I am in the process of finalizing my equipment choices for a new build and was told by my builder that a VSP in Texas wouldn't be a cost saver due to such warm temps in the summer. They are recommending a 1-speed, 2hp pump for a 15k G pool. They gave an example of a VSP working well in San Diego because the temps are consistent and the pump could run at lower speeds most of the time. It left me a bit perplexed since about 8 months out of the rest of the year, outside of peak summer months, North Texas has mild temps. Does anyone have any experience with a VSP vs. 1-speed pump in Texas as far as energy savings? I am trying to figure out if it is worth the additional cost to go with a VSP. Thanks!
