An Overview Of 11 Fin And 13 Fin Oil Heaters

Oil heaters are also known as radiators because they radiate the heat from warm oil inside the metal body. The heaters have several columns by which the oil passes. They are also known as fins. These fins make a significant difference among different models of oil heaters. 

That’s because the number and size of the fins decide the heat capacity of an oil heater. Therefore, comparing 11-fin vs. 13-fin oil heaters is probably the best way to check out the differences between these famous models. 

Difference Between 11-Fin and 13-Fin Oil Heater

If you look at the key points that make the difference between an 11-fin and 13-fin oil heater, you can decide which one to get for your bedroom and which one is for your drawing room. Here’s what you need to look at!


There’s not much difference in their dimensions. The 11-fin oil heater has a dimension of 65 × 53 × 15 cm, and the 13-fin oil heater has a size of 65 × 59 × 16 cm. 

However, the 13-fin oil heater will be larger than the 11-fin when you look at them with the naked eye. There will be some problem in space in your bedroom if you want to set a 13-fin oil heater. 

On the other hand, the 11-fin heater will be perfect for small spaces like a bedroom or reading room. 

Fin Size & Number

The fins of the 11-fin oil heater are 14 × 58 cm in dimensions. To clarify the confusion, the number “11-fin” indicates that this model has 11 fins attached, and all contain oil to radiate the heat. 

Therefore, the model 13-fin oil heater will have 13 fins attached to it, and each of the fins has dimensions of 12.6 × 57 cm. 

Though the size of the 13-fin oil heater is a bit small compared to the 11-fin oil heater, the 13-fin will have the upper hand in heat dissipation. 

Heating Capacity

It’s the most crucial part to look at if you are thinking of an 11-fin vs. 13-fin oil heater. The heat capacity is totally dependent on the number of fins and their dimensions. 

That’s because the oil is placed inside the fins. The oil absorbs the heat and radiates through these metallic fins. Therefore, the 13-fin oil heater can deliver much heat in less time than an 11-fin oil heater. 

If you need your living space to warm up quickly or have a continuous source of high heat in winter, the 13-fin model is a perfect choice. 

On the flip side, the 11-fin model is also a good choice. But it’s not much quicker or efficient in delivering heat throughout the room. 

Usage Area

As mentioned earlier, the 13-fin oil heater can deliver much more heat than the other. So, clearly, that’s not the proper choice for your bedroom. This much heat in the bedroom will be unnecessary and may feel irritating instead of comfortable. 

An 11-fin oil heater is perfect for small bedroom usage, and the 13-fin heaters are suitable in the drawing-room or other large areas. 

Similarities Of A 11-Fin and A 13-Fin Oil Heater

The comparison of 11-fin vs. 13-fin oil heaters should also include similarities along with the dissimilarities that may help to make a decision to buy. You should also know what features both heaters have to offer in common. 

Overheating Protection

If you use a space heater, the most common complaint will be overheating, which could be dangerous sometimes. Well, that’s not the case in terms of oil heaters. 

Both 11-fin and 13-fin models will provide overheating protection. The heat from electricity can’t reach the boiling point of the oil. And the internal pressure is also controlled so that there is no risk of overheating. 

There’s also less possibility of cracks or leaks because of their thick metal body. 

Adjustable Thermostat

An adjustable thermostat is a unique feature of an oil heater. It helps you to control the temperature according to your wish. Some thermostat even comes with programmable settings, which means you can set the time and amount of heat you need. 

Do you want to feel cozy after returning home? Just set the heater to start 15 to 20 minutes early before you come home. Don’t want too much heat while sleeping? Just select the temperature at a lower level and fall asleep! 

Frequently Asked Questions

How does an oil heater function?

Basically, an oil heater uses radiant oils as a medium to radiate the heat that comes from electricity. The oil gets heated through electricity but remains under its boiling point. And then, the heat scatters to the surroundings through the heater’s metal body. 

How many years can I use my oil heater?

An oil heater can serve up to 20 years if you take good care of it. The average lifetime of an oil heater is about 14 to 16 years. The overall life expectancy of an oil heater is related to the internal temperature of the oils. 

Is there any chance of catching fire by an oil heater?

Typically, there’s no chance of creating fire through an oil heater. To put it simply, oil heaters are fire-proof until there’s a leak or crack and the radiant oil comes out. If the oil encounters induction coils or any ignition sources, only then will the fire break out. 

Does an oil heater save energy?

The energy-saving capacity of an oil heater depends on your type of comparison. If you compare an oil heater with other space heaters, it consumes less electric energy. But if the comparison is with your belongings like computers and vacuum cleaners, it exceeds them all in power consumption. 

Can quartz heaters replace oil heaters?

We don’t think so. A quartz heater is highly efficient in warming people within its range. However, it’s not good at warming the room. But an oil heater can do both with just a little extra power consumption. 

Bottom Line

Oil heaters are made to bring comfort to your life in winter. But too many variations make it difficult for you to choose an oil heater for your bed or hall room. 

The 11-fin and 13-fin models of oil heaters have colossal popularity among customers. If you are going to buy one of them, don’t forget to take a glance at the comparison of an 11-fin vs. 13-fin oil heater and then go shopping. Hopefully, you will have enough clarity and information to decide by yourself!
