Condensing boiler

Condensing boilers are special kind of boilers that are designed to make more efficient use of the heat they produce. When they heat up water, they not only heat the water up, but also the air around it. The warm air rises, taking some of the heat energy with it. So, the condensing boiler captures this lost heat and uses it to heat up more water and keep the house warm. This all happens inside tiny tubes and pipes, with the help of a fan. So, you don't see it, but your condensing boiler is doing a great job!
