1 SANDEN. Leading hot water technology

2 Why consider an Air-Sourced Hot Water Heat Pump System? An air-sourced heat pump absorbs heat from the air and transfers it to heat water. It consumes minimal electricity, typically three to five times less than a conventional electric water heater. It is designed to save energy and money and reduce greenhouse gas emissions. Why purchase a Sanden Eco Plus Hot Water Heat Pump System? The superior design of a Sanden Eco Plus Hot Water Heat Pump ensures: Industry leading energy efficiency using only 20%* of the energy required by an electric storage hot water system. Innovative technology - up to 50% faster heat recovery than currently available Hot Water Heat Pumps. Perfect to use with Solar Power or Off-Peak Electricity for even more savings. Class leading heat pump warranties, backed by Sanden s 35 years of operation in Australia. Split system for ease of installation and near silent operation. How a Sanden Eco Plus System Works The Sanden Eco Plus Hot Water Heat Pump System uses a small amount of energy to move heat from one location to another. Heat is absorbed by ozone-friendly R744 (CO 2 ), a natural refrigerant which does not contribute to global warming. As the warm gaseous refrigerant circulates through the system it passes through the compressor, and its pressure and temperature rises. The hot refrigerant then passes through a heat exchanger which heats the water. The refrigerant is cycled back into the system, and hot water is pumped to the storage tank.

3 Eco-Friendly Why employ R744 (CO 2 ) refrigerant? It offers no ozone layer depletion and minimal global warming versus other commonly used refrigerants, should the system leak. It performs higher compression efficiency, with lower energy consumption, thereby allowing more heat to be transferred to the water, for less energy used (i.e. excellent thermodynamic ability). The refrigerant temperature gets very hot, very quickly, so water temperature of 60ºC, is achieved almost instantly. Sanden is the only currently available domestic HWHP in Australia, to employ ozone friendly R744 (CO 2 ) refrigerant. *Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is by convention equal to 1). A GWP is calculated over a specific time interval and this time interval must be stated whenever a GWP is quoted or else the value is meaningless. Sanden.

Sanden has 3 core businesses: 1. Automotive Air Conditioning Systems Sanden has more than 50 years experience in the production and global supply of air conditioning compressors. It currently supplies some of the world s leading automotive brands, including VW, Honda, Ford, Audi, Rolls Royce, Peugeot, Citroen, Renault, Landrover, Fiat, Mercedes Benz & Kenworth. 3. Household Living & Environment Systems Sanden has applied its advanced understanding of heat transfer technologies to the home environment, resulting in the development of the highly innovative and superior Sanden Eco Plus Hot Water Heat Pump system, which is manufactured in-house at Sanden s state of the art factory in Japan.

4 Superior Features and Benefits Unlike other hot water heat pump systems, the Sanden Eco Plus system uses a smarter split system where the heat pump unit and tank are installed separately. This allows easy on-site handling and installation, as well as flexibility of the storage tank location, which can be up to 15 metres distance horizontally or 5 metres vertically from the heat pump unit. Sanden Eco Plus Heat Pump Unit: A high Coefficient of Performance (COP=5*) results in significantly reduced energy use and CO 2 emissions. Up to 50% faster heat recovery than typical heat pumps. In ambient air of 20 ºC it takes ~3.5 hours to heat 315 L of water from 17 ºC to 60 ºC. Whisper quiet operation, with industry leading noise level of 37 db - very neighbour friendly! Simple installation by Plumber & Electrician, with no Refrigeration Mechanic required. An automatic heating cycle, which makes it perfect for use with Off-Peak tariff. Uniquely designed to operate in all climates (ie. -10 ºC to +43 ºC operating range). No backup element required. Uses unique Ozone friendly R744 (CO 2 ) refrigerant. High quality, weather resistant construction for outdoor location. 6 year Warranty provided by Sanden Envirosun Glass Lined Tank: Australian made tank modified for the harsh water found in WA 3 x tank sizes offered 250L, 315L & 400L Fitted with maintenance free impressed current anode Fully insulated for minimal heat loss. Mains pressure rated. Safety pressure and temperature relief valve supplied. 6 year Warranty provided by Envirosun. What is a Impressed Current Anode An anode is designed to protect the tank from minerals in the water. This German designed and built impressed current anode is new technology displacing a standard anode. Unlike a standard anode that sacrifices itself and needs changing at regular intervals (that s often forgot), the impressed current method is maintenance free! It s suitable for a range of hard or soft water found in WA. Source

5 Heat Pumps as an Alternative to Battery Storage When operating at peak performance, many solar PV systems generate more electricity than their household can use. When this happens, the system s inverter exports any excess electricity to the grid. In the early days of solar the majority of homeowners were more than happy to export this excess, receiving a generous feed-in tariff. Since 2011 in WA however, this feed-in tariff was reduced to just 7 cents per kilowatt hour or unit of electricity. Because homeowners are forced to purchase this same electricity back from the grid for ~26 cents per kilowatt hour when the sun isn t shining, many are unsurprisingly looking for ways to limit the amount of electricity they sell back to the grid. While doing everything you can to maximise the use of your solar electricity during the day is one strategy, alternatives like battery banks and EVs to store electricity for usage later on are becoming more popular. Although efficient, these alternative technologies can be pricey, and in terms of payback periods, may not yet stack up. This is where hot water systems like Heat Pumps come in. Using a Sanden Heat Pump as a Thermal Battery Storage By using the built-in timers, it s possible to ensure the majority (if not all) of the heating in your Heat Pump takes place during the day when your solar PV system is generating electricity. Using only solar electricity to power your heat pump will provide 100% offset. Your Heat Pump will heat water and store it in your tank for free use later on, not dissimilar to how excess electricity is stored in a battery. According to Renew Economy*, this could boost the value of your excess electricity by at least five times. This is due to: gas now costing more (per equivalent unit of energy) than what electricity retailers would pay you for your feed-in tariff, and Sanden Heat Pumps being ~500% efficient, when compared to gas water heaters which are only around 70% efficient. This graph shows typical electricity generation from a PV array (yellow) in WA over the course of a year. The minimal power consumption of a heat pump (blue) can easily be covered by power generation ensuring you don t pay a cent. And still leaves plenty of excess energy from the PV array for other power appliances around the house. A traditional solar hot water system (green) however needs an energy hungry booster that can consume more power than a PV could actually generate. Sizing Guide To maximise the benefits of your Sanden Heat Pump, operating it as a thermal battery to your PV system, it s best to size the tank slightly greater than your overall hot water usage for a 24 hour period. There are two popular modes the Sanden Eco can operate under relating to the estimated sizing table below: 1.Normal Mode - the time clock is set on install. Then at 10am every day it does its full heat cycle. It will only come on before 10am the next day IF cold water is measured at the sensor ~110litres from the top of the tank. If this occurs the unit starts generating hot water at 60 ºC straight away into the top of the tank to prevent your household running out of hot water 2.Block Out When the tank is oversized for demand it is possible to completely block out the heat pump from operating between certain hours, ideal settings for use with off-peak electricity tariff or with Solar PV generation. eg as a Thermal Battery, if you only wanted the Sanden Heat Pump to be on-duty between 9am to 5pm, the block out should be set to 1709 (The 1st two digits are when the block starts in 24 hour clock, the latter when it ends).
