What is a Space Heater?

A space heater is the most suitable heater you´ll find to heat a single, small area. It is an efficient way to heat a chilly space for a short period of time. In contrast, a central heating system is used to heat many areas. A space heater is a good option when a central heating system is not completely effective in heating a specific space in the coldest time of the year. You can choose between different types of heaters.

Space heaters are powered by electricity or by petroleum oils like propane, natural gas, fuel oil or wood pellets. Although, the ones powered by electricity are very efficient when it comes to warming a room, they will make you spend some money on electricity bills.

Different space heaters excel at different tasks and the most energy efficient one depends on how or where you´re going to use it. In terms of technology, you´ll find the convection heaters, the infrared heaters and the micathermic space heaters. They come in different styles and designs to meet your heating needs and expectations.

Energy Efficient Space Heaters vs. Normal Space Heaters

Energy efficiency is a measurement for the quantity of energy used to power a space heater compared to the energy that it produces. Heat is measured in BTUs (British Thermal Units) and getting to know the energy that is produced for a certain amount of input energy is key when buying a heater.

Energy efficient space heaters will make you save money and will heat a space more effectively as opposed to normal space heaters. Nowadays, energy efficient space heaters are all about saving as much energy as possible and heating a room as effectively as possible. Power consumption and cost are very important to consumers, that is why normal space heaters are losing track in the market.

Energy efficient space heaters offer multiple heat settings and multiple power levels. These levels are measured in watts, amps, or BTUs. The higher the heater´s BTU rating, the better its performance. You can calculate using this formula:

Heater Wattage Rating X 3.413 (the number of BTUs that equal 1 watt) = BTU Output

A BTU (or British Thermal Unit) rating is useful when comparing the energy output, because BTUs measure the heating capacity of various fuels and heating units, that is why they´re a useful rating when comparing the energy output. For example, an 800-watt heater would deliver 2,730 BTUs and a 1,500-watt space heater would produce roughly 5,120 BTUs of heat. Energy efficient space heaters are generally more expensive than normal space heaters, but the market is changing and the price range also depends on design and style. That is why you can find the price of a heater ranging from 25$ to more than 2,000$. Before making your choice, try to understand what might be the cost of operating a certain space heater. Costs will depend on the type of heater and the room size. Large rooms such as basements will cost more to heat. 

This equation might help you out:

Kilowatts Per Hour x Electricity Rate x Operating Time = Daily Operational Cost

To determine the kilowatts per hour, see what is the on the heater and divide it by 1,000 (a 1,500-watt heater will use 1.5 kilowatts per hour). The cost per kilowatt hour is listed on your electric bill. Then you just have to know how many hours a day you´ll be using the heater. Here’s an example: 1.5 Kilowatts Used Per Hour X $0.10 kWh X 12 hours = $1.80 a day. Approximately $54 a month.

Other differences the consumers might find interesting between efficient energy space heaters and normal space heaters concern safety and noise. The most efficient ones have a multitude of features that will prevent them from overheating and wasting energy.

What Makes a Good Energy Efficient Space Heater?

Getting the grips with specifications of energy efficient space heaters will educate on how to make the ideal choice. When buying an energy efficient space heater consumers should look for features that save energy, money, improve safety and that are aesthetically appealing. One of the most important features is the thermostat and you can find heaters with programmable or adjustable ones. A programmable thermostat lets you regulate the room temperature and cycles the heater on and off to maintain the warmth. Adjustable thermostats don´t maintain the temperature, but still adjust heat based on your options.

On the other hand, programmable timers are also one of the most interesting features of energy efficient space heaters. You can set a heater to turn on and off at specific times and that you´ll save you a lot of energy. Multiple heat settings and energy saving modes are therefore common features in energy efficient heaters, as well as automatic oscillation that lets you distribute heat evenly through space.

For some, transportable energy efficient space heaters are a plus because some homes use space heaters as their main source of heat. For those who have pets or children, a cool to touch heater is a plus in what relates to safety. Some modern energy efficient space heaters have switches that turn off whenever the heater falls or overheats.

Indeed, all high quality models are silent and have an appealing design, besides having a multitude of heat settings that make energy efficient space heaters a convenient appliance for those who want to save money, energy and heat a space properly not forgetting aesthetics.

You will find portable floor heaters, wall heaters, space heaters and baseboard heaters. Floor heaters are compact and have a space-saving design, wall heaters are installed on interior walls and provide an extra source of heat, space heaters are suitable for tight places and baseboard heaters keep the environment warm from the floor to the ceiling. When buying an energy efficient space heater also keep in mind that there is convection heating, radiant heating and micathermic heating.

Convection heating is used in small spaces and is a good technology if you have pets or kids because ceramic space heaters have a cool to touch mode as the heating discs are hidden inside. Radiant heating delivers heat to areas directly in front of the heater like infrared heaters. Micathermic heating combines silence and efficiency and the process of convection allows the heat to flow in the room, heating the space evenly. It is also good for those who suffer from allergies or asthma.

For buyers, the most important is to heat a room evenly, to save energy and to feel safe at the same time, so look for features that can assure that.

How to Choose the Right Energy Efficient Space Heater

If you have a small space, choose a heater that is sized appropriately. An energy efficient space heater that has the right size for the space, produces the amount of heat needed to adequately warm the square footage of the room. As convection heaters use fans to create circulation of air in the room, they are good at keeping the heat distributed evenly throughout it.

They are also used for larger spaces because of fans, so you can also opt for a radiant heater as it radiates heat passively keeping a small space warm and cozy. If you have any respiratory issue, use a convection based one. You will also find energy efficient space heaters that combine radiate and convection heat, which is great to make the air flow, to keep the warmth and to heat small or larger spaces.

When choosing the right energy efficient space heater make sure you calculate power consumption and costs. Determine what technology is more suitable for you, radiation, convection or micathermic and choose your power source whether it is electricity or one of the petroleum oils.

The most important feature is the thermostat to regulate heat and save energy, but if the energy efficient space heater you choose also comes with a programmable timer, a cool to touch feature and a switch off system that prevents accidents after falling or overheating, then you have what you need.
