Electric Thermal Storage (ETS) systems are conventionally programmed for participation in the typical Demand Response programs. Particularly, context of Dynamic Energy Markets (DEMs), ETS enables residential customers to actively participate lowering their energy costs. It is imperative build a model ETS-based heating thermal zone achieve precise indoor temperature predictions. This can also assist estimating demands, providing advantages during integration into DEMs. Accordingly, this work introduces grey box modeling technique predicting temperatures. leverages residual components capture differences between trained and experimentally recorded data, thereby highlighting prediction discrepancies. Subsequently, Least Square (LS)-based parameter estimation brick temperatures utilizing Quantile Regression (QR) Huber Loss (HL) functions proposed. Comparative results over 24-hour period with experimental data proposed method ensemble learning techniques such as Extra Trees Regressor (ETR) Random Forest (RFR) presented. The performs more accurate forecast than conventional without residuals techniques. reduction Mean Absolute Error (MAE) under 0.4°C compared real demonstrates better performance
