How to choose
Match output to pool size
Start from the pool size each maker gives: 7,000 gallons for the Varpoolfaye, 5,200 gallons for the NATURAQUELL, and 10,000 gallons for the WARMBLU. Compare those figures with the pool in question, then look at heat output: 30,000 BTU, 18,000 BTU, and 35,000 BTU in the same order. A larger pool needs a larger output figure to hold temperature through the season.
Heating and cooling modes
All three picks heat and cool: the Varpoolfaye runs heating from 46°F to 104°F and cooling from 46°F to 82°F. A cooling mode matters when summer water runs warmer than wanted, since it lets the same unit bring the temperature back down. Check the heating and cooling ranges before buying, since a unit without a stated cooling range cannot be assumed to cool.
Controls, cords and upkeep
The Varpoolfaye and NATURAQUELL offer WiFi app control. The NATURAQUELL and WARMBLU add a touch panel. The Varpoolfaye setup uses 1.5 inch connectors and a 126 inch power cord, so check connector size and cord reach before ordering. A pool cover can improve heating efficiency, and condensation from heat exchange and defrosting is normal.
