What Is the Best Way To Heat a Large Space?

Finding a proper heating solution is never easy, but it can be even more challenging if you’re looking to heat a larger space. An inadequate heating system can make some of your household’s main areas, such as the living room, uncomfortable in the winter, so it’s crucial to find a reliable option.

The best way to heat a large space is to install radiant heating under your floor. For those looking for a more budget-friendly alternative, using a space heater is the way to go. If you need to heat an industrial space such as a warehouse, you can install a warm air heating system.

In this article, I’ll take you through everything you need to know about heating a large space, regardless of whether you’re planning to use it for living or storage purposes. 

Heating Large Spaces

Large spaces can be tricky when it comes to heating. Not only do they require a larger amount of energy to be produced, but the heat created by this energy needs to be distributed equally throughout a bigger surface, which isn’t always easy to achieve.

So, what’s the best way to heat a large space? There are two possible options depending on whether you’re heating a living area or an industrial space: 

Best Way To Heat a Large Living Space

Properly heating your household should always be a priority. But finding the most efficient alternative can be challenging, especially if you have large rooms or an open design plan for your living space.

The ideal solution for heating a large living space is installing radiant heating underneath the flooring. This method is a relatively new trend in modern housing that focuses on comfortable, efficient, and design-friendly heating.

There are two types of radiant floor heating:

  • Water-based: warm water runs through the pipe system to create heat
  • Electric: electric wiring is used to create heat

Both of these alternatives provide heating from the floor up, allowing for proportionate and efficient warmth throughout the entire space they cover.

One major issue with this heating method is that it’s costly and difficult to install, especially if you have an older home. However, if you’re building a house from scratch, installing radiant heating might be a little more convenient.

Best Way To Heat a Warehouse

With increasing energy costs and tighter regulations, industrial heating for large spaces is becoming more difficult. However, the need for good heating and warmth in warehouses remains the same, as it’s essential for the workers’ comfort.

There are two main options for heating a warehouse:

Warm Air Heating

A warm air heating system increases the air temperature inside a space by drawing it into a heat exchanger. Afterward, the air is distributed throughout the area with a fan. Warm air heaters can be mounted on walls or suspended on the roof of the building. 

The energy source for the heater can be gas, hot water coming from a boiler, or electricity. The most efficient models are gas (otherwise known as direct-type) heaters, which now come in condensed versions and operate similarly to condensing boilers.

Radiant Heating

Radiant heating can be provided by installing suspended radiant tubes or by wall-mounting radiant plaque heaters, which is far less common.

This method doesn’t warm the air inside the building. Instead, it emits infrared radiation to warm up people and objects. The main disadvantage with this alternative is that people need to be in the radiators’ direct trajectory to feel the heat, which may prove to be difficult in a large, busy space such as a warehouse.

Alternative Heating Methods for Large Spaces

The previously mentioned methods may not be accessible or ideal solutions for everyone, so here are some alternative heating methods that can also provide sufficient heating to larger spaces:

Duct Booster Fans

While HVAC units are great at heating small to medium-sized rooms by pushing hot air out of the vents, these types of systems won’t be optimal for a large room or a living space with an open design. Heated air travels up, meaning it won’t be able to get to every part of an ample space before reaching the ceiling.

However, this doesn’t mean that an HVAC system would be utterly useless in large spaces. To boost its effectiveness and airflow, you can install a duct booster fan to the ductwork. Keep in mind that a duct booster will only work with HVAC systems that are already in good shape and only need a slight boost.

Space Heaters

There are some significant cons to just using space heaters to warm up a larger space. Firstly, it’s by far the least efficient and cost-effective heating method. 

On the other hand, space heaters have a few advantages that may still make them the ideal choice for some people. The most obvious one is their convenience. You can move them around the house fairly easily, and all you need to do for them to work is find where to plug them in.

While most space heaters are only designed to heat a smaller area effectively, there are many types of space heaters on the market, some of which could be ideal for a larger room.

When looking to buy a space heater for a large space, apart from power, you should also consider its airflow capabilities. Without proper airflow, the heater won’t distribute the hot air equally throughout the entire area. For this reason, I’d recommend taking a look at the Lasko Automatic Airflow Heater (available on Amazon.com).

This Lasko heater provides excellent heat distribution due to its efficient design. It’s both powerful and space-saving, making it ideal to use in a home setting without having to compromise aesthetics. Furthermore, it comes with an excellent tip-over safety switch that prevents it from overheating.

Tips To Heat Large Spaces Effectively

Regardless of the heating method you choose, there can always be some additional steps you can take to improve its power and efficiency. Here are some of the best tips to optimize the performance of your heating system:

Insulate the Space

Proper insulation will boost the efficiency of any temperature control system. The entire house should be insulated from the roof to the foundation for optimal results. Additionally, it’s also important to caulk all your windows and doors.

A fully insulated home will keep away the extreme cold during winter and the unbearable heat in the summer, keeping the temperature inside your home stable and less costly to manage.

Carpet the Floors

A nice carpet won’t only make the room look more aesthetically pleasing but will also help keep it warmer. Bare floors can let around 10% of heat escape through them, which may not sound like a lot but it’s more noticeable than you’d think, especially during wintertime.

By having a carpet or a few rugs across your large space, you’ll maximize the amount of heat produced by your heating system that your room is able to maintain

Install Thick Curtains

Since most homes are decorated using the same model of curtains throughout, homeowners often opt for lighter designs that are easy to install and adjust. However, lighter curtains aren’t ideal if you want to keep a room warm since they’ll allow heat to escape through the windows.

Therefore, you’d want to install thick curtains with thermal lining for the best results. I recommend NICETOWN Grommet Blackout Curtains (available on Amazon.com) as they’re easy to maintain and install while also being great for insulating your space from both heat and cold.

It’s also worth noting that curtains should be used wisely, as opening them from time to time allows sunshine to get into the room, which can provide some natural warmth to the space.

Heating a large space can be challenging. But if you’re able to deal with this issue during the construction of the house, it can easily be managed by installing radiant heating under the floors. For non-living spaces like warehouses, it’s best to install warm-air heating, which warms the air in the building and distributes it evenly through a fan.

Other heating options include duct booster fans and space heaters. To improve the efficiency of your heating system, make sure the space is adequately insulated. It would also help to install thick curtains and carpets.
