Why You Need an Oil-Filled Radiator Room Heater:

If you’re living in a country that has weather extremes of winter temperatures falling below 15 degrees Celsius, you would appreciate the value of a room heater more as opposed as treating it as a luxury item. Ensuring good warmth in the rooms can make the home more habitable, hence one gets to enjoy time sitting in one corner of the living room without feeling the need to increase the central heating. In this case, especially in cold areas, room heaters serve the purpose of warming some places in the house without the need to warm the whole house.

Types of Room Heaters:

There are three main types of room heaters to choose from:

  • Oil-Filled Radiator (OFR) Heaters: These are best for large rooms. The heater uses electricity to warm the liquid inside and generates heat by passing it through the fins. OFR heaters do not make the atmosphere very dry. This kind of heaters will suit severely humidity-sensitive people. They are a little bit higher than of regular room heaters, usually estimated at around 10000 rupees. But it gives good heating by not compromising on convenience.
  • PTC Fan Heaters: A ceramic coil with a fan is used in these heaters to provide forced warm air inside the room. While these are less expensive, costing between rupees one thousand five hundred and four thousand, these can also cause dry air and lead to itching or irritated skin.
  • Halogen Heaters: As for halogen heaters, they are the least expensive and are usually meant for smaller or personal spaces. They mostly heat the space where they are turned and cannot be recommended for families with children.

What to Consider When Buying Oil-Filled Radiator Room Heaters?

Safety and efficiency are just a few of the reasons why OFR heaters are gaining popularity in modern times. They are however different from any other heaters like the OFR heaters, which again do not dry up the air in the room so the chances of a person having any skin irritation or suffering respiratory complications are reduced. Such heaters also have safety arrangements like overheat protection, safety on tilt, and auto shut off among others.

Key Features to Look for in an Oil-Filled Radiator Heater

  • Number of Fins: As much as people would say heats transfer and make a room warm, it is the size and the number of fins that determine how long the OFR heater will take to warm the medium-sized bedroom. For a medium bedroom, a 9-finned heater is okay. For larger areas like living rooms or halls, opt for an 11 or 13-finned heater to ensure even heat distribution.
  • Wattage: A typical OFR heater has a wattage of 2900W but this is split into 2500W for heating and 400W for the PTC fan and most OFR’s heaters are also designed this way. Therefore the higher it is the faster the heater will make the room warm, but also more power will be consumed in doing this. Check the wattage for a right wattage power ensuring efficiency in heating the room while reducing power consumption.
  • Safety Features: Look for heaters with features such as overheat protection and tilt safety as safety features. These features make sure the heater turns off by itself when either it gets overheated or it falls over without supervision.
