Heat Ratings. The output of a radiator is measured in British Thermal Units (BTU.s) per hour. (So is air-conditioning, come to that!) 3000 BTU is roughly equivalent to a 1 kilowatt bar heater, just to give you some idea.
Rating Newest Oldest. Best Answer: The difference between 5w30 and 10w30 is that 5w30 flows better at colder temperature. If you live in a place where it gets cold often, or during the winter time, you will get better results using 5w30.Otherwise 10w30 oil is good enough, i usually use 5w30 all year round.ating Newest Oldest.

If you are considering charcoal, think 9,000 BTUs per pound and pellets about 8,500. A 30,000 BTU gas grill emits 30,000 BTUs in one hour, or about two pounds of propane an hour. BTU's do not indicate how quickly a grill will heat up, but can indicate how much fuel you will be using while you cook.f you are considering charcoal, think 9,000 BTUs per pound and pellets about 8,500.
