Gas flow rate calculations are used extensively in the disciplines of chemical engineering and process engineering. Flow rate calculations through pipes are often challenging because pipes can vary in diameter along their length.
WebDec 19, 2024 · Does lowering your boiler's flow temperature save money? It can, yes. A study published by the Heating and Hotwater Industry Council (HHIC) in its Heating Up to Net Zero white paper shows that you can make a saving of 6-8% on your gas bills by lowering a combi boiler's radiator flow. WebFlow temperature is the temperature of the water running through your radiators, pipework and system. There are advanced design calculations that can help determine the flow temperature, however for this technique we set the boiler flow temperature to 55 degrees, which virtually guarantees condensing efficiency savings.
