I'm not positive but, as far as I know, one is required on a 120V heater but not on a 220V heater. Even if a GFCI isn't required I would install one anyway for the safety of your family and friends. These devices do work and are well worth the cost. Call a Professional... Either a GFCI outlet or a GFCI breaker, and I think I'd use the GFCI outlet because the reset on an outlet is closer to the pool than the breaker would be. But put it far enough away from the pool that you've got to get out to reset it. I think that's code; if it's not it should be.
A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
It is a Ground Fault Circuit Interrupter or GFCI. It can either be equipped in your electric panel as a GFCI breaker, or in a GFCI outlet which also lets you extend the GFCI protection to other outlets "down the line" from the GFCI outlet.
I would NOT do that if I were you. If someone is electrocuted and local, county or state officials discover that the GFCI has been removed, you could have some serious problems in court.If a GFCI was installed, there was a good reason for it; electricians don't put one in unless it is required by code.If you INSIST on replacing the GFCI, connect the white wire that screws into the GFCI to the neutral bar in the breaker panel and disconnect the white pigtail that comes out of the GFCI, then connect the BLACK wire to the new breaker.
No, you could use a GFCI circuit breaker instead.
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.
A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
GFCI = Ground Fault Circuit Interrupter.

There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.
A GFCI receptacle can extend its protection to regular receptacles connected to the output side of the GFCI. Each actual GFCI receptacle should be directly connected to a breaker in electric panel.
