Hi Troy and thank you for your question. Are you trying to extend your season by a month or 2 or do you want to be able to swim year-round? You can use this guide if you have an inground pool and this guide if it is an above-ground pool to calculate what you need. Per the inground heater recommendations, your pool would need to be about 150 square feet or less in surface area to get a 1 degree per hour rise in temperature for this 62,000 BTU heater. Do not neglect the cost of running your pump while the heater is running as well. It is generally more economical to get a larger heater to keep your pump running less. Send us some more details and we would be happy to help you select a properly-sized heater.
