Types of Large Room Heaters

There are three main kinds of space heaters which are ideal for large rooms: radiant, convection and combination.  These space heaters offer a different level of heating and different features.

Radiant Heaters

Radiant heaters are powered by electricity, fuel, or gas, and work by radiating heat outwards, usually in a 360 degree radius.  Some of these models, such as the Mr. Heater F270800, may be infrared models.  These models are great to put in the center of a room or social space to radiate heat evenly outwards and warm the entire space.

Convection Heaters

Convection heaters rely on the natural flow of air and the fact that hot air rises.  They suck in cold air and heat it before it is blown around the room.  This creates a circulation of hot air around the room and are much better at heating larger areas due to the flow of air.

Combination Heaters

Combination heaters are a combination of radiant and convection.  They radiate the heat  they produce but also use a fan to blow it around the room.  Combination heaters are an excellent option for larger rooms, but may cause some hot spots near the heater which can be dangerous.

Size and Setup

There are two important aspects that you need to consider when buying a space heater for a large room and this is size and set up.  These aspects will change depending on the area being heated and the person installing the space heater.

Size

The larger the area you want to heat, generally the larger the space heater you will need.  This allows the space heater to get heat around the entire area of the room.  Smaller space heaters are good for large rooms but perhaps more suited to houses rather than sites, as there will be more insulation to keep the heat contained.

Setup

The larger the space heater, the more assembly and setup is generally required to get it going.  This is fine for those who are used to a bit of construction but this may be difficult for someone buying a space heater for home use who has little experience.  Larger space heaters are also more difficult to use, so we recommend that if you are a beginner to large space heaters that you ask for assistance from an experienced or professional user.  This will ensure you get the best performance and the least hassle.


Portability and Mounting Options

Many of the smaller space heaters have the ability to either stand freely in a room or mount on a wall to provide heat from above.  If you are looking for a portable space heater, you may not want to mount it, but many of these options will offer a wall mounting kit just in case. If you are looking for portability so that you can move the space heater from room to room, it is better to look for a smaller and lighter space heater.  This will make it easy to carry the space heater around by yourself.  For portability, you should also look for a space heater which holds the propane tank inside the body of the heater itself.  This will save you having to move both the heater and the tank, then hook it all up again. 

If you are looking for a wall mounting option, perfect for a garage or construction site, there are so many options available.  Almost all space heaters will offer some kind of mounting functionality and will hold the propane tank within the body of the heater.  However, if you are looking for a large propane consumption to ensure a long lasting heater, you may want to consider an extension to the gas line to make sure the propane reaches the pilot light.


Thermostat

Not all space heaters come with a thermostat to allow you to decide the level of heat which enters the room.  This can make it difficult to maintain a level temperature and you may find yourself going back and forth to switch the heater on and off to ensure a level heat.  This can be annoying for most users, so if you are looking to purchase a new space heater and want little maintenance, we recommend looking for a model with a thermostat.

However, if you happen to buy a space heater without a thermostat, it is possible to attach one as an accessory.  This will allow you to track the heat of the room and change the temperature as and when you need to.  They control the pressure of the propane which reaches the heater to reduce the heat.   By controlling the heat in the room, the thermostat will help you to safe fuel and save a lot of time and effort trying to keep the room at a level temperature.  Instead of you having to manually switch the space heater on and off to maintain a comfortable temperature or save money, the addition of a thermostat simply does the job for you.


Useful Features of Large Room Heaters

Thermostat

Like we said, we highly recommend a space heater with a thermostat or to purchase an additional accessory.  These handy devices make your life easier as they control the temperature of the room without having to do anything manually.  They will also save you money as there will be much less wasted propane from using the space heater at its highest setting constantly.

Push Button Ignition

If you are looking for a space heater that is easy to use, consider a push button ignition function.  This will switch the space heater on in seconds so that you don’t need to be hunting for matches or trying to ignite the space heater using batteries.  This is great for both home and professional use to save you time and energy.

Built In Fan

A built in fan is a great feature for a space heater, especially in larger rooms as they ensure that the heat is properly circulated around the room and minimizes hot spots.  If you are looking for an even temperature, we recommend looking for a space heater with an in built fan or considering an additional fan to keep the hot air moving.

Safety Features

There are a number of important features which help to make space heaters safer for home and professional use.  We will discuss these below.


Energy Consumption & Costs

Depending on whether you use an electric space heater or a propane space heater, the energy consumption and cost calculations will differ. 

Electric Space Heaters

If you are using electric powered space heaters, the wattage of the space heater is essential in calculating the cost.  Another essential component of this calculation is the cost of your electricity. If you use a 10,000 kilowatt space heater such as the Dr Infrared Heater DR-PS11024 for 8 hours a day and one unit of electricity costs you $0.15, this space heater will cost you $1.50 per hour, $12 per day and $360 per month. This may change depending on the space heater you own and the area in which you live.  If you would like to calculate how much an electric space heater will cost you, here is a handy cost calculator you can use.

https://www.omnicalculator.com/everyday-life/electricity-cost

Propane Space Heaters

Again, the cost of propane heaters will change depending on where you live, as the local cost of propane may differ between states and cities. One gallon of propane contains around 91,333 BTUs, so if your propane space heaters goes through around 30,000 BTUs an hour, one gallon will last you for just over three hours. Another factor to consider in the cost calculation is how severe the cold will be that your space heater is trying to warm up.  If the space heater needs to move the temperature from -10 degrees Fahrenheit, this will take more energy and be more expensive than if it were moving it from 30 degrees Fahrenheit. The average cost for a 1,500 square room, which would require 1.5 million BTUs per month, based on the average cost of propane at about $2.86 per gallon, would cost around $57 per month in a mild climate.  A more severe climate may increase this cost.


Room Size

The size of the room will change the size of the space heater you require.  Particularly large rooms will need more BTUs than smaller rooms, and colder climates will also require more energy than milder climates. The chart below will give you a general overview of the BTUs needed per different room size.  However, if you would like an in depth calculation of the BTUs your room requires, there is a useful calculator here.

https://www.bestheating.com/btu-calculator
Area To Be Cooled (square feet) Capacity Needed (BTUs per hour)
100 to 150 5,000
150 to 250 6,000
250 to 300 7,000
300 to 350 8,000
350 to 400 9,000
400 to 450 10,000
450 to 550 12,000
550 to 700 14,000
700 to 1,000 18,000
1,000 to 1,200 21,000
1,200 to 1,400 23,000
1,400 to 1,500 24,000
1,500 to 2,000 30,000
2,000 to 2,500 34,000

Safety

When looking for a new space heater, one of the most important things to consider is safety.  As many space heaters burn propane, safety has to come first to ensure that there are no accidents or injuries. The first thing you want to make sure is that the space heater has been tested for safety.  All options on this guide have been factory tested and carry safety certification to ensure that they are of top quality and security.

The second consideration is what safety features have been built into the space heater itself.  Some of the best features are things like automatic switch off functions.  These functions will turn off the space heater when the pilot light goes out so the propane doesn’t continue to enter the room.  Other switch off functions will turn the heater off in case of falls or low oxygen in the room so that there is not an influx of carbon monoxide. A cool touch exterior is another great safety feature, which will protect you if you need to move the space heater or happen to brush past it. Many of the space heaters in our guide have these options, because we here at Surf’n’Buy know how important safety is for you.
