Hot Water Cylinder Repair, Replacement and Installation in Auckland
Mr Plumber are Auckland hot water cylinder specialists. We supply, install, repair and replace electric hot water cylinders, manufactured to meet New Zealand's energy performance standards.
Most models are rated at a maximum of 1000 KPA and 1400 KPA pressures and can deliver more than 40 litres of heated water a minute, which is enough to meet the needs of most households. Mains pressure cylinders can run on both mains and low pressure systems.
Standard sizes range from 15L to 400L. Current insulation standards keep the optimum temperature longer, saving you energy and electricity costs.

We service, repair and replace every major hot water cylinder brand sold in New Zealand, including Rheem, Bosch, Rinnai, Mico and Reece cylinders. Whether you have an electric mains pressure cylinder, a low pressure cylinder or a gas storage cylinder, we will find the right replacement and have it installed quickly.
If you are not sure which size or model suits your home, we will talk you through the options in plain English so you can choose with confidence.

A heat pump hot water cylinder uses a refrigeration cycle to pull warmth from the surrounding air, which makes it about three times more efficient than a standard electric element. For most Auckland households that means lower power bills and a smaller carbon footprint, with the same reliable hot water you are used to.
We supply, install and replace heat pump hot water cylinders from the leading New Zealand brands, and we will tell you honestly whether the upfront cost makes sense for your home or whether a standard cylinder is the smarter call.
Hot water cylinder valves include an inlet isolating and non return valve for both low and mains pressure, a reducing or limiting valve to keep the supply pressure to a pre set maximum, and a temperature relief valve to make sure the water does not exceed 99 degrees C if the thermostat fails.
A cold water relief valve is fitted to the inlet to relieve cold water under normal thermal expansion, saving energy. A tempering valve mixes heated water and cold water to deliver tempered water at around 55 degrees C to your hot tap. For solar hot water systems, we fit a solar control valve specifically designed for use in New Zealand.

We carry the common sizes on the van and we know the difference between a faulty element and a dead cylinder, so you do not pay for a replacement you did not need.
Often it is a faulty element or thermostat, not a dead cylinder. We will diagnose it on site so you do not pay for a replacement you did not need.
If your cylinder is past it, we carry common sizes on the van. Many replacements are done same day so you are not showering at the neighbour's tomorrow.
From 15L for a sleepout to 400L for the big family. We help you pick the right size and pressure rating instead of guessing.
Hot water has to be stored hot to kill bugs but delivered safe at the tap. We fit and adjust the tempering valve correctly so nobody gets scalded.
All three. We will talk through running costs, install costs and how each suits your home before you commit.
Cylinders are covered by the manufacturer warranty and our installation is guaranteed. If the cylinder is faulty later we come back and sort it.

"The team was able to answer immediately and get a plumber on site in 3 hours. And I said it wasn't a rush. Fixing the issue required a spare part. They keep me advised of progress in getting it. A perfect job of communication and managing expectations. A few days later I noticed a small defect. Again, they had it fixed in a few hours. You are a Company of Heroes!"

Hot Water Cylinders often goes hand in hand with the work below. One local team, one quick call.

Power prices have risen 21% over the past three years. If you have an ageing low pressure cylinder sitting in your airing cupboard, switching power plans will not deliver the savings you expect. The cylinder itself is the problem.

One grey polybutylene fitting, weeping behind a Remuera wall for weeks. The pipe was installed in 1984. We have been replacing more of these every year, and the failures are no longer occasional.
