Hayward HP21104T Pool Pump
I felt compelled to write a review about this product, in an effort to pass along some helpful information to anyone who's looking for an unbiased review, and who's circumstances may be similar to mine. First, I would like to mention that I had many pre-purchase concerns about the effectiveness of heat pumps due to the fact that I live in Northern New Jersey and have a fairly large vinyl in-ground pool. Also, this unit was replacing an older heat pump that came with the home when I purchased it, that never seamed to work right, which added to my heat pump pre-purchase anxiety. At first, I was dead set on purchasing a gas heater, but eventually I had to rule gas out after learning that the gas line had to be run underground directly from the meter, and I was unwilling to have some recently done landscaping dug up. (Running the gas line was also going to cost much more than I had originally thought.) But, after purchasing the HP21404T, and having it installed, this unit has surpassed my expectations thus far, and has put all my pre-purchase concerns about heat pumps to rest.
Pool Pump So far and Great Product
Here is a breakdown of my initial results: After finishing the install on a Friday morning in early June in New Jersey, I put the heat pump on and set the temperature to 83 degrees. Keep in mind that I keep my pool uncovered, and the current or starting temp of my pool was 67 degrees at that time. It took about 28 hours of continuous run time to reach my desired temperature of 83 degrees. I was very satisfied with the initial performance of the heater and we were enjoying the pool that Saturday afternoon. But the most impressive part of my results came after I took into account that although the Friday outdoor afternoon temperature reached about 79 degrees, the outdoor temperatures dipped into the 40's during the overnight hours. Initially, I was convinced that the overnight temperatures were going to wipe out any of the gains the heater made during the day on Friday, but when checking the heater at 6am Saturday, I saw that although the temperature didn't rise at all overnight, the heater was able to maintain the temperature overnight and didn't lose any ground. Since then I have set the heater and pump on a 12 hour timer, and the heater has maintained the pool at 83 degrees afternoon temperature, even though the weather conditions in New Jersey are not always ideal at this time of the year (early June).
P.S. The unit that is currently pictured on Amazons site, is not the correct picture of the HP21404T. Check Hayward's site for the correct picture. It closely resembles the Hayward Summit units. In fact, it seems almost identical to the Summit units except it is a different more attractive color in my opinion, and also has the spa feature (which does not apply to my spa-less pool). Also the unit is 140000 BTU's, not 14000 stated in the description. Would definitely recommend this unit based on it's initial performance and overall quality feel to the unit.

Very Easy to Install and the Cost was Considerably Less Than
We owned this brand before. It lasted 5 years until a lightening strike to the ground took it out. Hook up was easy. It came with all the necessary parts to hook it up to our existing sand filter. Our 1st one was only a 1HP but wanted one that cycled a little faster since we live in the country and have a lot of dust/dirt blowing all the time. It seems to keep the pool cleaner. Priced them from pool stores and they were significantly higher in price.
This was a replacement for an identical 10 year old pump. Very easy to install and the cost was considerably less than two pool companies quoted for repair or replacement.
