    flame sensor

    Thanks, I saw that. I don't have the tools or experience to try something like that and make it trustworthy. I'm trying to find out if I can bypass the igniter and use the flame sensor part of this board.

    flame sensor

    I considered that, the burner is already set up for the flame rod, the solenoid works fine if I could get the sensor rod to control it. Wouldn't that be safer, more reliable? I have to be able to turn the gas on to light it, will the thermocouple open if I hold a lighter to it? In my search for...

    flame sensor

    I was going to do that first then someone said all I need is this AD620 IC. The furnace controllers have several other switches I'd have to bypass somehow. They have a purge fan and a flag switch and maybe something else. All this is for is so if the flame goes out the gas shuts off. It will be...

    flame sensor

    I need to make this flame sensor open the solenoid which lets the gas flow to the burner, so If the flame goes out the gas will shut off. If I connect a 3v battery to the solenoid it will open and the gas will flow, my meter says it draws 0.22 amps, The flame sensor puts out a very slight signal...

    DIY radiant heat system

    So So I took the burner out of the old water heater, it still works fine. The calanoid opens the gas when 3 volts are applied. The flame sensor works but I had to order a signal amp module to get it to 3 volts. I have access to some 3/4'' stainless steel tubing, enough to build it as in the...

    DIY radiant heat system

    Thanks, makes sense. Will depend on cost and what I can find.

    Something like this? What about more tubes smaller diameter? This would take a lot of brazing.

    ''fins on the inside and outside'' ? like this? 37.5% is significant isn't it? I don't plan on doing anything till summer so plenty of time to work things out on paper.

    Just use the same level of expertise you used to come up with probably be lucky to get a +/- 50% guesstimate.

    DIY radiant heat system

    I've been looking for some tubing, (stainless is spendy) best I found so far is this. 1" OD 304/304L Stainless Steel Tubing, 16 Gauge (.065), Welded, A269, Mill ID, Bright Annealed would annealed effect the heat transfer? I can get enough for 6 18'' tubes for $50 what do you think? I really...

    OK, now were getting down to it! I had not thought of anything like that but it makes sense. Thanks

    DIY radiant heat system

    remove the door, block off the vent? Do you not understand I'm building a new box and the combustion area is sealed from the room? The photo of the oven was just to show how it was vented. I may use some of the parts but the oven is history. I have fans with PWM variable speed control, they are...

    DIY radiant heat system

    Thanks, I probably won't do this but would something like this I was playing around with a few ideas, trying to get the air to circulate a bit without using a fan.
