Domestic Hot Water Heating in nZEB
2019Domestic hot water (DHW) is needed for personal hygiene and washing. In low-energy and passive buildings, energy consumption for DHW water heating can exceed the amount of energy used for heating the building. DHW systems are included in the energy use assessment of the buildings as one of the so-called EPBD (Energy Performance of Building Directive ...

The continuing risk of domestic hot water scalds to the elderly
Burns, 2000Elderly people are particularly at risk of accidents in the home and with an ageing population, they constitute a large proportion of scald victims. We have seen several elderly patients every year in our own unit who had sustained domestic hot water burns.

Barriers to the reduction of domestic hot water temperatures
Safety Science, 1995Abstract Studies have shown that domestic hot water temperatures in New Zealand homes are dangerously high, leading to an increased risk of sustaining a serious burn when contact with the hot water is made. The reduction of household hot water temperatures is a key preventive measure for reducing the risk of injury.

Domestic Hot Water Heating Using Hot Air Solar Collectors
Journal of Energy, 1979The efficiency of a finned coil type heat exchanger mounted in the solar collector air outlet duct of a space heating system for providing hot water in the spring, fall and summer months was determined with a series of equations and graphically represented.

Energy performance of domestic hot water systems
2017Residential sector consumes 70 % of the district heat. The domestic hot water system consumes 27 % of the total thermal energy consumption in these buildings in Riga. According to the mandate of the European Committee for Standardization (CEN) European standards for assessment of the energy performance of buildings have been developed.

Dynamic simulation of a domestic hot-water system
Applied Energy, 1991Abstract The paper describes the building and testing of a domestic hot-water system in a laboratory of the Department of Mechanical Engineering, University of Canterbury, New Zealand. The system included not only conventional household devices, but also solar panels and a waste-water heat exchanger.

Analysis of solar domestic hot water heaters
Solar Energy, 1980Abstract The performance of several generic types of solar domestic water heating systems is compared using a simulation approach. Types of systems studied included those using single and double tanks and those using direct and indirect methods of transferring solar heat to potable water.

Failures of Domestic Hot Water Storage Tanks
Corrosion, 1946sometimes attempt to explain the fail ure by saying it is due to "the chemicals in the water." This bit of information often disturbs the consumer, and he usually concludes that water that will eat out a galvanized-iron tank will most certainly ruin his stomach.
