Electric heaters of any type are unsafe to leave running overnight because they carry a significant amount of risk.

If you have a 24 kW boiler, it will require 24 kWh of energy for each hour it's working to heat your home. If it's running for 2 hours then it will be 48 kWh and so on. The cost of your energy: On average gas in November 2024, is currently 6.4p per kW/hr. Electricity is 24.5p per kW/hr.
It isn't bad to run your heating system on a 24/7 basis if outdoor weather conditions demand indoor warmth. For many households, maintaining a constant indoor temperature is the only way to survive the winter. Just be aware that this is likely to cause additional wear and tear on your heating system.
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
