The Brief
This project involved a three-bedroom, one-bathroom family home in Cedar Vale, Queensland. The previous water heater was a Rheem 100L electric water heater that was installed way back in 1977. The bonded vitreous enamel steel cylinder was still intact, but the electrical components finally gave way after an incredible 48 years of service.

The solution: Rheem Ambiheat® HDc-270 Heat Pump
J.Brown Plumbing and Gas installed the Rheem Ambiheat® HDc-270 Heat Pump after the customer chose to remain with Rheem. The upgrade not only provides increased hot water volume but will also assist with reducing energy consumption and improving overall efficiency.
Replacing an electric water heater with a heat pump is possible as they often use similar plumbing and electrical connections. Also, this Cedar Vale home had sufficient space outdoors, suitable for a heat pump installation as the system captures ambient heat from the surrounding air and transfers it to the water in the tank.
