[en] Nowadays, condensing technology is widely used in space heating. This paper presents a model that predicts thermal performance of condensing boilers. The structure of the model is similar to the one of a conventional boiler model with a dry heat exchanger at which a wet heat exchanger is added to simulate the heat recovered by condensation. Tests have been performed on two household 24 kW condensing boilers (gas- and oil-fired boilers). The experimental results are compared to the simulated values. According to the results, the model correctly predicts the thermal efficiency of the boiler. Indeed, predicted values are in good agreement with measured values (if one takes into account the measurements uncertainties).
