10 Best Heaters For Sheds Reviewed

When winter is drawing close you have to keep the shed cozy and comfortable all through the wintry weather. It is only someone that has experienced the bitter winters who can truly understand the importance of heaters for a shed, garage, and patios.

In this guide, we will look at the best heater for an outdoor shed that will keep you warm as well as keep you safe. We’ve considered the performance, design, size, and cost to give you our top and favorite recommended heaters for a shed.

Regardless of what heating alternatives you chose out for your shed, there are two things you need to do before you purchase a heater for a shed. First, you must make sure that your shed is well and nicely insulated, insulated shed saves energy cost than when not insulated.

Secondly is to calculate the BTU’s required to heat up your shed especially if you want to buy a propane heater, it is compulsory for you. But if you’re buying electric heaters it may not really be necessary.

Therefore, with your shed well insulated, you can now go ahead to place an order for your best heater for a shed.

How Much BTU’s Do You Need To Heat A Shed?

Before buying any heater for a shed, you need to first understand the computation for knowing the right level of BTU for your shed. BTU stands for ‘British Thermal Unit’, this is the unit used to signify the value of heat that can be produced.

However, since there are different heaters with different power, different prices, and BTU per hour, choosing your best heater for a shed should not be on the above features mentioned above rather it should be on what type of heater has the required BTU to heat up your shed during different temperature conditions.

How To Compute Your Shed BTU?

  1. Measure out the length and width of your shed and multiply it (L x W) to get the square feet area of your shed or room.
  2. Divide your answer in number by 200 and multiply you got after division by 9000 if the is not insulated or multiply by 6000 if your shed is insulated. Whatever figure you get is the estimated heater BTU your shed needed to heat up per hour. Let’s see some examples below.

Length of a shed = 20ft

Width of a shed = 20ft

For uninsulated Shed

            20ft x 20ft = 400sq.ft

            400/200 = 2

            2 x 9000 = 18000BTU

That’s to say that a shed of 400sq.ft that is not insulated required approximately 18000BTU heater to heat up per hour.

For Insulated Shed

            20ft x 20ft = 400sq.ft

            400/200 = 2

            2 x 6000 = 12,000BTU

So for a shed of 400sq.ft that is well insulated will require approximately 12,000BTU to heat up the shed per hour.

For those who want quick and easy the automatic calculator will help you do that fast and swift without cracking the brain.

This is highly necessary especially if you’re going propane. I have explained in detail how to calculate BTU for a shed.

The thermostat allows you to have better control over the heat intensity and temperature of the heat. With this feature in place, you can leave your shed and be rest assured that the temperature will be maintained at the set temperature.

What Type Heater To Use for A Shed?

Well, there are many types of heaters you can use on a shed such as electric heaters, propane heaters, kerosene heaters, and Fire. Normally people tend to use open fire but it is not the best because can cause a serious fire hazard and therefore will not be left unattended.
