WebYour boiler specs will often show the maximum flow rate that your boiler can provide at a specific temperature, for example 12 l/min at 40 degrees centigrade. This shows how much water it can send to your taps at that temperature. WebOne thermal flowmeter measures the waste gas flow, while the other four thermal flowmeters provide submetering of this gas stream to each boiler. Another four meters measure preheated (200°C, 392°F) combustion air to each boiler, allowing the boiler control system to optimize the fuel-to-air ratio.
