What are STCs and how many do you get with your Sanden?

The purchase and installation of a Sanden Eco® Plus Hot Water Heat Pump entitles you to Small-scale Technology Certificates (STCs) – formerly known as Renewable Energy Certificates (RECs). For more information: visit www.environment.gov.au/climate-change and www.cleanenergyregulator.gov.au

The Sanden HWHP achieves the highest level of STCs of any hot water heat pump, currently available in Australia, and these are as below:

To find out which zone your postcode is in click here (note this may change so if in doubt contact the clean energy regulator for more information)

The Table below shows how many STCs are available for each Sanden model in each STC Zone 

How much are STCs worth?

STCs can be priced through the Government's STC clearing house or on the open market at places like Green Energy Markets. 

So say you bought a Sanden GAUS-250FQS and you lived in zone 4 and the current STC price was $35

The total discount you would receive would be: 34 STCs x $35 = $1,190. 

So you would receive a discount of $1,190 off the total price of your Sanden unit (note this is an example only to illustrate how STCs are calculated the actual discount will vary depending on the current STC price).

If you believe your Sanden Eco Heat Pump is not producing hot water, please try the following:

1. Unless there is water pouring (not dripping) out of the unit, do not turn the unit off and on until you've checked the clock / control panel for an error message (under our "Resources" section you can find the different error code pages to help you determine what an error code looks like). If water is pouring out then turn the unit off at the isolator and at the switchboard that circuit is attached to.
2. Pull the PTR Valve on the Tank - this confirms if there is hot water in the tank. If unsure about the water temperature use a thermometer. If water is cold goto (2) If there is 50C or so hot water in the tank then the problem is not the heat pump system) the problem is on the house side of the tank.  So the tempering valve needs to be checked for a blockage / choke, if it is installed upside down or if it has failed (they are consumable items with a lifespan of 5-6 years and they fail to safe when they fail meaning cold water).
3. Check the electricity supply - Confirm/check both (1) circuit breaker at the switchboard is ON + (2) Isolator at the HP unit is ON
4. If you see a little Red Dot in the bottom right corner, then the HP unit has power connected. For the older G2 model 2010-2016 the dot is on the controller hidden under the lid - you will need a screwdriver to remove the 4 screws from the each end of the lid.
5. Check if there are any Error Codes at the clock/computer control panel. If an error code is present, take note of the Error Code. Turn off the HP at the isolator (wait 1 minute) and turn on the HP again to see if the Error Code re-appears. The unit is functioning correctly if it blows cold air for more than 30minutes. NOTE: The unit takes about 7 minutes to start blowing cold air after power is applied.
6. If system is newly installed or new plumbing works have occurred on site confirm that the tempering safety valve (valve with orange/yellow cap) is installed the right way up with a H on the vertical barrel above the adjustable valve and a C below the adjustable valve. If the system is more than 5 years old please note these valves officially only have a minimum life span of 5 years and may need replacing.
7. Air bleed the system - Open the water drain plugs on the right hand side of the HP unit (one at a time for a good 3 minutes PER drain plug, ONE at a time). G4 units have an additional bleed port on the underside of the heat pump - please only turn this 180 degrees approx when opening it up - bleed this for 3 minutes also.  Re-set the HP unit at the Isolator.
8. Hard re-set the HP unit controller:
   1. Switch off power to the HP
   2. With power switched off press and hold down both “Up” and “Down” keys on the control panel simultaneously
   3. With the keys still pressed switch on power to the unit, the display will show “FClr” .... wait 10 seconds.
   4. To complete the reset cycle power to the unit off (wait 1 minute) and then on again.
   5. With power back on the time will be displayed (if required adjust to correct time) and the unit will run it's start up procedure.
   6. When switching power on again, the country setting "1.AU" may appear on the display. If for any reasons this setting remains on the display, simply press "Enter" and the Control Panel to confirm and HP will continue the start-up process.
9. Physical inspection of the HP
   1. Turn off the electrical isolator, to allow power to discharge, wait 5 minutes after the power is turned off
   2. Take the top panel off by unscrewing the 4x screws
   3. Check to see if any debris/foreign objects are the top of the unit
10. If an onsite plumber or electrician has a volt meter check for ~230VAC at the terminals on the side of the unit.
11. If you have an older G2 unit and E124 is displaying then the unit has been subject to either high grid voltages or has suffered a power spike. Adding a timer to the switchboard and keeping the unit powered off for more than 19 hours per day can clear the fault for each and every use. This is successful in 50% of cases however works better where it is done the first time the error is ever seen. Not where the unit has been turned on and off many times.
12. If you are getting E040 on an older G2 unit then you can clean the filter via the filter housing at the bottom of the unit adjacent the air bleed drain plugs. This may get you up and running again temporarily while you book a service. BOOK YOUR SERVICE OPTION HERE
13. For blockages in newer units a 3 way ball valve can be installed which allows the consumer to perform their own reverse flush of the system. This maintenance step is normally part of a 4 year service can then be done annually just before the air bleed is performed.

To answer the question why is my cold water valve (or ECV) on my Sanden leaking a lot what is causing this? A few elements to consider.

To protect your Sanden unit from excessive pressure there are three valves:

Valve 1. The pressure reduction valve (PRV) which is located on the water inlet to your home and is set to 500kPa. This valve is designed to keep the pressure out of any tap in your house below 500 kPa.
 

Valve 2.  The expansion control valve (ECV) which is located on the cold water inlet to your Sanden and is set to 600 kPa. This valve is designed to relieve cold water instead of hot water during the heating cycle (which increases pressure in the tank) which saves you money and protects the final valve, the PTR.

Valve 3.  The Pressure and temperature relief valve (PTR) which is located on the hot water outlet to the Sanden and is set to 700 kPa.  This valve is designed to release hot water from your tank if the pressure gets too high or the water heating cut-off fails to work.

One of the main reasons ECV valves leak water excessively (apart from wear and tear or malfunction) is excessive water pressure in the mains supply which is not properly being reduced by a PRV as it enters your house to at or below 500 kPa; in many areas the mains water pressure is 850 kPa + this is to ensure fire fighters have enough pressure to use their fire hoses properly in the event of a fire. 

Note: the Australian standard covering water pressure in the home (AS 3500.1:2018) mandates that water pressure in your home must be kept below 500 kPa as water pressure above 500 kPa  has the potential to damage valves, tap fittings, flexible hose fitting etc as the components are only rated to withstand pressures at or below 500 kPa. 

So if you notice that the expansion control valve (valve 2 discussed earlier) on your Sanden is leaking excessively chances are you have excessive water pressure at your house and your PRV (valve 1) is either not present or not working.

Either way you should get a plumber to check the water pressure in your house and make sure you have a functional PRV.  You can also buy a cheap pressure meter from a hardware shop if you want to check your household water pressure yourself:  Note your mains pressure is not constant it will change based on a number of factors including local water use, time of day, time of year or changes in your local area such as new housing being built etc.

If you have a Sanden Eco heat pump hot water system that is working but you find you're running out of hot water before your Sanden commences it's daily start up - this is most likely because you have a block out time period not suitable for your hot water load consumption.

Rectification is to change the Bllockout timer setting on your Sanden Eco heat pump (condenser unit) to either of the below Scenarios:

Most likely your current BO Timer is set up with a 5 hour period (e.g. "1611"- 11am to 4pm) - change this to either:

Scenario 1: Amend your Blockout Timer with a longer time period e.g. 0211

Keep the 'start' time of your Blockout Timer the same e.g. 11am to maximise rooftop solar PV production and change the 'end' time to e.g. 2am the next  morning.

Your BO time on the control panel should read "0211" in this scenario.

Scenario 2: Disable the Blockout Timer 

Find you're still running out of hot water? Disable the blockout timer.

Change the 'start' time of the Blockout Timer to "00" and change the 'end' time of the Blockout Timer to "00"

Your BO time on the control panel should read "0000" in this scenario.
