Hot Water Services in Auckland: Repairs, Replacements and Installs
Hot water services cover repairing, servicing, replacing and installing the cylinder or heater that supplies your home or business. B&B Plumbing has done this across Auckland since 1975 on electric, gas and heat pump systems. We’re authorised service agents for Rheem and Stiebel Eltron, and we take calls 24/7 when hot water fails at night or on a weekend. Call 0800 579 7316 or enquire online.
Hot Water Systems We Install and Service
▸ Electric storage cylinders: low-pressure and mains-pressure.
▸ Gas continuous flow: instant hot water units fitted inside or outside the house.
▸ Gas storage systems: free written quotes for replacements.
▸ Heat pump hot water: storage units and split systems. See our heat pump page.
We also diagnose and repair faults, replace cylinders like-for-like, upgrade valves, and move customers to a larger or more efficient system. Maintenance includes anode replacement and filter cleaning on heat pump units.
Repair or Replace Your Hot Water Cylinder?
Repair makes sense when the fault is a thermostat, element, or valve. Replace when the cylinder itself is leaking, when rusty water comes from the hot tap, or when it has reached the age where failures stack up, commonly 10 to 15 years. A leaking cylinder body can’t be patched. We diagnose first and tell you which applies before we quote.
Choosing the Right System for Your Property
We size the system to the number of people, the bathrooms, and the pressure you need before recommending anything. Gas continuous flow gives hot water for as long as the tap runs, provided the unit suits your flow rate and the gas supply is adequate. Heat pumps cost more to install and less to run, so the payback depends on how much hot water you use. We’ll compare the options on your numbers.
Every install includes the parts that are easy to overlook: seismic restraint on the cylinder, a relief valve piped to a safe drain, and a tempering valve so water at the basin and shower is no hotter than 55°C.

Hot Water Questions Answered
Why Is My Water Pressure So Low?
Common causes are an outdated low-pressure cylinder, faulty valves, blocked pipes, or a pressure-reduced system built to an older standard. We find the cause first, then quote a repair or an upgrade.
Is a Heat Pump Hot Water System Worth It?
Often, for households with steady hot water use. A heat pump uses less electricity than a standard electric cylinder to heat the same water, but costs more upfront. We’ll compare both for your property.
Do Gas Continuous Flow Systems Give Endless Hot Water?
Yes, as long as the unit is sized correctly and the gas supply is stable. It heats water only while a tap is running, so there is no tank to run out.
Can You Service My Rheem or Stiebel Eltron System Under Warranty?
Yes. We’re authorised by Rheem and Stiebel Eltron for warranty repairs, servicing and brand-approved installations.
Do You Give Free Quotes for Replacements?
Yes. We give free written quotes for hot water upgrades and replacements, so you know the cost before work starts.
