  • There can be a vaierty of reasons for a leaking hot water cylinder, it could be a perished seal, a valve failing, or any number of other reasons. The impact of a leaking cylinder can be more significant than just the structual damage that it can cause to your home.

    The cost of heating your home or businesses hot water is about 30% of your power bill each month, so when your cylinder is leaking it is costing you more in both power and water.

    However, not all leaks require a complete cylinder replacement. Often a leak is less hassle to repair than you might imagine. Give us a call, or send us an enquiry and we can help you navigate what to do next.

  • Are you tired of having weak showers? We can help you find a solution that will fit your budget. Our certified plumbers and gas fitters can help you find the perfect upgrade option whether it is an entire cylinder upgrade or a booster pump, we’ll work with you to make a plan.

  • This could occur for a number of reasons, it could be a loss of power - in which case check the fuse on the fuse board is on. It might be that your cylinder’s isolation switch has been accidently turned off, or failed - in these cases a simple fuse replacement or switching back on of the isolation switch are all that is necessary. The Isolcation switch can be found next to your cylinder. Beyond these circumstances, you’ll need the services of a professional. These scenarios apply to both a hot water cylinder or a gas califont.

    If these two solutions don’t work for you and your predicament requires more knowledge, please get in touch with us.

  • As hot water cylinders age different components within them can fail or inhibit their efficiency. This can require a changing of valves, elements, thermostats or a new hot water cylinder. We work with all New Zealands leading brands, and can make a recommendation based on your situation and budget.

  • A heat pump hot water system operates a bit like a reverse refrigerator. It pulls warmth from the surrounding air, compresses it to raise the temperature, and transfers that heat into your water cylinder. This process uses much less electricity than traditional electric or gas water heaters because it’s moving heat rather than generating it.

    A heat pump hot water system is a smart, energy-efficient choice for homeowners looking to cut down on power costs and reduce their environmental impact. They use up to 70% less electricity than a standard electric water heater, and they deliver long-term savings through lower running costs.

    Heat pump systems pair seamlessly with solar power, allowing you to maximise efficiency by running off solar electricity when available. They’re designed to perform reliably year-round, even in cooler New Zealand conditions, and with some regions offering rebates or incentives for installation, the upfront cost can often be offset over time.

    Keep in mind the upfront cost can often be higher than a standard cylinder, but the energy savings usually pay that back within a few years. Heat Pump Cylinders work best when installed in an area with good airflow (like outdoors or in a well-ventilated space), and are regularly maintained.

  • Mains Pressure Hot Water Cylinders are the modern standard for most New Zealand homes, designed to deliver strong, consistent water pressure across every tap, shower, and appliance. Unlike older low-pressure systems, which rely on gravity and often struggle to keep up, a mains pressure cylinder connects directly to your home’s mains supply — so your hot water pressure matches your cold, giving you powerful, even flow wherever you need it.

    Available in electric, gas, and heat pump models, these systems can also be paired with solar power for improved efficiency and lower running costs. Built from durable stainless steel or vitreous enamel-lined steel, they’re made to last and perform year after year.

    If you’re upgrading from a low-pressure setup, the difference is night and day — better showers, faster fills, and no more juggling between taps. It’s the simplest way to bring your home’s hot water system up to modern standards.

  • Low Pressure Hot Water Cylinders are a trusted, traditional option that have served New Zealand homes well for decades. They operate by using gravity, typically with a header tank in the roof space to deliver a steady, gentle flow of hot water throughout the home.

    These systems are reliable, cost-effective, and often perfectly suited to properties or homes with classic tapware. They’re also a practical choice for smaller households, baches, or anyone wanting a simple, proven setup that’s easy to maintain.

    And while many homeowners now upgrade to mains pressure for stronger flow and compatibility with modern fixtures, there are options to help improve the pressure that are a lower cost solution than upgrading the entire hot water cylinder. Things like booster pumps can assist in increasing pressure to more comfortable levels without the cost.

    We will make a recommendation on the best approach for your cylinder, based on your needs, the space available and the price.

  • A Heat Pump Hot Water Cylinder is one of the most energy-efficient ways to heat your home’s water — using warmth from the surrounding air rather than relying solely on electricity or gas. It works much like a reverse fridge, drawing in ambient heat and transferring it into your water supply. The result is reliable hot water with up to 70% less power use than a standard electric cylinder, meaning lower running costs and long-term savings.

    Because it harnesses renewable heat from the air, it’s also a great option for reducing your household’s carbon footprint. Heat pump systems pair well with solar power, perform efficiently year-round (even in cooler climates). While the initial installation price is slightly higher than an electric cylinder, most homeowners find the energy savings pay for themselves over time.

    Like any system, there are a few considerations — heat pumps can produce a gentle hum while operating, and occasional maintenance helps keep them performing at their best. But overall, a heat pump hot water system is a smart, sustainable upgrade that delivers dependable hot water, lower power bills, and a smaller environmental impact.

  • Solar Hot Water Systems harness the power of the sun to heat your water — a smart, sustainable choice that can dramatically reduce your household’s energy use and running costs. By using solar collectors, typically mounted on your roof, the system absorbs energy from sunlight and transfers it into your hot water cylinder. On sunny days, most or all of your hot water needs can be met for free, and during cooler or cloudy periods, an electric or gas booster ensures you’ll always have reliable hot water on hand.

    Beyond the savings, solar systems are one of the simplest ways to lower your home’s carbon footprint. They’re built to perform year-round in New Zealand’s climate and can be paired with mains pressure or heat pump cylinders for even greater efficiency. While the upfront cost is higher than a standard system, the long-term energy savings — and the satisfaction of using renewable energy every day — make it a smart investment for the future.
