Solar thermal roof-top installations offer the potential to meet an important share of residential water and space heating demand in Germany. These systems are subsidised with grants under the so-called market incentive program. The political goal is to encourage the adoption of renewable energy...

With the increasing amount of building renovations in Austria, the potential increases for replacing conventional national gas heating systems with heat pumps (HP) and thereby reduce CO2 emissions particularly when combined with solar photovoltaics (PV). The Austrian subsidization scheme for HP...

Increasing the use of heat pumps is an important measure for reducing carbon emissions in the heating sector as well as natural gas imports. This report uses an electricity sector model to investigate the effects of an accelerated expansion of the heat pump stock on the German electricity sector...

Solar collectors are the main components of a solar heating system. The collectors collect the sun’s energy, transform this radiation into heat, and then transfer this heat into a fluid, water or air, which has many household or industrial applications. This paper introduces a new technology...

Present work is focused on building a TRNSYS simulation model of solar water heating (SWH) system using heat pipe evacuated tubes, hybridized with conventional fuel (i.e., natural gas) backup to provide uninterrupted thermal energy supply. An experimental facility was developed to validate the...

The hybrid heating system consisting of loop heat pipe solar collector (LHPSC) and ground source heat pump (GSHP) was proposed to maintain greenhouse temperature in Harbin (the coldest provincial capital of China) in this paper. The thermal model was developed to predict transient greenhouse and...

In the context of promoting "carbon peaking" and "carbon neutral" energy, the complementary use of multiple energy sources has been further developed. This paper studies a type of combined solar thermal- Photovoltaic (ST-PV) power generation and heating system to explore the coupling of various...

Electrification of heating, particularly with highly efficient heat pumps, is increasingly viewed as essential for reaching the targets of the Paris Climate Agreement. In China, rural heating has long represented a major contributor to local air pollution, poor indoor air quality, and...

This study investigated the crisis of energy from which Gaza has been suffering over the past years. It ventured to highlight the growing needs for energy and the urging need to use renewable and sustainable sources of energy such as solar thermal energy. Much specifically, it gave much...
