What do you mean by working pressure of a boiler? - QuoraWorking pressure is the same thing as the maximum allowable working pressure or MAWP. The two terms are used interchangeably. Per the link below - MAWP is the maximum pressure at which the vessel or equipment is allowed to function at a specif...
What is the safe pressure for a hot-water-heating system?The maximum pressure I am allowed it to get to is 30-psi, because, at that pressure, the pressure relief valve will open. This is typical of residential hot-water boilers. As far as temperature is concerned, my boiler will shut off if the temperature exceeds 205 F. THey do not want the water in there to boil.
