Hot water cylinder installation and replacement
If your current setup is past its best, you’re renovating, or you want something that better suits your household, we handle hot water cylinder replacement and new installations across Hastings, Napier, and Hawke's Bay.
If you are thinking about upgrading your hot water system this can often be a great time to look at replacing any Dux Qest piping you may have present.
Choosing the right cylinder type
Most homes have either mains pressure (high pressure) or low pressure (unequal pressure) hot water. Some tapware and shower mixers are set up for one or the other, so if you want to change from low pressure to mains pressure, we’ll help you check what’s involved before you commit.
Mains pressure conversions
A lot of older Hastings homes are still running low pressure hot water. If you're dealing with weak shower pressure or your tapware isn't performing, a mains pressure conversion is often the fix. It involves replacing the cylinder and sometimes updating the pressure-limiting valves and tapware to suit.
We'll check your existing setup — including whether your current shower mixers and taps are rated for mains pressure — before recommending the switch. There's no point putting in a mains pressure cylinder if the rest of the system can't handle it.
Indoor vs outdoor cylinders
If you're upgrading to mains pressure, an outdoor cylinder is often the cheaper option — typically $500 to $600 less than an indoor installation. That's because indoor cylinders require a safe tray and drainage underneath them (it's a regulation), which adds cost and sometimes involves extra plumbing work.
A lot of customers don't realise outdoor hot water cylinders are an option — they assume anything mounted outside is a heat pump. It's not. A standard electric or gas cylinder can go outside in the right location, and it's often the most cost-effective path to mains pressure hot water.
We'll look at your property and let you know which option makes more sense.
What we will help you consider
Your current cylinder type (mains pressure or low pressure), and what you want to change, if anything
Household demand and how you use hot water
Location and access for installation (indoor or outdoor)
Whether tapware and shower mixers suit the pressure setup you’re considering
Budget and timing
Infinity gas hot water installation
Infinity gas hot water heats water as you use it, so you’re not relying on a storage cylinder. It’s also called continuous flow gas hot water. If you’re considering the switch, we can advise on suitability and handle the installation.
Infinity gas hot water can suit:
Households that want continuous hot water for back-to-back showers
People upgrading an older hot water system
Homes where freeing up space is a priority, depending on the layout and existing setup
We can help with repairs too, but this section is mainly for people planning an install or upgrade.
If you're switching from electric to gas hot water, the installation involves connecting gas supply, fitting the unit, and removing the old cylinder. We handle the full gas hot water installation from start to finish — including the gasfitting certification.
Gas-to-electric and electric-to-gas conversions
Thinking about switching your hot water from gas to electric, or the other way? We handle both. The right option depends on your property, what gas supply you have (or want), and the long-term running costs.
We'll break down the real numbers so you can make a call that makes sense — not just go with whatever sounds newest. Sometimes a standard electric cylinder is the smarter option. Sometimes gas makes more sense. We'll tell you straight.
Hot water heat pumps
A hot water heat pump uses heat from the air to warm your water. It’s an efficiency-focused option that can be worth considering when you’re replacing an older system and want to look at newer alternatives.
A hot water heat pump can make sense when:
You are replacing an older cylinder and want to consider efficiency-led options
You have suitable space and location for the unit
You want an option that can suit some households well, depending on usage and setup
A heat pump cylinder typically costs $8,000 to $9,000 installed, compared to $3,500 to $4,000 for a standard electric cylinder. The energy savings are real, but it can take around 10 years to recoup the difference. Whether that makes sense depends on how long you're planning to stay in the house and what your priorities are.
We'll give you the numbers for your situation — not a sales pitch for the most expensive option. Not sure if it’s right for your place? Get in touch and we’ll talk it through.
Hot Water Cylinder Repairs vs Replacement — A Quick Guide
If you are stuck deciding, this is a simple way to think about it. We can also help you confirm the best path once we have seen the system.
Repair is often possible when:
The issue is isolated and the cylinder is otherwise in workable condition
You have lost hot water but there is no sign of major corrosion or ongoing leakage
Pressure or temperature problems may be caused by a component that can be repaired or adjusted
The unit is not showing obvious signs of widespread deterioration
Replacement is often the smarter call when:
There is an ongoing leak from the cylinder itself, or recurring leaks that keep coming back
Corrosion is visible, or the cylinder is clearly deteriorating
You are changing household needs, renovating, or upgrading the system type
The current setup no longer suits your home, and a new cylinder or system would be a better fit
Hot water systems FAQs
Do you work on low pressure hot water cylinders?
Yes. Many older homes still have low pressure systems. We can repair and maintain them, and we can also talk you through replacement options if an upgrade makes sense for your home.
Can you install mains pressure cylinders?
Yes. We install mains pressure hot water cylinders and can advise on what is involved based on your existing setup.

Do you install infinity gas hot water systems?
Yes. We install infinity hot water systems and can advise on suitability for your household and existing services.
How do I know if my cylinder needs replacing?
If you are dealing with recurring leaks, visible corrosion, or ongoing reliability problems, replacement may be the more sensible path. If you're unsure whether you need a hot water cylinder replacement or just a repair, we can assess the system and talk you through your options.
What should I do if my cylinder is leaking, and can it be repaired?
If you can see water pooling, the leak is getting worse, or you’re worried about water damage, treat it as urgent. Avoid touching any electrical components, and give us a call so we can guide you on the safest next step.
In many cases, a leaking hot water cylinder can be repaired, but it depends on where the leak is coming from and the overall condition of the unit. We’ll help you work out whether a repair makes sense, or whether it’s time to look at replacement.
Are hot water heat pumps worth considering?
They can be, depending on your home and how you use hot water. If you are planning a replacement, we can help you weigh up whether a hot water heat pump is a good fit for your place.
