First Kerosene Heater Test in 10 Years 

I started up my dads old M100d last year. Had to replace the igniter/spark plug. It had sit in the barn for over 15 years and was dirty. Cranked right up. I checked the serial number and it is a 96 model with 90K BTU's of heating capacity. These believe these units were made by DESO. Pretty simple devices that heats up my workshop in no time. Yesterday I was out in the garage. It was 40 degrees and raining outside. A toasty 75 degrees in the shop. My garage/shop is 45x20 with 12 foot high doors and no insulation. Roof height is 14 feet at the top. My father used this garage to keep his motor home in. It is a metal building with a concrete floor and zero insulation. Needless to say I love the heater.

I have a 250,000 BTU Reddy heater. It wasn't used in over 25 years and a full tank of Kerosene remained. It fired up immediately and I never had a problem with it. I'm still using the same tank full. I'm glad it was full because I must of paid about 1/3 less for the fuel when I bought it.

We have one of these in our shop and we run straight diesel in it and it works fine. Alternatively you could run 1 of gallon of gasoline and 4 gallons of diesel, I think 5 gallons is about what what ours holds ... haven't tried it but old videos seem to say it's possible.

You should drain the fuel out (there should be a removable plug on the bottom) and put some clean fuel in it and add 1 ounce of stabil per gallon to clean it out while it's running. Probably check the filter and replace it if need be.

Faulty photocell, soot covering photocell, or bad connection (overheated solder joints?) are what I would suspect. Good luck tracking down the cause.

Yes, a simple and cheap repair. The link is in the description.

that is a sign of a bad photo cell or you have pulsing going on, replace fuel lines and fuel cell and go from there

My grandpa had one back in the late 80s early 90s. It heated the garage in minutes!!!

I have the same one and rarely use it. Got it out plugged it in and does the same thing ....found out the plastic cover on back was cracked and not letting the pump to build enough pressure

Interesting! Do all Reddy heaters have that horrible motor buzz? I have two Reddy R70 heaters with that same buzz. However I have a Remmington 115k and a propane torpedo heater that don't make that noise

Thanks. I'll make another video tearing it down and inspecting the components.

Did you ever find out what was wrong? I just got one of these for free and it does the same thing. I haven't taken it apart to clean yet though.

We found out that choking it while a cold start helps it fire quicker.

I have this very same heater and mine does this very same problem now.

Its getting cold out now and I pulled mine out from 4 years ago. Aiming to save on heating it didnt run right. I purchased a rebuild kit here www.torpedoheat.com/ With the new parts and about an hour labor its running nice and hot but !!! I am still using the old fuel. Go figure. Thumbs up !!

spider built a nest in the photo cell. clean it it will work fine.

will not run with the cover

Mine turns on for a minute or 2 then keeps turning off

Not-so-reddy heater after all lol

I’m going to try it one more time One more time One more time

can I use diesel in a ready heater 55 thousand btu?

GOT 3 of these old skool baby dolls, HAD TO BYPASS THE RESET BUTTON on it, because it was doing what yours was doing kept flaming out for no reason,,, NOW ITS A HAPPY REDDY HEATER... like the older reddy heaters NO ELECTRONIC SHIT CIRCUIT BOARDS TO DEAL WITH.........
