Know About Electric Space Heaters and Their Benefits

Space heating is the best way to get adequate and cost efficient heating. Unlike central heating, it provides heat only for the limited space, conserving the electricity and thus reducing the electricity bill. Space heaters are best suitable for homes or offices with few rooms, in which limited number of people are present.

Many types of space heaters are available in the market today. Based on the type of power source used, they are commonly divided into three types. They are electric heaters, gas heaters and kerosene heaters. Of the three types, electric heaters are most preferred and are considered as most efficient as they have many benefits over the other two types. Here, we will discuss about the types of electric heaters and their benefits. We have also provided some tips on how to handle electric heaters efficiently.

How do they work
Electric heaters (in fact all space heaters) are broadly divided into two types based on the way they transfer the heat. They are Radiative heaters and convective heaters. Here, we will discuss only about the electric space heaters.

Radiative space heaters
They are the most efficient and are famous for their direct heating method. On switching on the radiant heaters, they emit radiations and heat the objects directly without heating the surrounding air. They are instant heat generators. Infrared heaters are popular among them. Quartz bulbs, halogen lamps and metal coils are commonly used as heat generating elements in these heaters. The heat generated by these elements is focused in a particular direction through reflectors.

Convective space heaters
Convectional type of heating involves heating the space by gradually heating the air in the room. This heated air when circulated in the room, results in increase of temperature. These heaters do not provide instant heating, as heating the air needs time. There are different types of convectional heaters like fan forced heater, ceramic heaters, oil filled heaters etc.

Compared to convectional space heater, radiant heaters are more energy efficient as they directly heat the objects, instead of heating the air.

Electric ones are very efficient and effective. They provide ample heating in the space, within the minimum usage of equipment. Due to the concentrated heating, not much heat is wasted. Unlike the gas or kerosene based traditional heaters, they don’t carry risk of fire and carbon monoxide poisoning. Electrical heaters are environmental friendly as they do not use Propane, Butane, LPG gas or Kerosene. Electric space heaters are very simple to use. They are easy to maintain and most importantly are clean, as they don’t involve burning of any coal or wood. They are portable and are easy to install and operate.

How to use them effectively
Space heaters by themselves are very effective. Right usage of these heaters further enhances their productivity. A fan forced electric space heater with a blower can also improve heat transfer. While purchasing an electric heater, see that you select the one which has got two or three heat regulating options, as this will enable you to adjust the heat to the required temperature easily. Having a thermostat to your electric heater will not only make you adjust the temperature of the room, but also prevents from overheating of the room.

Safety tips
Though electric space heaters are many times safer than the traditional heaters, they have to be handled properly. Improper electric connections, overheating or corrosion may lead to major accidents. Therefore, in order to avoid these incidents, follow the few safety tips given below.

  • In case of using an extension cord, use a heavy duty cord made up of 14 gauge wire or larger.
  • It is advised to buy a portable space heater with a tip-over safety switch, which shuts off the heater automatically, if the unit gets tipped over.
  • The electric heaters have a high risk of fire outbreak. Hence, space heaters with low surface temperatures or the heaters provided with thermal cut out switches should be used.
  • It is better not to operate a defective heater and get it repaired immediately on finding the missing controls.
  • Place the electric heaters away from the moist areas, such as bathrooms, which may lead to shocking hazards due to corrosion of heater.
  • Keep them on a stable surface.
  • Regardless of all the above safety measures, it is compulsory that you install a smoke detector to prevent huge destruction.

Electric space heaters are the best heating options when used properly. They are energy efficient and economical. Considering all their features, electric space heaters stand as a good choice of heat sources.

Aquarium Heaters – Making the Best Choice For Your Fish

Unless you plan to keep only cold water fish, you’ll need to choose an aquarium heater. Fish cannot provide their own body heat. This is often thought of as being “cold blooded,” but this is a misnomer. The temperature of these animals is directly related to the temperature of their environment. The ambient room temperature generally will not provide enough warmth for your fish, so you will need to invest in a proper heater. Maintaining a proper water temperature is an essential step in keeping your fish healthy. Most fish will need to be kept in water that is between 78 and 80 degrees Fahrenheit.

Aquarium heaters are available in different types based on how and where they supply the heat. Most heaters have a control which allows you to adjust the heat to the proper temperature and most contain a thermostat which keeps the temperature at an even level. Here is a quick look at your different options.

Submersible and Immersible Heaters

As the name implies, submersible heaters are made to be fully submerged in water. Immersible heaters are mostly submerged, however, the controls must remain above the waterline. Immersible heaters frequently hang from the back or side of the tank. Both submersible and immersible aquarium heaters are effective and relatively inexpensive. Because they are inexpensive, it is easy to keep an extra heater of this type on hand as a back-up in case your primary heater fails. Because at least part of the heater may show in the tank, these can be difficult to camouflage; generally submersible heaters are easier to camouflage than immersible heaters. These heaters may be made from glass, plastic, aluminum or titanium alloy. Some models can create “hot spots,” but in a tank where the water circulates well, this is generally not a problem.

Substrate Heaters

These types of aquarium heaters heat the water from the bottom up. These heaters are installed below the rock, gravel, sand, or other substrate material used in your aquarium. They provide heat that is more uniform than submersible or immersible heaters. Typically they are completely hidden by the substrate material, making them a very attractive choice. If you have an aquarium with live plants, this heater is a good choice as it promotes plant growth. These heaters are also the most popular style in Europe.

The drawback of this type of heater is that it is installed under the substrate. While it is easy to install such a heater when you are initially setting up your tank, if your tank is already established, it will have to be taken down to install or repair such a heater.

Filter Heaters

Filter heaters are one of the newest kinds of heaters available. These heaters consist of heating blocks that are placed inside the filter. This heats the water during the filtration process, providing even heating. These types of heaters are camouflaged inside the filter itself. These types of filters can be expensive and are not as common.

What? Watt!

Once you’ve chosen your heater style, you’ll need to know what wattage will be required to keep your aquarium at the right temperature. Generally, you should multiply the gallons of water your tank will hold by 5 to get the number of watts to purchase. For example, a 20 gallon tank would require a 100 watt heater. If your aquarium is large, you may wish to use more than one heater to provide the necessary wattage. For example, a 50 gallon tank requires 250 watts of heating power. Two 125 watt immersible heaters, one at either end of the tank, would provide the right amount of heating. The other advantage of using more than one heater is that in the event of a heater failure, the temperature in the tank will not plummet as quickly, giving you a little extra time to get another heater installed; when you have a considerable financial investment in fish and animals, this can be important.

Keeping an Eye on the Temperature

An essential part of the heater purchase is a separate thermometer. This will allow you to double-check your water temperature and make any necessary corrections, and to spot a heater thermostat that may be beginning to malfunction. Fluctuations in temperature can cause stress to your fish, undermining their health. Thermometers are available in several styles, from glass thermometers that float in the tank, to digital models that sit outside the tank.

Handling a Heater When Its Hot

If your heater has been on, turn it off and unplug it for a minimum of 15 minutes before you remove it from the aquarium. Otherwise the heater can crack from the change in temperature, or overheat. Even if you will not be removing the aquarium heater, it is a good idea to unplug the heater when you are working in the aquarium, changing the water, for example. Aquarium heaters are electrical appliances and electricity and water DO NOT MIX. Always use proper safety precautions. Make sure that the heater is properly submerged in water when it is in use, whether it is a style designed for complete submersion or only partial immersion; this means keeping an eye on your water level and replenishing the water in the tank as needed.

Thinking of Buying an Electric Wall Heater

Looking to buy an electric wall heater, but don’t know were to start. Here is a simple buyers guide that will help you make the correct buying decision

Buyers Guide

When shopping for an electric wall heater, for a new construction job (not replacing an old heater) there are several things to consider.

1. Heater sizing by wattage
2. Voltage – basic guidelines
3. Noise Level of the heater
4. Thermostat / Timer
5. Looks of the grille
6. Heater location
7. Recessed vs. Surface mounting
8. Feature to = Look for or avoid.

1. Heater sizing (how big is the room you want to heat)
The first and most important step is “how big is the room you want to heat “The heater has to be sized so it can heat the room on the coldest night of the year. The quick rule of thumb is for house build in the last 20 years, or older houses that have be renovated with more insulation, and new doors and window is 10 watts per sq ft for ceiling 8′ or lower or 1.25 watts per cubic foot for ceilings higher then 9′

Example small room:
Square footage = 10’W x 15’L = 150 (standard 7 to 8 foot ceiling)
Watts per Sq Ft = 10 to 12 watts (new construction few windows use 10 watts)
150 sq ft x 10 watts = 1,500 watt heater (select a 1,500 to 2,000 watt heater)

Example larger room:
Square footage = 25’W x 15’L = 375 (standard 7 to 8 foot ceiling)
Watts per Sq Ft = 10 to 12 watts (new construction few windows use 10 watts)
375 sq ft x 10 watts = 3,750 watt heater (select a 4,000 watt heater)
Always give yourself a safety factor by averaging up.

Cubic Foot Rule of Thumb,
Room size 10′ H x 15’w W 12’L = 1800 cubic ft
1800 cubic Ft x 1.25(your constant) = 2250
This room will need a minimum of 2250 watts of heat

2. Voltage
Knowing your, and having the correct voltage, is right up there as one of the most important thing to know and understand before you purchase and electric wall heater. Electric wall heaters come in 120 and 240 volts. Some electric wall heaters only come in 120 volts, and some only come in 240. Most homes in the United States have both 120v and 240v in there house, If you have a electric stove, range, dryer or water heater in your home those are all running on 240 voltage. A standard 120 volt wall heater comes in 500 to 1,500 watts which can heat a room between (50 to 150 sq ft room) if you have a room bigger then 150 sq ft you have to have a 240 volt heater. A standard 240 volt wall heater comes in 1000 to 4,800 watts which can heat a room from (100 to 480 sq ft room).

A common over site is buying and or installing a wall heater with the wrong voltage If you install a e heater to the wrong voltage bad things can happen.

– 120v to a 240v heater will give you of the wattage.
– 240v to a 120v heater will burnout the heater and void the warranty.

If you are not sure on your voltage you will want to consult a licensed electrician. We stock almost every heater you see on line and ship the same day if in stock so we can get it to you pretty fast

( FYI Notes ):
– 110 volts, 115 volts, 120 volts, 125 volts
– (All four voltages will work with the same heater)
– 220 volts, 230 volts, 240 volts, 250 volts
– (All four voltages will work with the same heater)
– 208 volts is NOT the same as 240 volts – it’s a total different

3. Noise level
All fan forced wall heaters will make a noise. I tell customers over the phone when browsing our website the more expensive the wall heaters the quieter its going to be (this rule does not apply to our commercial grade wall heaters with a CFM grater then 100 ) because the internal parts are of a higher quality. If noise is not an issue any heater within correct wattage and voltage you parameters will work.

4. Looks of the grille
White this one is subjective, it is an important part of the buying process is the looks of the heater. Every heater we have except the Broan WH9815 is made with a metal grille with a powder coated painted finish. If you have question on the color of a certain heater feel free to call us

5. Thermostat
Controlling a wall heater can be done with a built-in or wall thermostat. Certain models have the option of one or the other, while some just have option for just built in or just wall mounted only…If you are not sure call or email us

The built-in thermostat the knob is mounted on the outside of the heater. It works just like a wall mounted heater by turning it clockwise you turn the power on and you set the desired room temperature. Turn it counterclockwise you will lower the desired temperature wanted and if you turn it all the way to the left it will turn the unit off.

Wall thermostats are not available on all wall heaters, for those that do offer them this is how they work. A wall mounted thermostat is usually mounted on the other side of the room. A 120v or 240 volt power line is pulled behind the sheetrock to the wall heater. To set the temperature of the heater once again turn the knob clockwise to you desired room temperature.

When using a wall thermostat with this wall heater be sure to place it on an internal wall, ideally across from the windows. Avoid drafty areas, direct sunlight, and other heaters & electronics devices that can put out heat like computers or TV’s. Make sure you don’t place it behind a shelf or too close to pictures what will affect airflow around the thermostat’s sensors.

6. Heater location in your room
Find a spot on an interior wall close to the outside wall. Make sure you avoid any obstructions like a chair or couch, or hanging items like drapes. By using a nearby wall you can avoid cutting into your wall insulation. The idea is to heat your cold wall first and the rest of the room will fall in line.

FYI Notes:
The factories recommend the heater should be mounted at least 8″ from the floor, 8″ from an adjacent wall, and if you are mounting it high at hast to be at least 8″ from the ceiling, 3 feet from furniture… If you have question on mounting location(s) please consult your local or town or city code inspector for the final answer

7. Recessed vs. Surface mounting
– Recessed mounting simply means you cut a hole in the sheet rock wall.
– Surface mounting on a brick or block wall, your heater will mount on the wall instead of inside the wall.

8. Feature to look for or avoid.
– Back box include – Look for it – All heaters have back boxes but some times you can order them separately. The back box separates the heating element from touching the interior wall or insulation. Plus it’s a code violation.
– Thermostat operation ranges – Look for it – Some people want to run the heater at the lost temperature to keep the water pipes from freezing. If the operating range of 50 to 90 F, the heater will not go down to 40 F no mater how low you set it the thermostat.
– Summer Fan Switch – Avoid – This is used for commercial building applications, all it means it that the fan will run but the heater will remain off.
– Heavy Duty Grille – Avoid – Another commercial building application, the greater the foot traffic the higher the odds of someone smashing in the front grille of your wall heater. Unless you have a hotel dolly rolling around your home you more than likely don’t need the added cost of a heavy duty front grille.
– Tamper resistant built-in thermostat Avoid – Another commercial building application, this is used on office buildings, banks, hotel front vestibules.
