A homeowner turned to Reddit for a reality check after being told their heat pump hot water system "needs replacement" and was quoted $5,000 for a new unit.
The responses pointed to a far cheaper possibility than replacing the whole unit: a failed start capacitor.
Here's what to know
The issue came up in a Reddit post on r/AusRenovation, where the homeowner wrote, "My unit has the compressor trying to start, but not being able to. A guy came here and said it's gone and needs replacement." They said the quoted replacement was an Evo270-E for $5,000.
A user who said they owned the same model said, "Normally it's just the capacitor," and suggested getting another opinion. In a separate exchange, when someone asked how old the heat pump was, another Redditor replied, "04/09. Date is on the unit."
More background
The thread also included a couple of price points for comparison. One commenter said they had replaced an older tank with an Evo270 for $3,200, while another said they paid $6,100 in Victoria for a 106-gallon (400-liter) stainless steel tank using the non-Wi-Fi controller.
Another commenter wrote, "As mentioned it's most likely just the start capacitor stopping it from running," suggesting the compressor itself may not be the problem.
What can be done?
Before approving a $5,000 Evo270-E replacement, it may be worth getting another assessment. In the thread, two commenters flagged the start capacitor as a likely culprit when the compressor won't get going, and one explicitly recommended a "second opinion."

That kind of control could matter for people in situations like the one described in the thread, especially because one Evo270 owner said they run theirs "during the day mostly from my solar." Aligning hot water production with solar generation or lower-cost electricity hours can improve the value of a replacement.
Homeowners facing a major quote should compare both diagnoses and features. Reviewing another assessment, checking whether a capacitor has been ruled out, and looking at options such as Cala can help clarify whether the best move is a simple fix or a smarter long-term upgrade.
