Where this leaves you This is a portable air conditioner with a heat mode, not a convector panel — and it publishes both its cooling ratings, 8,000 BTU ASHRAE and 5,000 BTU DOE. Judge it against the air conditioners, not against a wall panel.
Seven products here are convection panels and convector heaters: no compressor, no hose, no window. This one is an air conditioner that can also warm a room.
If you want heat, the panels on this shelf publish wattages you can compare. If you want cooling, this is the only product here that does it, and the window air conditioner shelf is where it should be judged.
The honest pair of numbers
Eight thousand ASHRAE, five thousand DOE. That gap — thirty-seven per cent — is what a hose costs a portable, and most listings in the category print only the first figure.

The good and the less good
Strengths
Publishes both cooling ratings — 8,000 BTU ASHRAE and 5,000 BTU DOE — which is the honest way to describe a portable
Four modes in one body, including a dehumidifier, so one machine covers summer and the shoulder seasons
Publishes an airflow figure in cubic meters per hour and a wattage, both of which most of this shelf omits
Compromises
Not a convector: it is a compressor machine with a hose, and it takes a window
Its heater mode has no published output, so there is no way to compare it with the panels on this shelf
The heaviest and bulkiest thing here by a wide margin

The questions that keep coming up
Can it replace a panel heater?
Not sensibly. It is a portable air conditioner whose fourth mode is heat, and the listing publishes no heating output at all. Seven heaters on this shelf publish a wattage; this one publishes 880 W as its power draw, which is a different thing from its heat output in heater mode.
Why two BTU figures?
ASHRAE measures the cooling produced; DOE accounts for the heat the hose returns to the room. 8,000 and 5,000 is a 37 per cent gap, and publishing both is candid — many portables print only the larger figure.
Does the heater mode use the compressor?
The listing does not say. What it does publish is R32 refrigerant and a four-mode selector including heat, which usually means a reversing heat pump — but this page will not assert a mechanism the maker has not described.

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 m (33 ft)² 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 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 m (49 ft)², 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.
