Quantum Energy heat pumps. At that time the hotels average 145,000 litres per day of hot water use was costing around US$80,000 per annum. However it was not just cost that drove this decision.
Return on Investment that the Royal Plaza on Scotts had achieved was
a remarkable 1.36 years.
The Solution The decision to install Quantum Energy high performance units was influenced by the ability to combine large numbers of Quantum’s high efficiency Titan units and manifold them together forming a system which would cater for the hotel’s peak demand periods, without having to install extra storage capacity. This installation and resultant energy savings was studied by Singapore’s National Energy Efficiency Committee (NEEC) and was found to have saved over US$28,000 of diesel fuel per annum and US$7,000 of annual boiler maintenance costs. Further the Singapore NEEC found that the Return on Investment (ROI) that the
Quantum Energy’s International Sales Manager Mr. Robert McLean comments that “while these figures are very commendable in themselves, one should remember that this was done in 1997. Diesel prices then were around US$0.70/litre. Now with current pricing the payback (ROI) for a system installation such as in this particular case, would be closer to only one year.” Additionally, in 1997 while far sighted organisations such as the Royal Plaza on Scotts hotel were concerned with environmental impact, no–one was talking carbon abatement figures. Mclean has calculated that this installation alone saves around 35 MT of carbon dioxide emissions every year.

are a total solution for replacement of electric, gas or diesel hot water systems in commercial environments. The Quantum range includes self storage units and expands up to large water sourced models for hotels and commercial operations which have a large ongoing need for hot water. All Quantum models feature proprietary tankwrapTM technology which delivers excellent cost savings and reduction in green house gas emissions.

Example of Potential Savings Potential Financial and Environmental Calculations A 300 room hotel with 80% occupancy wishes to evaluate both the financial and environmental impacts of changing current diesel fuel boiler water heaters to Quantum Eco Hot Water heat pumps. The hotel currently uses around 78,000 litres per annum of diesel to cater for hot water demand.
