Propane Powder coat oven conversion MR. Heater.

This is just what I was looking for. Thanks for all your hard work and research.

[@boldcitydesignsjax]

No problem! Thank you for appreciating it!!

[@LHGII]

@@boldcitydesignsjax hell yeah bout to build one..

[@matty332010]

Thx man, you have the best video i've seen yet, about hooking these heaters up.

[@jimmieomalley3383]

Thanks man. I am building the exact same size and propane fired as well...this valve will help a lot!

[@burnone6457]

I built a powder coat oven with the dimensions of 4ft ( width ) by 4ft ( length ) x 7.5 feet ( height ) 3 and 5/8 inch walls.... Skinned on inside with mineral wool insulation . I have a 250kbtu -400kbtu propane heater ( Mr heater model number MH400FAVT ) heating the oven . For my controls system I have a inkbird ITC-106PH PID hooked up to a inkbird solid state relay that controls a gas solenoid that I plumbed into the heater itself. The oven has a k style thermocouple that I have tried in different locations in the oven to try to fix my issue. My issue is that I have a large flucionation in temps when my oven gets to 400 . It actually overshoots and heats to about 430 degrees . Now another issue is that when the temp drops below 400 and calls for heat I can hear the gas solenoid opening and heater getting power and turning on the blower but the gas doesn't ignite for about 4 seconds which causes more temp influx I imagine but not sure . I have tried the PID in auto tune mode ... Factory settings ... And a couple pid adjustments recommended by a youtuber. I'm wondering if there is a way to maintain the temp better. Is my propane heater too big ? Do I have to wire a jumper of some kind to have constant ignite in my torpedo heater ? Do I have the wrong heater for the application ? This heater does have an internal thermostat . Thanks for reading this and thank you for your time and insight .

[@boldcitydesignsjax]

It has held up well. It’s currently being used in another shop and I’m in the process of building a new smaller oven.

Did you got a video cinnecting the wiring bro?

[@lawrenceakana6874]

Thanks, I’m planing on building an oven and new to the powder coating seen. Your video definitely helped me. Where did you get the heater and all the parts and pieces that are involved with the heating element?

So did that small of a heater work for your oven I have a 4x4x6. same setup but a 125000 btu heater.. it takes 4 mins to heat to 400 degress..was told not to use anything smaller.. just ordered a commercial Carlin LP burner.

[@boldcitydesignsjax]

It did work, took about 10 mins to heat. Probably wasn’t the most efficient. I would go with a bigger heater if I ever built another oven.

[@Dishtech48]

@@boldcitydesignsjax Yea.. I just bought the Carlin Commercial Burner and installed it.. very heavy duty , Digital read out.. I drilled out orphis to 150000 btu it takes about 4 mins to get to 400 ! I might drill out little bigger.. it goes to 275000 btu. Really like this set up.. Thanks

[@rjthomasindyusa]

How did the Carlin burner work out? Did you use there temperature control modular and thermocouple?

[@Dishtech48]

@@rjthomasindyusa I used an Auber PID controller ! Very nice controller..It is digital read out. I set my temp to 400 and it is wired into a plug in , that the burner plugs into it.. and it kicks on and off the power too the plug in... works awesome.....

[@Saltyglass]

I have a question on how you hook it up to your pid, are you using powder from 12v converter to the pid and then attaching your solenoid?

[@kevinshively]

It's my understanding that when the PID gets a signal from the thermocoupler for heat it triggers the solid state relay which activates the "powerstrip" or 125v outlet. When the outlet gets power it sends voltage to the heater to ignite and also power to the solenoid to open up the gas flow.

[@kevinshively]

I meant 110/115v outlet. Not 125v

[@boldcitydesignsjax]

Kevin Shively is correct.

[@burnone6457]

I have a mr heater 250 k to 400 k hooked up to my PID... It has an auto ignite but it's not continuous ignite . When my PID calls for more heat it takes a little while for my heater to ignite it . Which causes overshooting of temps . I just need it to ignite when the pid opens the gas valve. Do I have to change any inside wiring

[@boldcitydesignsjax]

I would think not.. should function the same.

[@mindas33degree]

Have few questions as planning on building oven shortly and can see you have quite a bit of experience with it already. My oven side is determined by space I've got and products that will be placed there for coating so external dimensions will be 3.4x7x9ft (W-H-D). The door is at the narrow side. Do you reckon the 60k btu heated is sufficient? also, where would you place the blower in the middle or the back and then use the fan to blow the heat from the ceiling down above the door? Where to put the exhaust pipe then? Finally it is build outside... And insulation wise or stud width I would plan to use the same thickness as yours. Would really appreciate your advice on this! Thanks!

[@boldcitydesignsjax]

I would step up to the 120 btu. That way it doesn’t struggle to keep up. I would still place it in the bottom. Heat rises we all know. Let the heat rise and force the cold air down and out of the exhaust at the lowest point. That way there is always fresh hot air and forcing out the coldest air first.

Oh yeah that really did help. Much appreciated. Your right on about old info out there. I hope you post link in comments to the valve, that'd be handy. Also what pid are you going to use? Thanks again, I am planning a build myself and have obviously been looking.... Your oven looks like it is coming along as well. What insulation are you planning on using?

[@boldcitydesignsjax]

Truegrit Scott also I’m using an Inkbird PId off amazon. Also the insulation is mineral wool insulation from lowes.

[@truegritbulldog]

Bold City Designs mineral wool... Sounds like rockwool from my hydro growing days. Going to look that up now

[@hiimbaby2630]

Is it possible to use just Mr heater for powder coating in the same size oven as your without the electrical heating elements ?

[@hiimbaby2630]

Can you also put a link on where you bought the LP Valve

[@boldcitydesignsjax]

@@hiimbaby2630 no you don’t need the electric elements. Propane or LP gas works just fine. The valve came from amazon. Search LP gas valve. I’ve shared the link several times in the comments section I just don’t have it handy now.

Bold city desings i have a small oven its 3 w 4 h and 8 feet deep i have the electric box control i have 3 electric elements in my oven but electricity its more expensive than gas i have a thermocouple its what control the temperature do you think its posiblem use that box with the thermocouple and use with the gas heater i dont know if i can add something in my gas heater to control the temperature with the box so when my oven reach 400 dgs the oven turn dowm and when the oven need more temperature turn on the flame can u understand my point sorry my english is not very weel

[@boldcitydesignsjax]

Adolfo Lopez if I understand your question yes you can do that. You would need the valve like in this video to hook to your control box so that it could control your gas heater. Although not all heaters will work. It needs to have continuous ignition.

[@adolfolopez8658]

Thanks for answer buddy thanks a lot

[@boldcitydesignsjax]

Adolfo Lopez no problem I hope it helped. Anything else let me know 👍🏼

How long does your bottle last?

Trav B. A 20lbs bottle last me about 2 days(working hours) of non stop running. If you use it periodically and shut it off when your done it would last you a lot longer. Bigger bottle is recommended but it does work great. That’s about 1.25$ an hour to run.

Man you have a awesome idea and thank you for explaining everything. I have one question- when you say converter, what are you talking about? I know you said you will power source.
