Energy Savings

Performance & Savings

The Sanden Eco® Plus Hot Water Heat Pump System delivers:

  • Industry leading energy efficiency – uses only 20% of the energy required by a conventional electric storage hot water system.
  • Innovative technology – up to 50% faster heat recovery than currently available hot water heat pumps.
  • Industry leading quality & performance, with the highest level of STC rebates of currently available hot water heat pumps.
  • Class leading warranties, backed by Sanden’s 35 years of operation in Australia.

As the Sanden Eco® Plus Hot Water Heat Pump System uses R744 (CO2) refrigerant technology, the amount of electrical energy required to heat the water is significantly less than that required by a conventional electric hot water system.

In fact, the Sanden Eco® Plus Hot Water Heat Pump System consumes 0.84kW^^ of electricity to generate 4.99kW^^ of heat (COP = 5.96^), which equates to 20% of the energy used by a conventional electric system. Consequently, with the Sanden Eco® Plus Hot Water Heat Pump System, you can save up to 80%* of your conventional electric hot water energy costs!

Case Study: Cost savings using a Sanden Eco® Plus Hot Water Heat Pump System vs a conventional electric hot water system

This table presents electricity consumption figures recorded by a Sanden customer, who replaced his conventional electric Rheem Hot Water System with a Sanden Hot Water Heat Pump System, on 4 October 2010.

He lives in the Sydney Metro area (i.e. STC Zone 3), has a family of 4 people (husband, wife & 2 children) using hot water and uses Off-Peak Controlled Load 2.

The reduction in usage achieved for the 2010/11 period compared to the previous year was approximately 80%, while the reduction in cost for the same period was 77%. This was despite a change of supplier and a 18.7% more expensive tariff.

Did you know that Heat Pump technology is more energy efficient than Solar?

During the period 2009 – 2013, the Campbell Creek Energy Efficient Home Project** compared the energy usage of three homes, each with different types of water heaters.

Test results for the period January to December 2012, confirmed that the Solar Flat Panel system used 38% more energy than the Hot Water Heat Pump.

  • House 1 (CC1) – Electric, 50 gal capacity, EF=0.86, usage= 60 gal/day, set temp=120oF
  • House 2 (CC2) – Hybrid Electric Heat Pump Water Heater, 50gal, EF =2.4, set temp = 120oF, usage=60 gal/day
  • House 3 (CC3) – Solar Water Heater, 85 gal, EF =0.91, set temp = 120oF, 60 ft2 collector area, electric pumps, usage=60 gal/day
