I'm always concerned about the safety of using space heaters for large rooms. Luckily, I had peace of mind with Dr. Heater. It features both tip-over and overheat protection.

Useful Note:

Tip-over protection automatically shuts the heater off if by accident it ever knocks or tips over. This is a very important function if you have pets or children. 

It also boasts features like a remote control, an electronic thermostat with a range of 50 to 85 degrees, and caster wheels for easy movement.

I could quickly move it from room to room and control the heating element from afar.

The unit is equipped with a 12-hour automatic shut-off timer and comes with a lifetime filter.

Compared to other top space heaters on this list, the Dr. Infrared Heater stands out for its dual heating system and ultra-quiet operation, making it more efficient and quieter than options like the Lasko Oscillating Heater.

Who is the Dr. Duraflame DFI-5010-01 best for?

The Duraflame DFI-5010-01 is perfect for homeowners who want to maintain a cozy atmosphere with the charm of a traditional fireplace without the hassle of actual firewood.

Pros
  • Safe around kids and pets
  • Realistic flame effect
  • No fumes
  • Portable design
CONS
  • Requires nearby outlet
  • Door must be open for the remote control to work

If you're looking for a stylish electric space heater for your home with vaulted ceilings, the Duraflame DFI-5010-01 is a great choice.

I absolutely loved the included remote control. It's a game-changer for me, allowing me to tweak the temperature and flame brightness from the cozy confines of my sofa.

I appreciate the clever design touch where the digital thermostat and knobs are discreetly tucked away behind the fireplace door, maintaining the illusion of a traditional fireplace.

From a distance, my friends really thought I had an old wood-burning fireplace!

Finally, this heater has a traditional look with a durable metal body, side viewing windows, and an operable beveled glass door, which adds to its authentic fireplace feel.

Who is the DeLonghi TRD40615E best for?

The DeLonghi TRD40615E is best suited for allergy sufferers who need a dust-free heating solution.

Pros
  • Energy-efficient heating
  • Digital control panel
  • Quick heat-up time
  • Safety features included
CONS

I've always been curious about oil-filled space heaters, and the De'Longhi Dragon Premium model didn't disappoint. It's a class apart in the oil-filled heater category.

The manufacturer claims its design allows for 75% more radiant surface area, ensuring more heat is transferred throughout the room.

I found it heats up quickly and distributes warm air efficiently due to its convection heating effect and unique battery design.

This is one of the best space heaters for large rooms without a fan, which means it distributes heat directly and doesn't circulate dust or allergens, which was a big concern for me as I'm allergic to dust.

Navigating the settings was a snap with the user-friendly digital control panel and its clear LED display.

DeLonghi TRD40615E LED Display

I found it very easy to use, and it has functions like a 24-hour timer and an ECO Plus feature for energy optimization.

This oil-filled radiator heater includes an ECO Plus heating mode for energy optimization and a wide temperature range to cater to various heating needs.

Who is the Mr. Heater MHVFB30NGT best for?

The Mr. Heater MHVFB30NGT is best for individuals who need to heat large spaces like workshops, garages, or barns where an electric heater might not be as effective.

Ho To Buy The Right Heater for  High Ceiling Rooms

Which Type of Heaters Are Suitable for Large Rooms?

Several types of heaters work well in large spaces:

  • Infrared heaters:
    These heaters, like the Dr. Infrared Portable Space Heater and the Heat Storm, emit infrared radiation that directly warms objects and people in its path, which means no more cold feet. They are efficient for spot heating and provide immediate warmth, which can be ideal for large spaces with vaulted ceilings.
  • Oil-filled heaters:
    The DeLonghi TRD40615E is an example of an oil-filled radiator, which heats the oil inside its columns, and the heat is then radiated into the room. This type of heater is silent and can maintain hot air for a longer period, making it cost-effective for continuous use.
  • Propane gas heaters:
    The Mr. Heater uses propane gas and is capable of heating large volumes of air quickly. These heaters for large rooms are often used in spaces where electric heating elements might not provide enough warmth or would be too expensive to operate.
space heater types

TL;DR: Different types of heaters have their pros and cons. You should choose depending upon the availability of fuel and the specific function you need.

What is The Coverage Area That Needs Heating?

The floor space a heater can effectively warm is determined by its heat output and design.

For example, the Duraflame and Mr. Heater are designed for large areas up to 1,000 square feet, which is significantly larger than the 300 square feet recommended for the Lasko Oscillating Heater.

It's important to match the heater's capacity to the room size for efficient heating.

TL;DR: Coverage area of the space that needs heating is the first step to choosing your heater.

How High Is the Ceiling?

The volume of the room increases significantly with ceiling height, requiring more powerful heaters.

Heaters with a high BTU rating, such as the 30,000 BTU Mr. Heater, are more effective in rooms with high ceilings.

In contrast, standard electric heaters with a 5,200 BTU output may struggle to provide the same level of warmth in such spaces.

How Much Heat Can Your Heater Deliver?

The heat production, measured in watts and BTUs, is critical in determining how well a heater will perform in a large space.[1]

While most electric heaters on the list provide 1,500 watts/5,200 BTU, suitable for large or medium-size room, the Mr. Heater 30,000 BTU heating output is designed for much larger rooms or colder spaces.

TL;DR: The higher the ceiling the more heating BTUs you need.

What Control and Safety Features Does the Heater Offer?

Control features like adjustable thermostats, eco mode, multiple heat settings, and overheat protection allow for precise temperature management.

For instance, the Duraflame 3D DFI-5010's remote control adds convenience despite its limitation of needing an open door to function.

Safety features, such as the overheating and tip-over protection found on the Dr. Infrared Heater, are essential for preventing accidents.

TL;DR: Overheat protections and tip-over shut-off are crucial safety features to look for.

How Energy Efficient Is It, And What is its Cost of Running?

Energy efficiency affects the long-term cost of running a heater.

The DeLonghi TRD40615E's ECO Plus feature helps to minimize electricity usage, potentially offering lower operating costs compared to less efficient models.

Propane heaters like the Mr. Heater may offer savings depending on local gas prices despite their higher initial heat production.

TL;DR: The higher the energy-efficiency the lower would be your bills. However, higher efficiency models are more expensive to procure.

Other Important Factors to Consider

Are the Walls Well Insulated?

Well-insulated walls retain heat better, allowing the heater to work more efficiently.

This factor is crucial for all heaters but particularly for those with lower BTU output, like the Heat Storm.

What is the Warranty Period in Case Things Go South?

Warranty periods vary. For example, the Dr. Infrared Heater and DeLonghi TRD40615E offer a 3-year warranty, which is longer than the 1-year warranty of the Duraflame 3D DFI-5010 and Mr. Heater MHVFB30NGT.

A longer warranty period gives you more peace of mind, and it also shows the manufacturer has more faith in their space heater.

Does it Have Convenience Features Such as a Remote Control and a Timer?

Features like remote controls and timers enhance usability.

For example, the Lasko Oscillating Heater's remote control and the 12-hour timer on the Dr. Infrared Heater let you control the heater from afar and heat the entire room for a long time.

Does it Produce A Lot of Noise?
Noise level is a consideration for comfort.

The Dr. Infrared Heater operates at a quiet 39 dB, making it one of the quieter options, and resembles white noise, whereas heaters with fans, like the Lasko Oscillating Heater, may produce more noise.

Can You Move It Around Easily?

The heater’s space-saving design is another important consideration. Portability lets you move the heater to where it's needed.

For example, the caster wheels on the Dr. Infrared Heater and the lightweight design of the Lasko Oscillating Heater make them easy to move around.

TL;DR: Understanding the additional features heaters can have allows you to make a more informed decision. Some of these features can be more important to some as compared to others.

How Much Harder Are High Ceilings To Heat As Compared To Standard-Height Rooms?

Heating rooms with high ceilings can be significantly more challenging compared to standard-height rooms due to the increased volume of air.

The basic principle is that heat rises, so in a room with a high ceiling, the warm air tends to accumulate at the top, leaving the lower part of the room cooler.

This means that heaters have to work harder and longer to achieve a comfortable temperature at the level where people actually live and work.

Generally, for every additional foot of ceiling height over the standard 8 feet, you can expect up to a 25% increase in the time it takes to heat a room.

This is because the volume of air can be significantly larger; for example, a room with 12-foot ceilings has 50% more air volume than a room with 8-foot ceilings.

Therefore, it could take notably longer to heat, especially if the heating system is not designed for such spaces.

My advice is to choose a heater with higher BTU ratings to ensure enough hot air output to warm the entire space effectively.


People Also Ask (FAQs)

Where Should I Put a Space Heater For a Large Room with High Ceilings?

Place the space heater in large rooms with high ceilings in a central location to allow for even distribution of heat. For ceramic heaters, direct them towards the living area.

Avoid corners and ensure the heater is away from flammable materials and not obstructing foot traffic for safety and efficiency.

Does it Cost a lot More to Heat a Large Room?

Yes, it costs more to heat a large room than a smaller one due to the greater volume of air. The higher the ceiling and the larger the footprint, the more energy is required to raise the surrounding air to a comfortable level.

This increased energy demand translates to higher utility bills. The exact cost difference depends on factors like insulation quality, local energy prices, heater efficiency, and climate.

So, What is The Best Choice For You?

The best space heater for a large area with high ceilings depends on your specific needs.

If you prioritize energy efficiency and only want white noise, an oil-filled radiator like the DeLonghi is what I recommend.

For those needing immediate warmth with easy placement, an infrared model like the Dr. Infrared Heater is a good option.

If you require a heater for an exceptionally large space, the high BTU output of the Mr. Heater propane heater may be the best option.

Finally, always consider the heating element, safety features, energy costs, and heater capacity.
