envflame is a rechargeable insert for existing log-burning stoves. It recreates the glow and movement of a real fire—without the PM2.5 pollution. A practical pathway for cleaner neighbourhoods, healthier homes, and happier residents.
Demonstration of the envflame 'zephyr' cartridge operating inside a standard log-burning stove (no combustion, zero indoor smoke).
The following figures are taken from our briefing text and public discourse. We will work with partners to validate and localise these figures during pilot design.
Fine particulate matter small enough to enter the bloodstream; associated with cancer, strokes, and asthma.
Only 8% of English households use log burners, yet they account for 17% of national PM2.5 emissions.
A single log burner can be up to 750× more polluting than an HGV, by PM2.5 per unit energy used.
Pair envflame with local clean air programmes, school streets, and public health initiatives. Offer targeted vouchers or trade‑in schemes to households using stoves for ambience.
A realistic flame visual produced by the envflame insert — ambience retained, PM2.5 eliminated at source.
Modelled reduction proportional to participating households, with validation via local sensors.
Lower exposure risk for children, the elderly, and those with asthma — aligned to ICS & public health targets.
A positive alternative to outright bans: preserve ambience, improve air — fewer complaints, faster adoption.
Select pilot wards, help recruit households, enable data collection, and co‑shape the adoption incentives.
Provide hardware, installation guidance, resident comms, and rigorous monitoring & evaluation — in partnership with your teams.
We’re currently raising capital to scale manufacturing and reduce unit cost for mass adoption. Let’s co‑design a pilot that fits your borough’s clean‑air strategy.
Councils, combined authorities, and public health teams: we’d love to share the pilot blueprint and evaluation templates. Please include your borough and team in the message.
