These are the manufacturer's published terms. Terms can depend on the installer, the dealer program and where the heater was bought, and they change without notice, so we confirm the exact term for your install on the written quote.
Titanium doesn't corrode in pool water, so it's the standard on quality heat pumps and the reason a heat pump can sit on a salt pool for years without exchanger trouble. It costs more, which is why it's rare on gas heaters, and the ETi 400 is the exception here.

The MI900 is rated at 82,000 BTU/hr heating output. Heater size comes from your pool's surface area and the temperature rise you want, not from gallons, and the pump and plumbing have to deliver the flow the heater needs. Use our heater size calculator for a starting number, and we confirm it on site before quoting.
Yes. The MI900 has built-in Wi-Fi, and it also connects to automation through a relay.
