Abstract

The increase in energy prices and the demand to reduce carbon emission is attracting the attention to the implementation and integration of diverse heating technologies such as heat pumps, solar energy, gas boilers, CHP and electric heaters. Heating applications for integrated technologies include district heating, domestic small-scale applications and commercial large-scale buildings. Energy from flooded coalmines and water from other sources could also play an important role in improving energy efficiency of heating and cooling systems. Stratified thermal storage and hot water tanks are likely to become key to energy efficient heating, particularly when implementing a mix of technologies. A stratified hot water tank, and even natural stratified reservoirs, are expected to play an important role in the integration of several heating technologies that operate efficiently at different levels of temperature with reduced implementation cost. This paper discusses the new innovative technology to improve stratification, namely ‘the water snake’, and an automated test rig to evaluate the new stratification method for energy utilisation using energy storage of hot water. A fully computerised system is used to evaluate the performance. The results clearly indicate that the test rig has been successful for the automated testing of the technology. Moreover, the results show that the water snake as a new technology for stratification is successful in minimising mixing and turbulence inside the thermal energy storage. The results prove that the technology could be implemented for a wide range of applications to enhance the efficiency of heating systems in buildings as well as district heating and cooling applications.
