NewGen Solar & Heat Pumps are proud to introduce the latest Sanden Eco hot water system model: The Sanden Eco Plus hot water heat pump system.

Sanden Eco Plus is a ground-breaking product, highly innovative and extremely energy-efficient. It is the only hot water heat pump system currently available in Australia that uses compressed CO2 refrigerant. Because of the unique properties of CO2, the Sanden Eco Plus (also known as Sanden CO2 heat pump) operates efficiently in a wide range of temperatures, and the hot water system excels in cold climates.

Because of its innovation, it has overtaken solar hot water as the best and most environmentally friendly, renewable way to heat hot water for your home.

About Sanden

Sanden is a Japanese-owned global business that has earned a solid reputation as a leader in heating and cooling technology.

With over 50 years of experience in the production and global supply of air conditioning compressors, the company applied their advanced understanding of heat transfer technologies to the home environment - resulting in the development of the Sanden Eco Hot Water Heat Pump System. This highly-innovative hot water system is manufactured in-house at Sanden's state-of-the-art factories in Japan.

Why Choose The Latest Sanden Eco Plus?

  • It has the energy efficiency of an industry-defining standard. Installing the new Sanden Eco Plus can save as much as 80% of your hot water heating cost. The Sanden heat pump system consumes less than 1 Kw of electricity to generate 5 kW of heat (COP = 5*), which equates to 20% of the energy used by a traditional electric system. Therefore, you can save up to 80% of your usual electric hot water energy costs.
  • Sanden Eco Plus is technologically innovative and has up to 50% faster heat recovery than currently available hot water heat pumps. In ambient air of 20 ºC, it takes approximately four hours to heat 315 litres of water from 17ºC to 65ºC
  • The Sanden Eco Plus system is 4x more efficient than a traditional electric water heater, has a greater first-hour rating than all heat pump water heaters, and has the fastest recovery after hot water draw.
  • The Sanden Eco Plus system uses an inverter-type compressor, DC fan motor and pump. The designminimises energy consumption, maximises water-heating capacity, and allows for faster recovery, resulting in significantly lower operating costs than electric-resistance storage water.
  • The New Sanden Eco Plus heat pump has the highest level of STC (Small-scale Technology Certificate) values of currently available commercial and domestic models on the market. Ultra-high efficiency means you get the highest hot water rebates in Australia! See our STC rebate calculator to determine how much you can receive as an upfront discount.
  • The New Sanden Eco Plus heat pump has an upgraded and longer six-year warranty. In addition, its Australian Made Stainless Steel Storage Tank has a class-leading 15-year warranty, providing you with peace of mind when installing your Sanden Eco Plus system.
  • Sanden’s extensive research and development has delivered a ‘whisper quiet’ operating noise level (37dB) that ensures both you and your neighbours’ lifestyles remain unaffected by its operation.
  • The Sanden Eco Plus comes in a split system consisting of a tank and a heat pump unit. This means it only requires a simple installation by a plumber or electrician, with no refrigeration mechanics needed. Additionally, there is no backup element or coils around the tank, so no maintenance or replacement is required.
  • No collectors need to be installed on the roof. Instead, this heat pump absorbs heat from the air and uses that energy to heat the water - a win for those wanting a clear roof for aesthetics and homeowners seeking maximum space for PV solar panels .
  • The Sanden Eco Plus has an automatic heating cycle, making it perfect for use with off-peak tariffs if preferred. It’s a method that conserves energy, saves money and reduces greenhouse gas emissions – making it better for the planet and you!

Why Is The Sanden Eco Plus Highly Acclaimed?

  • It can extract heat from the air all the way to -10 degrees and accomplishes this in a single heating stage by raising the water temp as high as 65ºC. The result is a system that requires radically less electricity to heat water and works without a backup coil in a wide range of climates compared to conventional hot water systems.
  • The Sanden Eco Plus Hot Water system is the ideal choice to replace an existing gas or electric hot water tank in any residential or multi-occupancy application. Its ability to work at low temperatures and still supply hot water at 65ºC means the hot water system can be the best hot water solution for today's modern new low-energy homes.

Heat pump water heaters commonly use synthetic refrigerants, such as R410A or R134A. Although these refrigerants do not deplete the ozone layer, they can significantly impact global warming. The CO2 refrigerant uniquely used in the Sanden Eco Plus system has an extremely low Global Warming Potential*, and CO2, a natural refrigerant that doesn’t deplete the ozone layer.

How Does The Sanden Eco Plus Heat Pump Work?

The Sanden Eco Plus heat pump works much like a refrigerator in reverse. It draws heat energy from the atmosphere and applies it to water in the tank. It contains a fan that forces air through an evaporator that contains an ozone-friendly natural refrigerant CO2 (R744).

The heat in the air is absorbed by the refrigerant, which is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped into the storage tank.

Additionally, the amount of electrical energy required to heat the water is significantly less than a conventional electric hot water system.

The Sanden Eco Plus heat pump systems are suitable for small or large households in Australia, with a high enough recovery rate to cater for a family as large as eight people. The unit is supplied as two separate components: the Heat Pump (made in Japan) and the Stainless Steel Storage Tank (made in Australia). Having two separate components allows easy on-site handling and installation , as well as flexibility on the storage tank location, which can be up to six metres from the heat pump unit.

Cost Savings Achieved By A Sanden Eco® Plus Vs A Conventional Electric Hot Water System

The 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. The customer lives in the Sydney Metro area with a family of 4 people using hot water with Off-Peak Controlled Load 2.

As can be seen, the reduction in usage achieved for the period versus the prior year was approximately 80%, while the reduction in cost for the same period was 77%, despite a change of supplier and a more expensive tariff.

Did You Know That Heat Pump Technology Is More Energy Efficient Than Solar Hot Water?

Since 2009, the Campbell Creek Energy Efficient Home Project* has compared the energy usage of three homes, each with different types of water heaters. The latest testing confirmed that the Solar Flat Panel system used 38% more energy than the Hot Water Heat Pump.
