We are now living longer, hyperthermia is a big killer when temperatures drop well below freezing, should we be prepared for the instance when our gas boiler fails and we are unable to find a heating engineer to carry out repairs at short notice.
This argument also seems fallacious to me. Deaths from hyperthermia amongst the elderly are overwhelmingly due to 'fuel poverty'. The unfortunate people who die from this, a couple hundred a year IIRC, do so because they can't afford to run their heating. It seems unlikely that they would be in a position to buy and maintain two boilers 'just in case'.
