The answer will be Infrared!!!
Infrared heaters save on the electricity cost.These well design heaters use the surrounding cool air and change it into warm air for satisfaction ..
Secondly there is really no installation.Simply plug them up (some may require to screw on feet) and get the heat set where you want it.
Also they have a large selection .The heaters normally come with fake fire &/or controls to turn the lighting down some……Remember to save money
