6 Most Energy Efficient Space Heaters – (Reviews & Guide 2020)

Space heaters are a popular choice when it comes to adding supplemental heat to your home or creating some warmth in a garage or workspace that would otherwise be too cold to use in the winter months.

When you buy your space heater, it is important to know whether or not it will be energy efficient when you use it or if it will be a waste of money for one reason or another.

Space heaters that are inadequate will result in a waste of energy as the heater will need to be turned on for longer and even then, it may still never heat the room. On the other hand, if the space heater is so powerful that you have to open the windows to let some air in, this may again be uneconomical and inefficient.

Check out these reviews and our helpful buying guide so that you can find the most energy efficient space heater for your needs.

Buying Guide: Choosing An Energy Efficient Space Heater

Most Energy Efficient Space HeatersBy choosing the right size of heater for your Home, as well as the right fuel type, it is possible to find a high-efficiency heater that will save you money every month on your energy bills.

Things to Know to Choose The Most Efficient Space Heater

  1. Determining the Right Types of Fuel to Use

    When you choose your heater, you will have a variety of fuel types to choose from. You could have a:

    • Electric heater – these heaters use the electric supply that you already have in your home. They could be integrated into your central heating system, or they could be used on their own.
    • Natural gas heater – a natural gas heater uses the supply of gas you have in your home. This tends to be quite a cheap way of running the heater and it is convenient as these eaters can be easily installed. You may like: Gas Fireplace Inserts
    • Kerosene heater – kerosene is a cheap fuel and it is a little safer to store than propane. Kerosene heaters can be incredibly powerful so they are popular amongst those who need heat in their workplace.
    • Propane heater – propane is a very cheap fuel. Propane heaters can be used indoors or outdoors.
    • Pellet fuel heater – pellet fuel heaters are incredibly powerful and they can heat your entire home. The pallets themselves are cheap to purchase and the heaters generally tend to burn them efficiently.
    • Oil filled heater – oil filled heaters are usually powered by your electric supply. They use convection currents and as a result, they stay warmer even after they’ve been turned off.
    • Hydronic heater – hydronic heaters are warmed up by the main boiler that you have in your home. Hot water is passed from the boiler to the heater and this warms up the heating appliance.

    With so much choice when it comes to choosing an energy source for your home, you will be able to weigh up the costs of using each type of fuel with your heater.

  2. What Types Of Heaters Are Available?

    Just like the range of fuel choices that you can choose from, there are also a great variety of types of heater that you can choose.

    Hydronic and oil filled heaters tend to be flat with a wide surface area. They take a long time to heat up and as they use convective heating methods, it can take a while for their heat to be dispersed around the room. The great thing about these kinds of heaters, however, is that once they are turned off, they still retain heat for some time afterward.

    Propane heaters can be used inside or outside. If you do want to use propane heater inside, however, you will need to ensure that it is designed for safe indoor use before you purchase it. You should never use a propane heater that is designed for outdoor only use indoors. Propane heaters can use radiant, convective or fan forced heat depending on the kind of environments that you want to warm up. Patio heaters usually run on propane fuel.

    A kerosene heater will be capable of producing huge amounts of heat. You can often find that they are sufficient to heat up your entire home with ease. You would also be able to use them to heat a garage or warehouse. You should ensure that you’re very careful when using one of these heaters however as they need to be well ventilated and you should ensure that you follow correct safety procedures.

    Electric heaters come in a variety of shapes and sizes and are usually designed for indoor use. They could be mounted to a wall or ceiling, attached to the baseboard or they may even be portable. There are a huge number of these heaters that you can choose from. You may also like: Best-Selling Electric Baseboard Heaters


The Top 3 Things to Consider When Buying The Most Energy Efficient Space Heater

  • The first thing that you will need to do when you are looking for the most efficient heater for your home or workplace is to measure the space that you have to heat. If you buy a heater that is too powerful for the room that the heater is in, you’ll find yourself opening windows and doors to let some cold air in to regulate the temperature. On the other hand, if the heater is insufficient for the area that you have to heat, the heater will remain on for a longer period of time and may never heat the space enough to have a great impact.How To Find The Most Energy Efficient Heater
  • Once you know how much space you need to heat, you will need to look at the heaters that are available to you. Check how efficient they are by trying to figure out whether they will be large enough for your room.
  • Once you have a shortlist of heaters, you will need to work out how much fuel you will need to use to power them. There is a simple calculation that you can find online to work out roughly how much fuel you will use whilst the heater is running. Make sure that the fuel type is available in your area and that it is available in an ample supply cheaply.


How to Use Your Heating System Energy Efficiently

How to Use Your Heating System Energy Efficiently

  1. Choose Your Heating Method
    The first thing that you will need to do in order to use efficiently your heating system is to decide whether you need all of your heaters on in your home simultaneously, or if you only need to heat one room. If you are only spending time in one room, for example, when getting ready for school or work, or if you’re relaxing in the evening, you could use a supplemental heat source and turn off your full central heating supply. This will ensure that you are only paying the energy bill to heat one room instead of having to heat up your entire home.
  2. Use Heating Controls
    There are a few different heating controls that you can use. You can either have these fitted to your main central heating system, or you could choose heaters that have them on when you purchase them. The main controls include:

    • Timer
      You can set the heater to turn on or off at certain times of the day to coincide when you will be home and to conserve energy.
    • Room thermostat
      When you set a room thermostat, it will measure the temperature of the room and will control your heating system depending on how warm or cool the room is.
    • Programmer
      The programmer will allow you to not only set the temperature of the room or the timing of the heating system, but it will let you choose different temperatures throughout the day and different times throughout the week. This is especially useful if you are at home more on the weekends than you are during the week for example.
    • Thermostatic Valves
      These are fitted to your radiators and they can allow you to control the temperature of the radiator in each room. You could even turn off the radiators altogether if you wish.
    • Smart Heating
      This is a very modern way of controlling the heating in your home. You will need to install an app on your mobile device and you can then control your heating at home wherever you are in the world.
  3. Using A Room Thermostat 
    Room thermostats are still one of the most common ways of controlling space heaters throughout the home. If you’re unsure of how to get the most out of your heater, the best thing to do is set the thermostat to around 85 degrees Fahrenheit and then to increase it a little each day until you’re happy with the temperature. You should be sure to regularly check the thermostat to see that it is not being obstructed. The thermostat has a temperature sensor in it that works by detecting the temperature of the surrounding heat. If something is obstructing the thermostat, it won’t operate correctly and you could end up wasting energy.
  4. Zone Heating 
    When you need to warm up a room a little more or if you simply want to heat up a small area of your home or workplace, you should consider using zone heating. This will involve getting a portable heater that suits your needs best and using that to provide heat for just one or two rooms instead of needing to have the entire central heating system on at once. You could also simply isolate the radiators at home that you don’t wish to use and just have the radiators on in the rooms that you are using.
  5. Insulation 
    It is not enough that your heating system is powerful enough if your home itself is not energy efficient. You should check to see if there is adequate insulation in the walls and the roof of your home so that your home will keep the heat in. Another thing that you should do is consider installing double glazed windows if you only have single panes at present. Windows that only have one single pane will simply allow a lot of heat to escape whereas getting double glazed glass will mean that you can enjoy more consistent heating and a warmer home.
  6. Time Your Heating Right 
    When you are planning your home’s heating schedule, you should think about when you need the heating to be on. When you are getting ready for work or school in the morning, you will predominantly want to spend time in the bathroom and perhaps the kitchen to get your breakfast. In the evening, you will spend more time in the living room and then, later on, you’ll want your bedroom to be toasty and warm when you go to bed. If you have adequate timer features around your home, you should be able to program all this in so that you can enjoy a well-heated home without wasting any heat or energy in the process.


Tips for Positioning Your Heater

Energy-Efficient-Space-Heater-reviewsYou should bear in mind that not all heaters are suitable for use in all areas.

If you buy a kerosene heater, for example, you will find that it is dangerous to use these heaters in very confined spaces, such as a single room in your home with the doors and windows closed.

If you wish to use an outdoor heater close to your home, you should make sure that it is not placed near any windows or doors. Even though the heater will be outside, it could still blow toxic gasses into your home.

There are plenty of garage heater types available for construction sites, garages, and workshops. You should ensure that they are suitable for indoor use and check how they will be mounted. It is not a good idea to have a portable heater a workspace, as it may be knocked over easily. In these kinds of areas, it is a far better idea to choose a mounted heater for safety.
