Tekapo Springs uses a combination of LPG and electricity to fulfill their large hot water requirements. DETA was consulted with to provide advice on how to improve energy efficiency at the site focusing around the ratio of LPG to electricity used, and how to utilise both resources to maximise efficiency.
In terms of hot water output Tekapo Springs pays around four times more for LPG as they do for electricity. DETA therefore investigated opportunities to maximise the sites ability to utilise their hot water heat pump as opposed to the LPG fired boiler. The solutions were tiered allowing Tekapo to choose the level of investment they wanted to commit to.
By the site visit alone $9,000 of energy savings were immediately implemented for no capital cost. Further to this, savings around control systems as well as installation of pump VSDs were identified and proposed to the client.
