Does anyone have experience with using Liquid Propane as a fuel for a gas cooktop with high capacity burners? I noticed that the BTU rating for the same burner using LP is lower in some cases than natural gas and higher in other cases. We are looking at units with an 18,000 BTU burner. Does a gas cooktop work as well with LP?

Hello,

We have been using LP for our gas cooktop for almost 5 years now. The cooktop is equipt with both a MAXIMUM and MINIMUM(simmer) burner.

It has suited us well, in fact, I can't really tell the difference between when we used the same stove with natural gas.

Hope this is helpful!

Because the molecules of LPG are smaller than those of natural gas, all manufacturers require that the gas orifices be changed over to LPG whenever it is used as fuel. This change will ensure that the appliance behaves as closely as possible to the way it was designed to operate when using natural gas. Usually the alternate orifices are color-coded, and are provided by the manufacturer with the stove, along with specific instructions as to how to change them over, and how to adjust the air/fuel mixture at each burner for optimal performance.

As to whether the heat output in BTU's will be identical, or not, when the orifices are changed to LPG, the best source to ask is the manufacturer of the stove you are intending to buy.
