You should get a professional to do this install. There is something not right about what you are saying. I don't think heat strips and the pump itself would be on the same circuit. If you mean 95 amps for just the heat strips, that is also wrong as the national electrical code limits a heating circuit to a 60 amp breaker and 48 amp load. That's another thing you aren't mentioning, the requirement to have a breaker rated 125% of the heating load. And you don't know if you need 90 or 100. It is obvious you do not know what you are doing. Get a professional before you kill someone.

2 gauge copper stranded wire will support up to 95 amps.
1 gauge copper stranded wire will support up to 120 amps. i like to be 1 gauge size larger than the minimum requirement is a safe rule.
1 gauge would be safe for you. in addition, this allows the ability for a variation in the current draw.
check the chart at this web site for further gauge/wire amp tolerances.
good luck.

100 amp breaker you should use wire size #2, but check with your building code in your town.
