What is a space heater?
Space heaters are devices that offer supplemental heating to a small- to medium-size space. These devices are usually electric or powered with a fuel, like gas or oil. Space heaters come in many shapes and sizes and can help keep your energy costs low.
Deciding which space heater to choose can be a tough decision, so we’ve done the research for you.
Types of energy-efficient space heaters
Before deciding which kind of space heater is best for you, it’s important to consider the different types of heaters on the market. Each heater is designed to offer maximum warmth with minimal energy wasted. Read on to find your best heater.
Gas and oil-filled heater
Oil-filled heaters are a very popular option and most models look similar to old-school radiators. They have a set of columns that house the oil used for heating. Since the oil isn’t used as a form of fuel, you won’t ever need to replace or refill it.
Oil-filled heaters work by converting energy to heat through the use of the oil inside. The heat is absorbed by the oil as it circulates through the columns and fins. Heat is then transferred from the oil to the metal fins of the heater where the heat begins to radiate throughout the room.
One of the cons of gas and oil-filled heaters is that it can take 20 to 30 minutes to feel the heat being produced. However, once the oil is warm, the unit is able to maintain heat for a long period of time. Many gas and oil-filled heater models have adjustable thermostats, programmable timers, and heat silently to allow for an easy heating experience.
Electric infrared heater
Electric infrared heaters are highly energy-efficient and work by converting electricity to radiant heat to warm the surrounding objects in the room. Electric infrared heaters warm spaces by converting energy to radiant heat.
Similar to how the sun warms us when we’re outdoors, radiant heat warms people and objects in a room, not the air in between. Since none of the warmth is wasted on heating empty space, an electric infrared heater is one of the most energy-efficient models.

As the name suggests, ceramic heaters utilize a heating element made of ceramic. That component heats the air that is pulled into the heater and the warmer air is redistributed throughout the room.
Ceramic heaters are typically encased in plastic and are very lightweight and portable. There are two types of ceramic heaters: those that operate with a fan and those without a fan.
Convective ceramic heaters
Convective ceramic heaters use a fan to distribute warm air into a room. The heaters are powered with electricity that heats aluminum parts within the unit that then transfer heat to the ceramic heating element. The unit takes cool air from the base of the heater and pushes it over the heating element. The air is warmed and redistributed throughout the space by a fan inside the heater.
Radiant ceramic heaters
Radiant ceramic heaters use energy to heat the ceramic plate and then radiate heat directly to objects in the room. This kind of ceramic heater does not use a fan. While radiant ceramic heaters won’t heat up a room as fast as a convective ceramic heater, these units do provide more long-lasting heat.
Convection heaters work by pulling cool air into the device to be warmed by the heating element. The heated air rises while the cold air stays closer to the ground where the heater can pull in the cool air and begin the process again. This continued cycle of air allows the heater to produce a constant flow of warmth. These heaters come in a variety of shapes and sizes and can be wall-mounted or portable. Most units are relatively quiet and evenly distribute heated air throughout the space.
