Review: All it's not Well... - This product can not be sold in Europe, the product has pass the tests to get the CE certification, it was sold to me in Portugal, trought desertcart.es by All is well company it was defective, they offered me to buy a new one with a 50.. euro credit, now the European company that could fix it refuse for liability reason, I am stuck with a large use less purchase, All it's not well... Review: Mr. Heater Big Buddy Heater, 4,000 to 18,000 BTU Propane Heater - I purchased this product because despite running two very efficient and very expensive heat pumps, my home was always cold. Additionally, my electric bill was becoming more and more outrageous. I was hopeful that the Mr. Heater Big Buddy Heater would at least be able to heat up my bedroom and also be able to heat up the master bathroom for showers and such. That said, I have been extraordinarily happy with the performance of the Big Buddy Heater. The heat output can be tailored to the exact needs of the moment, there are no unpleasant smells produced by the heater, and the fact that it puts out infrared heat makes it very pleasant to be near when the room is chilly. The heater is very easy to start with its piezo igniter and the heat produced is infinitely adjustable from low (4,000 BTU) to high (18,000 BTU). While the model I purchased did not come with the built-in heat distribution fan, I was able to add the factory fan with a purchase through desertcart (Mr. Heater Big Buddy Heater Back Cover Fan (E78404) (www.desertcart.com/gp/product/B09S16JL8G)). I would recommend that everyone purchase the new Big Buddy Pro model that does come with the factory built-in fan. I use the Mr. Heater 6-Volt Power Adapter to power my heater's newly added fan (www.desertcart.com/gp/product/B000HE6OAE). I also use the Mr. Heater 12' Hose with Regulator & Quick Disconnect (F271803) (www.desertcart.com/12ft-Big-Buddy-Hose-Regulator/dp/B000UC7966) to supply low-pressure propane to my heater. I have found the Big Buddy Heater to be very efficient in its use of propane. It has saved me a great deal of money by not having to use my heat pumps to stay warm. In summary, I have been overwhelmingly happy with my Mr. Heater Big Buddy Heater purchase. I have had no problems of any kind with the product. Further, I have been so happy with the performance of the heater that I have purchased a second one. Mr. Heater should be very proud of this product. ## Features - Propane Tank Heater: Heat up your camping or picnic area, porch, shed, and more with a handy propane heater with variable settings for custom warmth anytime, anywhere you bring it - Heat Levels: Gives off 4,000, 9,000, or 18,000 BTU per hour with a 450-square feet heat range and can be used with propane tanks up to 40 lbs with the use of an additional hose and filter - Simple Usage: Single control start knob allows easy usage with a piezo sparking mechanism for reliability with automatic safety shutoff in case the patio heater tips over - Possible Connections: Can connect to a pair of 1 lb propane tanks with 2 swivel regulators for a remote gas supply for your outdoor heater; Hose, filter, batteries, and propane are not included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q82MG8S | | Brand | Mr. Heater | | Brand Name | Mr. Heater | | Colour | Red | | Country of Origin | USA | | Customer Reviews | 4.6 out of 5 stars 5,469 Reviews | | Form Factor | Cabinet | | Fuel Type | Propane | | Global Trade Identification Number | 00089301004825 | | Heat Output | 18000 British Thermal Units | | Heating Coverage | 450 square_feet | | Heating Element | Radiant | | Heating Method | Forced Air, Radiant | | Included Components | HEATER, MANUAL | | Indoor Outdoor Usage | Indoor, Outdoor | | Indoor/Outdoor Usage | Indoor, Outdoor | | Item Type Name | propane heater | | Item Weight | 5.9 kg | | Manufacturer | Mr. Heater | | Max Temperature Setting | 900 Degrees Fahrenheit | | Min Temperature Setting | 40 Degrees Fahrenheit | | Model Number | MH18B | | Mounting Type | Floor Mount | | Number of Items | 1 | | Part Number | F274805 | | Power Source | Gas Powered | | Power Source Type | Gas Powered | | Room Type | Bedroom, Home Office, Study Room | | Special Feature | Portable | | Special Features | Portable | | UPC | 089301004825 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Mr. Heater - **Colour:** Red - **Form Factor:** Cabinet - **Indoor/Outdoor Usage:** Indoor, Outdoor - **Special Feature:** Portable ## Images ![Mr. Heater Corporation MH18B Portable Propane Heater, Red - Image 1](https://m.media-amazon.com/images/I/81OAv4w78aL.jpg) ![Mr. Heater Corporation MH18B Portable Propane Heater, Red - Image 2](https://m.media-amazon.com/images/I/71dcYr4LYYL.jpg) ![Mr. Heater Corporation MH18B Portable Propane Heater, Red - Image 3](https://m.media-amazon.com/images/I/81oRsiELkRL.jpg) ![Mr. Heater Corporation MH18B Portable Propane Heater, Red - Image 4](https://m.media-amazon.com/images/I/71cHSDIMwKL.jpg) ![Mr. Heater Corporation MH18B Portable Propane Heater, Red - Image 5](https://m.media-amazon.com/images/I/71svuVHmSUL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐ All it's not Well... *by F***Y on 17 October 2025* This product can not be sold in Europe, the product has pass the tests to get the CE certification, it was sold to me in Portugal, trought Amazon.es by All is well company it was defective, they offered me to buy a new one with a 50.. euro credit, now the European company that could fix it refuse for liability reason, I am stuck with a large use less purchase, All it's not well... ### ⭐⭐⭐⭐⭐ Mr. Heater Big Buddy Heater, 4,000 to 18,000 BTU Propane Heater *by J***S on 6 April 2024* I purchased this product because despite running two very efficient and very expensive heat pumps, my home was always cold.
