Stoves, fireplaces, pellet burners
Ash is fine, abrasive and occasionally still alight, which is why a household vacuum does not survive it and a workshop vacuum is not safe with it. A proper ash vacuum has a metal drum, a metal hose end and a filter arranged so embers cannot reach it. We compare construction, filter cleaning and capacity — and say plainly which machines are aluminium-look plastic.
800 W · 170 mbar · 18 l steel drum · aluminium tube
Eighteen litres of tinplate and an aluminium tube, at the price of a cheap household vacuum.
Best for: An occasional fire or a pellet stove, where the vacuum is used a few times a month
≈ 58 €
14 l metal drum · filter cleaning · cold ash only
A metal drum and a filter you can shake clear — the minimum a fireplace vacuum has to be.
Best for: One fireplace or pellet stove, cleaned regularly, where the vacuum lives beside the hearth
≈ 120 €
850 W · 175 mbar · 20 l steel drum · aluminium hose
The 1830 with a metal hose and two more litres — and the metal hose is the upgrade that counts.
Best for: Regular winter use on a wood burner, where the machine is emptied often and the hose sees warm surfaces
≈ £65 / 62 €
15 l steel drum · HEPA in a metal housing · warm ash to 40 °C
A HEPA filter in a metal housing, and a manufacturer that publishes an actual temperature limit.
Best for: A single stove or fireplace, cleaned often, where a small machine that lives beside the hearth is the point
≈ 40 €
1 650 W · 20 l metal drum · HEPA plus reusable bag filter
The most powerful ash vacuum here, with two filter stages and a four-metre cable.
Best for: Open fires and larger fireboxes, where a 15-litre drum would need emptying mid-job
≈ 50 €
Flame-retardant body · antistatic handle · bagless · 1.7 m hose
Flame-retardant material and an antistatic handle: the ash vacuum that takes its own hazard seriously.
Best for: A household that empties a wood burner or pellet stove every week through the winter
≈ 130 €
The capacity decides how many times you empty over a heating season, and a drum full of ash weighs more than it looks.
What stops the ash coming back out is the quality of the filtration, and the power available to keep the airflow up as the filter loads.
A few fires a winter do not justify a big machine; the most affordable model in the aisle does the job.
Only if the manufacturer says so, and only warm. An ember in a drum full of ash can smoulder for several hours before igniting, metal drum included.
Ash is abrasive and so fine that it passes through an ordinary filter, settles on the motor and comes back out into the room. That is a short-term failure and immediate indoor pollution.
At almost every use. An ash filter loads within minutes and the suction halves long before the drum is full.
It helps if someone in the household is sensitive to fine particles. For ordinary use, a well-maintained metal filter and a pre-filter are enough.
At least twenty-four hours for an insert, longer for a full open fireplace. Doubt is settled by stirring the ash: the slightest glow means waiting.
Yes, it is the same need. The only difference is the volume, generally smaller, so a small drum is enough.
It makes the difference between a forgiving machine and one that melts. On plastic-hose models, the completely cold ash rule is not negotiable.
An insert used daily gives two to three litres of ash a week. A fifteen-litre drum is emptied once a month, a five-litre one every week.
An ash vacuum is judged on filtration and materials, not on watts. A washable filter, a metal drum and hose, and the discipline of waiting until the hearth is cold: that is all that separates a machine that lasts from an incident.
A figure has to be published by four machines in five to earn its column. Below that, we would be comparing empty cells.
