As noted in the introduction a low pressure boiler operates at under 15 psi, and thus has a lower temperature than higher pressure steam boilers. Water in low pressure boilers is heated up to 250ºF, limiting the steam pressure to 15 psi. Low-pressure steam may be more economical to produce than high-pressure steam. Less energy is required to create it and it does not wear on components as much as a higher pressure and temperature would. Steam boilers under 15 psi are capable of heat to provide to medical facilities, universities, offices, apartments. Some craft brew, commercial distilling processes operate with the low steam too. State regulations may offer fewer boiler operator skills to operate and service them, saving costs and open the way for more service techs when needed.
