    Stiebel Eltron 302L Heat Pump Hot Water System WWK
    We have enjoyed over 10 years of low cost, maintenance free and never ran out of hot water with our Stiebel Eltron 302L Heat Pump Hot Water System in our previous property. Recently re located to a property which had instantaneous gas hot water and cooktop. After 2 months we decided to ditch the gas hot water, due to cost of gas and purchase another Siebel Eltron Heat Pump. It was an easy change over for the plumber and improvements on our last model include: A user friendly LCD screen helps you operate the appliance and shows at a glance how much mixed water is currently available. It is also ready to connect to your solar system to use “free” energy. It is quite when operating, has a superbly insulated cylinder giving hot water when required and maintenance free due to its impressed current anode. Another step in our self sufficiency journey, making good use of our solar production and looking forward to another 10 years plus of ample hot water delivered by renewables and with extremely low maintenance.

    the concept makes sense
    The running noise is quite obvious - moeso if you put a small awning over the top (our neighbour did this) - so if you are putting it near someones bedroom, consider making it a daytime heating option (not off peak). Cost wise - you are still heating water to sit in a tank all day, but we have found the distance from tank to shower - the water is still hot (unlike previous instant hot water). We live coastal & 12mo later theres no sign of weathering, but we have it on the shaded side of the house (didn't want to replumb to house to move it to a sunny location to make use of the heat pump).

    Questions & answers

    Can this pump work with a solar panel or solar battery? Anonymous · 2025-01-05
    Hi there, Thank you for your question. According to the specifications for this water heater, it is compatible with solar panels, however, this would also be dependant on the solar panels you have being able to provide enough electricity. Hope this helps. Kind regards, Appliances Online Adam Vaccaro, Appliances Online
    Who installs on arrival? Anonymous · 2024-02-18
    Hello Hesse, we do not offer hot water system installation. You would need to organise a local hot water installation service. Kind regards, Adam from Appliances Online. AdamD, Appliances Online
    Hi, can you advise if this model has the smart element? Bubs · 2023-09-10

    Would my plumber provide the STC rebate on installation? Wombat22 · 2023-03-16
    Good Morning, Thank you for this product question, normally this is taken care of by the installer however you would need to chat with them prior to the installation and get a few quotes for your installation, I am aware that there is no standard this may change from state to state normally the installer will take ownership of this for you. I would get at least 3 quotes and compare these and ask them about the STC installation rebate and procedure. I hope this information will assist you when shopping here with us at Appliances Online.
