The Mr Heater F232000 has two heat settings and efficiently heats a room of up to 225 square feet, so it packs a punch. It has a low-oxygen safety shut off so you can leave the heater on overnight or when you’re out of the room safe in the knowledge that it won’t overheat. 

It has a fold-down handle to reduce storage space, which is handy when on the move or when it’s not needed. Its heating surface is made from durable porcelain and directs radiant heat over a wide area while maintaining the desired temperature. 

Integrated into the design of the Mr Heater F232000 is a high-quality ceramic burner tile that offers shock-absorbing insulation. This is a highly durable option and if it needs replacing, this can be done easily.

The Mr Heater F232000 has got a tip-over safety shut off, so it’s perfect for outdoor use such as camping, though it’s important to follow the usage instructions carefully. If you trip over it in the dark to your heart’s content and it’ll automatically shut off, so that aspect makes it a great option a small – not to mention busy - area. It’s a sturdy machine for one so portable, which is why so many people take it on camping trips. It connects to a propane tank that you buy separately.

Mr. Heater F232000: Design

With a larger heating surface, fold-down handle, swivel-out fuel connection, and an easy-start four-position control, Mr. Heater is a pretty slick, compact model with a smart, retro look 

Mr. Heater F232000: Performance

The Mr Heater F232000 is approved for indoor and outdoor use, with many customers choosing it as a safe, efficient camping heater. It’s clean-burning and nearly 100-percent efficient. It runs for three hours at maximum output, and heats up the coldest spaces quickly and cost-effectively. On low heat it gives up to six hours of output, which is pretty amazing. You can catch your dinner, skin your dinner, cook your dinner and eat it without having to check how your heater’s doing. It’s a great model to take to your weekend cabin to keep you cozy.

It’s a fairly small heater so you do take this into account when buying. If you are needing to heat a garage, say, or room that is larger than 200 square feet or if you have particularly high ceilings, this heater on its own may not be sufficient.

Something to bear in mind if you’re taking this model camping is that at altitudes over 7,000 FT above sea level the heater may shut off. 

Mr. Heater F232000: User reviews

One user reported buying this model to take on a camping trip when the temperate hit a low of -8°F.

Other customers say that on a low setting the main heating thermostat didn’t come on at all – even during below freezing temperatures. 

Users love the fact that the Mr Heater F232000 makes no sound at all – which makes it ideal for a bedroom or small space – and it doesn’t give off any kind of smell, unlike some models. Put it this way, there’s a reason why 75% of over 2500 reviews on Amazon are five-star.

Should you buy the Mr. Heater F232000?

If you’re looking for a powerful and flexible heater, especially for outdoor use, definitely.
