This not only prevents serious accidents but it also helps in saving on energy bills. Similarly, the exterior never gets hot-to-the-touch.
Additionally, the heater comes equipped with a glide-pivot system so you can easily choose where you would like the warm air to be directed to. Besides, its space-saving design permits you to place it up against a wall to ensure it does not take much of your space.
The Lasko Cyclonic 758000 Ceramic Heater is a very capable indoor heater for large rooms in its own rights. Sure, it may lack some convenient features commonly found in high-end models like more heat settings and tip-over sensor but it does a great job at keeping rooms warm and cozy.
From afar you would easily be forgiven for thinking this is a safe. It is instead a top-tier indoor heater meant for use in large rooms. The box-like machine has a copper PTC heating element at its core which deserves heaps of praise.
What’s more, the heating element comes with an auto-reboot feature. This caters to situations where there is a power outage. As soon as the power comes back, the machine knows to get back to heating the room.
Also, there’s no need to curtail your kids’ freedom if they are running around while the device is working. The front grill cover may look dangerous, but it isn’t. In fact, everybody in the house can touch that grill cover without fear of getting hurt.
EdenPURE TS 1000 continually monitors temperatures, and with this, it ensures the PTC remains within acceptable heating limits. That said, you will be the one to choose the temperature you want by selecting one of two power settings. Also, the temperature range stands at 40 F to 90 F.
Yet again, we find the indoor sensor has another safety feature in the tip-over sensor. This might be handy in cases of accidents. We should also mention that you will control this heater from anywhere in the room with a remote.
Furthermore, reasons to buy more than one unit have been eliminated by the wheels included. As such, it is entirely within your rights to drag the machine from room to room even if it is too heavy to lift.
You get heating and the peace of mind that comes from the various safety features when you buy this heater. The wheels perhaps are even more critical as they allow you to take the heater with you to any room you decide to stay in.

Things to Сonsider
These heaters come with a propane tank. All you need to do is buy a refilled propane gas tank for them to work. Fortunately, these (tanks) are readily available in most stores. Once you have the tank in place, the next step is to connect it to the heater. The heater will automatically start to function when you turn on the valve and ignite its element. The main advantage to using this unit is that safe propane heater indoor use is never really a major issue.
It burns clean and is way better than any other type of fossil fuel. Above all, this by-product of natural gas reduces overreliance on petroleum products yet still supplies you with adequate heating power. On the flipside, though, you need to keep replacing the tanks with refilled ones in addition to being on the lookout for any accidental gas leaks.
Corded electric heaters are highly popular because they’re pretty convenient to operate. They don’t require any special fuel. Likewise, no special lines or tanks are required to get them working provided there’s power.
Compared to propane heaters, these ones are highly portable. On the downside, though, these units can run up your power bill. That’s of course in addition to the fact that they’re limited on portability. You can only place an electric heater a short distance away from a power outlet unless you invest in an extension cord.
If you don’t want to struggle with power bills or the hassle of acquiring propane gas, solar-powered heaters might be your best bet. These units operate by converting the rays of the sun into usable power.
Ordinarily, if you live in a place that has long and cold winters, you might end up spending over $1,000 in natural gas, kerosene or oil alone, per year. And while solar-powered heaters aren’t that reliable especially during cloudy days, you can use them to supplement your heating needs.
Pundits argue that you can save more than 30% worth of power cost per year by investing in a solar indoor heater. Of course, the savings may vary depending levels of sun in your climate as well as the size of your home.
Battery-operated heaters are not as popular and that’s because battery energy is quite limited. As such, some reviewers have even claimed that battery technology doesn’t work for heating home. The reality is that battery-powered heaters exist only that they are best used for emergencies.
That said, this technology still has a long way to go – and who knows?
We might end up with some more powerful battery-operated heaters one of these fine days.
Also known as paraffin heaters, these are typically tiny heating devices. They’re known for producing supplemental heat, especially during power blackouts. Also, thanks to their tiny design, kerosene heaters are a perfect find for camping and bugging out missions. As if that’s not enough, these heaters are designed to operate like large kerosene lamps.
They have a wick which is made from fiberglass. This wick draws kerosene through capillary action. All you need to do is light this wick to initiate a process known as gasification. Eventually, this raises temperatures around the room. That said, you would still need to spend some money on buying kerosene from time to time. It’s also worth noting that kerosene is a carbon-emitting fuel and so it should be used sparingly.
Does this option sound familiar?
Wood is one of the few sources of power that straddle the thin line between renewable and non-renewable energy. As you know, it is always possible to regenerate trees by planting more of them. However, we only need to ensure that the rate of consuming wood is slow enough so we don’t deplete our forests.
In other words, if done properly, indoor fire heating has the potential to be carbon-neutral. All you need to do is find split wood and simply light up the wood within the designated area. It’s usually recommended to have the fireplace fitted with a chimney or vent to help in managing the smoke, though.
Diesel is renowned for its ability to convey great levels of power. It’s no wonder it’s commonly used in running heavy machinery.
But how good is diesel when it comes to indoor heating?
First off, diesel is quite affordable and in fact is one of the most common sources of energy around the world. You simply need to find a diesel-powered machine and top up the fuel.
Modern technology has made it possible to design small and portable diesel-powered heaters. Small qualms with diesel-powered machines would be that they’re difficult to maintain in the long-run. For instance, you’d need to keep changing the fuel filters among other consumables from time to time. Otherwise, they can always be a reliable source of power.
Maybe you’ve heard your electrician talking about heating elements only to be left wondering, what on earth are those?
Well, to break it down to you, heating elements are simply units which convert electric energy into heat energy. They’re typically found under the indoor heater cover. There’s a whole load of scientific research behind heating elements, but for now, we’re better off focusing on the different types that exist.
Ceramic material is what is known in the world of science as a semiconductor. One cool feature of these heaters is that unlike traditional coil heaters, these ones bear no risk of burning. In fact, they are so called because they use a number of plates which absorb heat and release it to warm the surrounding air.
This special technology makes them reliable for heating small rooms, unlike models that use ordinary coil heaters. And there’s more – ceramic elements are highly energy-efficient owing to their ability to combine convection and radiation heating processes.
Infrared technology is the buzzword in the world of indoor heating technology. This is because unlike other systems which work by heating the air particles, infrared rays are transferred directly to your body. That’s pretty much how the sun rays work.
So, with infrared, you get an opportunity to heat up any room while being more energy efficient. Best of all, these heat rays are safe for you and anything else that may absorb them.
Oil Filled Heater
What’s the difference between an oil filled heater and a diesel powered one?
You might be wondering. Well, the difference is that the former contains oil but doesn’t consume it. It merely uses oil as a heat reservoir. It is made up of different columns which come with cavities that house the oil.
This oil has a high heat capacity which allows it to accumulate as much thermal energy as possible for purposes of warming your room.
How to Choose the Best Indoor Heaters for Large Rooms – Buyer’s Guide
As power bills skyrocket and winters get colder, you’re better off finding a cost-effective way to heat your home. The good thing about going for a space heater is that it allows you to keep your thermostat operating at a lower setting. This also adds targeted warmth to particular rooms.
For instance, you can add warmth to the living room so everyone takes dinner in peace and so forth. We’d recommend you use this guide so you can find a heater that best suits your needs.
The battle of heating technology pits convection heating against radiant heating and Micathermic heating. Convection heating is the most common method of keeping rooms warm. It works by warming the air. Most units that rely on this technology come with a fan. The job of the fan is to circulate the warm air across the whole room. In general, this type of heating technology is best suited for heating large rooms.
Ceramic space heaters are also a type of convection heating machines. Their heating discs are hidden within the body and that, therefore, keeps them cool to the touch. It’s for this reason that most people use them for heating spaces with pets or children’s bedrooms.
Radiant heating, on the other hand, works best when spot heating is involved. Unlike convection heaters which require a few minutes to warm up the air, radiant heaters deliver near-instant warmth. For that reason, it’s not unusual to find these heaters being placed under office desks to keep one warm as they work. Another unique characteristic of radiation energy is that it tends to deliver soft and consistent warmth.
The last example of indoor heaters is one that uses Micathermic heating. This unique technology uses a combination of convection and radiation energy. Some of the heat radiates from its panels and reaches you directly. At the same time, this machine uses convection to heat up the air around your home before re-circulating it.
One unique attribute of Micathermic heaters is that they’re fanless. As such, they don’t re-circulate dust or any other allergens. For this reason, they also tend to be quieter yet highly effective and safe.
Different heating styles
Space heaters are designed to meet different needs. So, whether you want a floor heater, space heater, baseboard heater or wall heater, there’s certainly something for everyone. Floor heaters are particularly popular as they can be placed on the floor and heat up the entire room. They, therefore, feature a vertical, space-saving design and fans which spread the heat across the rooms.
As for space heaters, you only need to place them either on the floor, table, or nightstand. In a nutshell, space heaters work best when placed on anything that enables them to generate focused heat. Lastly, wall heaters are recommended for basements and bathrooms while baseboard heaters are typically placed under windows.
The size equation
One important fact to always keep in mind is that size is a huge factor in home heating. For instance, trying to heat up a 150 square feet room with a 500-watt heater might be unrealistic. Likewise, there’s no use in buying a 1,500-watt machine only to use it in a 30 square feet cubicle. The rule of the thumb is to always strike a balance so you don’t end up generating too much energy for no reason.
How to Use
Thankfully, most indoor heaters aren’t complicated to use. Some, like electrical ones, require you to fit them on an electric plug and simply turn the switch on. Others like propane powered ones operate provided you’ve connected them to a source of propane and switched the valve on. Kerosene heaters need to be lit up so the wick can start to generate energy.
In a nutshell, there’s no single way to use a home heater. You need to start by understanding the uniqueness of your unit before putting it to use. Most importantly, you can always refer to the user manual or contact your supplier for further assistance.
Care and Maintenance
Statistics from the EPA show that neglect is one of the leading causes of heating system failures. Just like your car, your heating system needs regular check-ups and tune-ups. Without taking such measures, you might end up incurring more expenses on unnecessary repairs. Instead of waiting until it’s too late, we’d recommend taking a few cautionary steps which may include:
Sticking to a regular maintenance schedule so tiny issues are dealt with before they spiral out of control
If you’re in doubt on how to operate any aspect of your heater, be sure to consult the user’s manual
It’s important to vacuum the element every so often to remove any dirt that might build up over time
If you own a gas or diesel powered system, it’s important to clean or replace the filter system when necessary as leaving it to clog up may reduce your heater’s efficiency
For heaters with fans, a thorough inspection of it may help avert possible malfunction
Never start any cleaning and maintenance of your heater before confirming that it has been switched off and disconnected from its power source
All heater elements tend to heat up over time, so always proceed with caution when coming in contact with the element
Avoid, at all times, placing the heater on a flammable surface e.g. wooden or bamboo floor
Make sure your heat is placed on a level surface which should also be hard and stable
Keep your heater unit away from children’s reach
Never compromise on your safety, only use a heater that has been tested and proven to work
If using a wood, diesel or paraffin heater, it’s imperative to invest in a carbon monoxide alarm as well
Most indoor heating options come with a 10-year warranty which is mainly limited to parts. That said, there are some manufacturers who offer up to 20 years of warranty while a few others offer 5 and even 3 years packages.
We’d recommend going for the best warranty package available so you can save more in case of a malfunction or flaw.
A simple way to estimate the potential additional cost of running an electric heater is by first checking the cost you pay per kWh in your region. For instance, if your last bill was $300 for 2000 kWh, then it’d be correct to say that you paid 15 cents per kWh. From that point, all you need to do is multiply that figure with the wattage of your machine and .001. For instance, if your heater is a 1500-watt unit you simply need to do as follows:
1500×0.001×0.15 = 0.225 cents per hour.
So, if you operate your heater for 10 hours per day, you’ll pay $2.25 per day and approximately $67.5 per month.
Try to reduce temperature loss from inside your house by insulating your windows and walls. That will enable you to use a lower heat setting which will, in turn, put less strain on your machine. Lastly, be sure to switch off your heater when not in use.
It’s important to clean your heater surface regularly by wiping it (avoid using water). However, dust is a normal part of life and it’s not unusual for it to accumulate on your heater.
Our best pick is the LifeSmart Large Room Infrared Heater. We like the fact that it is well built and can be remotely operated. And in case power consumption is a worry to you, you’ll be glad that this machine has adjustable heat settings.
For instance, you can use the eco-friendly 500-watt setting to raise the room temperature slightly. That said, you might want to keep it out of your bedroom if you’re extra sensitive to noise as its fan is quite powerful.
The second runners-up position would go to the Delonghi HMP1500 which only misses out on the top position because it takes a bit too long to get the whole house warm.
So that’s pretty much it, a comprehensive list of indoor heater reviews. All you need to do is find one that best suits your needs and start making your home a haven of warmth. Of course, you’re better off insisting on the best indoor heaters for large rooms to eliminate any possible disappointments.
