Abstract
- In this article, the heat storage for small dwellings with seasonal storage system is in Estonia modelled. The system consists of low temperature underground insulated unit, auxiliary buffer tank inside the building and PV panels as an energy resource. In order to evaluate the heat storage and extraction processes, a more detailed seasonal storage model has been designed. This work's novelty is the usage of solar PV panels as an electricity producer for supplying energy for space heating with seasonal storage. For the energy storage media sand/soil is used, but it is acknowledged that modelling with other materials is also. The energy is carried to the storage unit and also extracted by the register of water pipes. The media around the pipes in the model is divided into slayers, which simplifies the calculation of heat exchange processes in the unit. The buffer water tank is used for short-period energy storage and for heating the tap water. The system is designed such, that energy is not supplied to the main unit in spring and summer. The main storage is used in summer and early autumn. By this design energy loss within the main unit is minimised. The results show, that when the main unit has sufficient capacity and proper insulation thickness, it is likely to adequately cater residents´ the heating and warm water demand throughout the year. Energy loss in case of a shorter periods of high temperature in the storage tank is smaller.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
