We use a small 1500W ceramic space heater that is not adequate. Today we looked a Lowes and saw a much larger heater, but is was also only 1500W. So my question is what kind of heater would be bette...
Yup all heaters are about 1500 watts or about 5200 BTU. You can have radiant, convection or forced air. Expensive or cheep they all produce the same heat.
If it is that cold we run our 1200 watt convection radiator style on max and supplement with the furnace as needed.
You could run two or more but you might start tripping circuit breakers.
