The Sanden Eco Plus hot heat pump hot water system is available in the following five sizes with our sizing guide below:

The same Sanden Heat Pump condenser unit is used in combination with different tanks sizes. So which tank size you would like?

When considering tank sizes - we need to consider a few factors - number of people, number of bathrooms, the heat recovery rate.

If you're using an existing hot water system for comparison - here are some comments/thoughts:

If you have an existing gas storage hot water system (e.g. 130L / 170L) - these are much smaller in capacity but they will reheat several times a day. Therefore the Sanden tank size will be larger than an existing gas storage replacement with the Sanden re-heat typically only required once per day - a good opportunity to maximise rooftop solar PV production or to utilise an off peak tariff.

If you have an existing electric storage hot water system (e.g. 400L 3.6kW unit) - these electric storage 3.6kW units recover heat at a slower rate (60L/hr) compared to a Sanden heat pump (approx. 80L/hr). Therefore a 400L electric storage hot water system would equate to a 300L/315L Sanden system in this example.

Based on our years providing the Sanden Eco heat pump hot water system - here are our tank recommendations for different scenarios (SS - Stainless Steel // VE - Vitreous Enamel):

160L SS: Only recommended for 1 person bedsits. This tank size is rarely chosen and due to its small tank size must be run in Continuous only mode (no blockout timer can be set up).

250L SS: Typically 1-3 person household with 1 bathroom. Height just under 1.5m with tank diameter 621mm.

300L SS: The Tall Slim - the most popular and best recommended tank choice. Recommended for 2-6 people. Tank diameter 580mm and tank height just under 1.9m. If no height restrictions apply, this is the recommended tank for majority of situations and considered best value for money across the tank sizes.

315L SS: The largest tank size with an additional 15L delivered hot water (5% more) compared to the 300L Tall Slim tank. Tank diameter 621mm with tank height 1.74m - this is recommended if the 300L tall slim tank is too tall for your application.

315L VE: Tank diameter 638mm with tank height 1.63m with 315L delivered hot water. This VE tank is specified for poor water quality areas - you can identify if you are in a poor water quality area via the Sanden website -> https://www.sanden-hot-water.com.au/check-water-quality/

Can I swap out my old showerhead for the Methven Kiri Satinjet Low Flow Showerhead?

In most instances yes absolutely. The Methven 5.0L/min 5 Star Kiri Satinjet Low Flow showerhead comes with a half-inch 1/2" BSP connection which is very common amongst showerheads making swap-outs very easy.

A test to confirm if you can swap out a standard rose or not from an existing shower arm is if you can twist it off yourself.

If you can't twist the head/'rose' that probably indicates the existing shower rose is integrated into the arm.

In this instance you need the Rose plus arm (either modern arm, capstan or dual pivot arm).

See below an example of an old very inefficient 15-25 L/min integrated showerhead that would need a new Rose plus arm (unscrew the entire arm off the wall). The Methven 5.0L/min 5 Star Kiri Satinjet Low Flow uses between 3-5x less water than those shower heads in the picture below, a huge water and energy saving opportunity.

You can choose any of our Methven 5.0L/min 5 star Kiri Satinjet Low Flow showerhead options from our website.

Best Electricity Rates?

You have recently installed solar PV or the Tesla Powerwall battery storage or just generally looking to get the best electricity deal for your place?

Here are a couple of recommended tools so you can choose which electricity retailer suits you. We recommend doing this check once every 6 months.

If you're in Victoria - the Victorian Government Electricity Retailer Tariff Plan Comparison Tool - https://compare.energy.vic.gov.au/. Enter your NMI and details, so long as you have a smart meter installed, the tool will look up your most recent 12 months of energy data and recommend the lowest priced electricity plan which accounts for your imported and exported energy as well as the import and export tariffs. 

If you're in SA, ACT, NSW, QLD, Tas - go to the Energy Made Easy website which is an Australian Government website maintained by the Australian Energy Regulator (AER) - https://www.energymadeeasy.gov.au/

If you're in WA - this is a Regulated Retail energy market with the supplier being "Synergy" the State Government owned entity - you can view the latest Regulated Tariff price here - https://www.wa.gov.au/organisation/energy-policy-wa/household-electricity-pricing
