Our favorite product on the list has an efficient heating system. It’s configured to offer three heating options — including 900 and 1500 watt modes — and five temperature settings — 65, 70, 75, 80, and 85 degrees Fahrenheit options — to enable the user to select customized heating preferences. This can be done by employing the intuitive LCD screen and the adjustable thermostat

This oil-filled heater was designed for portability. A four-swivel wheel setup enables 360-degree rotation. This ensures you can move your heater from one room to another without breaking a sweat. 

A remote control is included to provide a safe method to control the heating. Other safety features include the power indicator light that informs you when the light is on and an integrated overheat protection feature that prevents damage from occurring to the heater from overheating. In addition, a tip-over safety mechanism switches off the heater if mistakenly knocked over. 

Oils, in place of fans, are used to heat the room; this enables whisper-quiet operation. No one wants an annoyingly loud device, as they aren’t conducive to sleep or work. Both warmth and quietness are offered by the heater, which allows you to focus in a comfortable environment.

In addition to this, the heating element is permanently sealed inside the heater, eliminating the risk of inflammation. A patented anti-freeze mode is included to aid in the prevention of frozen pipes. 

But more importantly, for parents, there’s a children’s lock function that prevents children from changing the heat setting and potentially harming themselves.

The design of this heater is visually captivating. It doesn’t look like the usual oil filled radiators produced by generic brands. The absence of the usual thermal slots is immediately noticeable. In place of them, the oil heater is designed to have a complete form that resembles a rectangular prism. 

These unique thermal slots aren’t only for aesthetics, but function too. They have been designed to maximize heat flow while having a regulated low surface temperature.

The design of this product includes an integrated EnergySmart technology that makes it energy-efficient, saving you money on your electricity bills. The entire room is made warm by this compact and powerful oil heater, without spending big bucks on power.

Digital EasySet Controls are featured. These enable a one to 12-hour timer, which, when paired with the thermostat, delivers three heating modes.

For example, you may want the oil heater to be at its warmest during the night and early morning hours while being slightly cooler at midday. 

Safety and mobility have been a priority in the design of this product. An ergonomically designed handle and near-frictionless wheels ensure this heater is portable. The safety features include a tip-over mechanism and thermally insulated wiring. 

Unlike the previously reviewed product, the Honeywell HZ-789 is accompanied by a three-year limited warranty. Products that are involved with heating are usually very hard to offer a guarantee.

Buying Guide: How to Choose the Best Oil Filled Space Heater

Heating Capacity With Regards to Room Size 

When looking at the best oil filled radiators to buy, you must consider the room you wish to use it in. If the room is large, then you must opt for a larger oil heater. These usually have a much higher output than smaller ones but are also more likely to be expensive. A heater that can function well on a 1500-watt output is, in most cases, sufficient for a medium to large-sized room. 

But if this isn’t the case, you must accept the fact you may have to buy multiple heaters and position them at different ends of a room. 

Energy Efficiency

Paying attention to the amount of electricity your electric heater will use is essential in determining whether it’s a great fit for you. Naturally, since we now live in a climate-change conscious world, using more energy than is necessary should be avoided at all costs. Even if that may include buying a more expensive product — the money you save after purchase will justify the price.

Oil filled heaters are more efficient than exposed-element heaters since the heat energy generated is transferred into the oil instead of being lost throughout the room. Find a good balance between the power you’re comfortable using and the heat you require for your room.

Power and Wattage 

The general range of oil filled heaters is between 700 to 1500 watts. More watts translates to more heat produced. But this doesn’t mean you will feel warmer than you would with an oil heater with less power. The definitive factor here is efficiency. 

Even though more power is produced, some oil heaters are inefficient, and all that energy is lost to other things, like sound energy, for example, if your heater is noisy. For better comfort, your heater must have sufficient power and good efficiency. 

The only way to discover the efficiency of a product is to trust the manufacturer’s claims. This is why you should only buy from reputable brands. 

Noise Level

Oil-filled space heaters produce considerably less noise than other types of heaters. But sound can be produced from the clicking of either the thermostat or the electrical element. This can be annoying and prevent people from sleeping. 

To avoid this, manufacturers have included sound insulation. This means the heater is essentially silent when operating. 

Timer Settings

Being able to turn your oil filled heater on or off automatically at certain times of the day is now standard in high-end products. This feature is very handy and is usually carried out by remote control. This also aids in reducing your electricity consumption because the timer designates periods during the day when your heater will be off. 

FAQ

What Price Range Is a Good Air Oil Heater?

In our opinion, a good oil filled radiators usually start from 100 dollars and upwards.

Should I Buy a Second-Hand Oil Heater?

No. Avoid this. It’s difficult to determine energy-efficiency when a product isn’t brand new.

Which Rooms Should I Have My Oil Filled Heater in If I Only Have One? 

Get a portable heater that you can move around depending on which room you’re using. Rooms that are closer to the kitchen are usually warmer than others because of the heat produced by the stove. 

Conclusion

The detailed guide has hopefully convinced you of why oil heaters are a compelling alternative to standard heating systems. The PELONIS Oil Filled Heater is the best oil filled heater that also offers value for money. 

But that doesn’t mean it’s the best product for everyone. Other people may prefer cheaper options, such as the COSTWAY Oil Filled Radiator Heater, or products that offer something different, like being more stylish, such as the DeLonghi TRD40615E.

Whatever you decide to buy, ensure you help protect the planet by having an energy-efficient oil heater.
