Have a 20,000 gallon pool. Will the this heater be enough or should I get the 400,000 BTU. Don't really care if the 333,000 takes a little longer to heat up the pool

The 333,000 would be more than sufficient for a 20,000 gallon pool.

My heater motherboard is defective and it won't turn on the heater. Can we just replace the motherboard? Do you carry motherboards for this heater?

GM, Can the 333k btu unit be changed over to a NG unit at a later date replacing an inexpensive part or must we buy another unit? We currently use propane but just got our house switched to NG and were thinking of running the pipe to the heater within a year or two.
