Before You Buy; Important Energy Saving Factors To Consider

Before you step out to make a purchase, it is important that you are familiar with the various features that promote energy efficiency in your space heater. Here are some features to consider

Programmable Thermostat: A thermostat is one of the most important features that determine how your heater generates and manages heat.

A heater with a programmable thermostat will remain at the room temperature that you have programmed it to maintain.

Once that temperature is attained, the unit will go on or off on its own to maintain your room at a comfortable temperature while saving energy in the process.

Auto Or Eco-Mode: not every heater comes with these features, but finding a heater that comes with an Eco-mode can help you utilize energy the best way possible.

With just a push of a button, your heater will select between high or low fan speed and operate at an appropriate heating level to maintain an optimum set temperature.

In some cases, an eco-mode helps your heater reach optimum temperature faster and will kick off the moment this designated temperature is attained.

Multiple Heat Settings: when saving energy is the goal, it is important that you find a heater that allows you to vary heat settings.

Usually, most heaters for bigger rooms either come with multiple heat setting or a programmable thermostat.

But some heaters have both features and going for an option like that will be a great choice.

Programmable Timer: what happens if you happen to sleep off while the heater is on or you forget to turn off your unit when you leave home for work? An automatic timer that shuts off the unit will come I handy in this situation.

It allows you to specify how long you want the heater to stay on. in some cases, you can also set the timer so come on by itself at a particular time.

This way you can set it up to come on right before you arrive from back home from work or any other way you prefer it.

Buying Guide: Choosing  The Best Energy Efficient Space Heater

Types Of Space Heaters Based On Fuel Type

Space heaters come in different varieties and one of the major differences is in how they are powered.

Since energy efficiency depends to some extent on the fuel being used, it is important to get familiar with the various types of heaters available.

Electricity: electric heaters are among the most popular types of heaters out there. They work as independent heating units but they can also be installed on a central heating system.

Electric heaters are designed mainly for indoor use. They come in different sizes and shape and their energy efficiency varies from one type to the other.

Some of them are wall-mounted but they can also be mounted on the ceiling or attached to a baseboard.

Natural gas: Natural gas is another possible fuel used in space heaters. Because of how cheap and common gas is, it is one of the most economical options you can go for.

Natural gas heaters are also quite easy to install.

Kerosene: this is another cheap fuel that is used to power space heaters. Generally, Kerosene heaters are considered more powerful compared to others.

Thus they find more application in industrial or workplace settings or for heating up entire homes because they can produce high amounts of heat.

However, kerosene heaters require good ventilation and adequate safety procedures must be followed in installation and use.

Propane: propane is another popular and cheap fuel used to power heaters.  Propane heaters are suitable for both indoor and outdoor applications, although those used indoors are designed specifically for the purpose and are installed differently.

Propane heaters are commonly used as patio heaters and other outdoor applications. They transmit heat through radiation, fan forced heating or convection.

Pellet fuel: Pellet fuel heaters are popular for being quite strong. The more powerful ones can heat up an entire house. In addition to being strong, pellet fuel is incredibly cheap and they burn quite efficiently.

Other Types Of Heaters

Oil Filled Heaters: some people might find the name a bit confusing, but oil filled heaters are not fueled by oil. Instead, they are powered by electricity.

The oil they contain is heated up when you switch on the device heat is transmitted through it.

Although oil filled heaters take a while to heat up, they actually retain heat a lot longer than other types of heaters. In fact, they are considered to be among the most energy efficient space heaters out there.

Hydronic heaters: Hydronic heaters are powered usually attached to regular boilers in the house.

Like oil filled heaters, they transmit heat through a fluid which in this case is hot water.

They take a while to heat up as well but they also have impressive heat retention ability which makes them quite efficient as well.

Infrared Heaters: Unlike most of the other types of heaters that heat up the air first, infrared heaters don’t work that way.

Instead, they heat up objects or people in the room first and the air is only heated up later if the heater runs long enough.

The heat generated is transmitted in the form of rays. It follows a straight path and will stop once it encounters an obstacle. Infrared heaters are also called spot heater.

If you are looking for any heater that will deliver instant warmth in a small space then an infrared heater should work for you.  In terms of energy efficiency, there are some limitations.

The most obvious is the fact that heat dissipates as soon they heater is turned off which means you have to keep the heater on for longer.

However, infrared heaters are still considered to be quite economical mainly because they wasted less energy compared to regular convection heaters.

Ceramic heaters: Ceramic heaters are usually made exclusively of ceramics and aluminum. The baffles are made with aluminum while the heating elements are made with ceramics material.  They are usually small sized but give out an adequate amount of heat to warm moderate to large sized rooms.

Convection heaters: Convection heaters don’t have fans which mean heat circulation isn’t by blowing air around.

Instead, heat circulation is through convection. This mechanism of heat circulation has a lot of obvious advantages.

It is perfect for people with allergies or any type of breathing difficulty since no fan means no particles are blown around. It also doesn’t leave the air dry like regular heaters.

It can deliver quick heat to a room without eating too much into your electricity bills. There is also the issue of noise which is another problem with using heaters with fans.

The only downside to using these types of heaters it the fact that they are don’t retain heat for long as they cool off really fast once they are turned off.

How To Find The Most Energy Efficient Space Heaters?

It’s a good thing that you already know that you don’t want just any type of heater but an energy efficient one.

This way you are not simply shopping for heaters but your efforts are directed towards finding the ones that cost you least to use and maintain.

Measure the size of the room: let’s begin with somewhere close to home before you step out to check out heaters or get on that computer to check online, it is important that you know the size of the room you intend to warm up.

Buying a heater that is too small means your room you will not be getting as warm as you want it to be.

It also means it has to stay on for a longer period for it to perform up to par which means more energy will be consumed in the long run.

On the other hand, going for a heater that is too powerful for the size of your room will be a total waste of time.

Consider your options: as mentioned there are a lot of options to choose from when it comes to efficient heaters for your home.

Using the information you have about the size of your room, you can easily calculate how much heat the heater you want to buy will have to generate.

This way you can narrow down your options.

Determine The Fueling Options You Want To Go For: we have discussed some of the most popular fueling options for space heaters. You need to consider which one is most commonly available around you as well as how cheap and ample in supply it is.

Tips To Improve The Energy Efficiency Of Your Heating System

Finding an energy efficient heater to help save utility costs is a great idea.  However, even with the most energy efficient space heaters out there, you might still end up wasting more energy than you want to because of how you make use of your heating system. There are simple tips and tricks that can help you get the most of your heaters and reduce energy costs. These include:

Tip 1# Zone Heating

Most of the times, all you want to do is get a little area of your room, or just a single room in your home warmed up enough for you to conveniently stay in it. This is where zone heating comes to play.

Instead of turning on the central heating in your home, you can get yourself a portable heater that will provide supplementary heat to that specific area of your home you need it the most.

Such a heater should be portable and easy to transport, this way it will be able to cover multiple rooms depending on where you are making use of at a particular time.

Another alternative to this is to get your central heating wired in such a way that you can isolate specific areas of your home.

It works the same way as using the supplementary heater and you won’t have to turn the heat up in areas of your home where you won’t be making use of.

Tip 2# Get Heating Controls

Being able to regulate how much heat you are making use of in your home is important for energy efficiency.

One way to ensure total control over your heating is to use heating controls. You can either buy a heater that has inbuilt controls or simply have this fitted into a central heating unit.

Here are some important controls you should consider:

  • Timers: timers determine when the heater should turn on and off. If you have a stable schedule, you can time your heater to stay off when you are not at home and come on just right before you arrive at home. This way, you come home to a crisply warm house and you would have conserved Energy during the day.
  • Use a room Thermostat: A room thermostat measures the temperature in your room and controls how the heating system works based on this. You will be able to set an optimum temperature and the heater will turn on or off based on this temperature.
  • Use a Programmer: Typically, a programmer combines the work of a timer and a thermostat. But much more than that, it also allows you to set specific temperatures for different times of the day. This works great especially during times when you spend a lot of time at home.
  • Thermostatic Valves: another alternative is to have a thermostatic valve installed into your radiator. This allows you to control the radiator temperature for each of your rooms or turn the heater off entirely if you want
  • Smart home devices: Smart home software and apps like Alexa are making it more and easier to control how appliances work in your home. Once installed you will be able to control your heating from wherever you are using your mobile device or simply speaking out commands.

Tip 3# Insulate Your Home

Consider this, maybe the reason you are spending so much on heating up your home isn’t because of the appliance you are using but because your home itself isn’t designed to be energy efficient.

Without sufficient insulation in your roof and walls, there is a good chance your house will be letting all the heat out instead of keeping it in.

This is why you should consider investing a little more in insulation fixtures for your home.

For example, double glazed windows are more effective at conserving heat than single pane ones.

With features like this, you can further insulate your home and keep it warmer for longer.

Tip 4# Create A Heating Schedule

If you are someone good with keeping up with plans and schedules, then you should consider this option. You can time your heating to suit your habits and promote efficiency. The time spent at home in the morning is typically spent in places like your bathroom getting ready for work or in the kitchen preparing breakfast. At night, you are more likely to spend the time in bed, you can program your home heating on a schedule that coincides with your personal schedule this way instead of wasting energy by heating up your entire house.

Tip 5# Dress Up

One simple way to cut down on how much you have to spend on heating is to dress up for the weather. This might seem insignificant, but simply putting on your favorite sweater and socks can reduce how much you will need that heater after all.

Frequently Asked Questions

How To Determine How Much You Spend On Heating?

It is important that you are able to calculate how much your heating expenses will be if you purchase a particular type of heater.

To calculate this you need to know the power rating on your heater, how long you run it as well as the Kilowatt rating in your home.

For example, if you buy a 1500 watts space heater, here’s how to calculate how much you spend on it.

First, begin by converting the power rating to Kilowatts since the electricity rate is calculated in Kilo-watt hours. To do this divides the power rating by 1000.

This gives you 1.5. Multiply this figure by the number of hours you run the heater per day then by the number of days in the month. You can then multiply your answer by the kWh rate on your electricity bill.

This gives you an estimated amount of how much It will cost to use your space heater per month.

What Type Of Heater Is Recommended For Heating Up The Whole Room For A Short Period Of Time?

As discussed, your choice of the heater based on the mode of heat distribution is between convection, heaters, radiator heaters or fan heaters. The type of heater you go for depends to a large extent on what you need the heater to do for you.

If the intention is to warm up an entire room for a short period of time, the most energy efficient choice will be a convection heater.

A convector heater warms up the air around it really fact and circulates hot air evenly around the room which makes it a great choice for this type of heating compared to other types of heaters.

Usually, a convector heater takes some time to work to its full capacity. However, it also comes with a timer or thermostat which helps to automatically switch off the unit once an optimal temperature is reached.

What Type Of Heater Is Best For Spot Heating?

If you are looking for heater suitable for zone heating or spot heatings (basically just a quick blast of warmth) then you should go for a radiation or fan heater. These types of heaters are best suited for heating up a small area of your room for a short time period.

They do not heat up the air as convection heaters do, instead, they transmit heat in using electromagnetic waves the way the sun heats you the earth.

Radiation heaters or fan heaters are not effective for warming up a whole room and using it for that purpose will not be economical.

In most case, they also don’t have thermostats which means you might have to manually monitor to prevent wastage of energy.

Infrared Vs Ceramic Heaters. Which One Is Better?

This is one of the most popular questions users ask about heaters.  Infrared heaters and ceramic heaters are classic examples of radiation and convection heaters respectively.

These are the two common types of heat distribution system used in heaters. The basic difference between these two is in how they transmit heat.

Convection heater warms up the air closes to the heater and circulates it while radiation heaters warm up objects in their paths directly.

Generally, in terms of energy consumption efficiency, most experts consider infrared heaters more efficient than ceramic heaters.

But this isn’t to say that overall infrared heaters are better than ceramics in all cases.

In fact, the rule mostly applies to zone heating when you will be spending a long time in a specific area of your room.

For a more room-wide warm-up effect, the ceramic heater which uses convection current is a better alternative.

Also, infrared heaters operate noiselessly compared to ceramic heaters.  They are also better in terms of how they affect overall health since they don’t mess up with the air in your room.

However, infrared heaters get too hot to touch when in use. Also, they lose heat almost immediately which sorts of counters their reputation of energy efficiency since you has to keep them on as long as you want to stay long.

They also emit a bright red glow which many might find uncomfortable to have in a room while sleeping. 

Conclusion

As far as the efficiency of heaters is concerned, there are a whole lot of factors to consider. First, the power rating of the specific heater you are going for is really important.

Additional energy saving features like thermostats, timers and so on will also be important in determining how efficient the heater is at managing heat energy.

But much than the features on the heater itself, you also have to consider your purpose for purchasing the heater since different types of heaters will have varying efficiency depending on how they are used.

Finally, to get the best from your heater, there might make some lifestyle changes and make some simple adjustments too.

This way, after selecting from our list of best energy efficient heaters you will be able to better maximize it effectively to keep you warm and happy on cold days and nights.
