Keep your hot water heat pump running efficiently and heating water reliably.
Hot water heating is around a third of the average New Zealand power bill, and an unserviced hot water heat pump works harder to keep up. MiHT checks the outdoor unit only, cleans the coil and filter, and hands you a written condition report. Cylinder and plumbing work stays with your licensed plumber.
Your hot water heat pump gets a professional service from a company that doesn't sell or install new units.
MiHT is right for you if...
What your hot water heat pump service includes
A hot water heat pump that's never been serviced works harder than it needs to. Dust and debris build up on the coil and reduce how efficiently it draws heat from the air. Here's what your service covers and why each part gets attention.
The coil
The coil is where the unit draws heat from the outside air. Dust and debris build up on it over time and make the unit work harder to reach the same water temperature. It's cleaned on every visit.
The fan and airflow
The fan moves air across the coil. It's checked for damage and wear, and the space around the unit is checked to make sure air can move freely in and out.
Electrical connections and controls
Terminals are inspected, contacts are cleaned and tightened, and the controls and thermostat are checked to confirm they're operating safely and correctly.
Operation test
The unit is run through a full operation test, water temperature is checked, and system settings are reviewed before the visit is complete.
The MiHT Care Protocol.
Every MiHT visit follows the same five-stage process. It was built around a gap we kept seeing in the industry: homeowners paying for a service with no way to know what they actually got, or whether their systems were any better for it.
PLAN
Tell us which units you want serviced and how many. Your price is calculated instantly.
You see exactly what is included and what it costs before you confirm anything.
Pick a time that suits you and book it yourself. Any time of the day or night.
UNCOVER
Before any work starts, the unit is photographed and its condition recorded. That starting point is what lets us show you, at the end of the visit, exactly what the service achieved and what, if anything, still needs attention.
RESTORE
Your service follows a documented checklist built on industry best practice. The hot water heat pump unit's coil, fan and outdoor components are cleaned thoroughly, focusing on what drives efficiency and system longevity. The objective is simple: clear the contaminants that have built up since install or the last clean, so your system runs the way it was designed to.
REVIEW
Once the work is done, you receive a written condition report with before and after photos of the unit. The report notes what was found and what was addressed, so the improvement is documented. Any issues that need attention are noted clearly, whether that's a repair your system needs or something to watch at the next service. It's a complete record of your system's condition, yours to keep.
PROTECT
Once your service is complete, we take care of what comes next. Annual Care Plan customers have their next service automatically scheduled. We manage the timing, send the reminders, and book the visit. For one-off customers, we send a reminder when your system is next due so you never have to remember when you last had it serviced. Either way, your system does not get forgotten.
What's included in a hot water heat pump service
MiHT services the hot water heat pump unit only. Every visit covers the outdoor unit, including the coil, fan and filter, along with an operation test and a full condition report. The same five-stage MiHT Care Protocol applies, so your service is documented from start to finish.
The cylinder, the PTR valve, the anode rod, and all plumbing connections sit outside this service. Those stay with your licensed plumber. Refrigerant work is referred to a technician holding a current RLNZ Approved Filler or Approved Handler certificate. That split is confirmed before you book, so there's no confusion about what's covered.

Common questions about hot water heat pump servicing in Auckland
How much does a hot water heat pump service cost in Auckland?
Pricing depends on your unit and is confirmed before you book. There are no callout fees and no hidden charges.
Do you repair hot water heat pumps?
The recommendation you get is based on one thing: what your system actually needs. MiHT never installs or sells new systems, which means there's no financial incentive pointing anywhere else. If a fault is found during a visit, it gets documented clearly. You'll be told what it is and what to do next.
What is a hot water heat pump?
A hot water heat pump extracts heat from the outside air and transfers it into your water cylinder, similar to how a fridge works in reverse. It uses an outdoor unit with a fan, coil, and compressor to move that heat, rather than generating it electrically like a standard element-based cylinder. Because it moves heat rather than creating it, it typically uses less electricity to heat the same amount of water.
Does a hot water heat pump need servicing?
Yes. The outdoor unit relies on clear airflow across the coil to work efficiently. Dust, leaves, and general debris build up over time and make the compressor work harder. A professional service clears that buildup and checks the unit is operating correctly, and you receive a written condition report.
What does a hot water heat pump service involve?
A MiHT service covers the outdoor hot water heat pump unit only. That includes a coil and filter clean, a fan and airflow check, an operation test, and a full condition report. The cylinder, PTR valve, anode rod, and plumbing connections are outside this service and referred to your licensed plumber.
How does a hot water heat pump work?
A hot water heat pump uses an outdoor unit to draw heat from the air and transfer it into your water cylinder. A fan moves air across a coil, a compressor raises the temperature, and that heat is passed into your water. It is different from a standard element-based cylinder, which heats water directly using electricity.
What happens if you find something wrong during the visit?
Every finding from the visit appears in your condition report with a clear action against it. Some things are taken care of on the day as part of the standard service. Some need a return visit to address properly — we will offer to book that before we leave. Some are outside our scope entirely — we document those with photographs so you have everything you need for a qualified specialist. Some are worth watching but not urgent — we note those and recheck them at your next visit.
How long does a hot water heat pump service take?
Service duration depends on the unit and how accessible it is. An estimated time is confirmed when you book.
Book your service online, 24 hours a day. Select your system type, choose a time that suits you, and receive instant confirmation. On the day of your service you will receive live GPS tracking of your technician so you know exactly when to expect them.
Can I cancel or reschedule?
Yes. You can cancel or reschedule through the link in your booking confirmation. We ask for 24 hours notice for any changes.
Are your technicians insured?
Yes. MiHT carries $2 million public liability insurance and $1 million statutory liability insurance. All technicians are background checked before working in customer homes.
What if I am not happy with the result?
We stand behind our work. If you are not satisfied with the service, contact us and we will make it right.
