Buying Guide for Natural Gas Wall Heaters
A natural gas wall heater is more than just another home appliance but is an investment. You should never overlook good buying practices when shopping for the best natural gas wall heater.
BTU and heating areas
How large or how small is your living area where the heater will be set up? You need to confirm this to make sure that you’re using an efficient natural gas heater that’s right for your home or room. Take note that a 30,000 BTU is enough for a 750 square feet room or area while a 20,000 BTU can warm a room that’s 400 square feet.

Also, this feature ensures your safety in the event you forgot to power off the appliance.

All your reviews quote the 2 dimensional AREA heated (measured in square feet). But a room is a 3 dimensional SPACE (measured in cubic feet).
