If you use a LP (20 lb or larger) it should be outside for safety reasons. The smaller 1 lb cylinders can be used inside in many regions though.

Quite frankly I don't understand what the other person is saying. Last winter I had a Mr Heater and it kept my 5th wheel warm, but I want something to kept it really warm so I am going to get the Big Buddy Heater. These heaters are great and safe. If you do buy one the tank has to be outside. Go to the Mr Heater and they will tell you what all you need and what to do. Good luck I think the Mr Heaters are great!!!!

It operates perfectly/uses both elements with only one hose and fuel filter or one camp cylinder (low/ medium heat setting uses one element, high setting uses both elements).

When you buy the hose make sure to also buy the fuel filter - you need that to connect the hose to the heater.

No need for more than more than one hose, unless you need a really long continuous burn time without changing tanks and only have 20 lb tanks.

ONLY CONNECT 1 OF THE 20LB TANKS PER USE ! THEY ARE NOT DESIGNED FOR 2 OF THE 20LB TANKS ! MAX SIZE IS 1 20LB. TANK OR 2 1LB TANK. THERE IS A CAP ON THE OTHER CONNECTION SO PROPANE WILL NOT LEAK OUT OF THE OTHER SIDE. : )

answer 1
Yes in most cases but, in bed room be especially careful of flammable items like bedding etc. Leave plenty of room around the heater to be safe and not recommend for normal use only under extreme emergency conditions as heater should be watched and you need proper ventilation, no closed small rooms as it uses oxygen to burn. Better to place the heater out side the room in an open area.

Mr. Mervyn,

A new class of heater came into being about 10 years ago.

They are called "ventless" heaters because they are 99.9 efficient, they send nothing up the chimney, because there is no chimney.

The ALL have a low oxygen sensor, if the osygen in a room runs low they turn themselves off - THUS you can yse them anywhere. As I write this I am living & sleeping in a micromotorhome with one of these heaters as my ONLY (well, besides my electric blnket) source of heat. I go to sleep every night knowing that i will wake up in the morning, because I have purchased, installed and used more than three dozen of these heaters. --tim--

answer 3
in answer to the question concerning the converter hose from mr. heater big buddy or buddy heater to 20 lb propane tank.

I bought a 4 foot hose that converts any 1 lb propane fitting on any appliance that accepts the 1 lb propane cylinder to the 20 lb propane tank.

While it is not 12 ft long, (sometimes it does almost seem a bit short) it cost less than the 12 ft hose.

wal mart may carry the 12 ft hose but if not, most hardware and propane stores will.

Concerting the question of the 6 volt converter for ac opperation of the big buddy fan motor;
try wal mart first, but if they don't have one,
Radio shack or the local electronics shop can provide a 110 volt ac to 6 volt dc converter for the fan of the
big buddy heater but it should have a more robust current rating in the range of .25 to .5 amps. Check your owners manuel for this info. Remember that you need to make sure that the polarity (postive to positive & negative to negative) agrees between the jack of the big buddy heater and the ac to dc converter.

those willing to wait on shipping can also order from the factory.

Depends on what combustible material is in the shop. The heater is reasonably safe but still uses flame. The back of the heater can usually be placed close to a wall but, the front radiates heat so allow a few feet (at least 4 or 5 in my opinion) to be safe.

It won't serve as an outdoor heater. Any amount of wind would disperse all of the heat that it generates.
