Welding a Fireplace Heatalator

[Oldpath05]

I dont see how silicone will work on anything that has high heat, maybe on chimney parts, 600° comes quick and wood fire is hotter then that, just look at that heat distortion on your heatilator. Welding later over silicone will be harder when it already is hard to weld.

I hope you have CO sensors in the house if you are burning a fire with a crack in the inner side of the double wall shell.

I know you said you don’t smell anything but CO is odorless and deadly.

I had thought of that. No, I don't have a CO detector. If there isn't even a hint of smoke from a wood fire, why would there be CO? I never heard of CO detectors for wood burning appliances. Am I missing something? Thanks.

You are probably burning hot and fairly complete. Nonetheless... Sources of Poisonous Carbon Monoxide: Fireplace Flames

CO blends in the air so the sensors can be mounted anywhere. I use the type that plug into a 120V outlet. Simple, take them out of the packaging, put the backup battery in (if equipped) and plug them in.

The CO detectors look like a smoke detector. Installs like a smoke detector. Usually stocked on the same shelf at the stores. Prices range from 15 to 30 dollars usually. Well worth it if you have fireplace or any kind of gas burning appliances in the house.

Thanks. What a poorly put together article though. Firstly, a distinction should be made between wood burning fireplaces and otherwise. Too many articles out there with generalizations and no facts. How many people ACTUALLY died or became sick from C0 from a woodburning fireplace and what was the cause?

I guess I didn't poison myself when my chimney screen was 80% blocked despite the smoke that came into the house whenever the glass doors were opened.

The house isn't tight which I kind of like for air quality. And not another stupid piece of equipment running in the basement 24/7.

I am in the security business so if I come across a CO detector on sale, I may consider it, and in five years may actually get it hooked up!

I have. Although with wood burning stoves you also have the issues with the production of aerosol furans

I know an elderly gentleman who blew the doors off his fireplace when he inadvertently put his wifes discarded purse size aerosol hair spray can in the fireplace. But never heard of aerosol furans. Can you please elaborate on your experience?

Splitting headache. Started the day I started using the stove. Ended two days later when I stopped using the stove.

Thanks.

And the reason was . . . .

I am alive only because of a properly working CO sensor. Not CO from a wood stove, but the danger is there. Cheap insurance in my book, but everyone can choose to ignore the issue for themselves and their family.

Wood Burning Stoves and the Risk of Carbon Monoxide Poisoning

The OP was using a Heatilator with a large crack in the shell where the room air passes through, the concern is valid.

 

[Rock knocker]

A minor flue leak that was for all purposes invisible and did not emit visible emissions.

Now that the CO is under control, I'm still waiting to see how this heatilator is going to be fixed, sounds like I have time to make some popcorn............

I was fixing a mag drill this afternoon, looking for a #6-32 nut in my bombed-out workshop only to come across a C0 detector. Brand new, something I found somewhere years ago on a job site. Maybe it's a sign. How do they work anyway and do they expire?

The alarm contacts are not provided on that model, as seen on the silk screened pcb, but an ac/dc input and terminals marked a&b. I don't see any sounder, just LEDs indicating PPM. So, a new mystery!

But something else I was pondering. Why are there so many rods for arc welding but not different wire (except for size) for mig on ferrous material.

"But something else I was pondering. Why are there so many rods for arc welding but not different wire (except for size) for mig on ferrous material."

Good question, there probably is more different kinds of stick rods, but at the shipyard theres, 70s, 100s solid wire, 71t, 101tm flux core, SS and SS to steel flux core, SS and SS to steel solid wire, then aluminum wire, copper nickel wire, so that's about ten different kinds of pulse/mig wire. With stick there are all position rods and then theres flat only rods and on and on, so there might be more kind of stick rods.

When testing a CO detector, couldn't that be done with a running car in a garage, preferably when your on the outside.

Is flux core still used with gas?

If fireplaces represent such a danger, what about using a propane or natural gas stove? Where do the products of combustion from that go? They say you can't use a gas BBQ inside, but you can use a gas stove top. I mean, who would want the smoke, but that's not the point.

Fire Places have been around much longer than furnaces. Both have killed their share. Personally I enjoy the wood heat heat. As for your fireplace, Zap her together and don't look back. Buy a new $8.99 CO detector with alarm and this thread will die of natural causes. :thumbsup:

Duel Shield 71t flux core has have 75/25 welding gas, self shielding flux core does not need gas which makes it more portable but more spatery and more smokey than 70s6 solid wire, but I dont what smokes more flux core or stick.

This heatilator must be mostly for enjoyment because getting kinda late in the heating season to fix the heating system, must have a 2nd source of heat hye?

A fireplace is meant to be a source of space heat, a stovetop is meant to heat food. The potential differences is BTUs are measured in the tens to hundreds of thousands.

I just took the temp with an IR thermometer of the top of my wood stove. 900 degrees F. A quick google search indicates they can go up to 1200 degrees F.
