Features to Consider in Large Room Space Heaters

If you are looking for a space heater for a large room then there are several things you need to consider. These things or features include:

a). Type of Heater

While buying these brands, you should choose the one that heats either by radiation or convection.

b). Type of Heater Installation

For rooms with high ceilings, it is better to use a portable heater because it can be installed close to the ceiling and when it radiates heat, it takes a long while before the warm saturates the atmosphere.
