My business partner Jim got an email this week from a previous inground customer that gave me a little grin, mainly because it is such a perfect representation of a conversation we have when talking to potential customers the first time regarding Heat Pumps:
Dear Jim,
We know that we balked when you told us that we needed a chiller for our pool. We could not imagine the water ever getting so warm that we would require such a thing (and it kinda seemed like a waste of money, to be honest). We are here to testify that without that chiller over the last week of 90 degree plus days, every single day here in Northern Virginia, we could/would not have been able to use our pool. When the water temp finally hit near 90 degrees last weekend, Cynthia said, "Let's give that chiller a shot". What a lifesaver! Instead of getting in what felt like pretty un-refreshing bathwater, since then, the chiller has kept the water temp at a manageable and refreshing 84 degrees. Feel free to have anyone who is on the fence regarding chillers just give us a call - we'll more than endorse them.

A special thanks to Scott for taking the time to write this note that addresses the question of whether to get a regular heat pump vs. one with a chiller.
Why is my pool water so hot, and how can I cool it down?
Your pool water will likely get too warm in the summer if it's 6 feet deep or shallower and if it receives a lot of sunlight. One way to keep the pool at a good temperature is to use a chiller. A heat pump with a chiller function allows you to keep your water refreshing even in midsummer heat.
Is a chiller even necessary?
I'm always amazed when I speak to a customer that has received 2 or 3 quotes from other pool companies and no one has yet mentioned the potential need to cool the pool water as well.
Frankly, when I see such a lack of teaching from other pool guys, I want to slap my forehead and the first thought that comes to my head is:
Are you kidding me??
Here's the deal: If your pool is 6' or less in depth and receives good amounts of sunlight throughout the day, then you'll likely have need for a chiller at some time or another (obviously depending on your region).
If you follow that advice, I promise you that you'll make the right decision as to whether to go chiller or not with your heat pump purchase.
As always, happy swimming to everyone in this blistering weather!
