Will this heater heater 14,000 gallon pool
Hi John, yes, it will heat a 14,000 gallon pool, but set your expectations on speed. The 106A is Raypak's smallest heater at 105,000 BTU, and 14,000 gallons sits at the top of its range. Plan on roughly 1 degree of temperature rise per hour, so warming the pool from cold is an overnight job rather than a quick afternoon.
It's a solid fit if you mainly want to hold a temperature or extend your season, and a solar cover makes a big difference by cutting both the heat-up time and the gas use. If you want faster heat-up on a pool this size, stepping up to a higher BTU unit gets you there quicker. Let us know if you'd like a recommendation on the right size.

How much heat will this unit put out for just the spa
This heater is rated at 105,000 BTU, which is the total heat output. For a typical spa, that usually translates to fairly quick heating, but the exact heat-up time depends on the spa size, starting water temperature, and outdoor conditions.
If you can share the size of your spa, I can estimate how quickly it will heat up.
