How Long Will a Mr. Buddy Heater Run on a 20Ib Tank?

by Sharin

Have you ever wondered how long will a Mr Buddy Heater run on a 20 Ib tank? So, you’re not on your own. This is a typical question for most buddy heater users. But the solution is not that straightforward. It all depends on a few factors, such as the size of the tank, the outside temperature, and the heater’s BTU rating.

Generally, a 20 lb tank will last anywhere from 43 to 48 hours. However, if it’s a cold night, you may only get 40 or 43 hours of use out of it. And if you’re using a high-BTU heater, your tank may only last 35 or 40 hours.

So, how can you determine how long will a Mr. Buddy heater will run on a 20 lb tank? In this article, we are just about to reveal that.

Here we have provided all the details you need to know about a Mr. Buddy Heater on a 20Ib tank so that you can have a clear picture of how much fuel you will need to carry for your next camping trip.

So, without further ado, let’s get started.

Mr. Buddy Heater Runtime – 20Ib Tank

Depending on the model of Mr. Buddy Heater you have, the runtime can vary significantly.

For example, a 9000 BTU model will give you a minimum of 20 hours of runtime and a maximum of 100 hours of runtime on a 20Ib tank, while an 18000 BTU model will give you a minimum of 40 hours of runtime on the same size tank.

So, if you’re looking for a heater that will give you long-lasting warmth, choose a model with a high runtime rating. Otherwise, you may have to constantly refill your tank to keep your space warm. 

Mr. Buddy Heater Runtime – Low and High Comparison Rate

Think about how often you use your heater and how long you need it to run. If you only need it for a few hours, then the low setting may be the way to go. 

On the other hand, if you need to run your heater a little longer than usual, especially for an outdoor heater model, you must use it in a high setting.

Yes, it will burn most of the fuel, but you can still utilize your buddy heater effectively.

Here’s a full comparison of the buddy heater runtime on low and high settings,
