Heating a 40×60 Shop: All You Need to Know


Feeling a little chilly in your shop? Need to install a heating system that will be suited for your shop? 

So what about heating a 40×60 shop?

To heat a 40×60 shop you might want to know how many BTU you will require. The number will vary depending on the weather, climate, and shop’s building materials. There are a few heating system options that are available. Furnace, radiant heat system and heat pump being the popular ones. 

This just gives you a hint of what you need to know to heat your shop properly. Read the article and you should have a much better understanding.

How Much BTU is Required to Heat a 40×60 Shop?

The calculation for a heating and cooling system depends on calculating two things. They are calculating how much air you want to add or remove from the shop. 

The initial step is to understand how many degrees you want to raise the inside temperature. And the required amount of BTUs to accomplish that? 

This may depend on numerous factors. For example, the room’s square footage and the climate. The most crucial issue, though, is how many degrees Celsius you want the temperature to rise.

Homeowners can get assistance determining the appropriate size unit by using the various calculators that are available. However, there are certain broad standards that can be followed. A room that is 1000 square feet in size requires 18,000 BTUs. 

So a 2.400 (60×40) sq feet shop will require around  45,000 BTU to heat. Heating a heating a 40×80 shop will require more BTU.

The following formula can be used to estimate your future heating needs:

(temperature change wanted) x (cubic feet of space) x.133 = required BTUs per hour.

The cost to heat a 40×60 shop will depend on the BTU needed to heat the shop. 

What Factors Affect How Much Heating is Required?

You may figure out the exact amount of BTU required for your shop heat. However, there are certain factors that will influence the figure.

Climate and Weather

The climate is another factor that goes into calculating the amount of energy you will use. Warmer temperatures along the southern part of the USA. Which are classified as Zones 1 or 2, and require 30-40 BTU of heating energy per square foot. 

The requirements for heating a shop in Zone 3 and 4 are between 40 and 45 BTU. Whereas the requirements for heating a shop of Zone 5 might reach up to 60 BTU. 

In easy words, the volume of energy needed to change the temperature of a shop is dependent. It has a straight proportional relationship with the temperature of the air outside the building. 

Having heavy lighting outside may affect the heat inside as well. Properly mounting exterior lights can lessen the effect.  

Shop Quality and Material

This energy needed is also affected by the age of the shop. As well as the quality and type of material utilized in its construction. 

The figure must be adjusted accordingly if there are additional windows in the shop. These may let in either more sunshine or cold air. And if insulation is used throughout the entire shop. 

2×8 ceiling insulation will matter for the heating of your shop.

Additional heating capacity is required for older shops. Particularly those that are drafty and/or not well insulated. 

Installers should take into account the layout of the shop and the location of the windows. 

This will help them to calculate the proper temperature regulating loads. This will help them to calculate the proper size of the heating or cooling system.

Heating Systems for 40×60 Shops

We discussed how much BTU you will need to heat your shop. But knowing how much BTU is required is not helpful for actually heating the shop. You will need dedicated heating systems. 

Here are some systems you can look into for your shop.


One of the most typical ways that a room can be heated is by using a furnace. Burning gas or propane to provide heat is the primary function of furnaces. They are perfect for heating shops 

The heat needs to be distributed evenly throughout your shop. For that, you will need an additional require forced-air system.

The activities that happen inside the shop and the amount of foot traffic can differ. Depending on that the ductwork can either be concealed or left exposed.

Heat Pumps

Some people favor heat pumps because they are generally a more energy-efficient alternative to the conventional furnace. They are extremely efficient heating and cooling systems that combine two previously distinct systems into one. Because of its adaptability, you can make use of only this one system throughout the entire year! 

The primary operation consists of bringing warm air from the shop’s surroundings into the structure itself. In order to get rid of the hot air that’s trapped inside, the direction is switched around. 

There are heat pumps that draw their heat from the surrounding air, geothermal and water-based sources. Have a conversation with your contractor to find out which of the available options is the most suitable for your shop.

Radiant Heating System

Radiant heating is another option for your shop. When using it, you will be required to make a selection. A choice between having the heat come from the floor or the ceiling.

Radiant heat systems are usually more practical than forced-air heat systems. Because the ductwork has no heat loss. 

Radiant heat can be distributed evenly throughout a room. You will not need to worry about heating the air inside your shop. Radiant heat will heat the things themselves.


How do you size a heater for a shop?

When determining the size of a heater, the standard rule of thumb is 10 watts for every square foot of space. The NewAir G56 Electric Garage Heater has a wattage of 5600 watts, which indicates that it is capable of heating an area as large as 560 square feet in an easy and efficient manner.

What is the most economical way to heat a garage?

Radiant heating systems can be put as panels in the walls or ceiling, or they can be buried beneath the floor. Instead of heating the air in the room, this system employs infrared radiation to heat the surface that it is attached.

Can I install a heater in the basement?

Yes, you can. In order for your furnace to function at its highest level of effectiveness, it will require an area that has access to natural gas, an abundance of clean air, and adequate ventilation. These essential components can be discovered in expansive areas such as basements.


Now we know all we need to know about heating a 40×60 shop. Knowing how many BTU you will need will help you decide on a system. And the cost of the heating. 

Furnace, heat pump, and radiant system are options for heating your shop. 

Good Luck!
