Heat pump in North Texas and other equipment questions
I'm getting bids for pools now and I had a couple questions about some of the equipment that I've been quoted.
One vendor heard me ask about heat pumps and actually put one into the quote. He spec'ed the Jandy EE3000-R. I don't find anything on this list (which I've read back a couple years history and do lots of searches on :), but I saw where Kelly has the older version (AE3000) in his mega-pool.
What I'm wondering is
a) how much does a heat pump extend the season realistically? A $6k upfront and $200 a month increase in utilities ($0.09/kwh here) seems like a fairly good trade off if I'm swimming 10-12 months a year (using a solar cover of course). North Texas has fairly mild winters, but we do get a couple cold snaps a year normally (or abnormally this year with a foot of snow)
b) how much does one of these guys *really* cost to operate? When pressed, he said that he really didn't install many, but he was looking at putting one in in order to *chill* his pool since his gets full sun and is in the upper 90s in August (when we are ~105* for a few weeks).
Our pool will be on the north side of the house and the second story over the garage will shade the pool/back yard most of the afternoon. I'm not sure the cooler will be super important for us?
Also he uses/recommends the Jandy Stealth pump. Others are recommending either a variable pump or a standard pump with upgrade to variable options. Any recommendations there? ePump is something I've seen mentioned here various times.
Thanks for the help and as I get further in the process I'll be back :)
