Solar water heating

Solar water collectors for heating swimming pools are increasingly being used in New Zealand. Typically these collectors are unglazed rubber or plastic mats / panels that work best at low temperature differentials between the ambient air temperature and the pool water temperature. Computer simulation of pools in Auckland and Dunedin has shown that these solar collectors are effective at raising the temperature of pool water, particularly where a pool cover is also used.

Tracey and Robbie Torrance of Richmond upgraded to a solar water heating system to reduce their power bills and increase the availability of hot water. This case study describes how Tracey and Robbie reached the decision to install solar water heating, covered the costs of the project with help from an EECA ENERGYWISE_TM loan, and worked with their installer for a hassle-free upgrade.

Dairy farmers and technical experts share their experiences across four demonstration projects using a variety of solar water heating and waste heat recovery systems to reduce energy costs in the dairy shed.
