The Sanden Heat Pump Advantage

Hot Water Systems and Energy Costs

An air-sourced heat pump absorbs heat from the air and transfers it to heat water. It runs on electricity but is roughly three times more efficient than a conventional electric water heater. 

The Sanden Hot Water Heat Pump is designed to save you energy and money and reduce greenhouse gas emissions.

Industry leading energy efficiency

A Sanden Hot Water Heat Pump uses industry-leading technology found in refrigeration and air conditioning units, where energy is drawn in from the ambient atmosphere and transferred into heat.

Using radically less electricity when compared to conventional hot water systems, this system will save you up to 80%* of your hot water energy costs, year after year. And no, it doesn’t involve cold showers!

How it works

Less energy, less impact on the environment, more savings.

Sanden’s Eco Plus Hot Water Heat Pump technology uses 0.84kW^ of energy to generate 4.99kW of heat – that’s 80% less energy compared to traditional hot water systems. When considering that electricity price hikes will continue to hit households year after year, it becomes the best, financially sustainable option on the market.

The system is ranked alongside solar energy in terms of environmental friendliness, making it eligible for rebates and incentives. It offers the highest level of Small-scale Technology Certificates (STCs) of any hot water heat pump system, saving you hundreds at the outset.

Peace of mind with Australia’s best warranties

The Sanden system offers the best warranties currently available for any Hot Water Heat Pump system – 6 years full parts and labour on the Heat Pump Unit and 15 years Pro Rata full parts and labour on all Stainless Steel tanks.

Innovative technology for all climates & seasons

Compared with a conventional electric system, Sanden’s Japanese-made heat pump features up to 50 per cent faster heat recovery. In ambient air of 20oC, it takes just 4 hours to heat 315 litres of water from 17oC to 63oC.

An in-built freeze protection cycle makes the Hot Water Heat Pump system suitable for all of Australia’s climates throughout the entire year.

Further, it has an automatic heating cycle, ideal for use with off-peak power and does not require a backup booster. 

All Sanden stainless steel tanks are Australian-made, fully insulated for minimal heat loss and have been mains pressure rated.
