Everything You Need to Know About Heating A 40×60 Shop

heating a 40×60 shop


Is your 40×60 shop feeling chilly? It’s time to explore heating systems to keep your workspace warm and cozy.

So, what should you do for heating a 40×60 shop?

Firstly determine the required BTU according to your shop size, insulation, ventilation and desired temperature. Then choose a heating system according to your preference. The suitable heating options for a 40×60 shop are forced air, radiant and infrared heating systems.

In this article, we’ll discuss the factors to consider for heating a 40×60 shop. Also, take a look at the suitable heating options available and help you choose the one that’s perfect for your needs. 

Heating a 40×60 Shop

Heating a large shop like a 40×60 one can be a daunting task. You can choose the perfect heating system for your 40×60 shop by considering some important factors. 

Factors to Consider 

Now, let’s discuss some of the key factors you have to keep in mind when selecting a heating system. Heating Your Workshop

Required BTU 

One critical factor is determining the required BTU based on the shop’s size, insulation, ventilation, and desired temperature.

BTU Calculation

A 40×60 shop has a square footage of 2400 square feet. However, the standard ceiling height is 12 feet, so we can calculate the volume of the shop:

(40 x 60 x 12) feet = 28,800 cubic feet

Next, let’s consider the desired temperature of 68°F. We can then use the following formula to calculate the required BTU:

BTU = Volume (cubic feet) x Temperature Rise (°F) x 0.133

Where 0.133 is the specific heat of air.

Assuming a temperature rise of 30°F (from an outside temperature of 38°F to an indoor temperature of 68°F), we can calculate the required BTU:

BTU = 28,800 x 30 x 0.133 = 114,912 BTU

Therefore, 114,912 BTU would be required to warm up a 40×60 feet shop with 12-ft ceilings to 68°F, given average insulation and location conditions. However, requirements may vary based on individual circumstances.  

Size And Layout of The Shop

The size and layout of the shop are critical considerations when choosing a heating system. A larger shop may require a more powerful heating system. On the other hand, a shop with an irregular shape may need a heating system with adjustable vents. 

Climate and Weather Conditions

Climate and weather conditions vary depending on the region where your shop is located. If the climate is cold and snowy, you have to choose a heating system with higher BTU output to maintain a comfortable temperature. 

In contrast, if your shop is in a warmer region, you will need lower BTU output.

Insulation and Ventilation

The insulation and ventilation of your shop play a vital role in the efficiency and effectiveness of the heating system. If your shop has good insulation and ventilation, you can use a smaller heating system. 

If your shop is poorly insulated or has inadequate ventilation, you may need a larger heating system to keep the temperature comfortable.

So, make sure you take into account the condition of your insulation and ventilation when choosing a heating system. One effective way to improve insulation is by using 2×8 ceiling insulation.


The energy efficiency of the heating system is also an important consideration. It can impact the cost of operating the system over time.

A more energy-efficient system may have a higher upfront cost, but can save you money. Also, if you’re planning to use a gas heater in your shop. Then make sure you have the right gas line size to ensure efficiency. 

Suitable Heating Systems for A 40×60 Shop

There are many types of heating systems that are suitable for a 40×60 shop, each with its own set of advantages and disadvantages. You have to choose the system that suits the best for your 40×60 shop.

Now, let’s learn about some of the most common types of heating systems.

Forced Air Heating System

Forced air heating systems utilize a furnace or heat pump to heat the air. Then the air is circulated throughout a building via ductwork and vents. These systems can be powered by electricity, natural gas, or propane.

It can heat a large space quickly and evenly. Nevertheless, it can produce some noise, and the installation of the ductwork can be difficult and expensive. Forced air furnaces will cost you around $4,000–$8,000.

Radiant Heating System

Radiant heating systems work by using hot water or electric heating elements to warm up the floor or walls of a building. Then it in turn radiates heat to provide warmth throughout the space.

Compared to forced air systems, radiant heating is generally considered to be more energy-efficient since there is no heat loss through ductwork. Additionally, this type of system provides a consistent and comfortable heat.

This heating system may cost from $13,800 to $48,000 depending on several factors.

Infrared Heating System

Infrared heating systems work by using electric heating elements to produce radiant heat. This heat is then directed toward the objects and people in the room. These heating systems are usually cheaper than radiant heating systems, and they provide a comfortable heat without drying out the air.

However, they are less efficient than radiant heating systems, and they can only heat the objects within their line of sight. Price range of an infrared heating system is from $100 to $800.

Ultimately, choosing the ideal heating system for your 40×60 shop will depend on your unique needs and preferences. It may be necessary to seek guidance from a heating expert to determine which system would be the best fit for your specific circumstances.


What Size Heater Do I Need for My Shop?

The size of the heater you need for your shop will depend on the size of your shop, its insulation, and your desired temperature. It’s best to consult with a heating professional to determine the appropriate size for your specific needs.

How to Maintain A Shop Heater?

To maintain a shop, regularly clean the heater and its filters and check for any signs of wear and tear. Also, service your shop heating system  annually by a professional. Regular maintenance of a shop heater can help to extend its lifespan and ensure that it operates safely and efficiently.

What Is The Most Economical Way To Heat A Shop?

The most economical way to heat a shop is insulating the shop and choosing an efficient heating method. For small shops, electric heaters are a cost-effective option. Propane heaters are suitable for larger spaces, while radiant heaters are good for heating specific areas.

Final Words 

To conclude, heating a 40×60 shop requires careful consideration of factors like shop size and layout, weather conditions, insulation and ventilation, and cost and efficiency. Various heating systems like forced air, radiant and infrared are suitable options.
