Winters haven’t subsided yet and heaters have remained in high demand as citizens flock to the nearest hardware store to get a space heater for heating their homes. Different types of heaters are introduced in the market for various purposes. There are small fan heaters to big large boilers for central heating systems but we’re going to look at what types of heaters are the best space heater for large rooms.

Types of heaters

The three main types of heaters are radiator, convection, and hybrid heaters that are a combination of both radiator heaters and convection. Radiator heaters are known to radiate heat outwards and are run on some sort of fuel (Gas, oil) or electricity. On the other hand, convection heaters use air circulation to heat an area. Then there are ceramic heaters that are considered to be hybrid as it uses ceramic for heat generation and fan to blow heat outwards.

It’s not just the type of heater that plays a role in how fast a room is heated. Baseboard, freestanding, wall, and more are some of the designs of a heater. A wall heater might be able to spread heat faster, unlike a freestanding one. Before we go to look at the best space heater for large rooms, let’s first look at the factors that one should consider before buying the best space heater for large rooms.

Factors to keep in mind before purchasing a heater

Here are a few factors that one must consider when buying the best space heater for large rooms.


You’ll never be able to heat the whole room if you don’t know about power and room size. Here’s a rule of thumb. For every square foot of living space, you need to have 10 watts of the heater to heat it. Start by measuring up your room and multiply it by 10. Use this as a rule of thumb to help you narrow down your heater choices.


There are different types of energy sources heaters use like gas, fuel, electricity and a combination of these. Cheapest among these energy sources are gas heaters as they can quickly heat the room but are considered to be dangerous among others. Electric heaters have a lower installation cost but are expensive when it comes to electricity consumption. Think carefully about what heater might suit your needs.


Look at your room where you want the space heater. See where the heater would look nice. Would it work well if it was sitting on the floor or wall a fireplace light up the living space better or a wall fit heater suits the aesthetics of the room? Many more questions may arise in terms of space, hence we do suggest taking your time in determining what would be best for space. Maybe you might find a standing heater more feasible since it can be taken from one room to the other.


This is a deciding factor for many as people want the best bang for their buck. Many prefer to have all sorts of features that they won’t even use when it comes to deciding what heater to purchase. However, not all features are worth considering. Take your time to understand which feature would work best for you (from the adjustable thermostat to timer and more) before purchasing a space heater.

Consider safety aspect before purchasing the best space heater for large rooms

Safety should always be everyone’s number one priority. You need to know that if you’re considering the best space heater for large rooms then you need to be wary of the safety standards. The space heater must go through rigorous testing before it is sold to the retailers. The best way to know if a space heater has been tested for safety is to look at some of the stickers.

Stickers like Underwriters Laboratory, Intertek, or Canadian Standards Association state that your space heater has been tested properly before being marketed. You might be able to see safety labels on the heaters box or the bottom or backside of display units. This can help you narrow down your search to find not only the best space heater for large rooms but also the safest.

Once you’ve identified that the space heater has been tested at the laboratory, it’s time to check the safety features of the space heater. Many like to go for a cool-touch exterior which ensures that the exterior of the heater does not heat up and lead to fire hazards. There are other safety features like the automatic switch-off function which turns the heater off when the space heater starts to overheat. There are also safety features like anti-trip which ensures that the heater switches off immediately upon tripping. This prevents carpets or other types of flooring from damage and fire.

There are safety features in gas heaters in regards to carbon monoxide switch off. If there is not enough oxygen for combustion, the heater will automatically switch off which interns prevent the production of carbon monoxide. If you’re in the mood for a gas heater for the winters, try to get vented combustion heaters as they are much safer than the unvented ones.

So, we’ve finally made it to the best space heater for large rooms section. The heaters will be categorized for individuals to make a sound choice.

How to use space heaters safely?

Firstly before using the heater, make sure there are all safety stickers and labels present on it. Once that is ensured, follow our guidelines below for safely using your space heater.

  1. Make sure the heater is placed on a hard flat surface that is prone to fire
  2. Keep a safe zone of 3 feet around the heater where all kids and pets will not be allowed. Not all heaters have a cool-touch exterior hence can be dangerous for those around.
  3. Remove any furniture or cloth materials like curtains, beddings, carpet, and more to avoid any fire breakouts. Many times there have been incidents over the news on a fire gone wild because of a space heater.
  4. Check the cord of the heater to see if there is any type of damage. Damages to the cord can lead to electrical faults and failures which can be hazardous to those that come in contact with it.
  5. Avoid plugging another cord in the same socket where the heater is connected. Heaters draw on a lot of power and having other devices connected can cause overheating.
  6. Make sure you have smoke alarms in the rooms where heaters are being operated. This is to ensure future safety in case if things go south.
