Water conservation in solar domestic hot water systems

Energy Conversion and Management, 1993
Abstract The effect of using solar domestic hot water heating systems on water consumption is investigated for different system configurations. Random samples of actual data for water consumption, obtained from the water authority, together with data from solar heating collector manufacturers for systems installed, have been analyzed.

Production efficiency of hot water for domestic use

Energy and Buildings, 2012
This paper examines the efficiency (in terms of energy use and carbon emissions) with which 5 different types of domestic water heating systems employed in the UK are able to produce hot water for sanitary use. A method of normalisation is employed allowing results from case studies with different systems and usage levels to be compared.

A Smart Domestic Hot Water Buffer

IEEE Transactions on Smart Grid, 2012
Demand response is seen as a key technology to help the introduction of large volumes of intermittent renewable energy and to help mitigate the effects of the increasing load on the electricity distribution grid. A large and diverse number of control mechanisms are proposed for demand response, while multiple industrial companies are designing their ...

Corrosion in Domestic Hot Water Systems

CORROSION 1973, 1973
In our previous paper1 describing initial results in the study of corrosion of steel, copper and galvanized steel in domestic hot water service, tests were conducted mainly in high alkalinity waters (200-400 mg/l).

A model of the domestic hot water load

IEEE Transactions on Power Systems, 1996
The electrical load required to supply domestic hot water is an important load for two reasons: (1) it represents a large portion (30 to 50%) of the domestic load; and (2) it is a load which can easily be controlled by the consumer or the supplier, because the use of the hot water need not coincide with the heating of hot water.

WATER TREATMENT For Domestic Hot‐water Supplies

Anti-Corrosion Methods and Materials, 1958
Corrosion and deposition problems arising from either hard or soft supply waters become of increased importance when the water is heated. In this article the nature of scale formation is discussed, also the corrosion of iron pipes and the use of sodium hexameta‐phosphate as a means for minimising the trouble so caused.

Domestic Hot Water Heating in nZEB

2019
Domestic 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 performance of a thermosiphon solar domestic hot water system with hot water removal

Solar Energy, 1984
INTRODUCTION Thermosiphon (natural circulation) solar domestic hot water systems were investigated, both experimentally and numerically, by Close[l], Gupta and Garg[2], Ong[3], and Young and Bergquam[4]. Close used a 1.6m 2 (17.3ft 2) collector and a 113.6L (30gal) storage tank, while Ong utilized a 1.4m 2 (15ft 2) collector and a 106L (28gal) storage ...

The continuing risk of domestic hot water scalds to the elderly

Burns, 2000
Elderly 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.

Domestic Hot Water Heating Using Hot Air Solar Collectors

Journal of Energy, 1979
The 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.
