What is a modulating condensing boiler? Modulating condensing boilers (mod-con boilers) can increase combustion efficiency to about 96%, up from the 80% efficiency of non-condensing boilers. They provide a range of firing rates to match the variable heating load of the building.
What does it mean when a boiler is modulating? A modulating boiler is the most energy-efficient boiler on the market. The boiler doesn’t turn off every time the heat has reached the house and doesn’t turn on each time the temperature in the house needs to go up.
How does a modulating burner work? Modulating burners are designed to control the burner output (size of flame) to match the boiler variables and load requirements. During this process, the burner is designed to stay at the correct fuel-to- air ratio across the complete firing range to ensure the maximum combustion and boiler efficiency.
What is the most efficient condensing boiler? It is suitable for both new builds and the modernisation of homes, and the compact boiler size makes it suitable for all spaces. This is an A-rated condensing combi boiler with an efficiency rating of 89.1%.

What happens to the molecules in water as it boils?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
