Limbrick, Lancashire. UK Weather. -3 C in the north-west as the early morning low sun highlights central heating steam emissions from residential property in Long Lane. Boilers produce long plumes of steam with air humidity also playing an important part in the condensing processes. Flue gases contact the cold humid air, and then begin producing long plumes of tiny water droplets. Credit: MediaWorldImages/AlamyLiveNews
Our country has been reliant on gas for domestic heating for over 100 years. We switched to a cleaner source of gas in the 1960s and now burn natural gas in our homes. The supply of natural gas is running out so in 2005 the decision was made to install high-efficiency boilers, known widely as condensing boilers. The clue to answering the question “Is my boiler on fire” is in the name: Condensing. Let us explain what is going on. Your boiler does what you do. Think of it a bit like your breathe on a cold day. When you breathe in, you warm up the air from outside in your body, as you breathe out, the warm breathe reacts with the cold air and you see a plume or water vapour. You will notice this doesn’t happen when the air temperature outside is too warm. The air humidity also plays an important part in the condensing process. When you breathe out, the air mixes with the outside air. Once that mixture reaches 100% humidity it condenses. Our breath leaves our body at about 90% humidity which is why it condenses further away from our mouths. This is the same principles as a condensing boiler.
