Guide to Buying a Heater

Even well-insulated homes with central heating may need a boost in chilly rooms. Whether it’s a long unused spare room, a conservatory, or just because the temperatures have dropped, there are a few different space heaters out there, all with their own pros and cons.

Fan Heaters

The concept of a fan heater is based on how people used to keep cool in the days before air conditioners: blow air over a block of ice. But as we want heat, this fan blows air over a hot element thus warming the room. Wood burner-effect fan heaters look great, and some are wall-mounted with a “flame” feature that works independently of heat to give a cosy feel to any evening. Fan heaters require good ventilation around them as they need to suck air in. They can be noisy but they do produce immediate heat. Although, the disadvantage of that, is the room begins to cool as soon as it’s switched off. Traditional fan heaters are often found mounted on bathroom walls. Most now have thermostats, which is beneficial as they will cut off when the desired temperature is hit. Some people, especially contact lens wearers, have commented that they can dry the air out.


  • Compact and highly portable
  • Can easily be wall mounted
  • Produces direction heat quickly


  • Decreases humidity
  • Heat is highly directional
  • Produces noise as well as heat

Convection Heaters

Convection heaters build up warmth inside them until the heat is forced out via natural ventilation (called convection). As they have no fan, convection heaters are bigger and quieter than fan heaters. The metal exterior can become very hot to touch but because of their size, they have fewer safety concerns as the element is deep within the frame.


  • Will not cause drafts
  • Raise ambient temperature rather than in one direction
  • Virtually silent during operation as they have no moving parts


  • Poor directional heat
  • Casing will become hot during operation
  • Tend to be bulkier than other heater types

Oil-Filled Radiators

Oil-filled radiators run on convection but because the oil inside is heated, they hold their heat. So if you want a room kept warm for longer periods of time, oil-filled radiators are your best bet. They don’t have the immediate or directional heat of a fan heater, but once hot, keep the room warm with far less electrical usage. Once the room has reached your optimal temperature, set the thermostat and the heat simply kicks in every now and then to maintain it. It might take longer to heat, but it’s more efficient in the long run.


  • Highly cost efficient
  • Controllable via thermostat
  • Maintains ambient heat


  • Tend to be heavier than other heater types
  • Build up heat slowly over time
  • Doesn't produce directional heat

Halogen Heaters

A halogen heater uses halogen-filled tubes to produce heat and a bright light. As light is produced, this means that the electricity taken is not 100% converted to heat. That said, they do cost the lowest to run (along with oil-filled radiators). Some people find the light too bright and the heat too focused, but then again, this makes them good for small, dark rooms. Halogen heaters often have an oscillating function, variable heat outputs and feature an auto cut-out if knocked over.


  • Lightweight and portable
  • Oscillating directional heat
  • Heats up immediately


  • Produces light as well as heat
  • Does not produce residual heat
  • Won't heat larger rooms alone

Portable Heaters

Portable space heaters often come with the strict instruction only to plug directly into a wall socket – not an extension lead – so check where you want the heater and the closest wall socket.

The wattage of the heater you want will depend on the size of the room you want to heat, but most now have thermostats to regulate the heat output. Space heaters will up your electricity bill, so be aware that costs will rise with the temperature. If your heater doesn’t have a timer, you will need to remember to turn it off.
