The committee at the Pinnacles Apartments Caloundra contacted us wanting an economical hot water heating solution for their Apartments. After looking at what was currently heating their water we knew we could offer a far better solution. After being supplied with the appropriate data of water usage at different times of the day we could now design the system best for them. We installed 8 x Sanden Hot Water Heat Pumps, connected them to the existing continuous ring main hot water system. After a little balancing of the system The Pinnacles Apartments are now achieving a staggering 91% savings in the running costs from switching over to Sanden Heat Pumps from LPG Burners.
