Single handle shower valves normally have some way of adjusting the "all the way hot" stop of the handle. In many cases it's just a toothed plastic ring under the handle that can be moved to the next tooth or two to make the water hotter. This is meant to be a safety feature so even if the handle is cranked all the way on you don't get scalding hot water. ...

There are special thermometers for refrigerator & freezer use. I have a Rubbermaid thermometer (amazon link) in my garage fridge compartment and another in its freezer. This showed me my freezer has trouble maintaining safe temperature during winter (unheated garage.)

For DIY you could use a RaspberryPi with a RaZberry (z-wave module for the Pi). RaZberry comes with a web-app and mobile apps. But you have to bring your controlling web-app into the net and care about the security! This way you can use standard z-wave products. In this case a radiator thermostat.

You may be able to use a propane or natural gas powered fridge. They have no moving parts that would break; in the extreme cold, I'd imagine that only the pilot light would be on. I've stayed in a cabin that had one of these that was regularly exposed to -25 F, and it lasted for 40+ years. http://home.howstuffworks.com/refrigerator5.htm

If you are on the cheap and can afford running wires there is a cheap & efficient solution : Rasperry Pi ( Appx $40 ) Dallas 1-wire DS18B20 sensors ( Appx $2.5 each ) Spare Wire The sensors can be connected to the Pi without requiring an external adapter, then you can run a Home Automation supervisor such as OpenHAB to monitor it and triggers various ...

The numbers are completely arbitrary, and are whatever the product manager or artist at the manufacturer decided they should be. They might be standardized within a company's product line. If these are private-label units, all bets are off. Numbers instead of real degrees means they used a thermostat too cheap to be consistent from unit to unit, so they ...

Elevating the conduit 7/8” or more off the roof surface will be more effective than painting but yes white is the least heat absorbing color. Why 7/8” elevation? That is what code requires or a temperature adder is used when derating the wire; with 7/8” elevation, the adder is not required. This is located in section 310.15(A)(3)(c), "Raceways and Cables ...

One example for an out-of-the-box solution is RWE Smarthome They have a special temperature package, but unfortunately their shop seems to be in German only. There is another solution by Devolo. Both of them use portal you connect to, and offer mobile apps to control your system. But I think there are many other producers/distributors.

Keep in mind what the pipes were made of and what they were full of. Copper is nearly the best conductor on earth, and the pipe was full of water, which is literally the best heat transfer fluid known to exist, and also convects, i.e. circulates freely. Iron is not as good a thermal conductor, the pipe will be much thicker, and natural gas is a fairly ...

OK Let me try. Originally you had your single zone heat on. My experience is first floors are usually warmer than second floors. Hot air wants to rise but it can't unless there's some cooler air replacing it. That's where the drafts come in from the older windows on the first and second floor. So heat rises to the second floor in addition to the second floor ...

That's easy. Thermostats don't work by duty cycle. They work by sensing the temperature in the room. The upstairs is cooler because the upstairs is now (let's say) 10% better insulated, but the furnace is running 20% less often. Why would it do that? Where's the thermostat?... Downstairs. Downstairs is in fact 20% better insulated, so the furnace ...

Put a box fan in the door, and let the central AC handle it.

Congratulations - you have eliminated all the ways this might actually work. Either deal with it being hotter, or add a few options that you say are "not an option" with the most logical one being a connection to the central A/C. With a bucket, you could go with 50 pounds of ice, a fan blowing over it and a bucket for it to drain into as it melts. That ...

Your best bet would be an IR or instant read thermometer. You should test it from the closest faucet to the hot water tank, and make sure to let it run for several minutes first. If you do use a leave-in meat thermometer, it might take several minutes to get an accurate reading. Ice water should be close to 0C/32F (and if you add salt, it would get even ...

Yes. One example is the Honeywell CT50K1028/E which is your basic low voltage thermostat it goes down to 35 F. I'm pretty sure it will work for your application. No hacking or electronics work reqired. There are others. Do a search for " Garage thermostat"

From GE Appliances Customer Service: There is no specific correlating temperature for each number setting. The TEMP control determines the compressor run time. The higher the number, the more the compressor will run to create a cooler room temperature.

Thermostat controls will always have some hysteresis between the ON detect temperature and the shut back off temperature. This is necessary so that the AC unit wouldn't be toggling on and off all the time at a rapid rate. More exact control is possible with a more expensive temperature control but that normally requires that the AC unit have an ability to ...

The washers are shipped with water in them. The reason is that, at the factory, they have to test them before shipping. Which means you hook them up and turn them on. Washing machines don't drain 100% of the water from the drum, so what you're hearing is the remainder of that test. In most cases, it's probably 1-2 gallons. The water doesn't hurt the machine(...

60/75°C Wire — All circuit breakers rated 125 A or less are marked for use with 60° C, 60/75°C or 75°C only wire. This marking indicates the proper wire size for termination in accordance with Table 310.15(B)(16) of the NEC . It is acceptable to use wire with a higher insulation rating if the ampacity is based on the wire temperature rating marked on the ...

There is no code against ventilating your closet into the other room. There are all kinds of crazy things I have seen to take a room that has great ventilation and move it to another room. If you go in the south of France you will see fans between the living space that has outdoor access in the connecting rooms. The only issue becomes if you had toxic ...

Look for an on/off switch or a heat/cool switch on the thermostat. If you can't turn it off, turn it to cool. If your thermostat doesn't have a switch like that, turn off the circuit breaker for the heater.

Place the bottom of the fabric in a shallow pan of water. It'll wick moisture continuously until the pan is empty. It should last a day at least, though. You could even suspend a wallpaper tray from the fabric itself, which you'd install on the curtain rod (assuming that it's robust enough). Place a rod through the ends of the tray with the curtain's hem ...

The general principle to use is that actual air leaks are a lot worse than just having poor insulation. Look around your doors, windows, plumbing, attic/basement/crawlspace access hatches, fireplace, and anywhere else where there's a hole in the wall. Anywhere you feel air movement is an issue. Anywhere you can see daylight (that's not glass) is an issue.

Thermostatic controllers typically become calcified over time. This can result in the temperature not setting properly when you adjust it or even vibration and/or knocking in the valve. Sometimes just turning the knob rapidly several times from stop to stop will loosen things up. The manufacturer also provides videos on cleaning the valve which you should ...

A variance of 50 degrees or more - both high & low - sounds extreme. However, a consistent offset of 25 to 50 degrees is actually not that unusual. Hypothetically, that could be 35 degrees miscalibration of the thermostat combined with a 15 degree temperature swing between cycles. I don't know what the typical temperature swing is for a residential oven. ...

It's likely that your switches have gone bad and need to be replaced. I had the same problem on a similar model last year. The way these switches work is with a bimetallic strip (similar to the way car turn signals used to work 25+ years ago). As the electric current travels through the strip, it heats the strip causing the metal to expand. Because the two ...

Such a variation is not normal unless you are using an abnormally high amount of water so that the water heater does not have enough time to recover. Otherwise, since the heater worked properly when first installed, I would recommend calling the installer.

Reportedly, it costs substantially more to pour a foundation because of additives and other precautions used to keep the concrete from freezing. This page lists extensive guidelines and recommendations from the American Concrete Institute. Never pour concrete on frozen ground, snow, or ice. Concrete in cold weather is recommended to have low slump, and ...

If it's too wet and water starts to accumulate in the foundation, you can end up with weakened concrete. One of the key metrics for a concrete mix is the free water to cement ratio. If the water content is too low, you struggle to get it to compact properly , resulting in air voids, and weak concrete. If the water content is too high, the water can leave ...
