Heater Bypass?

[gctnj]

I know this is a bit off subject, but I just put in a bypass because I will be installing a heat pump. I am down to a Hayward and the same Raypac you installed. It may be too early, but do you have any advice/opinions on buying the Raypac? Thx

Moved from here.

Both Hayward and Raypak have many model heaters. Which ones are you asking about?

Hayward HP21405T
Raypac Crosswind V 8550

This question was originally in response to a post that had recently installed the Raypac. Looking for owner opinions. These two manufacturers are what my local stores carry.
