The 'from and at' rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create 'from and at 100°C',at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler. Shell boilers are often operated

Efficiency of Boiler. Actual Evaporation Rate is rate of steam produced from boiler under a certain pressure and feed water temperature is equal 30 °C. Equivalent Evaporation Rate is rate of steam produced from boiler under atmospheric pressure and temperature 100°C. Boiler Horse Power: 1 34.5 / 15.65 / Bhp lb h kg h 10
Gas water heaters are relatively cheap and low maintenance. Oil-fired water heaters cost more, but usually produce hot water faster. Whether gas or oil, if you heat with hot water rather than forced air, then the same boiler that heats your home can also heat the domestic hot water, saving the cost of a separate heater.
