VonHaus Stove Fan Review: '6 Blades' Means Two Heads of 3
This VonHaus stove fan review covers the 6 Blade Double Stove Fan, the twin-headed heat-powered fan VonHaus sells on its own website and on Amazon UK. On paper it is a strong budget pick: it starts at 50°C, claims 200 CFM of airflow, runs up to 345°C and comes with a two-year warranty that needs no registration. Look closer and the “6 blades” are two fan heads of three blades each, and nothing in the listing or the manual mentions overheat protection. Both points change who should buy it.
We have read the VonHaus product page, its instruction manual (document 2500886) and the Amazon UK listing, and compared them with the fans in our stove fan comparison. This is a desk review, not a lab test. All figures were checked on 9 October 2026.

What “6 blade double” actually means
The name suggests more blades than you get. VonHaus’s own page talks about “two sets of six blades”, while the Amazon UK listing says “the 6 aluminium blades”. The product photographs settle it: two fan heads side by side, each with three blades, for six in total.
That is not a defect. A twin-head fan spreads air in two directions, which helps on a wide stove or one set into a recess where a single forward jet hits the back of the fireplace. But do not compare it with a 6-blade single-head fan as if it had twice the blades. Blade count is a weak guide to airflow in any case; blade shape, size and motor speed matter more.
The specs: strong start, high ceiling, no stated safety lift
50°C start. This is as low as any mainstream fan we cover and matches the Valiant Premium IV. A fan that starts at 50°C begins moving air soon after lighting and keeps going as the stove cools, which suits smaller stoves and gentle burns. The budget VODA starts at about 80 to 85°C by its listings, and the Ecofan AirMax at 85°C.
345°C top limit. VonHaus’s manual warns that the product “operates between the temperatures of 50ºC - 345ºC” and that higher temperatures can damage it. That ceiling is higher than the Valiant’s 300°C and matches the Ecofan AirMax.
No overheat lift that we can find. The Valiant Premium IV and the VODA both have a bimetal strip that tilts the fan off the hot surface at about 250°C to protect the thermoelectric module. Neither the VonHaus listing nor its manual mentions one. That makes the 345°C ceiling a limit you have to police yourself. Run this fan with a stove thermometer beside it, and take it off if the stove top heads towards 300°C.
200 CFM. As with every heat-powered fan, there is no test method behind the airflow figure, so do not use it to rank fans against each other. It is higher than the Ecofan AirMax’s 175 CFM on paper, which tells you little in practice.
How it compares
| VonHaus 6-blade double | Valiant Premium IV | VODA 4-blade | Ecofan AirMax | |
|---|---|---|---|---|
| Heads and blades | 2 heads, 3 blades each | 1 head, 4 blades | 1 head, 4 blades | 1 head, 2 blades |
| Starts at | 50°C | about 50°C | about 80 to 85°C | 85°C |
| Upper limit | 345°C | 300°C | about 250°C lift | 345°C |
| Overheat lift | Not stated | Yes, above 250°C | Yes, about 250°C | Not stated in its spec |
| Claimed airflow | 200 CFM | Not published | 240 CFM | 175 CFM (tested) |
The Valiant is the closest rival: the same low start and a built-in safety lift, which matters if your stove top runs hot. Our Valiant Premium IV review has the detail. The VODA is usually the cheapest of the three and has a far bigger ratings base, but needs a hotter stove to start; see our VODA stove fan review. The Ecofan AirMax, from the Canadian company Caframo, is the premium option with a standards-tested airflow figure and a replacement motor kit; see our Ecofan AirMax review.
What owners say
On Amazon UK the listing had 152 ratings averaging 4.4 stars when we checked, with 71% five-star and 6% one-star. Amazon’s summary says buyers like how well it performs and moves warm air around the room. On VonHaus’s own site it had 51 reviews averaging 4.9, with comments such as “very quiet” and “great at pushing the heat around”. One owner says they run two fans on one stove.
That is a much smaller sample than the VODA’s 13,000-plus ratings, so it says less about long-term reliability. With budget heat-powered fans, failures usually show up after a season or two, and the usual cause is a module cooked by too much heat. On a fan with no stated overheat lift, that is the risk to manage.
Getting the best from it
- Keep it away from the flue. The manual says to position the fan “as far away from the flue pipe as possible” and not directly in front of it. Set it towards the back corner of the stove top on the side away from the flue collar.
- Use a thermometer. Keep a magnetic stove thermometer next to the fan. In normal burning the stove top should stay comfortably below 345°C; if it climbs past 300°C, lift the fan off with its handle.
- Do not leave it running unattended. The manual says so explicitly, so take it off before you go out or go to bed with the stove still hot.
- Carry it by the handle. The base and fins get very hot. The manual also warns that dropping it can damage the circuit board and blades.
- Clean it cold. VonHaus says to dust the blades and fins with a soft cloth once fan and stove are completely cool, and to avoid water or chemicals.
- Not for every heater. VonHaus says it is not compatible with electric stove heaters, and its FAQ does not recommend gas stoves or open fires.

Who should buy the VonHaus double fan
Buy it if you have a wide stove or a recessed fireplace where air pushed in two directions helps, you run moderate burns, you want a fan that starts early on a cooler stove, and you value a UK brand’s two-year warranty without registration.
Look elsewhere if your stove often runs hot and you want a fan that protects itself (the Valiant Premium IV lifts itself above 250°C), or if you want the reassurance of a very large owner base or replaceable parts.
Frequently asked questions
Is the VonHaus stove fan any good? It looks good value on paper: a 50°C start, a 345°C limit, 200 CFM claimed and a two-year warranty. It had 152 Amazon UK ratings averaging 4.4 stars in October 2026. The main caveat is that VonHaus does not mention overheat protection, so you need to watch the stove temperature yourself.
How many blades does the VonHaus double stove fan have? Six in total, on two fan heads of three blades each. VonHaus’s own page describes “two sets of six blades”, but the Amazon listing says six aluminium blades and the product photos show three per head.
What temperature does the VonHaus stove fan start at? About 50°C on the stove top, according to VonHaus. It speeds up as the stove heats and slows as it cools.
What is the maximum temperature for the VonHaus stove fan? 345°C. The manual warns that higher temperatures can damage it. Because no overheat lift is mentioned, use a thermometer and take the fan off well before that point.
Do I need to register the VonHaus warranty? No. VonHaus says the two-year warranty is included and starts from the date of purchase, with no registration needed.
Can I use the VonHaus fan on a gas or electric stove? VonHaus says it is not compatible with electric stove heaters, and its FAQ says stove fans are not recommended for gas stoves or open fires. It is designed for wood-burning and multi-fuel stoves.
