A tankless water heater (also called instantaneous, continuous flow, inline or on-demand heaters) instantly heat water as it flows through the device. Where the traditional tank-style water heater held 30-50 gallons of water in reserve, the tankless water heater doesn't retain any water internally except for what is around the heat exchanger coil.

Some systems have a tankless heater in a central location (much like the traditional tank style), but most have more than one unit located close to the point of use (POU). A tankless heater might be located in the attic above the bathroom, in the shower itself, or under the kitchen sink. Their relatively small size (about the size of a briefcase) allows a lot of flexibility as to their location.

Tankless units can be split into two categories: "full on /full off&#34 or "modulated." As the name would suggest, a full-on/full-off unit doesn't have a variable output level; it's either on, or it isn't. Modulated tankless heaters base the heat output according to the flow of water running through the unit, modulating the gas valve and outlet so that the user receives the same temperature of water regardless of the flow.

Until recently, most tankless water heaters were electric, but newer models can run on natural gas or propane. Newer models can also deliver as much as 11 gallons of hot water per minute (such as the Noritz 841MC Series), which can meet any hot water needs. Everyone is familiar with the period of waiting for hot water from a conventional water heater, as the cold water in the lines must clear first before hot water comes through. With instantaneous heating from a Noritz tankless water heater, there's no wait for hot water (thereby saving on the water bill). Just one of many good reasons to buy a tankless water heater.

Noritz, in particular, has a dual flame design, with a second row of burners that burn the unburned gas that comes from the first row (all other competitors have a single-burner system). This means more efficient operation and fewer temperature fluctuations.

The heat exchanger of a water heater is perhaps its most critical element, as it is the component that is heated up to conduct heat to the water itself. After countless cycles of heating and cooling down, some heat exchangers can wind up with cracks or leaks. Noritz heat exchangers are made from copper piping that's 25%

thicker than most other brands. Commercial-grade components for residential applications; that's the Noritz design and quality advantage.

A trendy pastime among many of the aged as well as others is bird watching. Binoculars and a field guide are all you need for the delightful pastime, which makes it an inexpensive and enjoyable one for practically anyone.

There are over 10,000 species of different birds across the world. Aquatic birds, song birds, flightless birds, vibrantly colored birds, small birds, large birds; the varieties are practically innumerable. Watching birds should be done at a distance, since they are skittish and naturally cautious of human beings. This is why, for those who wish to become adept at bird watching, binoculars are a valuable and essential piece of equipment. 

There are many forms of binoculars available. Basic binoculars are generally the starting point for those who are just beginning as bird watchers. You should start with the cheaper or less expensive types and then upgrade to a pair with more advanced technology as your interest in bird watching increases. However, keep in mind that the best sightings will be made with a good pair. There are some guidelines that will help you to choose a pair of binoculars that will suit your needs.

Dimensions

Choose a pair of binoculars that will not be cumbersome to carry for hours at a time.  Especially once you have become hooked on finding and identifying our feathered friends, you will find that you will spend more and more time doing so.  If the binoculars are hefty and heavy, the weight may discourage you from indulging in a favorite pastime.

Magnification

Binoculars are identified by a set of numbers; i.e., “7 x 35”. The first number is the power, indicating in this example that something will be seen at 7 times closer than they actually are.  The second number is the diameter of the lens.  The larger the second number is, the more light will pass into the equipment and the easier it will be to see in dim lighting.  It will also make it easier to see birds that possess little to no bright colors.  

Focusing

As well as having great sightings at a distance, it is also important to have the ability to focus on objects within 20 feet of you so that you won’t lose an exciting sighting close up.

Undertaking a new hobby such as bird watching, binoculars and field guide in hand, may very well be the most enjoyable activity of your life.  With the appropriate equipment in hand at little expense, it can be as affordable as it is enjoyable.
