Buying Guide

Factors to Consider When Deciding to Purchase the Best Space Heater for Large Rooms

  • Physical Size

    If you want to know which size of heater is best for you, the first and most important consideration is power. If you're going to heat a whole room, you need to measure its size. In general, 10 watts will heat 1 square foot of space, so you will need to find a heater that can heat the size of space you are considering. There’s a vast range of space heater sizes available. Depending on the dimensions of the room or area you’re planning to use it in, a smaller heater could be the smart choice.

  • Ease of Setup

    Electric heaters generally come ready to use out of the package (or at least require minimum effort to set up), but gas heaters often demand the purchase of additional fixtures to make them work.

  • Ability to be Mounted

    Some heaters come with fixtures that let you mount them on the wall or ceiling, something that can be highly useful in small spaces.

  • Temperature Controls

    A wide spectrum of control levels can be found in different space heaters. Determine whether you want low and high comfort settings or are interested in more specific degree levels.

  • Thermostat

    Some heaters include a built-in thermostat that will keep track of the temperature in the room and adjust its output levels accordingly.

  • Safety Features

    Safety features like an automatic shut-off if the machine gets tipped over or overheating prevention are essential for stress-free use.

  • Heat Level of Casing

    Sometimes the outer casing of a heater can get very hot to the touch while it is in use. If you have pets or small children, it is important to know which models this is a problem with before making a purchase.

  • Timer

    If you often forget to turn off appliances when you’re done, find a heater with a built-in timer that will turn the machine off for you in case you forget.

  • Noise Level

    If you are sensitive to noise, try to find a heater that doesn’t have a fan. Radiative heaters often run this way and are much quieter for it.

  • Remote Control

    Some models include a remote control that allows you to adjust temperature settings from across the room. On a chilly night, this can be especially convenient.

  • Aesthetics

    There is a wide range of choice available in the shape and color of space heaters. Propane burning devices are generally less attractive than their electric cousins. Tower shaped heaters are popular, and you’ll also find some that look like fireplaces or old-fashioned radiators.

  • Fuel options

    If you have small children, you may find a propane tank heater a little dangerous. Equally, if you do not have gas lines installed in your house, a gas heater may be out of the question due to the high installation costs and disturbance. Electric heaters tend to be cheaper up front. Although, gas heaters tend to be cheaper to run than electricity and could be a better option if they fit your criteria.

  • Location of the space heater

    Think about the space you have to put a heater. It's important to give the space heater plenty of room and to ensure that there are no flammable items nearby. This includes bedding, curtains, clothing, and similar items. The radius around the space heater should be clear of all things, and children and animals should be watched very closely around space heaters.

  • Portability

    Alternatively, you may be looking to have a surface wall heater that you can tilt for workshops and garages. Perhaps a free-standing heater is more suitable for portability so you can move it from room to room. Understanding the design will help you narrow down your choices.


Q1. What Area Do You Need To Heat?

When you are considering which heater to use, you should always consider the size of the space that you will need the space heater to warm up. If you have a larger room, for example, you will probably benefit more from a fan forced heater. You can find larger industrial sized heaters that can provide heat quickly to the room and maintain the circulation to keep the larger room warm. On the other hand, if you live alone, you will be able to save money on your heating bill by choosing an infrared heater.

Q2. How Much Power Do You Need?

The amount of power that you will need may vary from room to room if you are going to be using the heater throughout your home. If you simply want to heat a single room and use a more permanent space heater, you will be able to accurately work out how much power you need to heat the room.

On the other hand, if you want to take the heater from room to room, you should look out for the heaters that have variable power options so that you can conserve energy when you don’t need the heater to be so powerful.

Q3. How much should you spend on a space heater?

Cost doesn’t need to be a problem when you are looking for a space heater, as there are all kinds of space heaters available to suit many budgets. Whether you want something basic, or a more feature-filled heater, you are bound to find something that will suit your needs.

You should remember that the initial cost of purchasing the space heater would not be the only cost that you’ll have to consider. Think about the cost of running it. Electricity can be expensive, mainly if it is used wastefully by using a heater that is too powerful, or a heater that needs to be on the whole time without actually ever heating the room as it is insufficient.


Well, buying a space heater for a large room is not a difficult task once you have a clear idea about the features of the product. There are numerous brands of heaters that offer a variety of functions according to customers’ demand. All you need is the information about your home and what you need – and you will find the heater suitable for you in no time. We hope that the above review will be of great help as you head to the market, to buy yourself one of the best space heater for large room and say goodbye to cold weather.
