[earnist ref=”pursteam-elite-garment-steamer” id=”1818″]

The Duraflame Electric Infrared Quartz Fireplace Stove replicates the aesthetics of an actual fireplace but without the unsightly mess, especially during cleaning and maintenance. Setup of the heater is easy since the main unit is already assembled and all you need to do is to attach the legs, however placement-wise; treat this heater as same as an actual fireplace and place any flammable/combustible objects around 3 feet away from the unit; both the sides and front to avert any fire hazards.

In terms of safety, the Fireplace Stove comes in with a very unique safety control mechanism in which the heater automatically shuts down when it gets too hot thanks to its built-in thermometer. Take note though that when the unit shuts down frequently, you might want to relocate the unit to a plug with lesser draws on the same circuit.

In terms of usability, the Duraflame Stove offers simple controls but with some welcome additions wherein you can optimize the desired heat levels and provide an automatic shut-down function after 30 minutes of use if the heat has met your requirements. In fact, the heat that the stove provides is impressive but not that too hot to make your skin dry, it is hot but of the right levels.

The Duraflame Electric Infrared Quartz Fireplace Stove however while it is not a bad choice for large rooms, it tends to shine better in medium-sized rooms. The stovetop is a bit pricey as well. Pros

  • You can’t put display items on the surface because it heats up as well

Final Verdict: Pricey it may be, but the Duraflame Electric Infrared Quartz Fireplace Stove offers the same benefits as an actual fireplace but a fraction of the cost of getting a true fireplace to your home.

It is easy to set up and doesn’t eat up too much space once the device is up and running and has some tricks up its sleeve to provide excellent heat and at the same time; has countermeasures against some of the common problems seen in other space heaters such as overheating and plugs melting off. Such a shame though due to its pleasing design; if only the top surface doesn’t go hot, you can add some decorations to make it more attractive.

As said earlier, it ain’t a bad choice for large rooms but it tends to fare better when heating medium rooms.

3. DeLonghi HMP1500 Mica Panel Heater

You might mistake the next entry as a “piece of art” hanging on the wall and its none other than the DeLonghi HMP1500 Mica Panel Heater. This heater packs 1500 watts of heating power and is capable of providing the best room comfort.

Speaking of hanged or mounted on the wall, the DeLonghi Mica heater can be a great choice for rooms with a high ceiling.

The Mica-heating element can get hot very fast without consuming much power making it efficient in doing its job and if ever there’s a need for adjusting the temperature; the adjustable thermostat is there for that, with just the use of a knob on the side of the device.

Why or When to Use a Space Heater for your Large Room?

Before we would go further into this article; let’s get to know some very important factors on why or when would you need to use a Space Heater for your large room. First off, a Space Heater is considered an attractive choice to consider for heating, if you are only concerned about heating a single room and not the entire house. Or if it is too cold in one room and you just want to speed up the process so you can get cozier, faster. Space heaters are also ideal if you want to decrease your electrical bills since a centralized heating system can be quite expensive in the longer run.Space heaters come in various brands and models. It could be challenging to find the perfect fit for people with different lifestyle and needs. A portable space heater cannot only be great for lowering heating bills but at the same time, you can heat any room which you are currently using by just bringing them around the household!

What to look in a Space Heater for Large Rooms

Next up in this article is to know what you need to look for In a Space Heater that you will use for Large Rooms. As stated in the opening, you would want to obtain the right model so that your home will be properly heated. The first factor that you need to consider in obtaining a Space Heater is Power. If you want to heat a whole room then you need to measure its size; being, in general, is that 10 watts are enough to heat a single square foot of space so that means you need to find a heater that is capable of heating the entire vicinity of the room where it will be placed. Also, you want to ask yourself if you care about the amount of time it takes to heat up the room. If you enter your freezing cold room and need to be asleep soon you may want to keep in mind specific types of heaters that heat up quicker than others.Second is that you need to consider the available fuel options for your preferred heater. Heaters powered by propane tanks require a lot of attention hence aren’t a good choice for places with children. Gas heaters would require having gas lines installed in your household and might be pricey due to the installation costs; although they’re cheaper in the longer run. From the get-go though, electricity-powered heaters are the cheapest option for you to consider.A third factor to consider is the space; it all boils down to whether you need a surface wall heater for use in garages and workshops or perhaps a free-standing heater that has the added benefit of portability whenever it is needed to be transferred from one place to another. Try considering any of the heaters that come in with additional features such as built-in thermostats, adjustable fans, remote controls, timer and wheels and the like.Next, to consider are the safety features. Heaters should come in with a safety label so that you can be sure that the model has been tried and tested. Cool-touch exterior heaters come in with the advantage of not getting hot and become a fire risk. Other models come in with automated switch-off function whenever the heater’s starting to overheat. As for gas heaters, they have an automated switch-off feature whenever there is insufficient oxygen for the heater to use.

Type of Space Heaters:

Before we can go even further; let’s familiarize ourselves first with the different types of Space Heaters.

A. ) Radiant Heaters

Radiant heating systems heat a building through a warm element such as a floor, wall or an overhead panel and warms people and other objects in rooms rather than directly heating the air. The internal air temperature for radiant-heated buildings tend to be lower than that of buildings that are heated by conventional heating systems and that is to attain the optimal level of body comfort. The main advantage of radiant heating systems is that aside from the decreased air circulation inside the room; allergens are less likely to be distributed making them a very attractive choice for people who suffer from dust or pollen allergy.

B. ) Forced Air Heaters

In North America, this is the most prevalent type of heat-transferring medium. Often this is a centralized heating system which relies on air as the medium of transferring heat from one place to another. Forced Air Heaters tend to rely on a network of ductworks and vents as means of distributing the air but these are separate from the actual heating and air conditioning systems. The central heating system varies and can be either one of the following: Natural Gas/Propane or Coal heating system which relies on burning or combustion of fuel. Next, are electric-powered heating systems which rely on a simple electric element to heat the air. Third, is the Heat Pump which extracts heat from the environment either using the ground or the air as the heat source. Last but not least is the Hydronic coil which combines hot water with forced air delivery to create heat.

C. ) Convection Heaters

These heaters operate by air convection currents that circulate within the body of the appliance and across the heating element. The result is that the air heats up, becomes buoyant and quickly rises. A convection heater relies on either one of the three heating elements such as a hot water coil or a steam coil. Because they utilize natural ventilation; convection heaters tend to operate with minimal noise.

D. ) Radiators

Old-fashioned but still effect is what these heaters are best summed up. Radiators come in two variants; first up are the Steam Radiators which rely on boiling water to create steam which travels through pipes into the radiator which heats the room via radiation and convection. A little old-fashioned but still works. The other variation is a bit more modern which are Electric Radiators which functions almost similar to the classic radiator but with a twist.The radiator’s heater core is a metal reservoir that contains special mineral oil which doesn’t need refilling nor replacement due to its extremely high boiling point and heat capacity. This oil even in small amounts can emit high amounts of heat energy. Underneath that reservoir is a heating element that is reminiscent of that in electric stoves which heats the oil and warms the walls of the radiator causing the heat to radiate into the surrounding space. The common trait that these two shares though, is that they are both safe and low-maintenance heating options.

What type of Space Heater is best for large rooms?

Each of the mentioned types of Space Heater can be great in large rooms; it all boils down to preferences of the persons who are occupying the place however, Radiant and Convection Heaters tend to have an edge because first, Forced Air Heaters often have the requirement of having the presence of a central heating unit and a network of vents and ducts where the heated air will come out and in the case of Radiators; they rely on installed pipes where the heat travels through it but gradually becomes cooler as time passes, but lately there are now more portable variants but they heat up rooms in a much slower pace though. Radiant and Convection heaters, on the other hand, have a larger variety of models, they can be either be stationary which can be installed on the walls and the like or in some cases, can be standing models that can be positioned in an open space in a room.

Ways of Power a space heater for large rooms

There are two notable ways for Space Heaters to be powered up; namely through the use of Propane or any form of Natural Gases; or any related fuel sources and through Electrical means. Each one of them comes with their own set of advantages and disadvantages, so let’s take a look at them, shall we?

Electric Space Heaters

Electric heaters rely on an electric element that runs through the pipes. The electric currents will run through the element which heats it up. The current of electricity is then converted into heat energy and spreads through the radiator; emitting the heat energy into the area. This type of heater is considered as an attractive choice when one’s not too happy on turning up the thermostat but still wanted to keep the room of their choice as warm and toasty as much as possible. Pros:

  • Electric space heaters can be placed in unventilated rooms
  • Often are portable heaters
  • Usually utilizes ceramic heating elements to minimize fire hazards
  • You can use an electric space heater to heat up the room prior to using it.


  • A bit expensive in the long run, don’t be too surprised when you see your electric bill going up
  • Electric heaters require to be set up in the open; often away from other objects due to fire hazards.

Propane Space Heaters

Next up are the Propane Space Heaters which utilizes Propane, a very versatile source of fuel which is becoming an attractive alternative to oil, electric and even natural gas as a means to heat up a room especially during the colder parts of the year or in places where the colder seasons last longer than the warmer parts of the year. Often these type of space heaters are considered to be expensive at the first time but becomes cost-friendly in the longer run. Pros:

  •  Cost-effective; compared to electric-powered heaters. Propane space heaters cost less because the fuel is easy to obtain.
  • Low-maintenance
  • No monthly bills; the only thing that you will be paying for after when you get a Propane Space Heater and the Propane Tank at first, are the refills of the propane tank to keep it running.
  • A clean source of fuel


  • Propane is toxic; do not try to touch liquid propane as doing it so results in symptoms similar to Frostbite and ingestion of Propane is potentially lethal.
  • High flammability and pressure. The slightest leak or damage to the tank can be dangerous as Propane is highly flammable and the slightest damage in the propane’s containment tank can potentially end in an explosion.
  • Initial costs are expensive; you will need to invest a good amount of money for the heater and the first purchase of the Propane Tank.

How much does it cost to run a 1500-watt heater for 24 hours– Before we conclude this article, here’s a question that folks will be asking in regards to using a heater, how much will it cost to run one for around 24 hours. As you can see, the most frequent wattage available for a standard space heater is 1500 watts. Usually, space heaters would cost around $0.15 per kilowatt-hour, so you are looking at $3.60 per day assuming that you are running the heaters for a whole day. Take note though, the rates per kilowatt-hour could vary depending on your area and the electric company that you are paying and this is just a rough estimate.


– If you are to look for a heater that’s suited for a large room, I’d say the best picks are the Dr. Infrared Heater Portable Space HeaterDR-968 (1500-Watt) and the DeLonghi HMP1500 Mica Panel Heater because for the former, it is a small powerhouse that can rapidly heat up the room but try using whenever it is only needed as it can skyrocket your electric bills if you’re not watchful. As for the latter, the Mica Panel heater can operate in both large rooms and those with a rather tall ceiling but it is advised you provide additional support so that it can function at its best. As for the other heaters in the list, they’re still decent picks but as said in the case of the Mica Panel, I guess a little bit of additional support can make them perform decently in a large room. However, in the end, it all boils down to the preferences of the people who would want to use a heater for their large rooms. Just bear in mind of the factors and the types of heaters before purchasing one so that you will end up with the right heater for this upcoming cold season. Whichever choice you get it’ll be because you did your research, so congratulations and stay warm!
