Can you use a pressure canner on an electric burner?
It is NOT recommended that you”pressure can” on a flat surface electric stove. The fluctuating temperature prevents the ability of keeping a steady pressure inside a pressure canner. A pressure canner reaches a much higher temperature than boiling (over 240 degrees F) and that will probably crack the stove top.

The BTUs of a gas burner should be 12,000 BTU or less . The housing for the burner must hold up to the high heat under the canner for long heating periods and not damage counter tops.
How much psi do I need for pressure canning?
At present, 240F / 10 psig [115 C / 69 kPa] is the most commonly recommended temperature. More recent interest in conserving nutritional and textural characteristics in canned food has led to some research with higher pressure (temperature) and shorter time processes.
Why can’t I use canner on glass cooktop?
Don’t use an enamel canner on a glass top stove. Most enamel stockpots and canners have indentations in the bottom , so the bottom of the pot won’t come in to complete contact with the stove top.

Typical BTUs of a gas stove should also include at least one high heat burner that generates 12,000-18,000 BTUs.
What is 15 pounds of pressure in a pressure cooker?
The trapped steam increases the atmospheric pressure inside the cooker by 15 pounds per square inch (psi), or 15 pounds above normal sea-level pressure . At that pressure, the boiling point of water is increased from 212°F to 250°F. This higher temperature is what cooks food faster.
What temperature is 15 psi on a pressure cooker?
When the pressure reaches 1 bar or 100 kPa (15 psi) above the existing atmospheric pressure, the water will have reached a temperature of approximately 120 °C (248 °F) .
