A coroner has warned of the dangers of gas heaters at an inquest into a student's death from carbon monoxide poisoning at a holiday cottage in Angus.
Tom Hill, 18, from Hampshire, died while staying at Glenmark Cottage near Tarfside with the family of his girlfriend Charlotte Beard in October 2015.
A previous investigation found that cracks in a bathroom heater led to it producing carbon monoxide at dangerous levels.
Coroner Jason Pegg recorded a conclusion of accidental death and said he would prepare a preventing future deaths report about the lack of warnings on liquid petroleum gas (LPG) heaters.
He said a Health and Safety Executive (HSE) investigation found the LPG cabinet heater should not have been used in a room as small as the bathroom, which had no ventilation because the windows had been painted shut.
Mr Pegg added that damage to the heater was also a "crucial factor".
He said: "The primary feature from the HSE is the heater should not be used in such a confined place."
Mr Hill collapsed and died 11 days after the holiday home operator was told about a previous tenant becoming unwell.
The inquest, which was held in Winchester, heard that a fatal accident inquiry (FAI) was also held in Scotland in 2023 into Mr Hill's death.
The FAI said external reasonable precautions could have been taken by the firm that could have avoided Mr Hill's death.
Cottage owners Burghill Farms and Piers Le Cheminant, who sub-let the property to holidaymakers, were prosecuted for health and safety breaches in 2021, with the farm being fined £120,000 and Le Cheminant being fined £2,000.
Mr Pegg added: "My concern is that in rental cottages and some tented properties, there are going to be heaters of this nature in rooms that are too small which does raise a concern for future deaths."
