ECOPOOLTECH 16,000 BTU Pool Heat Pump
Priced out: the small-pool unit that now costs the most — ECOPOOLTECH's EU50: a 16,000 BTU plug-in heat pump for the smallest above-ground pools (up to ~5,000 gallons) on a standard 120V outlet. It was this tier's price floor until a September re-list moved it inside ECOPOOLTECH's Ultra Inverter family at about $799, where it costs more than every other unit here and shares its 4.2★/288 with inverters up to 26,000 gallons

Pros
- A true 120V plug-in sized for pools up to about 5,000 gallons — no electrician, no 220V circuit
- Longer stated coverage than most no-names — 3-year support plus lifetime technical assistance, which the September listing now calls a 3-year warranty
- Efficiency claim up to COP 5.6 — a lot of heat per kWh
Cons
- Re-listed in September at about $799 — now the most expensive unit in this tier, for the smallest capacity
- Smallest capacity in the roundup (≤~5,000 gal) — the September listing's title says 7,000 gallons while its own bullet says 5,000; go by the 5,000, and undersize your pool and it never keeps up
- The 4.2★/288 rating is shared across ECOPOOLTECH's whole Ultra Inverter family, up to 26,000-gallon inverters, so it says little about this small unit
- Instructions are picture-only — owners get there, but expect a puzzle
“Really the only negative thing about this pool heater was that the directions were a bit confusing. They’re all pictures- no words- but we were able to figure it out! This has (so far) kept our water at 80+ degrees (F) since about day 2 or 3 of having it turned on. We have an 18ft pool which sits in a very shaded yard…”— Katie, Amazon · Verified owner

Who is the ECOPOOLTECH 16,000 BTU Pool Heat Pump for?
You have a genuinely small above-ground pool (≤~5,000 gal) and ECOPOOLTECH's stated 3-year window matters more to you than the Aquastrong belt's cooling mode and lower price — at about $799 that is the only case for it.
