Basics of hot water heating boilers - Specifying Engineer

Sep 18, 2020 · The heat exchange surfaces for hot water boilers must be in contact with water to prevent the heat exchange surface from overheating. Low level water sensors are required to ensure this. Fuel and air are controlled in concert, but the quantity of fuel delivered is a function of thermal input required to control the boiler temperature.
