On the body of the Heater you also have side accessory doors. One of them features a battery compartment and a gas accessory quick connect port. The other includes a multi-purpose storage compartment for gloves, documents, power cords or fishing tackle box.

Compatible with Buddy FLEX Cooker

This heater has a connection for yet another great product of this brand, the Buddy FLEX Cooker that they sold separately. Note that the Cooker must be used with the Heater, but the Heater can be used on its own. The picture below shows how they look when attached to each other for transportation:

When the Cooker is on, then the Heater is on Accessory mode so it does not heat. Here you can see them in work.

Accessory carry bag

They offer a carry bag that can be ordered separately. It is nicely designed with multiple pockets from outside, and it is deep so that both the Heater and the Cooker fit inside easily.

Who is it for

Regarding the best use & power, in specifications the manufacturer writes it is for up to 275 ft² (25 m²) of area. I would say that this strongly depends on what kind of closed space you use this heater in. So it is best to test and see how it works for you.

With the tank capacity of 1 lb, its run time at Max BTU is 2 hours and and Min BTU it is 3.5 hours, so you get some idea of what to expect. 

Regarding the weight and dimensions, the heater is quite heavy with its 11.02 lb (5 kg). It may also look bulky, you will see the numbers below, but this is an item for places with a car access so this is not so important.

I see it as a great product for hunters and fishermen, for heating tents in basecamps, and for family camping as well.

Regarding the price, it is in the range of its closest competitors, a fair price for such a quality product. 


Specifications

  • Type: propane heater.
  • Weight: 11.02 lb (5 kg).
  • Dimensions (L x W x H): 15.35 x 10.95 x 16.54 in (39 x 28 x 42 cm).
  • Output: 11000 BTU.
  • Heating area: 275 ft² (25 m²).
  • Fuel consumption/Burn rate: 0.121 Gal/Hr.
  • Maximum elevation use: 9000 ft (2740 m).

In summary, this Mr. Heater Buddy FLEX Portable Radiant Heater is beautifully designed and with a number of unique and patented features.
