WOPOLTOP 100K BTU Pool Heat Pump (Heat & Cool)
Most BTU per dollar for a mid-large pool — no warranty, read the catch — A 100,000 BTU full-DC-inverter reversible (heat AND cool) unit for in-ground pools up to 26,000 gallons — the most heating power per dollar in the field, on the cleanest white-label owner base (4.1★/30 mostly model-specific). The honest catch is the whole white-label story: an ABS-plastic case, no stated warranty, and a real thread of owners whose unit died after one season with support nowhere to be found. Buy it for the price and the BTU, eyes open.

Pros
- Most heating power per dollar — 100,000 BTU, heat + cool, about $2,460
- Cleanest base of the big white-labels (4.1★/30, mostly model-specific rather than pooled)
- Genuinely quiet; owners heat a 15,000-gal pool from the mid-60s to 90°F in a couple of days
Cons
- ABS-plastic case and no stated warranty
- A real cluster of owners report the unit dead coming out of its first winter, with support impossible to reach
- You're self-insuring a $2,460 purchase — the price of no warranty
Completely dead after one season, with no support reachable — the textbook white-label failure, on a unit whose whole case is the price.
the dominant critical card; a single card, but on a no-warranty white-label it is the risk the price is buying · critical reviews read August 2026
“This product is pretty awesome. It's way quieter than my old unit. Like whisper quiet. It seems to heat well I have a 15,000 gallon pool and within a couple days it brought it from 65° to 90. You probably still need a solar cover. It seems to be well-made.”— Mike M., Amazon · Verified owner
