Best Indoor Electric Heaters For Large Rooms : Buying Guide

Are you thinking of placing an electric heater in your large room? If yes, remember a few things before purchasing an indoor electric heater for a large room.

1. Power Rating

It is one of the most important things you must consider while purchasing an electric heater for your room. It will give you an idea about power consumption and its overall performance. 

The room heater needs to have a minimum of 1500 Watts if you are buying for a large room.

2. Coverage Area

If you are confused with the power rating or cannot understand whether the room heater can provide comfort in your large room, it’s best to consider its coverage area. 

It is usually represented in square feet units. You have to then compare with the square feet of your room. Always invest in an electric room heater whose coverage area is more than the square feet of your room.

If you buy an electric heater with less coverage than the carpet area of your room, it cannot provide proper warmth in every corner. If you purchase an electric heater with more coverage than the room’s carpet area, then it increases the energy cost. Hence you need to pay a hefty electricity bill.

3. Control Options

Operating an electric heater manually within a gap of one or two hours is quite hectic and frustrating. So try to purchase an electric heater with a remote control to change the settings on any room corner.

Some room heaters even have a mobile application; you can easily control the device with your mobile phone.

4. Warranty

Most of the electric space heaters for large rooms are pretty expensive. In such cases, you must select an electric heater with proper working conditions and perform well for various years. 

However, checking an electric heater’s performance features is pretty difficult while purchasing. In such cases, you can check the warranty of the product. 

If any company gives a year warranty period, then you can trust that company. If any problem goes with the product within the warranty period, you can claim free service or, in the worst cases, free replacement.

So, we highly recommend you check the product’s warranty period before purchasing.
