Bundaberg Regional Council advertised a Request for Tender (RFT) for the construction of a solid shade structure and installation of an energy efficient heating system to cover and heat the existing Isis War Memorial Swimming Pool, located on Churchill Street, Childers. The existing pool had no roof cover and was open to the
elements. Council wanted to convert the outdoor seasonal pool to an indoor facility offering yearround swimming to its patrons with a minimum swimming temperature of 27-28°C. The solar pool heating system was limited to the proposed
new roof structure of 700-800m² and had to minimise Whole of Life Costs of the installation.
Assessing both the Council’s pool heating requirements and energy concerns, Supreme Heating proposed a two-in-one solution to meet the heating performance of the swimming pool together with responding to the facility’s energy needs all while minimising rooftop surface requirements.
Supreme Heating designed a solution consisting of a 33.60kW Heatseeker DualSun PV/T solar system coupled with a 216m² Heatseeker Plus traditional strip solar system and two 120kW inverter heat pumps to meet the heating requirements of the pool.
With a combined renewable thermal output of 285kWh, the system provides ample capacity to off-set the reliance of the heat pumps to maintain the Council’s 700,000L indoor swimming pool to average temperatures of 28°C throughout the swimming season.
The Heatseeker DualSun system is also capable of generating electricity at an average of 133kWh/day, reducing the operational expenditure of the pool heating system including the heat pumps.
With average energy savings of $31,266 per annum, the Council can expect their Heatseeker DualSun system to pay for itself within just 6 years based on current energy prices, minimising Whole of Life Costs. This innovative technology, aimed at reducing fossil fuel dependency also helps to off-set the operational expenditure, allowing budget to be placed back into community programs, extending the value of the facility and reducing carbon emissions.
