Furnaces
Modulating high furnace Is like highway driving, making slight operating adjustments while achieving maximum efficiency.
This new condensing furnace with a modulating gas valve operates with more finesse to reduce temperature fluctuations, providing consistent indoor temperature, quiet operation, and an annual fuel utilization efficiency (AFUE) of 98.2%.
Central Air conditioners: The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating of a unit, the more energy efficient it is.
Air conditioners with 14.5 seer rating and higher are eligible to receive government rebates.
Tankless Water Heaters heat water only when you need it. So you save money and reduce waste by not heating and reheating the same tank of water. Tankless water heaters are placed in-line like a conventional tank-style heater. However, it does not continuously heat a tank of water that is waiting to be used. When opening a hot water tap, or starting the dishwasher, the Rinnai tankless water heater recognizes the need for hot water and starts the heating process.
Humidifiers: Maintain your home’s most comfortable humidity level automatically with a Whole-house Humidifier. Proper humidity provides a more comfortable living environment at a lower temperature, so you can turn down your thermostat for energy savings.
Air Cleaners and purifiers have a drastic effect in the air quality of your home. In order to keep your house both warm during winter, and cold during summer, sealants make your house air-tight.
Full service Duct Cleaning encompasses the entire forced-air system, from each register and return down the duct lines to and including all main duct lines in the ceiling of the basement. Finally, the air handling side of the furnace is cleaned to remove any loose dirt and debris from around the air conditioning coils, exterior of heat exchanger, blower compartment and the plenum.
Heat recovery ventilator (HRV) can help make mechanical ventilation more cost effective by reclaiming energy from exhaust airflows. HRVs use heat exchangers to heat or cool incoming fresh air, recapturing 60 to 80 percent of the conditioned temperatures that would otherwise be lost.
Fireplaces are either direct vent or inserts.
Direct vent fireplaces are designed to be vented directly out the outside wall.
Inset fireplaces are designed to be inserted into an existing wood burning fireplace. A chimney liner is required to be installed with an insert fireplace.

Closed System in Chemistry: Definition & Example
This lesson provides a basic definition of a closed system from thermodynamics. Examples are included to provide students with illustrations of closed systems that are encountered within chemistry.
Definition of a Closed System
You have probably put soft drinks in a cooler under ice to keep them cold. When the lid of the cooler is closed, nothing can get in or out, and the insulated walls appear to keep all of the contents nice and frosty. However, if enough time passes, the ice does eventually melt into water. This is an excellent example of a closed system. What is a system, and, more to the point, what is a closed system? How are closed systems used in chemistry?
Cooler with iced soft drinks
The concept of a system comes from thermodynamics. a branch of physics that studies the transfer of energy between objects and their surroundings. A system within thermodynamics is defined as part of the physical universe. The system could be a car engine, a mass of air in the atmosphere, or even a soft drink can. Systems are separated from the rest of the physical universe (or the surroundings) by a boundary that can real (such as the walls of a cooler) or imaginary, used to focus on a specific part of a complicated situation, such as the combustion cylinder within an engine.
An engine with cylinders shown
Systems are classified in three basic ways: open, closed, or isolated. These describe how energy and matter are allowed to enter or leave the system. Within an open system. matter and energy freely cross the boundary of the system. For example, the Earth can be considered an open system because sunlight reaches the surface of our planet, meteorites can enter our atmosphere, and we can send objects out into space. Closed systems. like the closed cooler described previously, allow energy to cross the boundary of the system, but matter is prevented from being added to or removed from the system. Isolated systems allow neither matter nor energy to cross the boundary of the system.
The Earth, an open system
Examples of Closed Systems in Chemistry
Closed systems in chemistry are extremely useful for conducting chemical reactions, and rearranging atoms within matter to give new combinations of atoms. They are used in the laboratory as well as chemical industries such as the manufacture of medicines. The reactions occur in a special vessel known as a chemical reactor that has been sealed to prevent any matter from entering. The sealed reactor is now a closed system allowing for the careful control of the flow of energy across the walls of the reactor through heating or cooling.

ARDUINO WIRELESS HOME SECURITY SYSTEM: 11 Steps (with Pictures) #home #secuirty #system

ARDUINO WIRELESS HOME SECURITY SYSTEM
p hi there – your instructable is pretty amazing. I have a situation where I need a customized security system, and I m hoping this could be modified to do it. /p p I live in an apt, and whenever I go out, someone comes in and steals stuff. So far, my wallet, ID, banking info (which led to an ATM ripoff), and all kinds of personal items have been ripped. I have tried a cheap audio alarm, rekeying the locks, a code entry lock, but none of these have worked for me. /p p I have skimmed over your instructable, and from what I can see, it is the closest thing to what I need. I would like to put together something that would sense my door opening, take a picture of the offender (or a series of pictures), and email them (in real time, while it is happening) to me and to another mailbox. I would also like this proposed system to be inexpensive. Could this sytem do that. If not could you tell me where could I go to get what I need ? /p
Hi. br My question is can we transmitt two transmitter signals to only one reciver.
p Why did you not think to to generate an on_change interrupt on the rising or falling edges of the PIR? Would have made battery operation a heck of a lot more practical because most of the time your Arduino could be in deep sleep. Looping constantly polling for the pin is so 1970. Also, I imagine the transmitter doesn t use much power when it isn t actually transmitting but you could further reduce your battery drain by only switching it on whilst the Arduino is awake. A typical PIR might only use 50 micro;A so it would be fine but by removing the LEDs from the Arduino board and using the Lightweight low power library for Arduino. you can get the whole lot running on a couple cells for a good few months if not longer. /p p Nice idea but could be much better. Have you thought of having multiple transmitters? /p
p Hi, great project. br i like to ask u said that PIR motion sensor to detect the human motion right. what about animals like cat. /p
p I think no.But you can try with changing the antenna length. /p
p For what it s worth, I m doing my own window-shutter automation, and I ve also noticed that those cheap 433Mhz modules aren t suitable for a clear communication through concrete walls. I ve improved my system by using HC-12 modules (learned in this also great instructable: https://www.instructables.com/id/Long-Range-18km-Arduino-to-Arduino-Wireless-Commun/). They are a bit more expensive but much better with a suitable antenna than the cheap RF modules used before. Depending on the money you want to spend on this project, this could be another way to take this it to a higher RF level 😉 /p
p Yes and no. A simple RF amplifier would work. However if the RF power is more than 10mW you would need an amateur radio licence. I have such a licence so this is no problem for me. These transmitters are roughly 10mW so no, you cannot extend the range more than 100m. The longer the antenna does not mean the better the performance. The optimum antenna for this would be a 70cm long piece of wire. Any longer and you will reduce your range. Simply put, the higher gain your antenna is, the further distance the transmitter will transmit! /p
I want to add a little bit something in this project could you help me. I dont know what do add on it. Thanks
p have you got a link for the wire cutters/ the project enclosure? /p
p You can buy this wire cutter.Its a nice cutter. /p p a href= http://www.amazon.com/Hakko-CHP-170-Stand-off-Construction-21-Degree/dp/B00FZPDG1K?ie=UTF8 keywords=wire%20cutter qid=1465293960 ref_=sr_1_4 s=power-hand-tools sr=1-4 http://www.amazon.com/Hakko-CHP-170-Stand-off-Cons. /a /p p I purchased the enclosure from a local store. /p
p So, I am totally going to build this when my parts arrive, however, I have a feeling it is going to be completely useless due to the fact that the alarm is going to go off every day because of my cats. oh well. /p
p You are right 🙂 /p p You should think any other alternatives to avoid this problem. /p p Good luck. /p
p Hi everything is written here.I don t find any reason to send it to your mail.If you have any doubt, you can ask here. /p
For lower power consumption check this thread in the arduino forums http://forum.arduino.cc/index.php?topic=141759.15
p Thanks for giving the thread.Its useful. /p
