Noirot Radiaflo review
A 1 000 W electric radiator using fluid thermal inertia — Noirot heats mineral oil with an immersion resistance, so the unit keeps radiating stored warmth after the element cuts out. It carries free daily and weekly programming, a window-open detector, a parental lock, Origine France Garantie and NF certification, and Noirot states it was voted 'Product of the Year 2024' in France. It's the most expensive heater in this family, and we could only confirm a live offer on one of the six markets we checked.
The bottom line The most capable and most expensive heater in this family — genuine fluid inertia, full programming, and real French certification — but currently a France-only purchase, and worth the premium only if you're not planning to shop around outside that market.
A different inertia mechanism than the Bestherm ALBA
The Radiaflo doesn’t use a ceramic core — Noirot heats mineral oil inside the unit with an immersion resistance, and states that the oil keeps radiating stored warmth after the element switches off. That’s the same broad idea as the ceramic dry-inertia core in the Bestherm ALBA reviewed alongside it, but through a liquid medium rather than a solid one. Noirot doesn’t publish a side-by-side comparison against ceramic designs, and neither do we — we’re reporting what each manufacturer states about its own mechanism rather than ranking the two.
Genuinely free programming
Noirot’s own copy states free daily and weekly programming, alongside a window-open detector that cuts the unit’s output on a sudden temperature drop, and a parental lock to stop the schedule being changed accidentally. Compared with the Bestherm ALBA’s 3 pre-loaded programs plus one custom slot, Noirot’s “free” framing suggests more flexibility in setting up a schedule, though the exact interface isn’t detailed in the product copy we could access.
Certification claims worth taking seriously
This is the one heater in the family with third-party-style claims attached rather than just manufacturer marketing language: Origine France Garantie (a French label certifying domestic manufacture), NF certification (a recognised French safety and quality standard), and Noirot’s own statement that the Radiaflo was voted “Produit de l’année 2024” in France. We can’t independently verify the award claim, but Origine France Garantie and NF are both established, checkable certifications rather than invented marketing terms.
A dimension discrepancy we’re not resolving
Noirot’s own spec sheet for the 1 000 W unit states 49 × 58.3 × 13 cm and 12.15 kg net. Amazon’s separate package-logistics data for the same ASIN shows a noticeably lighter and differently-shaped box. This is a common gap between a manufacturer’s product-only figures and a marketplace’s shipping-box data, and rather than silently pick the number that sounds more precise, we’re reporting both and flagging that we can’t resolve it from the data available.
Running cost, without guessing at electricity prices
At 1 000 W, one hour of continuous full-power use draws 1 kWh. As with the Bestherm ALBA, the stated inertia behaviour means real-world average draw over an evening will typically sit below that figure once the unit reaches temperature, but we’re not putting a percentage on that saving without Noirot publishing one itself. Multiply your own electricity tariff by your actual hours of use for a real number.
Where we found it in stock
We queried Amazon.com (US), Amazon.co.uk (GB), Amazon.de (DE), Amazon.fr (FR), Amazon.it (IT), and Amazon.es (ES) through Keepa’s product API. ASIN B0CJ9XHM88 carried a live offer, at roughly 310 €, only on Amazon.fr. On DE, IT, ES, US, and GB, the same ASIN exists in the catalog with a matching title and EAN, but had zero live offers at the time we checked — no price, no seller. We’re reporting this as an FR-only purchase rather than listing prices for markets where it currently isn’t actually for sale.

What we like, and what we don't
Strengths
The only fluid-inertia radiator in this family — mineral oil retains and releases heat differently than the ceramic dry-inertia core in the Bestherm ALBA reviewed alongside it
Free daily and weekly programming is more flexible than the Bestherm's 3-preset system
Origine France Garantie, NF certification, and a stated "Produit de l'année 2024" award are concrete, checkable claims rather than vague quality language
Parental lock is explicitly named alongside the window-open detector
Compromises
Confirmed for sale on only one of the six markets we checked (FR) — the identical ASIN exists with a matching title and EAN on DE, IT, ES, US, and GB, but carried zero live offers on any of them at check time
By far the most expensive heater in this family, at roughly 310 € — more than four times the Bestherm ALBA's lowest confirmed price
Noirot's own stated dimensions and weight for the unit don't match Amazon's separate package-logistics data, and we can't resolve which set is more accurate
At over 12 kg net for the smallest (1 000 W) version, this is the heaviest single item in the family — installation is more involved than hanging a light convector
Specifications
Power
1 000 W (this ASIN; Noirot also sells the Radiaflo line at 1 500 W and 2 000 W under separate listings)
Heating type
Fluid thermal inertia — mineral oil heated by an immersion resistance, per Noirot; continues radiating after the element switches off
Programming
Free daily and weekly programming, per Noirot
Safety
Window-open detector (auto shutoff on a sudden temperature drop) + parental lock, per Noirot

Questions people actually ask
Is the Radiaflo sold outside France?
Not that we could confirm. The ASIN B0CJ9XHM88 exists in Amazon's catalog on Germany, Italy, Spain, the US, and the UK, with a title and EAN that match the French listing — but at the time we checked, none of those five markets carried an actual seller offer. We're treating it as an FR-only purchase for now rather than assuming it will restock elsewhere.
How does fluid inertia compare to the ceramic dry inertia in the Bestherm ALBA?
We're not going to make a physics claim neither manufacturer backs with comparable data. What we can report is what each states: Bestherm describes a ceramic core that keeps radiating after the element switches off; Noirot describes mineral oil heated by an immersion resistance doing the same thing through a liquid medium rather than a solid one. Both are real, established inertia designs — we don't have the data to say one runs warmer for longer than the other.
Why do the dimensions in the spec sheet not match the package size?
Noirot's own copy states the unit itself measures 49 × 58.3 × 13 cm and weighs 12.15 kg net. Amazon's separate package-logistics data — which usually reflects the shipping box, not the product — shows a lighter, differently-proportioned box. That's a common discrepancy between manufacturer product specs and marketplace shipping data, and we're reporting both rather than picking one as correct.
Our score
8.1/ 10
The most capable and most expensive heater in this family — genuine fluid inertia, full programming, and real French certification — but currently a France-only purchase, and worth the premium only if you're not planning to shop around outside that market.
Who this one is for
Someone in France specifically who wants a French-made, NF-certified fluid-inertia radiator with full daily and weekly programming, and is fine paying a real premium for it.

2 000 W · 3 heat settings · natural convection, no fan
A basic 2 000 W electric convector with three heat settings — 750 W, 1 250 W, and a 2 000 W 'Turbo' stage — controlled by an adjustable thermostat dial. Alpina describes pure natural convection with no fan, rates it for rooms up to 15 m², and states overheat protection. It's the cheapest heater in this family, but one of the four markets we checked shows a data problem worth knowing about before you buy.
Best for: The cheapest way into this family — a small room, workshop, or occasional-use space where basic convection heat at low upfront cost matters more than programming or thermal inertia.
A wall-mounted 1 000 W electric radiator built around a ceramic dry-inertia core — Bestherm states it keeps diffusing stored heat after the element switches off, unlike a plain convector. Programming runs through a touch LCD screen with 3 pre-loaded weekly programs plus 1 custom program, and the unit supports France's 6-order Fil Pilote wired protocol. Bestherm also states a window-open detector, child lock, overheat protection, and a 2-year warranty with France-based support.
Best for: A single room around 10 m² where scheduled inertia heat is worth the step up from a plain convector — especially if your home already has French Fil Pilote wiring to plug it into.
2 000 W · 3 power levels · manual thermostat, no fan
A 2 000 W electric convector from De'Longhi with three power levels — 750 W, 1 500 W, and 2 000 W — a manual thermostat knob, and an automatic antifreeze function that switches on below roughly 5 °C. De'Longhi rates it for rooms up to 60 m³, states a safety thermostat and double insulation, and builds in a carry handle for moving it between rooms. There's no programmable schedule and no digital display.
Best for: A medium-sized room up to 60 m³ where you want an established heating brand's straightforward convector without needing weekly programming.
