Hot water heat pump systems are great for saving energy, but there’s a major problem dogging them like an overly friendly labrador that has been rolling in fish guts.\u00a0 Most warranties stink!\u00a0 I can only think of four brands commonly sold in Australia with warranties I consider close to acceptable.<\/p>\n

<\/p>\n

But have no fear, because I’m here to save you from blindly blundering into buying a heat pump with a warranty so short it could slide under a snake with its umbrella up.\u00a0 When I’m done, you’ll be able to see exactly what kind of warranty risk you’re blundering into.\u00a0 To help you out I’m going to make a ranked list of heat pump warranties from best to worst.\u00a0 You can be sure I’ll do a good job of it because everyone agrees I’m a huge… maker of ordered lists.<\/p>\n

But I’m not going to get too carried away.\u00a0 The Clean Energy Regulator lists heat pumps<\/a> from over 100 manufacturers, which is around 80 too many for me to go into.\u00a0 But many either aren’t available or have only been sold in small numbers.\u00a0 To keep things manageable, I will only rank the heat pumps on our comparison table in the SolarQuotes guide Hot Water Heat Pumps: Choosing The Right One<\/a>.\u00a0 The 16 brands on the table include all the major heat pump manufacturers currently selling in Australia.<\/p>\n

Short Warranties On Heat Pump Parts<\/h2>\n

A major heat pump warranty problem is rather than having a single warranty period, many manufacturers divide their systems into sets of components and slap a different warranty length on each set.\u00a0 And you can be damn sure the shortest warranty will be on the parts most likely to break down.\u00a0 As an example, a manufacturer could provide a 5 year warranty for the storage tank, 2 years for the sealed heat pump system, and one year for everything else.\u00a0 Some warranties may provide replacement parts longer than they cover labour costs, while some specifically exclude covering any labour costs for replacing some components.<\/p>\n

Below are the 16 brands from our heat pump comparison table, showing the shortest warranty period offered for a part or for labour costs for residential installation.\u00a0 The Thermann brand appears twice because it has considerably different warranties between its split and all-in-one models.\u00a0 Brace yourself — you don’t have to go far down the list for things to get ugly:<\/p>\n

Update 12th March 2025:<\/strong><\/em>\u00a0 I have adjusted the order of this list because it was kindly pointed out to me that towards the end of the Aquatech warranty it says they only cover external valves for 1 year after clearly stating at the start “…covers all system parts and tank in full, with any labour charges for 2 years.”\u00a0 Very sneaky.\u00a0 Hydrotherm was also moved down for doing exactly the same thing.\u00a0<\/em><\/p>\n

  1. Apricus All-in-one:\u00a0 6 years<\/li>\n
  2. Haier Monoblock:\u00a0 5 years<\/li>\n
  3. Reclaim\/Panasonic:\u00a0 5 years<\/li>\n
  4. Ecogenica:\u00a0 2 years<\/li>\n
  5. Emerald:\u00a0 2 years<\/li>\n
  6. Solahart Atmos Eco:\u00a0 2 years<\/li>\n
  7. Thermann Split:\u00a0 2 years<\/li>\n
  8. Aquatech X6:\u00a0 1 year<\/li>\n
  9. Enviroheat:\u00a0 1 year<\/li>\n
  10. Evoheat:\u00a0 1 year<\/li>\n
  11. Hydrotherm:\u00a0 1 year<\/li>\n
  12. iStore:\u00a0 1 year<\/li>\n
  13. Quantum:\u00a0 1 year<\/li>\n
  14. Rinnai Enviroflo:\u00a0 1 year<\/li>\n
  15. Stiebel Eltron WWK:\u00a0\u00a01 year<\/li>\n
  16. Rheem Ambiheat:\u00a0 1 year<\/li>\n
  17. Therman All-in-one:\u00a0 1 year<\/li>\n
  18. Sanden:\u00a0 0 years<\/li>\n<\/ol>\n

    Of the 18 listed, only 3 provide warranties covering everything, including labour, for 5 or more years.\u00a0 The best the next 4 can manage is 2 years, and then there are 10 that cover everything for only a single year — a length of time not nearly long enough for a pricey household item that should provide years of trouble-free service.\u00a0 The very worst on this measure is the Sanden heat pump that offers a 1 or 2 year warranty on valves that’s only for parts with provision made for labour.<\/p>\n

    If you want a decent warranty, the top 4 are the only options.\u00a0 With any others, you run a real risk of having no warranty cover if it fails after only 2 years.<\/p>\n

    Heat Pump Warranty Components<\/h2>\n

    Before I consider full warranties rather than just their shortest parts, I’ll describe how warranties that don’t cover everything equally — which is most of them — generally break heat pump parts<\/a> into three categories:<\/p>\n
