Heating System Safety Switches and Limits
Browse heating safety and limit switches at Stockpile Express and find a variety of options essential to the safety of your heating system: A flow switch safely prevents the boiler from firing up when the water flow ceases, a limit switch reads the temperature and determines when it is appropriate to send the air flow through, and a pressure switch ensures leftover gasses are safely eliminated before the boiler heats up. Whatever style of switch you're looking for, you'll find it in our collection of heating safety parts from Burnham, HTP, McDonnell Miller, and other top brands.
