Buying Guide for the Best Large Draft Room Space Heater

Buying a good space heater for large rooms can be a rather complicated affair. Continue reading this in-depth buyers guide for the features that you should look for when buying a space heater.

Type of Heating

The space heater that you choose to buy may use one of these three heating methods to heat up your room.

Convection Heater

With a convection space heater, a heating element is used to warm the room up. The heating element warms the cool air that is sucked in when the warm air rises. The idea with a convection heater is to create a flow of air so that the warm air begins to heat the room.

You will find that these convection heaters function very well in confined spaces. If you choose to buy a convection heater, you will see that it comes with a built-in thermostat so that it regulates the temperature.

If you opt for a convection heater, you will see that it easily warms up the whole room well. However, it will heat the room up much slower when compared to a radiant heater. Hence, it is an excellent option for rooms that are large but not as much for those with high ceiling.

This is because the convection causes the hot air to float to the ceiling and the colder air remains down. This will continue until all of the air is slowly warmed up to an appropriate temperature.

Radiant Heater

These heaters utilize infrared radiation that does not heat the air surrounding the heater. Instead, these waves reach the target object and heat it up. You may have experienced radiant heating before if you’ve ever sat before a campfire.

Do note that radiant heating does not need any medium. Hence, it gets the room heated rather quickly. However, it will be difficult to heat up an entire room using radiant heating due to its concentrated heating. They are, however, a great option for heating still air and zones.

They are also a great option for rooms with high ceilings. By placing the heater well and seeing to it that nothing obstructs the infrared light, you will be able to heat the space up very well.

Combination Heater

For large rooms with high ceilings, a good space heater is one that combines radiation and convection for widely spread out and low heating. Micathermic heaters are great combination heating options.

These heaters have mica, an element that produces electromagnetic waves. These waves heat up not just the air near the target object but also the air that it comes in contact with. Hence, it spreads the warmth both in the room and near the ceilings.

With this, you can expect a warm and toasty room during the cold winter nights.

Room Size (Large or Small)

If you want to heat a larger room, you need the right power on the heater to match this. If you have 1 sq. ft. of space, it will take 10 Watts for efficient and warm heating. By this standard, you can opt for a heater of 1500 Watts for a room that is sized at 150 square feet.

The best idea is to have a rough idea of the largest room in the house that you want to heat. A 1500 Watts heater should work very well for a ceiling of 8 feet in height. If the height is above 8 ft., this standard rule may not be applicable.

For every 2 feet above the 8 feet mark for the ceiling, you will have to opt for a space heater with an extra 25% wattage.

Room Insulation

If you have a well-insulated room, you can pick a heater by only thinking about the size of your room. However, you will have to take insulation into account if you have any vents that allow cool air into the room.

In this case, look for an extra 20% wattage to account for poor insulation. Many people opt for two space heaters for optimal heating in a room.

Features to Look for in a Space Heater

A good space heater for a large room with high ceilings should have a few features that make it an appropriate purchase. Read ahead as we list out those features that you should look for in a space heater.


Safety is a feature in a space heater that should be a priority as you make your purchase. It is very easy to get burns from a heater that does not make safety a key feature. If you are using a heater in a large room, you will have to leave it on for longer durations.

Inevitably, the body of the space heater will heat up and reach a temperature that is enough to cause a burn injury if touched. Hence, many of these heaters overheat and are a potential safety hazard.

When buying a heater, look for one that looks into this aspect. Today, heaters have come a long way, and you will be able to find ones that have a cool exterior even when heated. Others will have heatproof handles that will let you touch and carry them around even when heated.

You may also want to look for heaters that are fireproof. These have been designed such that they dissipate any heat efficiently and quickly. You may also ensure that the heating elements in a space heater are not exposed.

A good idea is to look for heaters that automatically turn off when they detect any overheating. This is an important feature, and most space heaters should have this option. This is especially necessary if you have children as well as pets at home as they are likely to accidentally injure themselves from a hot space heater body.


A portable space heater is also one that is compact. This will help you store it away easily when not in use. A compact space heater is also often a lightweight one. Hence, it is easy to move it around from room to room.

A portable space heater also tends to save up on the amount of energy used as you may not be using central heating. Hence, you may want to move it from room to room as you move. Perhaps, you may want to first heat your children’s rooms and later your own.

To do all of this, it is a good idea to look for a heater that has wheels below it. With this, you will be able to drag it around from room to room easily. A convection heater need not be as portable as it can heat the air in the entire room from its standing space.

An infrared heater, however, works differently and will need to be moved around so that it can heat the right target in the room. If you are opting for an infrared heater, make sure that it has wheels attached to make moving it around easier for you.

Without this portable feature, it can take a lot of effort and pushing to move the space heater around.


High ceilings and a large room are present in spaces where guests are likely to visit your home. You may also have your family game nights and other activities planned in this space. A noisy space heater can distract and take the joy away from these occasions.

To avoid this, look for a heater that has a low noise level. Fans often contribute quite a lot to the noise that your heater will make. A good idea is to look for a space heater that comes without a fan.

Look for a space heater that operates at below 32 decibels and close to 25 decibels and below if possible. These heaters keep quiet and will ensure that you can have all your gatherings or solo reading sessions in peaceful, quiet, and cozy heat.

Frequently Asked Questions (FAQs)

Here are some of the commonly asked questions about space heaters answered for you.

What is the best way to heat a large room quickly?

Any portable heater can do this for you. If you want to look for a space heater option that can quickly heat a large room, look for a combination space heater. These combine the best bits of convection and radiation to heat the air in a large room quickly.

Why is it difficult to heat rooms with high ceilings?

High ceilings keep a room spacious and ventilated. However, they also allow the warm air given out by a heater to float up to the ceiling leaving the lower portion cool. Hence, it takes much longer and more energy to be able to heat a room with a high ceiling.

How to make a high ceiling room feel warm and cozy?

A ceiling fan is a solid option to heat a room with a high ceiling. In the winters, these fans can run in reverse so that the warm air is pushed down. When combined with a space heater, this can keep the room feeling cozy and warm during the colder months.

Why are ceilings usually 8 Ft. tall?

Heating and cooling can take some effort and lots of energy. In the 1970s and 1980s, an energy crisis gripped the USA, and ceilings were brought down to 8 ft. so that energy required to cool and heat living spaces can be reduced.

This convention for timber houses stands true to date.
