SILVEL, VEVOR, LF BROS, and HCALORY diesel heaters. I compared heaters for noise level, air speed from the heaters fan, heater air temperature, 12 volt energy consumption, fuel consumption, warm up time, cool down time, performance at warming up an 800 square foot building. I also tested the use of vegetable oil and motor oil as a fuel source for the heaters. Finally I disassembled the heaters to compare build construction. I purchased all of the heaters to ensure an unbiased review.
