Tankless Hot Water Heater - How Can It Improve Your Home

How often did you take a shower and the water started to run cold before you were finished? Don't you hate that? With a traditional water heater this is always a problem. And if another person wants to use hot water after you, just forget it! Buying a water heater with a bigger tank might solve the problem, but it is expensive, it is huge and eventually any size heater can run out of water. Is there another way? Yes, you can switch to a tankless hot water heater that heats water as you need it.

How does a tankless hot water heater work?

There are two ways to heat water. One is to store it in a tank and heat it up there; this is what conventional heaters do. Another way is to heat water as it passes through the pipes -tankless heaters work this way.

Tankless Water Heater Pros

Tankless heaters have four advantages:

• provides hot water instantly and for as long as you need it
• uses less energy
• lasts for a long time
• much smaller than a ordinary water heater

The best thing about a tankless hot water heater is that it heats up water as you use it. So you don't have to wait while it fills the tank and heats up. Hot waves heat up water as it passes through the pipes. So it doesn't need to be stored anywhere prior to heating. What it means for you is that using a tankless electric heater you will never run out of hot water while in the shower. And if several members of your family take a shower one after another, a tankless hot water heater is a great time saver because you don't have to wait the tank to refill.

How can a tankless heater help you save energy? Other water systems heat water all the time, even if you are not using it. Tankless heater, on the other hand, only heats water on demand. It doesnt waste energy heating up water while you are at work or on holidays.

The amount of savings depends on how much water you generally use. If you consume a lot and need it all day, than the savings will not be as great. But if you use hot water only in the morning and in the evening, like most full time working people do, your energy bill will go down substantially.

Another advantage is that tankless heaters have a longer life span those ordinary heaters. The reason is that water is heated as it passes through, so there are no mineral build ups. If you purchase a tankless heater by a good brand such as Bosch, Kenmore or American Water Heater, it can last as long as 20 years without being repaired or replaced.

Also tankless water heaters are much smaller than the conventional ones. So if the space is an issue, tankless heater will be great for a small home or apartment.

Tankless Electric Hot Water Heater Cons

Nothing in this world is perfect and where there are pros, there are cons as well. And for tankless hot water heaters it is the initial cost. Tankless heaters are much more expensive than ordinary water heating systems. However, if you invest in a high quality tankless heater, it will save you in energy savings in a long term.

How Tankless Water Heaters are used?

Tankless heaters are suitable for use in residential homes as well as commercial places. It can be used in swimming pools, one-day laundries, nursing homes and hospitals.

Most heaters have a thermostat that allows you adjust the temperature. You can set it on low if you have small children in the house to protect them from burning themselves. On the other hand, if you want instant hot shower, setting the temperature to high is recommended.

If you are tired of your current water heater consider a tankless water heater instead. It is very convenient, and its high price is overweighed by the benefits.

How to Troubleshoot Video Problems

Few things can be as frustrating as picture problems. You get your system all ready to go, flip the switch, and WHAM! One or more channels look terrible. The good news is that the majority of video problems can be traced to just a few causes. Most problems are comprised of the following:

Snow

Horizontal bars rolling though the picture

Vertical bars rolling through the picture

Ghosting

Herringbone pattern (diagonal lines through picture)

Lower channels look fine, upper channels are not

These six are the main symptoms youll find when seeing video problems. Thankfully, most are fairly easy to fix.

Snow -

Snow is caused by inadequate signal strength at the tuner. Its usually caused by:

1Splitting the signal too many times.

2A weak signal from the antenna or cable company

3A very long cable run

If the signal is snowy at all your tvs, especially if you have more than 4 tvs, you probably need an RF amplifier. Check the strength at the demark (service entrance). If it is fine there, add an amplifier before the splitter. Make sure to use a quality unit with good bandwidth (out to at least 1000MHz). If you have digital cable or a cable modem, get an amplifier with a bidirectional return path to allow for communication back to the cable company. If the picture looks bad at the demark, contact the cable company.

If it is bad at only one TV, you may have a bad cable between the splitter and the TV or a very long run of cable. You can amplify just that run.

Horizontal Rolling Bars

Horizontal rolling bars are caused by DC power getting into the cable system. To fix it, disconnect the TV from all other components in the system. If the bars disappear, add the other components back in until the bars return. When you find the offending component, use a DC blocker to eliminate the DC power path to the system.

Vertical Rolling Bars

Vertical rolling bars are caused by AC power getting on the cable line. The best fix for this is to use a ground breaker. A ground breaker eliminates the electrical connection between the TV and the cable system. A ground breaker is also the main fix for a hum on your audio systems speakers.

Ghosting

Ghosting is caused by the tuner receiving identical signals at slightly different times. It can be caused by your TV receiving a local station broadcasting over the air and via the cable system at the same time. Make sure you are using good quality RG-6 coax cable and good compression fittings. Replace any low quality cable splitters or combiners with high quality units. Make sure they are tight also. This will also cure another cause of ghosting, signal reflection inside a poor cable.

Ghosting can also be caused by multi-path interference on an antenna system. This is especially true in an urban environment with lots of hills and tall buildings. To combat this, use a very directional antenna aimed directly at the desired station.

Herringbone Pattern

A herringbone pattern is caused by radio frequency interference from other stations transmitting on the same channel or adjacent channels, powerful radio signals, computers, etc. Another common cause is being equidistant from two transmitters operating on the same channel.

In short, this can be caused by just about any sort of RF radiation at the correct frequency. Really great shielding found on high quality cables helps to combat this. If you are getting this interference while modulating an A/V source on a certain channel, try switching to a different channel.

Poor Upper Channel Reception

Poor Upper Channel Reception is caused by poor signal strength on the upper channels. Use an amplifier with a tilt compensator that allows adjustment of the upper channels relative to the lower channels. This will prevent overdriving the lower channels while providing the upper channels with enough gain. Also, check to see if all components in the RF system are rated to at least 1GHz and RG-6 or RG-6Quad shield cable is being used throughout.
