Installing smokeless stoves for cleaner indoor air

Smoke from an open cooking fire is a familiar part of daily life in many Nepali homes. Fine particles, carbon monoxide and heat can remain in a kitchen long after a pot has boiled, making the room uncomfortable and unsafe for children, older relatives and anyone breathing nearby.

A successful smokeless stove installation begins with the household rather than a product. The installer learns how food is prepared, which fuels are affordable, how many people cook and where the family can safely place a stove and chimney.

For Australian supporters, the issue is recognisable: Melbourne residents routinely deal with bushfire smoke, while kitchens here often use gas cooktops or electric induction. A cylinder of liquefied petroleum gas is commonly called bottle gas, but many rural homes still rely on wood for heat.

The need is also reflected in Nepal's wider housing conditions. Families affected by earthquakes, landslides or poverty may live in temporary shelters with little ventilation. Replacing an open fire with a properly installed, maintained stove can improve air quality while making daily cooking more efficient.

Why smoke is a household health risk

Burning wood or charcoal in an open fire releases fine particulate matter, including particles small enough to enter the lungs. The same combustion can produce carbon monoxide, especially in a poorly ventilated room. People who cook or spend time near the stove may experience eye irritation, headaches, coughs and breathing difficulties.

Children and pregnant women face particular risks from prolonged exposure, while older people with heart or lung conditions can be affected more quickly. Cleaner cooking is therefore part of public health, not simply a household comfort. A smokeless model reduces smoke, but ventilation, sound operation and regular maintenance still determine how much pollution remains.

What the stove actually changes

A typical improved stove encloses the fire in a combustion chamber. Carefully sized openings admit air, while an upper cooking surface holds one or more pots. A flue or chimney draws smoke outside, and a removable ash tray keeps waste under control. The design concentrates heat rather than allowing it to escape around an open flame.

Good design can also reduce fuel use because less heat is lost to the room. A steadier flame gives cooks more control over simmering dhal bhat or heating a kettle. These gains depend on correct dimensions, a sound chimney and suitable fuel; an ill-fitted stove can smoke badly or create a new indoor hazard.

Assessing the home and cooking routine

The first visit should map the cooking routine. The technician asks what is cooked, how long meals take, who tends the fire and whether more than one pot is used at once. The assessor checks floor strength, wall stability, roof design, nearby openings, ventilation and the safest route for a flue. Available firewood and agricultural residues are tested for moisture, because wet fuel produces heavy smoke.

For a charity such as One Home Foundation, this careful assessment supports a wider mission of safe, resilient and affordable housing. Its work with the Chepang community, disaster-affected families, shelter construction, integrated settlements and health facilities creates opportunities to link improved kitchens with secure homes and preventive care. Local masons and technicians should be involved from the outset so the stove matches local buildings and skills.

Installing the stove and flue

Preparation comes before construction. The crew clears a safe area, protects the floor from heat and embeds the stove base securely. Dimensions are checked against the pots and the room, while drainage and weatherproofing are considered in monsoon-prone areas. Earthquake-resistant bracing or a freestanding flue may be needed where masonry cannot be anchored safely.

The combustion chamber, cooking surface, ash outlet and chimney are then assembled or built. The chimney must maintain a steady draft without coming too close to a thatched roof or timber eaves. Experienced local craftspeople reduce the risk of cracks, loose joints and poor seals. Vents should lead outdoors, never into a roof space or neighbouring room.

Commissioning is the final stage. A technician lights a small fire and checks airflow, flame behaviour, smoke leakage, stability and draft. Several test meals reveal whether the pot supports work correctly and whether the cook can reach the fuel and ash safely. The household receives practical instruction on starting, extinguishing, cleaning and responding to a poor draft before the installer leaves.

Keeping the system safe

Maintenance is where many apparent stove failures begin. Fuel should be kept dry, vents and cooking holes should be cleared of ash, and the chimney should be inspected for soot or blockages. Cracked masonry, loose joints and a damaged flue need prompt repair. Good ventilation remains important, even with a working chimney.

A local repair network makes these checks sustainable. Trained technicians can train household members, supply small parts and report recurring design problems to the project. Feedback from cooks helps organisers refine stove size, chimney height and fuel preparation. When families own the system and know how to care for it, a short visit can prevent months of poor performance.

What Australian support can achieve

Australia's Nepali communities in Sydney and Melbourne offer a direct connection to the work. Families can discuss the realities of cooking dhal bhat, heating tea and living with smoke with local diaspora groups, while retailers and builders can contribute practical advice. These relationships can turn an abstract housing concern into informed support based on how families actually live.

In Australia, donors often give through registered charities, workplace programmes and one-off or monthly gifts. When an organisation is eligible, donors may claim a tax deduction on eligible donations, so keeping receipts matters. Supporters should still check a charity's registration, governance and financial reporting rather than assuming every appeal has the same accountability.

Funding can cover more than metal stove parts. It can pay local craftspeople for training, transport for components, fuel trials and follow-up home visits. Housing and health services can also use the installation visit to identify families needing safer shelter, a clinic or other assistance. The strongest results come from combining a sound stove with secure housing, clean water and accessible care, rather than treating equipment as a stand-alone fix.

Put knowledge behind a safe kitchen

Listening to lived experience belongs alongside technical planning. The personal account of writing to my father offers a moving example of how reflection can help people make sense of family experience. The same principle applies in Nepal: installation teams should hear the priorities of cooks and caregivers, explain each maintenance step and leave them with a system they trust.

Practical support can begin with a donation to One Home Foundation, a workplace giving contribution or a shared meal that brings the issue into community life. People with building, ventilation, health or project-management experience can volunteer to help train local technicians. Organisations can also arrange a demonstration stove and invite a Nepali cook to explain how a better design changes an ordinary morning.

Choose a specific way to contribute and follow it through, whether that is a monthly gift, a workplace appeal or an introduction to a capable local partner. Each contribution can fund safer cooking, skilled local work and follow-up that keeps a stove working. With thoughtful installation and community ownership, a family can spend less time breathing cooking fumes and more time building a healthier future.
