The Pentair MasterTemp 250K BTU High Performance Pool & Spa Heater (460806) delivers 250,000 BTU with the heavy-duty cupro-nickel heat exchanger rather than standard copper.
That is the whole point of the HD designation. Copper heat exchangers corrode in salt-chlorinated water and under aggressive chemistry; cupro-nickel does not. If the pool runs a salt system, sits in a hard-water region, or sees chemistry that swings, the HD version is the one that survives.
The trade is a small efficiency cost - 82% thermal efficiency against 84% for the standard copper version - easily outweighed by not replacing an exchanger every few seasons. Everything else carries over: fast light-off, quiet operation, a rotating digital display that faces whichever way the unit is installed, and a built-in manual gas shutoff.
