South Jersey. We have been talking to pool companies and getting estimates/ideas. The Pool Store is encouraging us to get a gas heater. Jersey Pools is encouraging us to get a heat pump. We don't know what advice to take!!!! We plan to use the pool from mid/late May through September. We need help deciding what would be best to go with. We do plan to keep the pool rather warm when we use it. Any advice welcome. Thank you!!!
