The flow rate is less, so the pump horsepower will be less, the pipe size is smaller, and the return water temperature allows the boilers to condense at design. There is a cost increase in the AHU. The coil would have to change but that is a small portion of the total cost.

WebPre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature … WebA boiler that runs more is going to be more efficient because it will spend less time re-warming the water that cooled down while waiting for the next call for heat, which causes it to have to flame up longer to reach the water temperature set point again. If your boiler is cast iron, 140° is a safe minimum. WebFor a modern combi boiler, the radiator heating temperature should be set for a flow temperature of between 60 and 70°C. Any higher than this and the boiler won’t enter condensing mode and be at its optimum efficiency and performance. In spring and Autumn months, consider reducing the boiler’s radiator temperature further - to around 50 or ... cultural diversity in infant toddler care
