Buying Guide for Large Room Heater

There is no better way of raising warmth in rooms than purchasing a heater. However, it’s not easy to select the perfect unit for your needs. Here are the things you need to focus on when choosing a suitable heater:

Heater Type

Depending on the technology they use, you can choose from:

Convection heaters are ideal if you want to add warmth to a single room. They are efficient, and they can keep the area warm for long.  Convection heaters deliver even heat by circulating air across whole rooms. The recommendation is to buy one of these units if people spend a lot of time in the room you want to heat.

Radiant heaters work differently than their convection counterparts. Instead of focusing on the entire space, the warmth they provide is best felt in front of the unit. As a result, that specific area can be warmed up quickly Infrared heaters offer similar results. However, that does not make them ideal for large rooms.

Micathermic heaters are a combination of the two. They have a panel that radiates the heat, and the air then circulates across the heating space. Micathermic units don’t use a fan, and they work silently. The fact that they are without a fan also means that they don’t recirculate allergens or dust. 

Heater Design

Here we have four types to consider:

  • Wall heaters
  • Floor heaters
  • Personal heaters
  • Baseboard heaters

Wall heaters, as the word suggests, are mounted on walls. Various models are offered, such as electric fan heaters, fireplaces, and panel units. They are ideal for delivering supplemental heat in cold spots. 

Floor heaters, in most cases, have a vertical design and a small footprint that saves space. They are portable and usually use fans to heat the room.

Personal heaters focus on the area in front of them. They are ideal if you want to keep yourself warm or deliver warmth to a small portion of space instantly.

Baseboard heaters deliver constant heat, and they are silent. They start from the floor and heat the air up to the ceiling. People often put them in basements as they can offset drafts, especially if you install them under windows.

Safety 

Before moving to other features, you should consider safety. Companies that design heaters should have keeping their users safe as a top priority. Look for evidence that the components have been tested for faults and hazards and security certificates issued by authorities. Favorite safety features include overheat and tip-over protection switches.

Other features

Here are several other features that you want to keep in mind when choosing a large room heater:

  • Noise level – the units that have fans will produce more noise than those without one. However, newer heaters with fans can also be silent
  • Multiple heat settings – these will allow you to choose the warmth level you want for the room
  • Remote control – you’d want to be able to control the unit from a far
  • long-arrow-right
    Energy saving – some units also offer modes where the usage of energy can be decreased, which also lowers the cost

How Many BTU Do You Need for 1500 Square Feet?

When purchasing a heater, the crucial thing to make sure is that it has the power to warm the planned space. There are two ways to check that – wattage and BTU output. Wattage is the heating power a unit can deliver. The general rule is that you need 10 watts per square foot. 

However, most people focus on BTUs when calculating the heat output. The reason why this is the case is that BTU rating measures heating capacity instead of power.

A BTU is an abbreviation for British Thermal Unit. You can calculate it by multiplying the wattage power of the heater with 3.41. So, every watt of power will equal 3.41BTUs regarding heat output.

If we do the math, we can see that approximately 51,150 BTUs of heat is needed to heat 1500 square feet. This might mean that you will need to purchase several heaters to heat that large room properly. 

When you are using space heaters for large spaces, you also want to know how much it will cost you. That is why I want to reveal a simple equation that you can use to calculate the daily operational cost.

To determine the price, you need to multiply operating time with electricity rate and kilowatts per hour. To find out the last one, check out the wattage output and divide it by 1,000. For example, an average 800-watt heater will use 0.8 KW per hour.

What Size of Heater Do You Need? How It Measures?

The size of the heater that you need is proportionate to the size of the room you plan to heat. If you think about it, that sounds perfectly logical. In the end, it all comes down to whether the heater will be capable of delivering the results you expect from it.

That is why the BTU power should be your primary consideration. In general, the experts recommend that a minimum used for calculation should be 30 BTUs per square foot. However, there are several factors you need to consider that may increase this number.

Climate

The very first thing you want to consider is climate. If you are living in cold areas, there is a good chance that you will need extra BTUs to heat the room properly.

The general rule is that you should take a look at your geographical location and its position compared to the equator. The further away you are from it, the more BTUs you will need. If you are living in the United States, you can take a look at the recommended BTU amounts on this website.

Insulation and State of the Room

The next thing you want to consider is the age of the house or the room you are planning to heat. The general rule is that newer spaces will have better insulation than those built decades ago. That is because the building codes have changed for the better.

If you believe that the area you are heating is well insulated, there is no need for extra power. On the other hand, if it’s an old room prone to drafts, take a look at the heating zone chart and use the upper BTU limit.

Here are a couple of pointers that can help you:

  • The number of windows will increase the possibility of drafts
  • Low ceilings mean that space can heat up quickly. High ceilings require extra warmth
  • If a lot of people is in the room, it will take less time to get it warm

Measure the Total BTUs Needed

At this point, you’ve decided how many BTUs you need per hour to properly warm up that large room. Now, all you need to do is to calculate the total BTU amount required.

To do this, multiply that number by the square footage. For example, if you want 35 BTUs of heat per square foot and you have 1,000 square feet of space you will need 35,000 BTUs of power in total.

Final Thought

It seems that we have reached the end of the article about the best space heater for large room. I am glad that I’ve got the chance to share my knowledge. I hope that you enjoyed reading the review and that you found out useful information from it.

The crucial thing to keep in mind is the size of the room you want to warm. Your primary concern should be to choose the space heater based on that information.
