Really depends on the BTU's of the heater as the clearance to combustibles will change somewhat. Most have minimum top to ceiling clearance anywhere from 2-5 inches when mounted horizontal. These are also low intensity residential rated heaters. You should be fine with 9' as I believe code in...

My garage is 24 x 24 with 10' ceilings.The big thing with these units is the clearance to combustibles. Also has to be certified for residential use if the garage is attached. My clearances are 2" to the ceiling and 48" below. You can mount horizontal or at 45 degree angle. The lower your...

I have a SRP 45k unit and the fan is fairly quiet. Sounds like a bath fan. The deflector groans a bit during heat up and cool down but that's about it. You may have a motor imbalance causing the vibration. IMO you shouldn't need isolation mounts if it's hanging from chain. Question, does your...

Nice job!!! I just installed one those exact tube heaters in my shop. Just a comment on your rusted flue pipe.......I was told by the guys I purchased it from to make sure to have some downward slope to the flue pipe in order to drain any condensate which is very corrosive. Look forward to more...

Well I think I've got the fan sizing down and how and where it will exit the building. Now I'm starting to think about a fresh air intake. My space is fairly tight but I'm sure there is some leakage. The radiant tube heater has a concentric vent drawing fresh air from the outside. Was thinking...

Thanks, never thought of it that way.

Thanks Was looking at a de-humidifier but the cost to run it was high. leaning towards a ceiling mount fan vented through the sidewall. Just have to decide on the size

No machine tools but I do have window condensation problems and I have noticed some small areas of mold growth. The humidity levels have been as high as 70%. Thought it would be a good idea if I could exchange the air through out the day to try and lower the humidity value.

Thanks for the reply..... I was leery as to the advertised CFM as well. But while doing some research I found that most of the big names are all certified to meet the HVI (Home Ventilating Institute) standards for sound and advertised CFM ratings. The advertised CFM is rated at 0.1 static...

Looking to add a basic fan to my garage in order to remove some of the humid air that occurs when the cars come in during the winter. We knock most of the snow off but some still eventually melts inside and then squeegeed out. I keep the temp at a constant 50 degrees with a radiant tube...

Hi there, Ended up installing a heat shield made out of .060 aluminum. Made a drastic reduction in ceiling heat. Bring on winter!

Your clearances to combustibles are usually measured from the nearest point to the combustible. E.g. 18" from the fan housing not the unit heater. Your manual should specify this.. Gas line size is determined by the gas load based on the appliances being feed. If this is a dedicated line you...

Hi, I just installed a SRP unit with a balanced or concentric flue. 2" flue runs inside the 4" fresh air intake. The 4" fresh air pipe was zero clearance through out.

Anyone??

Hello, New to this forum and really enjoy the great info here. I just installed a 45,000 btu SRP tube heater. Minimum clearance to the ceiling is 3" at a 45 degree mount. Installed at 4.5", ceiling is osb. When it runs the ceiling temp at the leading edge runs at 175 degrees F which seems hot to...
