The Interplay Of Humidity Air Conditioner, And Heater

The term humidity refers to the vaporized water existent in the air surrounding us. We commonly hear of relative humidity i.e. the percentage of water vapor measured in the air at a specific temperature. Absolute humidity is the total mass of water vapor in particular volume of air at a given time. It is a well-understood fact that warm air can hold greater quantity of water vapor than cold air. Since air conditioner and heater both alter the air temperature, the humidity level indoors changes significantly with their use.

Humidity Levels And Comfort

The relative humidity level for comfortable condition of the human body is between 20 and 60 percent. For home environment an average 35 to 40 percent relative humidity is optimum given an outside temperature of 20°F or more. But during winter, water vapors on windows and inside of walls occur, raising the humidity level inside. This may cause damage to the structures. In such a case, you need to adjust both your air conditioner and heater to lower degrees. The air conditioner lowers the temperature, which induces condensation on the inner sides of windowpanes. A heater, on the other hand, speeds up the process of evaporation from moisture contained in household items. However, running a patio heater in times of higher humidity inside can counter the problem to some degrees. With air conditioner and heater units, using a humidifier is the best option.

The most obvious signs of discomfort caused by low humidity levels indoors are dry nose and throat, itching, dryness of skin and hair, and irritation of the respiratory tract. To increase the humidity level, instead of an air conditioner and heater, you can use a humidifier. The increase can be brought about in three ways. First, by evaporating more water inside. Here you can use your heater to speed up the process. Take care not to set the heating level too high or you can possibly harm both your health and the indoor plants. The second way is to let air circulate through your room from a wet pad or by discharging a very fine mist of water into your room. For this, you have to add water manually on a regular basis until the desired level of comfort is attained. The third method employs direct introduction of moisture into the room, by means of a furnace.

While using air conditioner and heater for regulating temperature indoor, always use a humidity control unit so as to prevent the levels of humidity from going too high or too low and cause possible health problems as well as structural damage.

Swimming Pool Heater Adds To Enjoyment

Nobody enjoys swimming in cold water, which is why most people installing a pool opt for a swimming pool heater to keep the temperature more comfortable. Several options exist, including gas, heat-pump and solar power. Which option is chosen by the pool owner will be determined by their budget.

Understand, most swimming pool heaters operate on the same premise. Water is pumped from the swimming pool, through the heater and back into the pool where the heated water raises the temperature level of the pool water. A thermostat installed on the line into the pump records the temperature of the water in the pool and stops pumping until the temperature drops below a pre-set temperature.

How the water is heated is what determines the cost. There are two variables to consider when deciding the type of swimming pool heater is best for your pool. The initial cost and the annual operating cost. Some may offer cheaper installation costs, but prices of utilities and the climate in the area, may make them expensive to operate during the season.

Installation And Operating Expenses

Of the three main types of swimming pool heater, gas, either natural or propane, is the cheapest for initial installation. For comparison purposes an example of a 15 foot by 30 foot kidney shaped pool will be used. A gas swimming pool heater will cost roughly $1,200 and another $500 for installation. A homeowner can usually install a swimming pool heater themself, but it is highly recommended that connections for gas and electric be left to a licensed professional.

A heat pump swimming pool heater is more expensive to install, about $3,900 including installation and a solar powered swimming pool heater will run about $3,000 with installation. Their operating costs are what sets them apart.

A gas swimming pool heater will cost about $1.20 to realize a dollar’s worth of heat. On an average, it’s expected to cost between $1,000 and $1,500 per season to operate on propane. Depending on the price of natural gas in the area, it could cost about 50 percent less.

A heat pump swimming pool heater, on the other hand will cost about 20 cents for $1,00 worth of heat, bringing the annual cost of between $250 to $500 per year, which can offset the initial cost. A solar powered swimming pool heater will cost about $30 to $75 in electric to operate the pump required for water circulation, but not for the power itself.

Solar Heaters: Wave Of The Future

Solar heat, or energy, is radiation produced by nuclear fission deep within the sun’s core. Solar heat travels to Earth through space via photons, or “packets” of energy. Our Earth’s atmosphere and clouds absorb much of this heat, and the energy varies with the time of day and the season. 1.4 kilowatts per square meter is considered to be the “solar constant;” any substantial change in this wattage would alter or even end life on Earth.

We can make good use of the solar heat that we collect. Primarily, we can tap into solar power stored in water by directing the flowing water through turbines, thus creating hydroelectric power. Since plants are living solar heaters via the process of photosynthesis, we can use a plant’s stored solar energy through natural fuels such as wood, alcohol and methane.

How Do Solar Heaters Work?

To make solar energy work for us, we’ve devised two ways of capturing and using this source of power. “Flat plate collectors” and “concentrating collectors” need large surfaces exposed to the sun to create solar heaters of any purpose. For example, to use the sun’s energy to power a home solar heater for one day requires a collector surface as big as a two-car garage.

Flat plate collectors are just that: flat, thin boxes with transparent covers that are mounted on rooftops facing the sun. To empower solar heaters, the sun’s heat absorbs into the plate and heats either air or water in tubes running within the collector. This type of solar heater is an excellent, predictable way of heating water or a structure, where collectors are concentrated in the roof.

For many industrial heat requirements, flat plate collectors aren’t sufficient. Concentrating collectors in large areas provide much more efficient solar heaters. These collectors actually move to follow the sun, unlike fixed flat plate collectors. They also power solar heaters by using curved mirrors with aluminum or silver reflecting surfaces that gather much more of the sun’s energy than flat plates.

The future of solar heaters is exciting indeed! As we grow more proficient in using the sun as an energy source, we could eliminate the need for gasoline-powered automobiles. We could also generate solar heaters on a large scale. As solar science progresses, we will see government, industry and utility companies forming partnerships to reduce the cost of solar collectors. Imagine: a world without reliance on oil. Peace at last?

Portable Heater – Boon Or Curse?

Imagine planning out a wonderful vacation out in the mountains and finding out that the water is ice cold while wanting to take bath. The whole day you would be miserable afterwards. Then, imagine the availability of a portable water heater. Ah! All your problems solved with one phrase.

There Are More Portable Heaters Than This

Portable water heaters are not the only ones that can be carried along for providing home-like comfort in camps in the mountains. You will also need a plain portable heater if you are sleeping somewhere in the wilderness. This is for two reasons – animals are attracted to the smell of man, and will come and investigate whenever they get it. However, they are averse to any type of fire, and fire-related things. A portable heater would he of great help to send off wild animals of nothing else.

We have reports though that sometimes the animals have been attracted because people were carrying portable heaters and these provided them with some warmth when they were feeling cold. Hence, utmost precaution should be taken when going to mountain camps, particularly when the climate is not very conducive.

Some other types of portable heaters are patio heaters which are built with open spaces in mind, and gas portable water heaters. In both the cases the heaters are tested and put through a number of rigorous hand-on use. After one month of rough usage, if the heater is still working fine, then it will be promoted in the market.

However, even then there are instances when among all these tested ones, one un-checked slipped; and as luck would have it, that particular one will be the one that would go to the most spirited customer who would fight anyone to get compensation and all from the irate customer.

It takes a lot to placate an irate customer- but the best policy till date is to accept the complaints looking chastised and then proceed in charming her/his off their feet. This part will be easy because all people are ego conscious and love a little flattery. If you can manage the right balance then the day would end in good news. Otherwise, we have lost a passenger.

Hence, for this product too, there should be a better customer-placating bias. Then, please cut out into our work. The portable heater is indeed a boon to mankind, provided it works well and does not malfunction.

Outdoor Heaters: A Portal Back Through Time

There’s something about fire, something mystical that we’re instinctively drawn to despite the modern conveniences of our time. Today we live in a world where our cell phones take pictures, play music, and write messages. Our television sets get 165 stations. Everything we want to eat is ten minutes away at the grocery store or the drive-through. Our clothes don’t fade or wrinkle, our pets have medical insurance, and we can play movies in our automobiles.

But stoke up a nice fire, and we’re suddenly transported back in time, to the days when early mankind huddled around open fires for warmth, to prepare food, and protection from enemies – both human and animals. Outdoor heaters are a representation of our still-strong instincts to regard fire as life-giving and security in a dangerous world. Fireplaces and woodstoves in our homes are now commonplace, but outdoor heaters remain remnants of eons past.

How To Shop For An Outdoor Heater

To make the magic of an outdoor heater work for you, your first step is to decide what kind of heater you want and can afford. Most merchants who deal in these heaters have displays in their stores of the different types of outdoor heaters available. Do you prefer an in-ground heater similar to a fire pit? Or would you prefer a stand-alone heater that you can place anywhere in your yard or on your patio? Stand-alone heaters are as much decorative as they are practical. Not only will these outdoor heaters provide warmth and soothing serenity, they also serve as delightful decorative accessories to your home and yard. Round, square, pot-bellied, cactus-shaped – all are serviceable and attractive. They have a wide, open “mouth” or fire-area where you put the fuel, plus a venting hole on top to prevent smoke from choking you, your family and your guests.

Next, consider what type of fuel you want to burn in your outdoor heater. Cut cordwood is the perennial favorite, possibly because of its connection to our ancestral past. Firewood burns hot and creates a lot of smoke. Some prefer to burn charcoal, and still others prefer the new smokeless pellets that provide warmth and a “clean” burn. Firewood is the least expensive fuel for your outdoor heater, with pellets being the most expensive. If you’re uncertain, you can try each type of fuel and decide which you prefer and which you can easiest afford.

Regardless of the style of outdoor heater you buy, that ancient instinct will emerge as you slide closer to the flames. Sooner or later, someone’s going to stick a hot dog into the heater, you can count on it!

The Advantages Of Hot Water Gas Heaters

There are many ways to heat water. Among the more popular heaters you will definitely find the hot water gas heaters. These heaters are able to make the water at a high concession from he regular cost. There are far more advanced technology today and many of it logically have replaced he requirements of using the hot water gas heater. However, people all over the world still cling to this method of heating water stoically. Why? What do the people gain so much out of it that they need to stop the advancement of technology?

There Are Many Types Of Other Heaters Besides The Hot Water Gas Heater

There are indeed a good number of other heaters available and there are a lot people who are happy that such appliances have at last come out, so they would be able to enjoy the benefits that the modern technology brings. The electric water heater, for example, is in high demand and people are highly satisfied with their use. However, if you look at it, from a metaphorical point of view, the old is still gold, and the annual sale of hot water gas heaters were more than the other types, thought the other types are considered are considered far superior in performance.

The newest addition of the market is the tank less water heaters which are exceptional when it comes to work. They provide hot water the moment you turn the tap on, no exceptions. This is very much appreciated by young college girls because now they can take bath anytime of the evening or morning without having to worry of switching on the geyser 20-30 minutes ahead of time.

The choice of people in general, nonetheless, stays loyal to the hot water gas heater because it is simple to use and hence, its technology is understood by all without any exceptions. Second, it is much, much cheaper than the other modern heaters, which makes the hot water gas heater an all-rounder.

There are a few disadvantages though – the hot water gas heater is a but slow when compared to the other types of heaters and it also offers you almost always the cheapest possible price for hot water. On the other hand, the moment you need it to cool down, it can do so in the minimum of time, since the gas can immediately manipulated, giving you the exact ecstatic feeling of being able to soak into the tub at the exact temperature you love.

Selecting And Maintaining A Gas Water Heater

We’ve all been there; you’re having overnight guests, including your special gourmet dinner meal. It’s seven o’clock, and the doorbell rings. They’re here! Time for you to shine.

The unforeseen and unthinkable happens; you start washing dishes as your guests settle into their accommodations. You expect plenty of hot water for dishwashing and evening bathing by your guests, but the faucet spews only cool water. Panic sets in; what happened?

To your dismay, you find that your gas water heater has died a sudden, inconvenient death. The repairman, whom you are paying overtime, gives you the bad news; your gas water heater won’t hold a pilot light. He can’t fix it; it must be replaced. No, he can’t do it tonight; your guests are stuck with cold showers.

Choosing And Maintaining The Right Gas Water Heater

The above social nightmare is actually a rare occurrence. Gas water heaters are generally durable and easy to service and maintain. Depending on the brand, they can last for up to fifteen years, trouble-free. Using clean-burning natural gas as fuel, gas water heaters rarely lose their pilot light. Even when they do, re-lighting the pilot is often a simple job completed in five minutes. Just follow the instructions located in the customer’s manual. If the pilot won’t re-light, then it’s time to call a service technician; something’s amiss that you can’t fix on your own.

Before you choose a gas water heater, carefully consider your hot water consumption needs. The amount of hot water needed by a couple is far less than that required by a family of five. However, couples who plan to eventually have children should take this into consideration; what serves them well now – a twenty-gallon capacity gas water heater – will change considerably when the children arrive! Parents with several children will reduce their hot water needs when the children eventually leave home. Marketers of gas water heaters generally recommend a capacity of 50-70 gallons; it’s better to have more than you need than less than you need. Heaters with this capacity usually cost between $300 – $700, depending upon the brand and the service contract.

It’s recommended that you purchase a warranty for the life of the gas water heater. Although these appliances are exceptionally durable, there’s always the possibility that yours will “go down.” Without a warranty, it’s probably most financially feasible to buy a new gas water heater. If yours is covered by a service or replacement warranty, you’ll fare much better financially.

Enjoy An Electric Pool Heater

A swimming pool, whether in ground or above ground, is a big investment. You probably made that investment because you enjoy the pool so much. It’s hard to wait through the nearly warm spring to start using the pool and it’s heartbreak to start packing up the swim gear so early in the fall. One good way to get more from your investment is to install an electric pool heater. Just by increasing the pool’s warmth a few degrees, you can extend swimming season and add hours to every swimming day.

Safe And Efficient

If you don’t have an electric pool heater, you’re probably using solar energy. In other words, you sit around the pool waiting for the sun to warm up the water. With an electric pool heater, you get to decide when the swimming starts. Use the thermostat to keep the water at your preferred temperature. If you like a morning swim, you can get an electric pool heater with a timer to start the warming in time for your early laps. If swimming is an activity you prefer to enjoy after lunch, the time and thermostat save energy in the morning and ensure the best temperature when you are ready to enjoy it. And if you like to watch the sunset in the pool, the thermostat will keep the water as warm as you like well into the night as you wish.

Once the electric pool heater is professionally – and safely – installed, you can decide how to use it. Many heaters use the ambient air to warm the water, using energy to disperse the existing heat rather than creating it. You can save energy by using a solar pool cover to keep the heat in the pool over night. The cover will also keep the cold rain water out. It can take an hour of energy to heat the pool up one degree. Look for corrosive-free metal parts like copper and bronze rather than aluminum. Chlorine can be harmful to some metals. Some types of electric pool heater can double as a spa heater. If you have a spa or hot tub or are thinking of adding one, you might want to look into the versatile type of electric pool heater to avoid having to buy a second heater.

When making your selection, make sure that you choose an electric pool heater that is appropriate for the size of your swimming pool. Have your dealer explain how to install and maintain your heater. Be sure that you understand all of the safety requirements. Water and electricity are not naturally friends. Once you know what to do and how to do it, your biggest job will be to enjoy your pool while your neighbors are still waiting for the morning chill to dissipate.

The Tankless Electric Hot Water Heater – A Great Device

Science does not allow any stagnation of technology. Water heaters, too, have come a long way from the coal and wood consumption types to today’s exceptional types of modern water heaters. One among the most convenient ones is the tankless electric hot water heater. If you are wondering what it is meant by ‘tankless’, let me enlighten you. There are two types of heaters. One is the heater which heats the water after it descends into a tank prescribed for this purpose, and the other one is one which will provide you with hot water without having to store water anywhere prior to the heating.

The Advantages Of The Tankless Electric Hot Water Heater

The main advantage is all the time you’ll save. The tankless electric hot water heater is a exceptional device by which water gets heated through hot waves, which pass through the pipes directly. It does not need to be stored in a place for heating up. This saves a lot of time; hence, it reduces anxiety regarding hot water and other related issues.

You will find the best of technology used in the making of the tankless electric hot water heaters of today. The features of the device are such that the tankless electric hot water heater can be applied to both residence and commercial places without any inconvenience, or major makeovers. This means that the cost would be more or less the same for both places.

The most common uses for this type of technology are swimming pools, one-day laundries, hospitals, nursing homes, and so on. Most of them come with a thermostat which can be used to fix the temperature. If it goes below three degrees, it will send its ‘control’ a message and then you will receive an immediate respite, or tuning up, of the heat. In many cases, the oscillation of the heat is controlled automatically, once you have fed the minimum and maximum ranges into its controlling device/remote.

The Disadvantages Of The Tankless Water Heater

Every good thing has a minus side and a plus side. You have read all the plus sides. Aren’t you interested to learn about the downside of this technological aspect? Well, the first and foremost is the cost. The electric hot water heater is far more expensive than the other types of heaters. This is because it needs a great deal of power to keep the water at a constant level of heat. If the minimum and maximum vary greatly, then it could be possible to cut cost a bit, since it will switch off automatically a little longer.

Gas Heater For Above Ground Pool

Swimming in a pool is a joyful act but only if the temperature of the pool water remains in a narrow range i.e. 25 to 26 Celsius degrees. This temperature is not easily maintained naturally. During the swimming season the temperature of an above ground pool is in the range of 18 to 20 Celsius degrees, lower than that required for leisure swimming. In the morning, the pool water is rather cold due to loss of heat during the night. Hence we need a heater for above ground pool. Such a heater may be run by a variety of energy sources e.g. combustible gas, oil, or electricity (in which case the heater is commonly called heat pump).

Why Choose A Gas Heater For Above Ground Pool

A gas heater is the most popular source of heating the water of an above ground pool. This is because heating the pool by a gas is quicker and more efficient than by other means. Easy availability of natural gas and propane give an added advantage to gas heaters over other kinds. This makes both home and spa owners go for a gas heater for above ground pool.

Working Of A Gas Heater For Above Ground Pool

In a typical gas heater, the pool water flows through a port and gains heat from a heat exchanger. Then it comes out through a second port and falls back into the pool. In most heaters, the just-heated water is mixed with cool water resulting in maintaining a preset temperature.

Size And Sizing Of A Gas Heater For The Pool

The size of a gas heater for above ground pool depends on the size of the pool; larger heaters for bigger pools and vice versa. Also, if the difference between the pool’s temperature and that which you desire is large, you will need a larger heater even for a small pool. Further, if you can wait for your pool to get warm, a small heater may do well for an average size pool. But if you need a quick heating up of the pool, a larger size heater will be required.

Sizing refers to the ratio of input rating (the amount of fuel energy consumed), measured in Mega Joules or MJ, and energy output rating (amount of heat energy evolved), measured in Kilowatts or KW. A gas heater in the range of 60 to 100 MJ is considered a small one while a heater from 250 up to 400 MJ is a large one. The output of most heaters fall in between 25 to 100 KW.


For best results a gas heater for above ground pool should be fitted with thermostatic controls.
