    Deadband/Differential WiFi Thermostat

    Gosh....now you guys have gotten me thinking I need to replace t-stats in my house. I bought state-of-the-art units, but that was over 15 years ago. Question: Is there any modern thermostat that will still allow the furnace to function if the battery goes dead? (I think I know the answer...

    Start 'em young!

    Found this 2006 pic when searching old emails this morning. I believe I sent my two oldest boys out to the garage build to put together a drawing on the hydronic loops with measurements back to the walls for future reference. I think they picked up the floor drains too, and drew in the...

    Radiant floor using existing oil furnace

    I'm glad MongoTA was able to make his underfloor radiant work and good luck to the OP as well. When I did my garage addition I put radiant in the floor and also used PEX loops under the floor above (bonus room) as zone 2 and PEX loops in the breezeway that we built to tie the new garage to the...

    "New" refrigerant - R290

    I've got an old natural gas servel in my barn. The only power it uses is to run the light bulb when you open the door. I'm guessing it is about 75 years old and works as new when I light it. I don't use it all the time as they are considered dangerous/banned/recalled due to issues with...

    Home Built 24-inch Drum Sander made out of scraps.

    Hey guys, A couple of months ago I was playing around with some apple logs trimmed out of our trees. I band sawed out some small sections with the end grain showing, thinking I’d glue it up into a cutting board. Well, basically my planer was not able to handle the boards. I really needed a...

    Cutting a Propane Tank - Best Gas Detector?

    The best thing I've found for mercaptan odor removal is the scented bio-spray that has mercaptan ingesting bacteria in it. The bacteria will eat about any petrochemical including mercaptan. However, as noted above, mercaptan is highly flammable itself. It has to be, or you'd smell it...

    My father's workbench

    I think those tiles are leftovers from a kitchen remodel Mom had done about 10 years ago. If so, they might be useful if a tile got cracked. If not, they need to go to the curb too. I'll have to look at the kitchen and see.

    My father's workbench

    Saturday my wife and I made the 30 minute drive to my Mom's house. My boyhood home we moved into when I was 6. It was locked up tight. Mom moved to a nearby town to live with my brother when she couldn't live on her own anymore. She had a house sitter (AKA renter who didn't pay rent)...

    OEM O2 Sensor Wrench

    Sweet. The style OP post may work great for him, as he says he's replaced the sensors before. However, that style pictured that has the split in it was a bear for me to use on my 10 year old Tacoma that had never had the sensor removed. Your torque is severely limited by the split-type...

    Drum Sander Dust Collection using a shop vac? Possible?

    That was what I feared. Probably better off just keeping the shop vac handy and using it to **** the dust out of my hair and off my safety glasses.

    Drum Sander Dust Collection using a shop vac? Possible?

    Hey guys, I'll post up this whole project when complete, but basically what I have done is scratch build a 24-inch drum sander. It works and will sand boards. My next step is to use it to sand an actual project. I was thinking I'd build a cutting board using oak and walnut strips glued...

    Kentucky garage insulation/heating

    Man, I know you can find cheaper, but I've not found anyone more professional than Graber Post...if you're thinking about pole type construction. They've done a couple of commercial expansion projects for us at my workplace. They handled all the state required permitting no issues. When the...

    Honeywell Gas Control Valve (Water Heater)

    If you're talking about hot water in the summer...a couple of things. The pilot puts out (say) 600 BTU's per hour. That's not a lot, but if there's no water being used, my pilot keeps my water heater pretty hot all the time. As far as the control knob for Temp on an AO Smith Water heater...

    What's the good 1500w garage heater?

    OP asks if there are "any good ones". I'm going to say "NO". They are all energy hogs that use 3 to 5 times as much electricity as a mini-split would to create the same heating effect. Four of them (6KW) sounds like a lot of heat, but is only equal to a 20,472 BTU/hour. For...

    Running gas heat

    Agree with American Locomotive above with one exception. First the agreement: Heat transfer out of a building is dependent upon the temperature differential inside the building and outside the building. If you setback the t-stat, now there is less difference between those 2 temps. Less...

    Heating a large garage .... need real world advice please

    I'm thinking natural gas hanging heater all day for your situation based on: 1. NG is available 2. You only want to heat minimally with the ability to bring the temperature up to a more comfortable level perhaps when you are working out there. That just screams NG hanging heater to me and...

    Boiler shed?

    I'm curious about your supply of waste oil. Is this a "sure thing" you can get as needed? Problem would be if you spent thousands on this and then your supply dried up.

    Finding Conduit sandwiched between flooring?

    I'm confused. Is the conduit steel? Cause if it's plastic a magnet isn't going to find it and it certainly won't find the copper conductor either. Also...you can rent this: https://www.transcat.com/rental-equipment/electrical-instrument/cable-locator-rental/amprobe-at-2005-a-for-rent

    using galvanized pipe for air lines

    2" type L copper is more than $15 per foot around here. Not saying it's not better...just saying. I plumbed mine in black iron in 2010. No issues to this point with the iron. I have had to replace the rubber lines on my hose reels.

    Take advantage of natural gas line or go electric?

    The OPs cost per therm appears to be flawed. My WAG is he took a summer bill, including customer charge, and divided the $ by therms and got 3. I'm not even saying that's "wrong", but if he already has gas, the correct way would be to subtract the monthly customer charge and divide the...
