What to Consider When Shopping for the Best Electric Radiant Heater

Below are the factors to consider when shopping for oil-filled radiant heaters.

Electric Radiator’s Price

The cost of the radiator you want to buy is always a factor. Your budget will limit what kind of product you can get.

Radiators, like the many types of small space heaters, vary in terms of features, brand, style, and quality. Naturally, these things affect their purchasing, operational, and maintenance costs. So, it’s essential to consider not just what you will spend on buying a radiator but also what you will spend on electricity and long-term repairs and replacement.

For starters, a standard electric radiator heater will cost anywhere from $200 to $1,500, though some may cost much less. So that’s a wide range of costs to suit many budgets. But it would help if you also considered whether the labor costs are included in that price. The more work you need to do to install a radiator, the more initial costs it will have. In addition, you also need to consider the delivery fees.

Another critical aspect of the cost you should think about is how much you will pay for both thermal oil. Mineral oil, such as diathermic oil, is popularly used in oil-filled radiators because they are excellent heat carriers.

But how much you use will depend on the kind of radiator you choose. Also, you should consider the electrical requirements of your radiator. The wattage and electricity tariffs will largely determine costs in this regard. But a standard 1500W heater will cost about $25 a month if you run it on for eight hours daily.

Space You’re Heating

The amount of space you need to heat also affects your choice of radiator heater. You require a bigger and possibly more expensive heater to warm larger spaces than any small room. So, if you need to heat both small and large rooms, it may be best to consider the needs of the bigger spaces. Of course, you can always leave the radiator on for a shorter time in the smaller rooms.

When calculating how much heat you need for each space in your home or office, you will measure it in British Thermal Units or BTU per hour. It is based on how much energy is required to heat one pound of water and raise its temperature by one degree Fahrenheit.

One way to determine your BTU needs is by measuring the area of your space in square feet and calculating the volume by multiplying the area by height. If your room is odd-shaped, you need to divide it into measurable sections and tally the measurements of each of them to determine the total size you need to heat.

Various climatic conditions, room positions, and use of spaces will also determine how many BTUs your radiator will need. For example, you should multiply the cubic feet by five to obtain the estimated BTU for a living room. The same rule applies to a dining room. However, your bedroom volume should be multiplied by four while other common areas, like the kitchen, should be multiplied by three.

On the other hand, you need to add 20 percent to your BTU estimate if you have French windows and 15 percent for rooms facing North, but subtract at least 10 percent if you have installed double-glazed windows.

Of course, if you are in a hot climate zone, you will require less heat than those living in icy areas. Therefore, it would be best to use an online calculator to determine how many BTUs you would need for your location, then research the radiator that can deliver that amount of heat.

Oil-Filled Heater Wattage

You may also want to factor in your oil-based heater’s wattage because it affects your energy bills.

Generally, dividing your estimated number of BTUs by 3.41 will give you an idea of the radiator’s wattage, allowing you to select the right one for your needs. For example, if the space you need to heat requires 3,410 BTUs, you must purchase a 1,000-watt radiator.

Style of Radiator Heater

Concerning oil-based electric radiators, several styles exist. First, you can opt for wall-mounted radiators, which you can install on the wall. These heaters are excellent for narrow or small spaces because they take advantage of the existing vertical space.

Alternatively, you can opt for freestanding radiators. These can stand independently in any room in which they are installed. And they are excellent options if you are looking for portable heaters you can move from one room to another.

In addition, you should consider the heating method. Some heat the room in the form of radiant or convection heat, while others use forced air. Each way offers its pros and cons. So, it helps to understand the benefits your radiator offers.

Radiator Fans and Noise Levels

Electric radiators are generally more efficient than other types of radiators, such as ceramic heaters, that use different power sources. And they often use radiant heat, which involves heat emission by heated surfaces. However, many also require fans, whose efficiency levels are measured as cubic feet per minute (CFM).

The general rule of thumb is that a higher CFM rating means a fan can move larger volumes of air. This is because the more efficient a fan is, the higher the volume of air it can move per minute. But that also means they might be noisier.

A drawback to larger fans is that they tend to be noisy fans.

So, it would help if you also judged radiators based on their noise levels. The more silent they are, the better off you will be. Then, you can have peace when using them.

Ease of Use

A radiator’s ease of use begins right from its installation. If you need to use it only in one area, it should be placed where it is out of the way, enabling you to heat the room efficiently. However, if you need to use it for multiple spaces, it should be portable so you can cart it around.

It also helps to consider the safety features since oil-filled heaters can be a fire hazard when misused. For that reason, you need to look for radiator guards to keep flammable materials farther away from the heat, high-quality thermal fuses to trigger an automatic- shutoff in case of a problem, and tilt sensors to cut off power when the radiator is destabilized.

In addition, you can consider any bells and whistles that make a radiator easy to use. For example, a programmable thermostat with different temperature settings enables you to pre-set your desired temperatures, depending on the energy you need at any given time. In addition, some adjustable thermostats are so intelligent and precise that when the room temperature rises above a specific level, they will shut down the radiator and save you energy and money.

Also, you can shop for radiator heaters that allow for remote control via Wi-Fi or a mobile app. It will enable you to set that digital thermostat even when you are not home.

Are Electric Radiator Heaters Safe?

Standard electric heaters are pretty safe. However, their safety standards vary depending on the materials’ quality, built-in safety features, usage, and testing done by institutions, such as the U.S. Consumer Product Safety Commission. So, you may want to pay attention to recalled products as your research’s first step.

Electric Radiator Heater FAQs

Below are answers to some of the electric radiator heater FAQs.

Do Electric Radiator Heaters Use a lot of Electricity?

Electric radiators convert 100 percent of electrical energy into heat, making them very energy-efficient. However, whether they use a lot of electricity depends on how well insulated your home is and how much heating you like to do.

The more energy-efficient your home office or any other room is, the less electricity you will use. Also, if you live in a cold climate, expect to spend more on your electrical bills.

It is also worth noting that oil-filled heaters are energy-saving. That’s because the electricity heats the oil, which takes a long time to cool.

Are Electric Radiators a Good Idea?

Electrical radiators are an excellent idea if you are connected to the electric grid. And oil-filled ones can maintain heat for longer. Therefore, you should use these kinds of radiators for heating regular-used spaces for prolonged periods.

Are Radiant Heaters Safe to Use Around Children and Pets?

Remember that young children and pets tend to explore and get in trouble. So, no matter how safe an electric radiator is rated, you have to be extra careful to ensure kids don’t make it unsafe to use. In addition, the radiators can be hot to the touch causing burns.

Can an Electric Radiator Heat a Room?

Electric radiators can heat an entire room. But how well they do that depends on their wattage and the amount of heat they can produce.

Are Electric Radiators Cheap to Run?

Electric radiators can be cheap to run if they are made of high-quality materials and use innovative technology to set the thermostat, so the radiator only switches itself on when it needs to and off when heating is no longer required.

Can You Leave An Oil-Filled Radiator On Overnight?

You can leave an oil-filled radiator on overnight in some circumstances as long as it lacks an exposed heating element and is designed not to get too hot.

However, there is always a small risk of fire. But you can lower that risk if you ensure your children and pets don’t have access to the heater. Also, it would be best if the radiator has in-built safety features, such as timers and anti-tilt sensors, that shut it off when it tilts or experiences any other issues.
