Optimization of Photovoltaic Self-consumption using Domestic Hot Water Systems

Journal of Sustainable Development of Energy, Water and Environment Systems, 2018
Electrified domestic hot water systems, being deferrable loads, are an important demand side management tool and thus have the potential to enhance photovoltaic self-consumption.

Design and Analysis of a Two-Stage Cascade System for Heating and Hot Water Production in Nearly Zero-Energy Buildings Using Thermoelectric Technology

Buildings
This paper proposes an innovative system that integrates two thermoelectric heat pumps (one air–water and the other water–water) with two thermal storage tanks at different temperatures to provide heating and domestic hot water to a 73.3 m2 passive-house-

A new test procedure to evaluate the performance of substations for collective heating systems

E3S Web of Conferences, 2017
The overall heat demand of a single dwelling, existing out of space heating and domestic hot water production, decreases due to higher insulation rates.

Thermal Stratification in Solar Storage Tanks: Long-Term Modelling and Efficiency Analysis

Energies
The storage tank plays a key role in solar thermal installations, as thermal stratification allows high temperatures to be maintained in the upper region while keeping the return temperature to the collectors low.

Characterisation of the thermal performance of a novel roof ridge solar hot water system

Journal of Facade Design and Engineering, 2018
The development of novel systems for the on-site integration of renewable energy in buildings is increasingly demanded for the reduction of the energy consumption resulting from domestic hot water, heating and cooling usages.
