WebFor example, with a flow temperature of 80°C and return temperature of 50°C using natural gas, ... If the flow out of the boiler is 70°C and return is 40°C then the average system temperature is likely to be 55°C, lower than if the system was operating at say 80/60°C. This means that the heat emitter needs to be larger to deliver ... WebJan 17, 2013 · Country. 17 Jan 2013. #4. If the return is 55° C or lower then the boiler will be condensing well. That means the flow can be up to 75° C but the lower it is the more efficient the boiler operation. Weather compensation aims to heat with the lowest flow temperature necessary to provide the required heating. Tony.

WebDec 21, 2024 · The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C. WebThis secures optimum boiler protection and reduces cost of operation. Condensing boilers can benefit from FLOWLIMIT technology as it sets the maximum system flow in order to maintain the right return temperature and allow for condensation. This ensures higher operation efficiency by utilising the latent heat potential.
