    Hotspot FPH AC heat reclamation pool heater - a review!

    Understood, xr4, good thoughts. Yup, I think the pool covers are a pain from almost every vantage point. They work to some degree, but have so many issues and downsides. And even with a 10 year warranty on a "high quality" one that you manage to cut to fit, clean and retract and reroll...

    Hotspot FPH AC heat reclamation pool heater - a review!

    There is a wealth of info in that 9 pages, but I'll bite with a quick answer too :-) I agree with Joshii, it won't be worth it. As stated somewhere in the volumes above, I got about 17% savings on AC cost. Knowing what that really saves you means knowing what % of your power bill is due to...

    Hotspot FPH AC heat reclamation pool heater - a review!

    A member direct messaged me asking about what I used for brains & automation in my FPH system – I thought I would share this update in case it’s useful for others….. I'm not sure if you managed to read all that was posted across what now seems to be eight pages of posts to this FPH review...

    Hotspot FPH AC heat reclamation pool heater - a review!

    I know this thread is old, but a question came directly to me this week (November 2019), so I post the answer below, for the benefit of others in the forum. Q: Hey! I was wondering if you could recommend someone to install the hot spot heat exchanger. I'm in Orlando and struggling to find a...

    Pool Motor failed after 3 weeks. Company won't replace motor because it shorted due to being wet.

    This thread is perfectly timed for my question, thanks all for replies to date. My question might be rhetorical because I suggest an answer below, but why in the world are so many popular pumps built with motors that have sets of vents that so easily expose the windings to splash-up from a hard...

    Hotspot FPH AC heat reclamation pool heater - a review!

    A couple folks asked me if my FPH is still working. hence a quick update: It was still working fine after three years of use, then I sold the home. I learned later that the new owner replaced the AC system, so I presume he tossed all this out, or sold it :-( I have a new place now with larger...

    Ever hear of an air switch occasionally self-activating?

    I know this is an old thread but a couple folks reported the same problem - in this thread and in email - so I thought I would update the topic with a couple fixes I deployed. I also encountered this same problem on another RC2343PT, although with a different failure mode. In the original case...

    Hotspot FPH AC heat reclamation pool heater - a review!

    Good ideas Eric, thanks, keep em coming! Although it would be great to use flow or even minimum flow rate as additional controls, doing so does present some conundrums of logic. Consider first a system at rest with pump off when FPH calls for pool heat. With no flow at that startup point in...

    Hotspot FPH AC heat reclamation pool heater - a review!

    I guess that's at least 3 of us posting here that have an FPH from Hotspot running. I still love mine, very efficient, green and all that. But I wanted to post an update about it, in part to point out what may be obvious, that somewhat complex systems like this can be - well - complicated...

    Hotspot FPH AC heat reclamation pool heater - a review!

    I've had an FPH running here in Southwest Florida (Naples) since late 2012, for 2.5 years now, loving it. I'll post a full review in a new thread soon, I'm just catching up to some TFP topics since I've not been a member for very long. Just a couple thoughts for now, and questions welcome...

    What the HECK is T-H-I-S???????

    If I had known the pool doubles as a mole trap I would have put in a pool when I lived up north! LOL Down here in southern FL the worst I fished out was a small snake, a very excited little creature - eeek snakes really bug me. Still, I set him free in the yard :-)

    Ever hear of an air switch occasionally self-activating?

    Thanks again for the ideas. No spa cover there, but a clever thought! I blew air through the 35 ft of 1/8 tubing today, no water came through but I may need to try a compressor that is better than my 1 gal cheapo. Also need a helper there to watch if "anything" is really coming through -...

    Ever hear of an air switch occasionally self-activating?

    Thanks very much guys for the replies, I'll especially chase the water in the air line angle!

    Ever hear of an air switch occasionally self-activating?

    Hello all - I'm trying to help some friends who have been plagued by a spa air switch that seems to self activate from time to time. I'm wondering if anyone has heard of that before. Their pool is a 10K gal IG gunite, spa alongside using the main 240V pool pump and 240V blower, controlled by...
