Choosing The Best Heater for Large Room

Here are some essential factors you should consider when purchasing heaters for large room.

Power 

The first and most important point you should look at is power. In general, one square foot space requires 10 watts of heat. Therefore, a space heater with a power rate of 1000 to 1500 watts should be suitable. You shouldn’t buy a car heater for your living room.

Type

Like any other device, space heaters come in different types, and they are:

Radiative Heaters

These appliances use radiation to warm objects and people in a particular space rather than heating the air. This ensures that the room maintains the heat at all times. One such heater from our product review is the Dr. Infrared Space Heater.

Convection Heaters

These heaters use a heating element to heat the oil or warm the air. Once the air is warm enough, the device pushes it into the room using a fan. Oil convection heaters may take time to heat up; however, they have a lower surface temperature than air convection heaters. The DeLonghi EW7707CM is an example of an oil convection heater.

Ceramic Heaters

Made from plastic or metal, they utilize electricity as the primary power source. They can either be convection or radiative style, but the heating element or plate inside is ceramic.These types are also budget-friendly and affordable to maintain. The Lasko 5160 heater is a ceramic space heater.

Temperature Controls

Most space heaters incorporate temperature adjustments into their designs. However, some will have fixed settings, and others will allow you to take more control by specifying the desired room temperature. 

Noise Levels

A noisy heater can be annoying, especially at night. Look for a product that uses terms like “silent heating” or “noise reduction.” These are good indicators of the heater producing little or no operation sound at all.

Thermostat

The thermostat will track the temperature of the room and monitor the heat output. You can find these with an LED or analog display to help you know the ambient temperature. An LED display is likely to be easier to read.

Design

The shape, aesthetic, and size all play a role in the functionality of the device. Therefore, make sure you choose a design that suits the size of your large room. Also, think about whether its appearance will complement the decor of your home.

Safety Features

These features are crucial, as they help prevent fire accidents from occurring. One of the safety features your heater should have is an automatic shutoff. This feature turns off the device automatically when it gets tipped over. Others include overheat protection, which prevents the internal components becoming too hot and your unit reaching unsafe temperatures.

Benefits of a Space Heater for Large Rooms

Apart from warming your large room, the best space heaters for large room are also:

Budget-Friendly

When you compare the cost of investing in a new heating system to the purchase of a space heater, it makes the latter a budget-friendly option in comparison. There are no professional installation costs, and maintenance is minimal as repairs are simple.

Energy Efficient

Space heaters come in various shapes and sizes. Despite these differences, these devices only require a few minutes to warm the room. Once it attains an ideal temperature, space heaters can maintain that, depending on how long you want it to operate. This helps cut down electricity costs and makes them energy efficient.

Portable

This one feature alone makes space heaters worth having. Unlike a central heating system or a radiant floor heater, you can move a space heater from one space to another. Most are lightweight, and this makes it easy to carry them around. If you don’t wish to switch on your entire heating system, space heaters could appeal.
