Pros
- A real US brand with a warranty behind it — the white-label rivals in this tier offer none
- The rare 35K unit that runs on a standard 120V outlet, so no electrician for a mid-size above-ground pool
- Cleanest owner base in the tier (4.2★/93, 0 Vine) — owners routinely return cheaper Chinese imports for it
Cons
- Pricier than the white-label rivals (about $1,299 vs ~$1,099–$1,199)
- Heat only — it doesn't cool
- The 10-year warranty is mostly prorated: one year of full parts and labor, then it pays half the part cost in years 2–5 and a quarter after that, with shipping to the repair center on you
Damaged on arrival or failing early — fan blades, a leak at two weeks, a controller one owner says is not rated for outdoors — and then support goes quiet. Returning a heavy unit costs hundreds.

“I ordered a similar heater that was from China and 1/3 the price of this one, but it stayed on for about 10 minutes, shut down and wouldn't restart. I returned the Chinese one and got this — glad I did.”— K. E., Amazon · Verified owner
FAQ
Who is the FibroPool FH135 Pool Heat Pump (35K BTU) for?
You want a mid-size-pool heat pump from a real brand with a warranty — and you'd rather not hire an electrician, since it's the rare 35K unit that runs on a standard 120V outlet.
What do owners say about the FibroPool FH135 Pool Heat Pump (35K BTU)?
4.2★ across 93 owner ratings (Amazon, read September 2026 · early data). What owners complain about: Damaged on arrival or failing early — fan blades, a leak at two weeks, a controller one owner says is not rated for outdoors — and then support goes quiet. Returning a heavy unit costs hundreds.
Who sells the FibroPool FH135 Pool Heat Pump (35K BTU) on Amazon, and can it be returned?
Sold by FibroPool USA, shipped by Amazon, when we read the listing on 2026-10-08. Amazon's returns line read: 30-day refund / replacement. Sellers and return terms can change, so check both on the listing before you buy.
What is the warranty on the FibroPool FH135 Pool Heat Pump (35K BTU)?
10-yr limited (1-yr full parts + labor, then prorated)
Does the FibroPool FH135 Pool Heat Pump (35K BTU) warranty still apply if I buy it on Amazon?
Yes as far as the document goes: FibroPool's warranty carries no authorized-dealer, unauthorized-reseller or marketplace condition — we checked the full text on 2026-09-14. That is unusual in outdoor gear, where the multi-year term is often attached to the dealer channel rather than the product.
Record
- — Re-read: 4.2 across 93 ratings (was 4.1 across 92). The listing's size selector also offers the 55K and 70K, but each carries its own count and star spread, so this rating is the 35K's own.
- — Warranty now read from FibroPool's heat-pump warranty, which its product page links, instead of the general one that excludes heat pumps: a limited 10-year term with one year of full parts and labor, then prorated parts. The lifetime titanium-tubing clause in that document is not carried here, because FibroPool does not say this model has a titanium exchanger.
- — Review base checked and clean: 4.1 across 92 on a single-model listing with no free-product (Amazon Vine) reviews. It holds the Middleweight belt on that composition plus a brand warranty that survives an online purchase, not on the star average.
- — Heat exchanger material not published by the maker. Critical pass the same day: damaged on arrival or failing early — fan blades, a leak at two weeks, a controller one owner says is not rated for outdoors — and support then goes quiet. Returns are the recurring second half of that story.
- — Checked FibroPool own Shopify catalogue, not just this model: not one unit in the FH line — FH120, FH135, FH220, FH255, FH270, FH235-i, FH285-i — carries a flow figure in its catalogue entry. FibroPool sells a bypass assembly and a replacement flow switch for these same heat pumps, so flow plainly matters to the install, and the catalogue still states none. Recorded as published-nothing at that source; the owner manuals were not read, which is the gap that turned out to matter on a rival.
