Room Heating Series: All You Need to Know About Oil Filled Radiators

Winter is coming! Now is the perfect time to dry-clean all the comforters and blankets, dust up the room heaters and prepare for the approaching season change. Needless to say, room heating is an important aspect that requires attention as soon as the mercury begins to drop. While markets are flooded with choices, it is imperative to buy the right heating device based on your bespoke needs to stay warm and comfortable all through the season. We bring you a series of articles to introduce you to all kinds of room heaters. These will help you choose the right one for your home or office space and get the maximum bang for your money.

Let’s begin the series with sleek, stylish and high-performance oil filled radiators (OFRs).

What is an Oil Filled Radiator?

An oil filled radiator, more commonly known by its abbreviated name OFR, is a convection heater used for heating up small indoor spaces. This room heater is filed with oil, which is electrically heated. OFRs do not involve burning oil. They only use oil as a heat reservoir.

OFRs are also known as oil heaters, oil-filled heaters and column heaters.

What Do OFRs Look Like?

Oil filled radiators comprise a number of thin metal columns, known as fins. The front panels of OFRs have the power (On/Off), knob to set heating positions and other thermostatic controls. The heating element is located at the base of the heater. Usually the devices rest on castor wheels, which make them easy to move from one place to another. There is a power cord as well as the facility to wind it up and store it out of the way.

How Does an OFR Work?

The thin metal fins of an OFR have cavities that are filled with silicone oil. The heating element heats up this oil, which in turn stays hot for a long time. This oil flows around the metal column cavities, transferring the heat to the walls of the fins through convection and then to the surrounding areas of the room through convection and radiation.

Do note that this heated oil has very high boiling point (so it stays in liquid state) and high specific heat capacity (so it can store a large amount of thermal energy in a relatively smaller volume)!

Are OFRs Efficient?

OFRs are best-suited for bedrooms and small-to-medium sized enclosed spaces. They come with thermostats that prevent inefficient heating. This means, if your room is already warm, you can choose how much warmer you would like it to get. So the heating would be more efficient and customized to your needs. This feature also makes oil filled radiators more economical to run as compared to other kinds of room heaters.

The power consumption of oil heaters typically falls between 2000 – 2500 Watts. Their power rating is directly proportional to the number of columns (fins) and their length. The wattage determines their operating cost; more wattage equals lesser cost while a lower wattage involves higher cost. Therefore, a 1000 Watts heater will take half the time to reach a desired thermostat setting as compared to a 500 Watts heater.

Some oil heaters come with a fan. This increases the air flow over the heater. As more and more colder air from the room comes into contact with the heater, there is a significant improvement in the rate of heat flow from the heater into the room. This rate of heat flow is even higher when the temperature difference between room air and heater is more.

Are OFRs Safe to Use?

Oil filled radiators are relatively safe to use, especially when compared to fan heaters. They also come equipped with a host of safety features that offer additional peace of mind. For instance, there is overheat protection as well as tip-over switch that cuts off the power when the appliance is tilted or knocked over. Both of these features eliminate the risk of fire or other electrical mishaps.

Do remember that OFRs should not be kept in damp areas such as laundry rooms or bathrooms. The moisture and humidity present in these areas may damage the heating element or reduce its efficiency.

Also, you should never attempt to dry clothes on an OFR or keep flammable materials such as clothing, bedding or plastic toys near the devices they can easily catch fire.

Conclusion

OFRs may be slightly expensive when compared to other kinds of room heaters, but they are matchless in terms of aesthetics, performance and longevity. This makes them a popular choice in modern homes looking for sleek and stylish room heating solutions.

Water Coolers at the Workplace Keep Employees Hydrated, Healthy & Happy!

3 Digital BAnner

Water is the most essential nutrient for our body and is crucial to our survival. Drinking an adequate amount of water to keep the body hydrated is the first essential step towards enjoying good health.

Why Is Hydration Important?

Good hydration allows our body to perform at an optimal level, control its temperature and process every biological, chemical and mechanical process taking place within it. Hydration facilitates the following functions in our body:

  • Carry Oxygen: Water helps to deliver oxygen all over the body
  • Boost the Brain: Since almost 77 – 85% of our brain consists of water, better hydration improves mental acuity. It also helps our brain to create hormones and neurotransmitters
  • Metabolize Fat: Adequate intake of water makes our kidneys and liver work efficiently and optimizes excess fat metabolism
  • Improve Digestion: Water breaks the food components down and helps to boost the digestive process and nutrient absorption in the body.
  • Enable Better Detox: Water helps to flush out toxins and waste material from our body.
  • Keep the Bones and Joints Happy: Water lubricates our joints and minimizes pain and wear and tear caused due to friction.
  • Regulate the Body Temperature: Hydrations controls spikes and drops in body temperature and affects respiration and sweating.
  • Make Cells Grow: Water allows the body’s cells to grow, reproduce and live
  • Lessen the Impact of Injuries: Water acts as a shock absorber for the brain and spinal cord and lessens the impact of injuries
  • Keep your Skin Soft and Supple: Water prevents dryness and the onset of wrinkles. Well hydrated skin looks smooth, healthy, glowing and young!

If the body is a machine, any deficiency or loss of water can cause a malfunction or downtime.

Another important fact to note is that while a large percentage of our body is comprised of H2O, we also losing this essential nutrient constantly and in multiple ways – while or without doing any laborious work – and mostly without being aware of it.

Therefore, replenishing that lost water is crucial to our overall well-being!

Importance of Proper Hydration at the Workplace

Staying hydrated at work might seem like a challenge for most of us. Besides, even if our daily job keeps us behind a workstation all day, it’s so much easier to grab a quick cup of coffee or a can of soda and skip a glass of water, isn’t it? Well, that’s where the problem lies! By the time we manage to chug a sip or two of water, we are already dehydrated and that’s what makes us feel tired and sluggish.

Did you know that dehydration is one of the main reasons why we have an unpleasant day at work? Not drinking enough water can trigger immediate problems such as headaches, joint and body ache, fatigue, lack of concentration and short term memory loss, as well as feelings of nausea – in short, the ultimate #buzzkill formula that leaves us with an irritable mood and a bad day at work. Bad mood equals less productivity as well as unnecessary altercation with colleagues.

Can Office Water Coolers Solve the Problem?

Yes! The office water cooler might have a bad reputation for being a place where employees kill time, however, in actuality it can do just the opposite! Statistics show that offices with a water cooler actually get more work done as compared to those without one!

When employees are properly hydrated, they feel good, think quick and work well.

Plus, they are less likely to guzzle down calorie-laden sugary drinks if they have easy access to fresh, clean drinking water at the touch of a button.

Also, it’s cheaper (read mostly free) for us to grab a glass of water than to run down to the cafeteria for a can of soda!

The mother of all benefits – for those of us trying to lose/watch our weight, a water cooler at the workplace would encourage a higher intake of water to keep those mean calories in check.

All-in-all, water coolers promote a culture of staying hydrated and help to constantly replenish the H2O loss by dispensing cool, clean and fresh drinking water. This not only improves our health, mood and workability at the office but also our lifestyle outside of work.

How To Choose Water Heater Capacity

Given India’s geographical diversity and the natural change of seasons, the need for warm water is quite intrinsic. A water heater or geyser thus is a common household fixture found across the length and breadth of our country. But how big or small a water heater should you get – now that decision requires some serious thinking through! Let’s take a look at 3 important factors that determine the size of water heater to buy:

  1. Place of Installation

Different locations require different capacities of water heaters. For example, in kitchens, hot water requirement is minimal (perhaps, only to wash utensils). Therefore a small capacity water heater (around 1L – 3L) serves the purpose adequately. If you take a bucket shower, a 10L-15L storage water heater will serve your purpose; for an overhead shower, you should go for a slightly higher water heater capacity of 25L. However, if you love taking long, luxurious dips in a bath tub, a larger capacity of 35L – 50L geyser is what you need.

  1. Kind of Climate

Colder climates have lower ambient temperatures. In such climes, the heating element of a geyser takes longer to heat the water to a desired temperature. A large capacity storage water heater (about 10L – 35L) can heat up and store larger quantities of water and help to maintain a steady supply of the same over a longer duration of time (ideal for rushed mornings!) For places with relatively warmer climate, an1L-3L instant water heater will suffice.

  1. Number of People Using Hot Water

The capacity of a water heater is dependent on family size (obviously!). For larger families with more members requiring hot water within a defined period of time, large capacity water geysers are imperative. Fewer people require lesser hot water for their use and can do with a small size geyser.

The following chart will come handy when you decide to buy a water heater:

No. of Persons Recommended Water Heater Capacity
1 – 2 6 Litres – 10 Litres
3 – 4 15 Litres – 25 Litres
5 – 8 35 Litres – 50 Litres
