VARMINPOOL V5 16,000 BTU Pool Heat Pump
One to watch: a family average, not this machine — VARMINPOOL's V5: a 16,000 BTU, 120V WiFi heat pump the maker rates for above-ground pools up to 5,400 gallons, about $700 — sold on Amazon as one size of a 13-size VARMINPOOL parent under titles that claim 18,450 BTU and 6,300 gallons, and the only rating on it is the whole line's pooled 4.5★

Pros
- A 120V plug-in with a WiFi app; owners have repeatedly called out easy install and responsive tech support
- Titanium heat exchanger (maker-stated)
Cons
- The 4.5★/198 it shows is the whole VARMINPOOL line's, pooled across 13 sizes from this plug-in up to the 140K V35 Ultra, with Vine and non-US reviews in it — nothing on the page rates this machine on its own
- Amazon titles in this family say 18,450 BTU and 6,300 gallons; VARMINPOOL's own store rates this unit (the V5, KSPF-005) at 16,000 BTU for up to 5,400 gallons, and a sibling listing's own spec line says 16,000 too — plan on the maker's figures
- No stated manufacturer warranty, and the maker's store has the V5 sold out
- A few owners report the unit freezing up / not heating in cold air — the heat-pump ~50°F floor, not a defect
Freezing up and refusing to heat in cold weather — which is the roughly 50F heat-pump floor rather than a fault, and applies to every heat pump on the page.

“I'm very satisfied with this purchase. The installation was simple, and the heater started working without any issues. In my above-ground pool of approximately 6,000 gallons, it keeps the water at a very comfortable temperature while using very little electricity.”— Jesus gonzales, Amazon · Verified owner

Record
- — Read 2026-09-24 of B0F6V8JVKR and its sibling B0H9KFJC9V: both read 4.4★ across 153, identical, so the base is pooled across a 13-size parent (10x20 ft to 22x44 ft pools, $619.99 to about $1,499); 2 free-product (Amazon Vine) reviews and Canadian and Mexican cards among 13. Our listing is the 10x20x49 in size, titled '6300 Gallons Pool Heater for Above Ground Pool,110V, Pro', $699.99. Our listed rating moved from 5/3 to 4.4★ across 153.
- — Price read $699.99 on B0F6V8JVKR (we had listed $629.99); rating now shows the pooled line-wide 4.4★ across 153.
- — Renamed from "VARMINPOOL 18,450 BTU Pool Heat Pump" to the maker's V5 16,000 BTU. VARMINPOOL's store lists KSPF-005 as the V5, 16,000 BTU, up to 5,400 gallons; the sibling Amazon listing B0H9KFJC9V's bullet reads "KSPF-005L3R1A1 model with 16,000 BTU heating" (A1 is the model on the listing we link). 18,450 BTU and 6,300 gallons appear only in Amazon titles and listing copy.
- — The 4.4★ across 85 owner base vanished from the listing in a re-list that reset reviews (same title, same price, 5.0★ across 3). Demoted from best value to a watch; no fault found with the machine, its evidence was gone.
