Urban Solutions Fact Sheet 2009
By EDB Singapore
Half of the world’s population are now city-dwellers and this trend is swiftly
rising. We expect this urban population to double from 3.3 billion
in 2007 to 6.4 billion in 2050. More specifically, by 2025, we expect 16 out
of 27 megacities in the world to be in Asia 1 . With this rapid and
unprecedented urbanisation trend, governments and city planners around
the world need to cope with the challenges of urban planning,
environmental pollution, traffic congestion and security threats
amongst others. Urbanisation is hence a global trend of mega proportions
that brings with it many challenges and opportunities.

Gas Heaters, Clean Energy For a Greener Singapore
By Associate Professor Lee Siew Eang
This independent study quantifies the positive effects of using Gas Water Heaters and provides a cost analysis (based on retail price) for reference.
Some of the key findings of the study are as follows:
• The fuel switch from electric storage heaters to gas continuous flow heaters may result in carbon emission reductions of up to 86% at the national level. This is equivalent to 0.5 million tons of carbon emissions annually;
• In terms of energy saving, the study shows that there is a potential savings of up to 64% in energy use with respect to total energy use for hot water generation in Singapore, when all households switch from electric storage heaters to gas continuous flow heaters. This saving translate to 700,000 MWh or S$149 million per year at the national level;
• The estimated carbon emission reduction as stated above is equivalent to the planting of up to 500,000 trees per annum to provide the carbon sink for the absorption of the same amount of carbon; or equivalent to the removal of 72,780 cars from the road;
• At individual level, a switch from electric instantaneous heaters to gas continuous flow heaters may result in savings ranging from 14% to 44% of the total hot water energy use. Similarly, a switch from electric storage heaters to the gas continuous flow heaters may result in a saving of up to 91%, in terms of energy cost, depending on the level of usage and temperature settings.
• A cost study has shown that for new developments, the increase in installation cost for a gas continuous flow heater may be recovered from energy saving within a period of 9 months for a small private apartment, and a maximum of 2.1 years for a large private apartment. For apartments the existing electric storage heaters have been retrofitted to gas continuous flow water heater, the payback period ranges from 1.5 years to 3.2 years for small private apartments and large private apartments respectively.
