Heating a Damp Flat with a Toddler and an Asthmatic Grandmother
The Borg family live in a one-bedroom ground-floor flat in Msida with their daughter, 2, and Mrs Borg's mother, 78, who has asthma. The flat has no central heating, single-glazed windows and a north-facing bedroom with black mould on the wall behind the wardrobe. They use a portable butane gas heater in the living room in the evening and dry clothes on a rack indoors. The child's room drops to 14 °C at night. The electricity bill is €95 a month and they can afford €30 more in winter. The landlord will not install a new heating system but will allow wall fixings. Mrs Borg is worried about the gas heater because her mother once felt dizzy after using it. The flat has a working carbon monoxide alarm in the hallway only.
1. Evaluate the risks in this household and recommend changes to how the family heats and ventilates the flat.

Three hazards interact: the unflued gas heater, the damp, and the vulnerability of the occupants.
- The butane heater consumes oxygen and produces water vapour and carbon monoxide. The grandmother's dizziness is a red flag. A CO alarm in the hallway does not protect a bedroom. The heater should never be used in a room where anyone sleeps, and never overnight. It needs a permanent vent and regular servicing.
- Indoor drying at 14 °C adds several litres of water to the air per wash. That water condenses on the cold north wall and feeds the mould.
- The occupants: a toddler cannot regulate body temperature well, and the grandmother's asthma is worsened by mould spores and cold air.
Recommendations: move the gas heater out of the bedroom and use it only in the living room with a window slightly open, never while sleeping. Pull the wardrobe away from the mouldy wall, clean the mould with a fungicide and keep the wall ventilated. Dry clothes in the bathroom with the extractor fan or window open, or use a launderette for large items. Use an electric oil-filled radiator with a thermostat at 18–20 °C in the grandmother's room overnight; it is safer and adds no moisture. Add a second CO alarm near the bedroom.
2. Plan how to spend the extra €30 a month over the three coldest months. Justify each choice.

€30 a month for three months is €90. The principle is to heat one room well and keep the rest dry and ventilated, rather than heat every room poorly.
- €35: a second carbon monoxide alarm for outside the bedroom, plus a room thermometer. This addresses the most serious risk first; the existing alarm does not cover the sleeping area.
- €25: draught-proofing - self-adhesive foam strip for the single-glazed windows and a brush for the bottom of the door. The landlord permits fixings. This reduces heat loss before more energy is bought.
- €30: a thermostatic plug-in radiator for the grandmother's room, set to 18 °C at night. Keeping her room at 18 °C protects her asthma and reduces the risk of falls and chest infections; the living room can be kept at 20 °C during the evening only.
- €0: behaviour changes - close curtains at dusk, open them in the morning, keep the bedroom door open for air circulation, and do not open the window wide.
If the electricity bill rises above €125, the family should write to the landlord about the mould, because damp from a structural defect is a housing fitness issue, not a heating choice.
3. Discuss the mould and the grandmother's asthma. Who should act, and what should they do?

The mould is not merely a cleaning problem. Black mould behind a wardrobe on a north-facing wall indicates condensation from poor ventilation and cold surfaces, possibly also a leaking gutter or rising damp. For a 78-year-old with asthma, spores are a health issue, not an aesthetic one.
What the family can do: clean the mould with a fungicide while wearing a mask, move the wardrobe away from the wall, ventilate daily, stop drying clothes indoors, and move the grandmother's bed to an internal wall so she does not sleep against the affected surface. A dehumidifier would help but costs about €0.15 an hour to run, which competes with the heating budget - fixing the source is better.
What the landlord must do: structural repair is the landlord's legal responsibility. The family should write a dated letter describing the mould, the toddler's and grandmother's symptoms, and the steps already taken, and request an inspection. They should keep photographs and a copy of the letter. If the landlord refuses, the local housing authority can advise.
The judgement is to separate what the family controls (ventilation, cleaning, furniture placement) from what requires the landlord (repair), and to act on both rather than treating the mould as a cleaning failure.
