Convenient Fan Operation With Ceiling Fan Remote Controls
We’re living in a remote control world today. It wasn’t that long ago that people actually got up from their chairs to change TV channels or records on the stereo. Now many children’s toys are attached to remotes so that they don’t have to actually get down on the floor to play with them if they don’t want. I even received a remote-controlled digital picture frame for Christmas.
However, I will admit that in many instances, remotes make life easier. One of the things I wish I had was remotes for the ceiling fans. Wouldn’t it be convenient to be able to change the speed and turn them on and off right from your easy chair?
The new remote-controlled ceiling fans are perfect for many people. For example, a person who has difficulty getting around can use the remote to alter the fan’s operation. If you’re in the middle of a chore, such as rocking the baby to sleep while wanting less air blowing on him and not wanting to get up for fear of waking him, you can just zap to get the amount of air you would prefer to have without hardly moving at all. If you have children that like to jump to reach fan pull cords, a remote is a way to put a stop to that behavior.
If you’re like I am and already have fans that didn’t come with remotes, you’ll be glad to know that there are universal remotes available that will work on any brand of fans. If you have name brand fans, such as Hunter, Hampton Bay, or Westinghouse, you can also find a selection of remotes made to go with the models you have.
Reading reviews of the remotes on Amazon.com shows a wide difference of opinion when it comes to how well ceiling fan remote controls work. One customer will say that they work well, and another will tell you that their unit quit working after only a year. However, with the low cost of replacing the remote with another unit, this shouldn’t be a major problem. If you keep reading, you’ll find that even the original remotes that came with the fans had this same shortcoming.
Under Dash Air Conditioning
One of the recent developments in the field of air conditioners is the invention of the under dash air conditioning technique. In this technique, they are mounted under the dash board of the automobile. The cooling effect from that angle is great and the effects can be felt in all parts of the vehicle.
This is available in the form of two major types or models. The first model is designed in such a way so that it can be fitted under the dash board of the car without the need of the removal of the glove box. This type of model is available in various modes, like heat and cool or cool only. This model comprises a high capacity coil and a chrome face. The evaporator fitted in this model is complete in all regards and is equipped with all the controls. The model also comprises a valve for the control of the heater along with mounting brackets. It also comes with instructions which are easy to follow.
The second unit of the under dash air conditioning which is available has certain characteristic features which double up as advantages. This second unit takes comparatively lesser space vertically under the dashboard. This is made possible by using thin rectangular louvers. This second unit or model is also available in the cool only and the heat and cool modes.
The evaporator is also complete and consists of all required controls along with the valve, which is needed for the regulation of the feat (also known as heater control valve). Extremely easy to follow instructions are also part of the package along with mounting brackets. The under dash air conditioners comes in variety of dimensions. The most commonly used dimensions being 16 inches wide, half an inch deep and high.

The Friedrich ES16L33 Twintemp air conditioner is a great high end unit for the money. With a price tag around $1000, it should offer some decent features, and it certainly does that and more. The Friedrich ES16L33 is both an air conditioner and a heater as the “twintemp” part of the name implies. It can get you through the summer and winter in unparalleled comfort. Let’s take a look at some of the features it sports:
Ultra quiet working noise level
Unlike the noisy monoliths rattling in windows from days past, the Friedrich ES16L33 electric air conditioner does its cooling or heating work so quietly that it’s hard to tell it’s even on much of the time. This ability to function quietly is one of the hallmarks of a high end machine. You won’t be distracted by it, but simply warmed or cooled as the situation requires.
Energy Efficient
By cycling the fan with the compressor, the Friedrich ES16L33 is able to work in an energy efficient manner, saving its owner money on electric bills. Anyone who’s ever owned an air conditioner knows how they can gobble up electricity and send monthly expenses skyrocketing. This unit takes this into account and saves consumers dollars wherever possible.
Multiple heating/cooling settings
The Friedrich ES16L33 Twintemp air conditioner has 3 different heating and cooling speed settings, plus a fan only setting. These multiple settings allow for fine tuning of the comfort level of a room so that there is never a sense of being too chilly or too hot.
Thermostat
This model has a sensitive thermostat that not only monitors changes in heat levels but anticipates them. So you don’t have to wait until the room is sweltering or freezing before it turns on. You can rest assured that it will get your indoor space to a comfortable temperature and keep it there.
Rotary Controls
The rotary controls give a sense of greater control to the settings. No more worrying about sticking buttons or so called fancy touch sensitive controls that break. These controls are easy to turn and put on the desired settings.
8 way airflow control, fresh/stale air exhaust vents, and filters
This air conditioner offers unmatched control of airflow so that the air you’re breathing is always the purest and freshest it can be. It channels in the fresh air and sends the stale air outside the house with sophisticated 8 way airflow control. The Friedrich ES16L33 electric air conditioner also sports antimicrobial filters to further purify the air you’re breathing.
At a cooling capacity of 16200 BTU per hour and a heating capacity of 9.8 EER, this conditioner is plenty strong. It can handle small or large rooms with ease.
The Friedrich ES16L33 is a truly high end machine that will reward consumers for their investment many times over.

Some Things You Didn’t Know About Panel Heaters!
It never fails to surprise me that despite the huge amounts of Panel Heaters sold in the U.K, most people buy them without really knowing a great deal about them, never mind which ones to buy or even what they should be paying for them! Hopefully, once you have read this, you will be able to overcome these hurdles and make the right choice of Heater that is suitable for you.
The first hurdle to consider is which room is it needed in? is it going to be in a corridor? and also where am I going to place it? – Well, thankfully the modern day Panel Heaters are extremely compact and slim fitting, capable of virtually fitting into any room or corridor, and so take up the minimum amount of space. There are now available in the market place some ultra-slim models that can be so unnoticeable, you would have thought they were invisible! So really, you can install Panel Heaters just about anywhere – bathrooms, bedrooms, living rooms, conservatories, offices – in fact anywhere you require quick and instant heat.
You will find Heaters will give you the luxury of heat at any time, and will warm up any room much, much quicker than many other heating systems, and with all quality models coming with accurate temperature controls and built-in timers, you can always be in control and decide how much heat you actually want. On top of this, you will not hear the Panel Heater hard at work, as all the quality models operate in virtual silence.
An important consideration when looking at any form of heating for the home or the office, is what will my heating bills come out at? – Well, whilst it is true that Panel Heaters are connected to your electric supply and sometimes electrical forms of heating are not always the cheapest methods around, but what you will find with they are in fact one of the most cost-effective forms of heating methods around. This is because they provide you with heat only when you want it, and so save energy and save you money! You can use it to temporarily heat up your bedroom when you first wake up by use of the pre-set timer control, or you can of course use them to heat up the office during the day when the temperature drops. A further advantage is that as they can be placed in any virtually any room, you can use them just to supplement the temperature in that room, or just to boost your existing heating system during the colder snaps of winter.
As an alternative to the popular traditional Panel Heaters, you will also find on the market, Radiant. These have the added advantage of being able to circulate the heat around any room, and so provide an even heat distribution. These tend to be the choice of heat for conservatories, where heat circulation is important. And for those of you who like the all important bathroom at bath-time to be lovely and warm in the coming cold winter months, there has now become available a Radiant Bathroom Heater just for this purpose.
But, back to the traditional – You will find there are many different makes and models around, with the market leaders tending to be Dimplex, Steibel Eltron and Delonghi, with some up and coming brands like Sunrise, Sunburst and the Mirage Slim-Line Panel Heaters equally proving popular.
On the price range this will vary as to the type of Panel Heater you are looking for, so this will be ‘horses for courses’. As a guide however, you should expect any of reasonable quality, to start at around 45 pound plus Vat for the low wattage basic models, rising up to 155 pound plus Vat, for the top-end models, with some designer glass panel models up in the region of 220 pound plus Vat.
So there you have it, some things you did not know about Panel Heaters!
Determining Energy Savings Using Utility Bills – A Winning Method For ESCOS
Introduction: Energy Savings Tracking Methods
After installing energy conservation measures (ECMs), Energy Service Companies (ESCOs) often determine the energy savings resulting from the project and present the savings results to their customers. A common way to calculate energy savings is to measure the flows of energy associated with the ECM, and then to apply spreadsheet calculations to determine savings. For example, a chiller retrofit would might require measurements of chilled water supply and return temperatures and kW. The benefit of this approach is that the ECM is isolated, and that only energy flows associated with the ECM itself are considered.
This method is described as Option A or Option B in the International Performance Measurement and Verification Protocol (IPMVP). Table 1 presents the different options. Option A requires some measurement and allows for estimations of some parameters. Option B requires measurement of all parameters. In both options, calculations are done (typically in spreadsheets) to determine what energy savings. Option C uses utility bills to determine energy savings.
Some ESCOs Have Limited Options
There are many situations where Option A or Option B (Metering and Calculating) is the best approach to measuring energy savings, however, some ESCOs insist upon only using Option A or Option B, when clearly Option C would be most appropriate. If the ESCO was a lighting contractor, then Option A should work in all cases. Spot measurements of fixtures before and after, agreed upon hours of operation, and simple calculations can be inserted into a spreadsheet that can calculate savings. The same spreadsheet can be used over and over. However, for ESCOs that offer a variety of different retrofits, it is necessary to be able to employ all options so that the best option can be selected for each individual job. Controls Retrofits, or retrofits to HVAC systems are typically excellent candidates for Option C.
However there are drawbacks with metering and calculating savings and these can include:
- Greater expense
- Difficulties convincing the customer of the appropriateness and veracity of the method and savings numbers
- Inability to handle interactive or many difficult ECMs.
ESCOs that do not have the capacity to employ all options are at a disadvantage over those ESCOs that can employ them all. Specifically, we want to address those ESCOs that only employ Option A and Option B. These ESCOs may encounter the following problems due to their limited offerings:
- Measurement and Verification costs can be greater, which lead to higher project costs, which can limit the energy projects that the ESCO can sell. The lack of Measurement and Verification options overall can make the ESCO less competitive, and hurt the financial performance of the ESCO.
- Using Options A or B sometimes require the customer to understand and approve of complex energy calculations. These options are often difficult to explain to customers who insist upon seeing savings in their utility bills. Customer satisfaction can suffer if Option C is not made available to customers who want to see savings on their bills.
- Options A and B cannot handle difficult ECMs. The methods used to determine savings are inaccurate, and make large assumptions that cannot be borne out if a third party consultant is hired to oversee the savings determination process.
These issues are discussed in more detail below.
Cost of Utility Bill Analysis vs. Metering and Calculating
Measurement and Verification should cost between 1% and 15% of the project cost. Metering and calculating savings often has costs associated with labor and equipment. As many project configurations are different, projects typically require unique configurations of sensors, placements of sensors and savings calculations. On more complicated ECMs, only highly skilled energy professionals can determine which measurement devices should be applied, and to what components. Manipulating data, and finally creating spreadsheets with engineering calculations also requires skilled personnel who command high wages. Metering equipment also has a cost, and for many projects, metering equipment, or control points, have to be purchased, and remain on the job for years.
Of course, there are cases where metering and calculating is the least expensive and the most desirable method. If an ESCO only provides a lighting retrofit, then measuring a selection of lighting fixtures before and after the retrofit, and producing a spreadsheet that determines savings is the best option.
On the other hand, utility bill analysis is inexpensive. With specialized utility bill analysis software, clerical workers can create the Measurement and Verification analysis. Bills are entered, weather imported, a linear regression performed, and reports made. Capital need not be sunk into metering equipment or control points or into long hours of analysis and data manipulation. Typically for utility bill analysis, measurement and verification costs are a fraction of what costs for retrofit isolation savings are – ranging between 1 and 5% of project costs.
Explaining Savings Numbers to Customers
Customers understand utility bills. The reason they entered into an energy savings contract is often triggered by the desire to lower their energy bills. Retrofit Isolation methods do not address the customer’s utility bill. A project may be saving energy, but the utility bill may actually be increasing. Retrofit Isolation does not address this at all. ESCOs need to be responsive to customer’s needs, and this is done through communicating in a manner that the customer’s understand. They want to see the savings on their utility bills – this is a method they would trust.
In addition, customers are sometimes mistrustful of energy service companies that provide savings numbers that the customer cannot understand. Although the calculations in the spreadsheet may appear perfectly reasonable to the energy analyst, to a customer who is not well-versed in math, the calculations may remain incomprehensible, and the customer is thereby required to trust the energy service company, sometimes leading to mistrust. Energy savings calculations should remain as simple as possible and explained in a manner that the customer can understand. This makes the customer’s job easier, and reassures the customer that the energy service company is acting in a truthful manner.
For these reason, more and more customers ask for Measurement and Verification using utility bills.
Difficult and Interactive Energy Conservation Measures
For many energy conservation measures, Retrofit Isolation is the best option. This would include lighting savings, savings from energy efficient motors, and from other non-weather dependent energy users.
However it is very difficult or impossible to measure savings for some energy conservation measures. Still, some ESCOs insist on using Retrofit Isolation for these difficult measures. For example, engineering calculations can be made estimating the savings to be had by shutting down air handlers at night. But, assuming that the air handlers receive chilled water from a chilled water loop shared with other air handlers, how is one to measure energy savings? Fan savings are easy (assuming the unit is constant volume), but in order to calculate savings, several estimations need to be made, which result in an estimate of energy savings, just as accurate before the retrofit took place as after it took place. Suppose the unit is a VAV system, at what percentage would the fan have been running? Suppose the cooling coil and/or heating coil modulated to meet a changing supply air set point – how are the fan CFM, cooling and heating loads to be calculated if the unit is not running and measurements can not be made?
Controls retrofits are difficult to measure and quantify directly. Usually, however, when a controls or commissioning measure is enacted, more than one item is adjusted, which further complicates an already difficult task. Suppose a partially working economizer was fixed, in addition to putting the fan on a variable speed drive, in addition to shutting off the air handler during unoccupied hours, and finally upgrading the chiller plant. Each of these measures would interfere with the savings calculations of the other. How can one calculate chiller savings, when the loads have changed so dramatically via the economizer, reduced hours and reduced air flow? This is a very difficult task, that most likely cannot be done with an acceptable degree of certainty.
Complicated cases like this require utility bill analysis to measure and quantify savings. The procedure is very simple, inexpensive, and easy to explain relative to many Retrofit Isolation methods.
Benefits of Utility Bill Analysis
The benefits of utility bill analysis to calculate energy project savings are as follows:
- Utility Bill Analysis, by its nature, is relatively simple, and does not require complicated engineering analysis.
- Utility Bill Analysis is relatively inexpensive, as it requires less skilled workers, less time and no dedicated equipment.
- Utility Bill Analysis provides savings numbers in a format and method that makes sense to the customer.
- Utility Bill Analysis is the best method to handle complicated energy conservation projects, or projects which interact with each other, making assessment of individual measures impossible.
- ESCOs can use the fact that energy savings is determined using the customers’ utility bills as a selling point.
Utility Bill Analysis and Changes in Weather
Unfortunately, a simple comparison of pre-retrofit and post-retrofit utility bills is usually not an effective method to determine energy savings from ECMs. Weather varies from year to year, and affects the amount of heating or cooling energy usage, which can interfere with actual utility savings numbers. For a fair analysis, utility bills should be “corrected” for weather data, which results in a reasonable savings determination. Linear regression is applied to utility usage versus degree days to determine pre-retrofit utility usage patterns, which are then compared to post-retrofit utility usage to determine savings. Unfortunately, the scope of this paper is limited, and cannot present the method in detail. Weather-correcting for weather is easy, however, as specialized software, used by ESCOs around the world, simplifies the weather correction process and presents savings reports.
Drawbacks of Utility Bill Analysis
Facilities may change their energy usage patterns, by installing more equipment, building additions, occupancy changes, etc. This upsets the existing utility bill comparison of pre-retrofit to post-retrofit usage. These changes need to be monitored and accounted for with Baseline Modifications.
There is a certain amount of randomness in utility bill comparison. So many factors influence the amount of energy usage in any given month, and they cannot all be accounted for. As a result, if you are trying to show savings that is less than 10% of the total electricity load, then the randomness in the bills may seriously interfere with the accuracy of your savings calculations.
If you track savings by comparing utility bills, you will only be able to track total savings for a given meter, but you will not be able to separate out the savings for different Energy Conservation Measures (ECMs). For example, if you installed a lighting retrofit, an energy efficient chiller and a control system in a hospital, you will not be able to tell how much energy is being saved by the control system. Energy analysts try to do break out the savings for each ECM occasionally, but they are only making educated guesses.
Conclusion
When an ESCO approaches a performance contract, there are several measurement and verification options available. Those ESCOs that only have at their disposal a limited set of options are often spending too much money on measurement and verification, and therefore are held back from selling larger projects, and limit their own success.
Customer satisfaction may suffer when ESCOs only offer Retrofit Isolation approaches to Measurement and Verification, as customers may want to see savings in their utility bills. ESCOs who refuse to speak in the same language or terms as the customer may suffer decreased customer satisfaction.

Electric Radiant Heat – Low Cost House Warming
We as consumers dream up all kinds of ways to upgrade our homes. From stain-proof carpet, to solar panels for decreased energy bills; we are always looking for something that improves our standard of living, and hopefully, reduces our standard of spending.
Radiant Heat is one of these upgrades. It is a luxury you won’t think about, but you’ll miss if it’s not there. When most people think of radiant heat, “Warm Floors” typically come to mind. Radiant heat, however, does a whole lot more that warm floors.
Radiant Heat is capable of heating an entire house, and is far more comfortable and efficient than forced air or convection heating.
In space-heating, occupants feel more comfortable even when the space air temperature is maintained lower than typical forced air heating. Radiant heat results in less heat-loss from a room. Forced air registers and baseboard heat strips are always located on outside walls between windows. These systems heat air that comes in contact with the external windows and walls to temperatures much higher than the desired room temperature. This results in more heat-loss from the space. Heatizon System’s products provide a uniform heat flux from the floor into the space, resulting in less heat-loss from the room.
Mass Warming results in less temperature variations in the space being heated. The flooring material is heated by the element which then radiates the heat into the space. The floor surface can be maintained at a very uniform temperature which prevents the hot and cold temperature swings that occur as other systems cycle on and off. Warming the mass of the floor results in what is called thermal capacitance. This allows the space to remain warm even when extreme temperatures occur. Essentially, heat energy is stored in the mass of the floor and other objects in the space. This applies to any type of floor–wood, concrete, tile, etc.
Efficiency levels of Heatizon Systems are excellent. When compared with a heat pump, forced-air furnace or baseboard heating system, Heatizon Systems low-voltage products are more efficient watt for watt. An article in the July, 1996 ASHRAE Journal, “Radiant Heating for Thermal Comfort” reported on experimental results comparing a heat pump, baseboard heat and radiant heat. The radiant heating system consumed 33% less energy than the heat pump system and 52% less energy than the baseboard system.
Reliability of Heatizon Systems are superior. The entire system is solid-state, has no moving parts to wear out, and has nothing that requires routine maintenance. There are no water lines to break or crack. Our products have been satisfying the needs of hundreds of customers since 1979. Both z-mesh and Tuff Cable are easy to repair in the event they get cut or damaged. The controls allow for power failures or spikes, yet brings the system back on-line as quickly as possible.
Comfort of radiant heat is superior because the radiant heat flux is uniform throughout the heated space. There are no “point-source” hot spots like there are in baseboard and forced air systems. Thermal comfort is sustained as the system cycles on and off, because the heated mass temperature remains almost constant.
Convenience of installation is superior to any other system. There is no ducting to deal with, no lost floor or wall space. Other than a thermostat, Heatizon Systems products are out of sight. Retrofitting is easy. Adding the system to an existing space is much easier than installing a hydronic or high voltage system.
Safety is a major advantage of the Heatizon System. Heatizon Systems products are ETL listed to UL standards 1673,1693, and 1561.
Quiet and clean. The Heatizon System produces no more noise than a light fixture. There is no fan starting and stopping, no filter to change or clean, no valves to wear out, and no pipes to rattle.
Life-Cycle Costs are less, especially when heating exterior concrete surfaces. The cost to replace a driveway, sidewalk or patio is many times the cost of the Heatizon Systems products.
