Utilization of Photovoltaic Energy for Water Heating in Family House

The task of the work is to bring the issue of utility water heating closer together and to design a system that would be feasible in the layout of the building and constitute a fully-fledged replacement, even improvement, of the existing utility water heating system. The issue is viewed from two perspectives. From the point of view of using a photovoltaic system with a transducer and an electrical spiral, and from the point of view of using a photothermal system where the sunlight is directly converted to heat and its subsequent storage. It then compares several variants of a similar system from the economic and functional side
