	HIGH PRESSURE BOILER	LOW PRESSURE BOILER
1.	In this type of boilers, steam pressure is above 15 psi.	In this type of boilers, steam pressure never exceeds 15 psi.
2.	Hot water pressure always exceeds 260 psi	Water pressure never exceeds 260 psi
3.	Temperature will always be greater than $250^oC$	Temperature will never be greater than $250^oC$.
4	For the safety due to high working pressures, these boilers are required to be monitored all the time.	Since these boilers work on low working pressure, they don’t need continuous monitoring.
5	Applications involve production of steam in industries and in power plant	These are used for water heating and steam from it used to heat rooms.
6	For similar size, the output is relatively high.	For similar size, the output is relatively less.
7	High maintenance is required	Low maintenance required
8	Operating costs are relatively higher	Operating costs are relatively low.
