content: Hello,for some reason i really would like to know how cold/warm your lab/workshop is.Mine is about 3c at best with a bit of heating.Makes doing SMT stuff real fun combine this with a tea each second and you feel like chucking the board in the air.Stay safe.Alex.

content: My "lab" at this point is just a tiny desk in my computer room, I tend to keep it around 20-22C when I'm there. It's forced air for the whole house so basically if it's 22 in here it will be around 18 in the living room which is where the main sensor is. I let the living room drop to 12 when I'm not home or sleeping to save energy.I want to build a large desk to act as work bench and computer desk and wrap around the room but I need a place to build it in. My garage is too cold. (basically whatever it is outside since it's not insulated) so my next major home project is to insulate and finish the garage and bring in heat and turn it into a workshop, which could potentially double as a bigger lab depending how far I decide to dive into electronics. TBH I've been wanting to get more into electronics but it's hard without a proper work bench so I have to do a bunch of projects to lead up to that. First project was building a shed so I can move everything out of the garage so I can work on the garage. That's mostly done, so next step is garage. I have a lot of projects that are kind of a mix between wood working and electronics that depend on me having a proper heated work space so can't wait to have the garage done. Probably will be my main project next summer. There's some parts I might even be able to do in winter but anything involving concrete or sealants won't work as it gets like -30 in there.

If it was that cold in my lab, all I would need to have done was open the windows and it would've warmed up.To answer the question, at work the lab is heated to the low 20s. Today it's been mild outside and it was a bit too warm in the lab, so I've had the window open.At home I typically have the thermostat set to 15°C, but most rooms are a bit cooler than that. I prefer my house a little chilly, then I can wear a jumper to keep warm. If the house is warm, then it's fine when I'm sitting still, but if I want to do anything physical I feel too hot and start to sweat.

The door to the garden is open so the dogs can roam in and out, thus my office is 59F, 15C. Loving every minute of it. For the record, I am not wearing my usual shorts, t-shirt and sandals. I am wearing a polo shirt and long pants as I had service calls I needed to leave the house for. Sadly enough, the break in the temps is fleeting. Tomorrow back up to 78F and 80's over the weekend.

content: I don't like the temperature differentials of lab equipment being exposed to conditions much less then room temp and then being warmed up to running temp, you add like 30% to the operating range of the equipment, and the tempco curve kinda curves around room temp sometimes with some parts so i feel like its a bad idea. ewI read for instance over-cooling data centers actually decreases harddrive reliability for instance. Not sure if its just the mechanical bit but everything gets more stiff so you might have stress points develop that wont exist normally. Very stiff plastic at 0C compared to 20C.

content: My lab is in an unheated room at the end of a floor in a wooden house in Switzerland5-15°C in winter 20-30°C in summer. A bit cold in winter, a bit hot in summer.I keep my precision instruments in a heated room, so it doesn't really matter.Garage temperature does matter more, in winter it sometimes gets below 0°C. Oils get very viscous at these temperatures and you shouldn't use machines at these temperatures because of damage due to lack of lubrication. So not much (CNC) machining during winterThereby more electronics during winter, machine work in summer.

content: Quote from: InductorbackEMF on November 29, 2018, 02:00:18 amYeah it can get cold here. Typically December-March is our extreme cold but like not that long ago we did get -20. I find anything after -25 feels about the same: freaking cold! The biggest issue is the fingers really. You can dress for it, but to try to actually do anything in that you kind of need your hands. I don't envy cable splicers that have to work in those temps, or tower workers etc. It's hard to do that kind of work with gloves so probably end up taking them off half the time.Funny enough I can actually truly say that I walked up hill in -40's back when I was in school. It was only up hill one way though.The coldest I remember ever seeing is -49 without the windchill.So yeah, I can't wait to insulate and heat my garage so I can actually work on various projects in there. I want to experiment with using car radiators to basically move heat from the hose to the garage, without the need for an extra combustion appliance. It's more efficient to make the furnace work harder than to install a small heater, I figure. Most small heaters arn't condensing types. I'd probably try to only keep it at like 10-15 in there as it would be comfortable enough once I start moving around.

content: Quote from: cdev on November 29, 2018, 09:07:35 pmHeaters that use two pipes (intake and exhaust) are the best too as they don't create a vacuum, which will suck cold air back in and suck hot air out. Also these tend to be condensing which in itself is more efficient.Also lot of people tend to forget the importance of the vapour barrier - even builders. My house has a terrible vapour barrier installation as they didn't use tape, so it leaks like a sieve. I need to redo all the walls with new vapour barrier some time, but it's a messy job. Ideally you want a fully enclosed sealed envelope for the most efficient living space. For air freshness a HRV is the way to go to still have fresh air, without wasting heat or AC in summer. Funny enough my basement is hotter than the rest of the house because of the proper air sealing I did.

content: I have an HRV, its great.Even when its cold outside we still get fresh air and its not that cold.InductorbackEMF, you should be able to find some gloves with the ends of the fingers removed. If not buy some cheap stretch gloves made of some warm but thin material, chop off the ends of the fingers and darn them up with some spun thread using a big eyed needle. So you can do things requiring manual dexterity while your hands remain warm.You wouldn't believe how many great artists etc, have died or had their health seriously impacted because of chronic illnesses contracted by living or practicing too long in chilly garrets.Another scary problem which can be caused by cold, (but cold much warmer than frostbite, which is really bad cold) is primary Raynaud's phenomenon. Look it up.Also, in the UK lots of people get invasive fungal illnesses.Mold growing in the lungs or sinuses. Sometimes it spreads to the brain.When I was a kid I had a friend who had had something like that. Mucormycosis.But he didn't let it limit his life. This blind guy was probably one of the all time experts in identifying and controlling by means of his own voice, the ancient phone equipment that was around back then.Long before the Internet even existed.

content: Interestingly, though (slightly) off topic as I don't have a 'Lab' now per-say, 'temperature' can be a funnything, in a work-environment. One of my professional specialties was designing/maintaining electronic &computerized energy management and HVAC systems in high-rise buildings. (Damn, this is going to snowball!).Firstly, Engineers always rely on the 'fact' that workers in a COLDER environment are more PRODUCTIVE !!Secondly, that 'science' has proven that our PERCEPTION of temperatures varies greatly, depending on thecurrent season, and relative to the outside temperature. For instance (here in Australia!!) if it is say 37-Coutside, then people will feel quite comfortable inside, if it's say 28-C there. Likewise if it is say 12-C outsidethen people inside feel comfortable at say 19 to 20-C. This results in MASSIVE energy/power savings for thePlants in such large buildings. (I'm talking about $100,000 to $250,000 savings per year!! )...MOST large 'plants' have what they call the 'Z.E.B.' (Zero Energy Band). They have huge Boilers, and hugeChiller-Plants, that rely on 'smart' heating/cooling calls from numerous zones/floors before starting up.You can't have ONE sensor from ONE floor with a 'toaster' under it, causing a huge building-chiller to run !!(Now try to explain that to building customers !!!! )Now it gets HARD !!!!Some buildings are solely owner/occupier and are interested in energy savings... (no shit!!)However, a LOT of them have NUMEROUS companies that they rent out floors to, and they charge themfor the power they use also, and are NOT interested in any energy savings !! (Enough for now... :-) )

My basement is warmer than the rest of the house because it's better insulated. I could make a pretty nice lab down there. Hmmm.

So we will see how well they work, one will likely be sacrificed for science to see how safe it is(Its a chinese product after all).

content: 7 degrees at the moment. My lab is just bit of roof attached to te back of house. Means no wall on one side and exposed to elements. 5-10 degrees is still ok for me, long johns and couple of hoodies do the job. Less than 5 your hands start to get cold/freeze means no much manual work possible.

content: I find hands are the issue with working in the cold. It's hard to do anything with gloves on. I built my shed last year in the cold, and it was kinda miserable, but better than doing it months before when all it did is rain. Once you get moving the hands arn't actually that bad, but in the -30's it's cold no matter what.I guess with electronics you could mount a heater just pointing at your work area to keep your hands warm. Maybe at a slight angle so it's not blowing solder fumes in your face.

content: Well i thought i just posted this but forgot the puny size limit for photos and now im back to square 1.Anyway so we had a warmish morning after a cold night so i thought to check if it was infact staying cold and not warming up in the day.Looks like you was right haha.Sorry about having to use a photo hosting website but can not use my photos on this forum due to size.https://imgur.com/a/q1y0PSIAlex.Ps i will try all the ideas you guys have.I may try and cover some of the walls with Thick foam to see if it helps anyhow.

content: Quote from: InductorbackEMF on November 29, 2018, 01:15:29 amYour question contains an implicit fault: Acoldroom can NEVER be called a 'Lab'!A relatively constant temperature is needed.Therefore, you have no lab, but sort of a climate chamber, instead.My basement lab has about 21°C, ranging from 20 to 24°C, depending a bit on the seasons.In winter, the room is heated, and in really hot summers, like the last one with nearly 40°C outside, interior temperature rises a few degrees only, because our house is very well isolated. See temperature log:When making sensitive analogue measurements, the lab temperature typically is constant within a few tenths of a °C, over several days.But I have to keep disturbance factors out, like my wife.Frank

content: Around a year ago I got a digital hot plate for preheating solder work. It works well.But, it also makes a damn good heater when set to quite modest temperatures. And it could run forever at such low temps. It wasn't that expensive, it cost me around $45 US on ebay. That was an unusually low price, many other sellers had it for more. Its blue has a digital readout, is made for things like that, and it is unbranded.It can also be used to do reflow.
