Nettet11. jan. 2024 · In a condensing boiler, heat existing in the flue gasses can be captured and ‘recycled’ back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is ... Nettet3. feb. 2024 · One of the considerations for the kW output of your boiler is the amount of hot water it will need to output. The hot water flow rate of a combi boiler is expressed as ‘litres per minute’ (LPM), this tells you how quickly a combi boiler can heat hot water. Litres per minute vary from 9LPM to 25LPM flow rate.

NettetAn aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. When heating needs are lower in the spring and fall, 180°F is higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly. mast cable 14/5 awg
