I had heard the same thing but I can't find anything that confirms the regulation change. As far as I know Title 20 regs still apply. But in reality, it doesn't matter. It isn't policed so you can do pretty much what you want to as long as you can get an installer to do it or install it yourself.

Anyway, what is best for you is a different matter. A couple of questions to get you to the right choice:

1) Where are you located and have you checked for rebates on VS pumps. PG&E offers $100 for a VS and with some of the VS pumps, it can push the price to be competitive with a 2 speed. Some CA power companies are offering better rebates so it is worth checking into.

2) Why do you have such a large pump now? Do you have any water features or a spa?

3) Do you currently have a controller or timer? Some of the VS pumps require at least a timer while others have a built in timer.

4) What happened to your old pump? If the motor just went out you could just replace the motor with a new two speed motor.
