Half truth. Only one was killed. What actually happened was not a
faulty tank, but a faulty immersion heater in an entirely standard

into the roof tank which then eventually distorted/broke over the
people in the bedroom below.

Which if you read carefully shows the tank wasn't properly supported -
probably just resting on joists, and the thermostat wasn't BS marked.
They'd also heard the water boiling before but done nothing about it -
which seems madness given they'd got children.

Almost as mad as not servicing a boiler for 12 years.
