1 Type: Electric vs. Gas
Your first consideration is likely to be whether to opt for an electric or gas heater, with both types having their own unique benefits.
- Better for enclosed areas
- Cheaper purchase price
- More energy efficient
- Less noisy
- Usually cheaper to run
- Do not require an electrical outlet
- Works during power outages
- More portable
2 Heating: Heating Elements
There are three main types of heating element available for electric heaters: quartz, column heaters and ceramic.
These heaters have one or more glowing tubes that act as the heating element and are often the cheapest models.
The heating elements are usually hidden behind a metal grid, but are still exposed, so you may need to be careful if you have children or small pets.
Column heaters are also known as oil heaters, as while they are powered from an electrical socket, they use oil as a heat reservoir (rather than a fuel).
While safer than quartz heaters, they can take a while to get started.
Using a ceramic heating element, these appliances generate heat from a wider area than quartz models.
They can also be quite thin, enabling you to mount them on walls.
3 Features: Additional Features

- Fan for better distribution of air
- Overheat shut-off mechanism
- Oxygen depletion safety device (gas heaters)
- Flame failure shut-off (gas heaters)
- Oscillation – turns from side to side for better heat distribution

4 Controls: Control Settings
More expensive models will tend to have electronic controls and displays, with a range of automated programs.
For instance, some heaters are controlled thermostatically, which means they measure the room temperature and switch the unit off and on when necessary.
There are also programmable timers that allow you to choose what times of the day you would like the heater to function.
