So after designing, inspecting and tearing down however many electrical & electronic appliances, I should change my views on how engineers & businesses work simply on the basis of one sample that does not contradict what I said.
I dont use, design or sell oil rads. I do however have misgivings about the lack of earthing of certain heaters on the market, and the percentage of portable heaters that have safety issues I would probably not welcome in my own home.
FYI domestic appliances are required to remain safe after one fault. For a serious problem to occur, the following would need to happen:
- thermostat failure
- coats etc covering much of the heater's area
- Backup thermal cutout failure
So if you cover the things with clothes, they might have a point. If not there isnt an issue.
