What is a Commercial Heating System?
Today, a variety of commercial building heaters work hard to provide businesses and building owners with reliable access to the heat necessary for comfort and daily operations, no matter how large or small the space. Just as there is great variety in the types of areas which require heating, so too is there a diversity of choice when it comes to the systems responsible for providing heat to those areas.
While many installations may function similarly to how a central heating system works in a house, others are different, and all of them operate on a much larger scale than a residential unit. Though many business owners may know the basics of the heating systems upon which they rely, a more in-depth and functional knowledge of their operation can prove elusive. As a result, there may be room for improvement in operational efficiency and functionality that you’ve missed. To help equip you with all the facts necessary for a basic understanding of this vital infrastructure, consult this helpful guide for commercial HVAC heating systems.
1. History of Indoor Heating
It’s easy to take for granted the numerous and complex systems we have for staying warm indoors today, but behind that reality is decades – even centuries – of hard work and innovation. Pinpointing when the first heater was invented is difficult owing to the many forms heating has taken over the years. However, the most common example is the Roman hypocaust, which used hot smoke from a contained fire to warm floorboards and walls. Ever since then, people have sought more effective ways to heat indoor spaces consistently.
Though Adequate for Smaller Spaces, Convective Heating is Very Inefficient Overall
While other ancient societies experimented with the development of installations that seem similar to the idea of a central heating system, including India and later Romans, simple convection was the primary means of moving warm air into cold spaces. Though adequate for smaller spaces, convective heating is very inefficient overall. It takes a leap forward in time to the Industrial Revolution before we begin seeing the advent of ideas that would lead to modern installations, such as the development of hot water radiator heating systems.
While a 1950s furnace looks and functions remarkably differently from modern central heating systems, the principle remains the same: create heat in a central location and force it into spaces requiring warmth, whether by forced air, a hot water heating system, or another form of commercial heating supply. Today, “smart” technologies help improve functionality and efficiency even more, from learning when heat will be necessary to computer-controlled combustion and airflow.

2. Types of Commercial Heating Systems
Though the history of the commercial heating system is long, much of its development has taken place over the last 50 years, with many innovations and new designs intended to function at very large scales. Let’s quickly break down the different types of heaters and look at the advantages – and disadvantages – each choice brings along with them.
The most common type form of commercial heating. Often fired by natural gas, burning fuel heats a large volume of water which is then pumped throughout the building to radiators, baseboard heaters, and other specialized panels for heat distribution.
Warm Air Heating
The second most common form of commercial heating is the typical central “forced air” system found in many homes scaled up to meet more demanding needs. Fuel in the combustion chamber (or electric resistance coils) warms a heat exchanger which in turn heats the air. Powerful fans then blow the heated air throughout ducting.
This system relies on hidden tubes of flexible plastic. Most commonly placed in special paneling or under-floor tiles, radiant heating may use electric coils to send heat up into the space, or a liquid. This liquid may be water or another liquid medium chosen for its heat capacity. Water sent from a central heater flows through the tubing and warms the space.
Natural (Geothermal) Energy Heating
Less common but growing in popularity thanks to an increased emphasis on green technologies, geothermal heating uses deeply buried liquid-bearing loops to soak up heat trapped deep underground. The system brings this warmth up using a heat pump, which powers radiant systems or similar technologies.
Electric vs. Gas
When considering warm air furnaces, one of the big debates you’ll encounter is whether to opt for an electric-only heater or one powered by gas. Which is better? The answer may be “it depends,” but that is also the truth.
3. Efficient Heating Systems
While the type of commercial heater you choose will have a significant bearing on climate control outcomes, the equipment itself is ultimately a means for achieving the implementation of the most efficient heating system possible for a building. Understanding how to work towards achieving that goal starts by first understanding what efficiency means in this context.
1. What is Heater Efficiency?
In this context, efficiency is merely a measure of how much of the heater’s fuel source it can convert into energy for warming.
2. How is Efficiency Measured?
For furnaces, the best way to understand efficiency is to use a measurement such as “annual fuel utilization efficiency,” or AFUE.
3. Design Elements Impacting Efficiency
Many different parts of modern furnaces impact efficiency. Some you’ll find standard on most units, while others may be worth seeking out with the help of your HVAC professional.
4. How to Maximize Efficiency

5. Overall Cost
The cost of operating a heater depends heavily on its efficiency, and thus can be quite variable, but it is still only one element to a heating system’s price.
6. Life Cycle Analysis
When choosing a new heating system for a commercial application, requesting a lifecycle analysis from your HVAC services provider may be a good idea.
4. The Most Common Commercial Heating System
With efficiency and central heating systems explained, the next natural curiosity to arise often concerns what heating option you should choose. What do most commercial operators select for their buildings? Of the many types described above, boilers are most commonly found throughout large to medium-sized buildings. However, forced air systems powered by gas furnaces continue to grow in popularity and package units of all types, including central heating using electric power, can prove a viable option.
Commercial boilers may be small and simple or large and complex, but they are all functionally the same in operation. Using either traditional fuel such as natural gas or the power of electricity, a large volume of water undergoes heating to a high level – often as high as 180 degrees or more. Circulating this hot water through metal radiators placed throughout the building allows rooms to warm as needed. As mentioned above, water retains heat for a long time and thus provides more consistent and cost-effective heat. However, boilers also do not require the movement of air, and therefore, can contribute to better air quality in large buildings. The can also eliminate costly maintenance such as duct cleaning.
By far one of the most significant advantages for modern boilers is their high efficiency. While the boilers of yesteryear were quite inefficient, sometimes reaching an efficiency of barely 50%, today’s high-end units can achieve efficiency between 90 and 98.5%. In other words, nearly all the fuel or electricity your business purchases for heating actually goes to that end. While gas furnaces can sometimes achieve similarly high levels of efficiency, boilers get there consistently – and that explains why they remain so popular.
5. Heating System Placement
Choosing a commercial heating system is only one aspect of the process of tapping into the benefits it will bring to your business. Understanding the considerations for where to put the system matters, too. Here’s a quick look at what owners must think about when considering the placement of a new heater.
Heating System Placement
What to Consider
Boilers are typically quiet, but gas furnaces are known for their wide variety of sounds. In forced air systems and with heat pumps, the sound of the blower and extractor fans can prove a frustrating distraction.
When considering unit placement, think about ease of access for service professionals in the future. Don’t place a unit somewhere that would make maintenance difficult, it can prove costly and challenging to work on the unit.
Furnaces and boilers aren’t small; they need specific areas dedicated to their function. It’s especially true for furnaces which require a sufficient volume of air to draw upon for combustion. Carefully calculate space requirements and evaluate suitable spaces in the building with the help of your contractor.
Consider the potential effects on efficiency based on placement. For example, a boiler placed too far away from most of the radiators will not yield the best results. Likewise, a furnace put in a space that is too small will struggle to consume fuel fully, leading to unnecessary exhaust and inefficiency.
Yes, even the climate outdoors can affect your system and should be a consideration when placing a new unit. For example, package units which reside outdoors or on the roof of your building may be susceptible to snow or icing conditions during very cold conditions. Low temperatures can have a deleterious effect both on the equipment and its ability to operate.
6. Maintenance & Service
Your business may have a well-defined energy budget, but what portion of those funds have you earmarked for upkeep of vital systems such as your furnace or boiler? The efficiency of commercial heating systems, as we’ve explained, can depend heavily on good maintenance and proper operation. Here are the essential facts to understand.
1. Should I have the ductwork inspect my building?
2. Which thermostat is right for my commercial building?
3. How long should my commercial HVAC last?
4. Why are humidifers used more in heating than cooling?
5. How do I know if my heating unit is big enough?
6. How can I increase the efficiency of my HVAC system?
7. Why is commercial heating and cooling so maintenance so important?
