Which Is Best - Convector Heater Or Oil Filled Radiator

Oil-filled radiators are better than convectors because they last longer, provide better heat transfer, and are less expensive.

The heating option of the convector and oil-filled radiator are the same only difference between them is their installation method.

Convectors are installed on top of the ceiling while oil-filled radiators are placed under the flooring.

However, convectors are easier to install and require less maintenance.

There are many cheaper convector heaters you can buy in the market but they will not give good results as compared to a quality one which has been manufactured by experts.

So before buying any cheap product make sure that it meets all your requirements like durability, efficiency, etc.

If you want to know more about these two options then read this article 'till the end.

Convector heater vs oil-filled radiator

Which is most efficient?

Convection heaters and oil-filled heaters have been used for decades now. Both types work well when properly maintained.

The main differences between the two are:

  • Convectors use forced air circulation whereas oil-filled heaters rely on natural gas. This means that convectors must be vented outside, while oil-filled heaters do not need venting. It has a convection current that circulates through the coils inside the unit. It heats up the surrounding area with hot air.
  • On the other hand, an oil-filled system uses radiant energy from the flame to warm objects directly.
  • Oil-filled systems also tend to produce fewer emissions than convectors.

How much does each cost?

A typical convector costs around 100-200 UK pounds; however, if you're looking at high-end models, expect to pay upwards of 500 UK pounds.

Oil-filled heaters are cheaper to operate since there's no fan required. They also don't produce much noise.

Some budget models of these heaters have supplementary warmth that can help keep rooms warmer during the winter months.

The source of heating should always be chosen based on what type of room you’re trying to heat. For example, a living space requires a different kind of heating than a bedroom.

If you live in a cold climate, consider installing a combination boiler/convector heater. These units combine both technologies into one compact package.

Convector pros and cons


  • It's cheaper than heating your house with oil
  • It's environmentally friendly
  • It can heat up to a higher temperature than an electric heater
  • You don't have to worry about it breaking down, like an electric heater.


  • Heating up takes longer than an electric heater

Oil-filled radiator pros and cons


  • Radiator stays cool when engine overheats
  • Radiator stays cold when engine isn't running
  • Radiator holds up to heat longer than air-cooled radiator


  • Radiator can leak oil if it breaks
  • Radiator doesn't work as well with water-cooling systems
  • Radiator leaks oil into engine bay
  • Can lead to less moisture.

What size should I get?

If space isn't an issue, go ahead and choose whatever model suits your needs. But if you plan to place multiple units throughout your home, consider getting larger ones so you won't have to move them often.

You'll find that convectors come in sizes ranging from 1 cubic foot to 10 cubic feet.

Should I buy an electric radiator or a convector heater?

Now a day, many people have difficulty choosing the right types of heaters they can use in their homes.

  • Electric Radiators

An electric radiator works just fine for smaller spaces such as bedrooms and bathrooms. Electric radiators are easy to maintain and clean.

You simply turn off the power switch and remove the cover plate to access the elements.

However, electric radiators aren't very effective in large areas where temperature control becomes important. In addition, they take time to heat up and cool down.

This type of heater can also be used in small spaces.

The average efficiency of electric radiators has a high-efficiency rating which means less electricity consumption. However, these radiators do not provide any additional comfort features.

  • Convectors

Convectors offer better performance than electric radiators. Convectors provide an even distribution of heat across the entire room.

They also require less maintenance compared to electric radiators. However, convectors may become noisy depending upon their design.

In order to avoid any problems, make sure to purchase quality products. Also, ensure that all parts are working correctly before using them.

Do oil filled heaters use less electricity?

Oil-filled heaters only used minimal effective heating solutions thanks to their low cost. These heater appliances nowadays have higher energy efficiency ratings.

It has a central heating unit that uses natural gas or propane fuel. It heats up quickly and efficiently. The main advantage of this kind of heater is that it does not emit harmful gases.

The distribution of warmth and comfort over time can vary greatly between different models. Some heaters will distribute warmth evenly while others might leave some rooms colder than others.

These heaters are ideal for those who want to save money but still need good heating solutions.

Are convector heaters bad for your health?

Convector heaters may help save energy costs, but they can cause harmful side effects, such as dry skin.

According to the UK Department of Energy, convectors use about 25 percent of the electricity used in homes. If you live in a hot area, you might want to consider using a fan instead of a convector heater.

Electric radiators are using electric heating with no combustion process involved.

This makes them safe for indoor air quality. They don’t produce carbon dioxide emissions either.

Last words

Both convector and oil-filled heaters offer great value for money. But, if you plan to invest in a long-term solution, go for connectors.
