How Do Condensing Boilers Work? Condensing boilers heat homes by burning gas or oil as fuel. When this is done, water vapour is released as a by-product and instead of being wasted and released through the flue, a condensing boiler recovers this latent heat; passing it through their heat exchanger which then cools and condenses it back into a liquid form (i.e. condensate).
