Sanden Heat Pump Installation
Sanden Eco Plus systems use a split design, with the heat pump unit and hot water storage tank installed separately. This gives greater flexibility when planning the installation, as the tank and heat pump do not have to occupy the same location.
The available space around your home, the location of the existing hot water system and the amount of hot water your household uses all need to be considered when selecting a Sanden system. The current range includes different tank capacities, from 160L through to 315L, allowing the system to be sized for different households.
MJ Air can assess your existing hot water system and the available installation locations to determine which Sanden system is appropriate for your home. This includes considering where the storage tank and external heat pump unit can be positioned and how they can be connected.
Sanden heat pumps can also work well with homes that have solar panels. The system has an automatic heating cycle that can make use of electricity generated by rooftop solar, helping homeowners use their solar energy for hot water.
MJ Air provides Sanden heat pump installation throughout Melbourne’s South Eastern suburbs and the Mornington Peninsula.

Benefits of Sanden Heat Pumps
Sanden Eco Plus systems have several features that make them different from conventional electric hot water systems and other heat pump options.
High Energy Efficiency
Sanden states that the Eco Plus uses around 20% of the energy required by a conventional electric storage hot water system. Its published specifications give a COP of up to 5.96 under specified test conditions.
Faster Heat Recovery
The Sanden Eco Plus is designed to provide up to 50% faster heat recovery than typical heat pumps. This can be useful for households with higher hot water demand.
Natural CO₂ Refrigerant
Sanden uses R744, or carbon dioxide, as its refrigerant. R744 is a natural refrigerant with low global warming potential and is well suited to transferring heat in heat pump systems.
Quiet Operation
The Sanden heat pump unit has a published operating noise level of 37dB when measured at one metre. This makes the location of the external unit an important consideration when planning an installation.
Separate Heat Pump and Storage Tank
The split system design means the heat pump and storage tank are installed separately. The tank can be positioned up to 15 metres horizontally or 5 metres vertically from the heat pump unit, providing greater flexibility when planning an installation.
316 Marine Grade Stainless Steel Tank
The storage tank is made from 316 marine grade stainless steel and is fully insulated to reduce heat loss. Sanden offers several tank capacities, including 160L, 250L, 300L and 315L.
Suitable for Solar Power
The Sanden system includes a blockout timer that can be used to control when the heat pump operates. This can allow the system to operate when rooftop solar electricity is being generated.

FAQs - Sanden Eco Plus Heat Pump Hot Water Systems
What is a Sanden Eco Plus heat pump hot water system?
A Sanden Eco Plus heat pump hot water system uses heat pump technology to extract heat from the surrounding air and transfer it to your hot water. The system uses CO₂ refrigerant technology and is designed to provide efficient hot water while reducing energy consumption.
Why is my Sanden heat pump not producing hot water?
If your Sanden heat pump is not producing hot water, check that the system has power and the controller is operating correctly. Issues such as sensor faults, electrical problems, compressor faults or component failures can prevent the system from heating. If basic checks do not resolve the issue, professional inspection and repair may be required.
Why does my Sanden heat pump hot water take longer to heat water?
Heat pump hot water systems can take longer to heat water compared with traditional electric systems, particularly during colder weather. Reduced performance may also be caused by airflow restrictions, sensor issues or problems with the heat pump unit that require inspection.
Why is my Sanden heat pump making unusual noises?
Sanden heat pump systems are designed for quiet operation. Unusual sounds such as loud humming, rattling or grinding may indicate issues with components such as the fan, compressor or other internal parts. A technician can inspect the system to identify the cause.
