The Dr Infrared Portable Space Heater is our top pick as the most reliable and energy-efficient space heater on the market.
It uses infrared technology to heat your rooms, meaning it can sense spots in your rooms that need heat and distributes it accordingly. The Dr Infrared heats objects in your room instead of filling out space with heat.
This means warm air won’t rise to the ceiling and disappear and remains constant without being intruded on by drafts. It can also retain moisture in the air, meaning your skin won’t dry out from using the Dr Infrared.
Best of all, it doesn’t have any exposed heating elements. This makes the Dr Infrared much safer to have around pets and small children.
While it’s not the cheapest option out there, the Dr Infrared is quiet, energy-efficient, and contributes to better home comfort.
If you don’t want a chunky space heater taking up floor space, wall-mounted heaters are the way to go. And when it comes to wall-mounted heaters, the Stiebel Eltron CK 15E is one of the most reliable options out there.

If you’re looking for energy-efficient space heaters, we recommend you first air seal and insulate your home.
Because air sealing and insulation can have a big impact on your energy consumption. They also help your home retain heat so that you can maximize the benefits of your space heaters during the winter.
Buying a space heater with poor air sealing and insulation is like putting a band-aid on a big, open wound. It’s not going to completely stop the bleeding. And it’ll likely do more harm than good down the road.
Air Seal Your Home
Air sealing is all about filling or covering air leakages in your home. While they may seem arbitrary, they actually account for anywhere between 25% to 40% of the energy lost when cooling or heating your home.
Think of it like a boat floating in the ocean. The smaller holes you have, the more water you’ll have in the hull. This causes your boat to sink and make it a bad day for everyone.
It’s a similar concept with air leaks. The smaller holes you leave unplugged, the more cold air you’re letting in. Your space heater and HVAC system can do everything it can, but your home will still be cold.
Air sealing is usually done with caulk, insulation, and spray foam depending on the size of your air leaks. Common places to air seal are your windows, attic hatches, attic floor holes, fireplaces, and even electrical outlets.
You can check for air leaks by placing a candle or incense next to a potential area and seeing if the smoke or flame moves.
Another way of maximizing your home’s energy efficiency and improving comfort before adding space heaters is insulation. Insulation helps maintain your home temperature by keeping warm or cold air inside your home.
The laws of physics dictate that heat travels upward, in this case towards your upstairs rooms and your attic. This means warm air produced by your heaters and HVAC system travels to your attic and escapes through your roof or other holes.

Insulation can be installed in the attic or your walls to keep that heat from escaping. This translates to greater energy efficiency, as the EPA states that insulating attic floors, walls, and ceilings help homeowners save up to 15% on their annual energy bills.
Insulation comes in different materials. The most common types of insulation are fiberglass or cellulose, which either come shaped like mats or can be broken up into smaller pieces. There’s also reflective insulation which can be placed in attics to reflect heat back into or out of homes.
When to Use a Space Heater
If you’ve air-sealed your home and added insulation to your attic, floors, and walls but want even more warmth and comfort in the winter, then space heaters are definitely the way to go.
But why space heaters? Doesn’t your HVAC system give you enough warmth already?
Many homeowners choose space heaters because it lets them localize the heat more. Instead of heating their entire house, some people might only want to heat the rooms they more frequently occupy.
Using a space heater also simplifies the home heating process. While there are plenty of benefits to a comprehensive HVAC system, there’s nothing like plugging in a heater and flipping on a few buttons to enjoy the warmth.
Space heaters shouldn’t be used as replacements for an HVAC system, but they can be convenient solutions for particularly cold days.
Do Space Heaters Use a Lot of Electricity?
Space heaters are a popular way to stay warm during the colder months. However, there is some debate about how much electricity they use.
Some estimates suggest that space heaters can use as much as 1500 watts of power, which is more than most other appliances in the home. Others claim that newer, more efficient models use less than 1000 watts.
Regardless of which estimate is more accurate, it’s clear that most space heaters do use a significant amount of electricity. As such, it’s important to be mindful of how often you’re using your space heater. It’s also helpful to address your home as a whole and to make sure it is properly air sealed and insulated. By taking these precautions, you can help to keep your energy bills down during the winter.
Space heaters are a nice way to add additional comfort to an already energy efficient home. Use this article to find the perfect heater to fit your budget and style preferences.
