Hot water · Lower Hutt
A cold shower or water around the cylinder does not, by itself, tell you to buy a new tank. Hot Water Now is the specialist hot-water service operated by Water & Gas Plumbing Ltd in Lower Hutt. Start with the fault, then decide whether a component repair, a replacement cylinder or a heat-pump upgrade addresses the problem.
No hot water? Call to explain what has happened. We’ll confirm attendance and applicable call-out or after-hours charges.
Diagnosis before replacement
Use the symptom to choose the right conversation. A repair example can show what is possible, but it cannot diagnose a different home.
For loss of heat, use our no-hot-water checks and safety advice. For water on the floor or continuing discharge, start with the leaking-cylinder guide. Do not remove covers, touch wiring or obstruct a relief outlet. Phone to confirm attendance; same-day attendance is not a promise of completed repair or available parts.
A failed component is not the same as a failed tank. In Wainuiomata, the recorded work was an element repair; in Petone, it was a cylinder-fitting repair. These are real Water & Gas jobs, not evidence that every cold cylinder or leak is repairable. Ask for the diagnosed fault and repair scope, then use the repair-versus-replacement checklist to compare tank condition, recurring faults, parts and warranty.
Repair offers have their own scope: see current component repair prices. Cylinder and pipe leaks are assessed and quoted separately, not priced by the replacement calculator.
If replacement is recommended, compare the electric and heat-pump options below, then enter the existing system and proposed choice in the replacement-only calculator. Every online quote is subject to a site visit and confirmation of installation requirements. The visit checks suitability and the full work scope before installation is agreed.
The calculator does not send an enquiry or reserve a visit. Call to discuss the result, assessment charges and timing; no repair price is calculated here.
After the fault assessment
Separate two questions: can the existing system be repaired, and will it still meet your needs afterwards? A successful component repair will not increase stored capacity. A bigger cylinder will not, on its own, resolve every supply or pressure problem.
With an electric cylinder, distinguish a heating or supply fault from deterioration of the tank. If a repair is practical, weigh the diagnosed work, compatible parts and applicable warranty against the tank’s condition and any recurring faults. If hot water routinely runs out, describe when it happens: demand and recovery need checking before choosing a larger replacement.
Identify whether you have gas continuous flow or gas storage before comparing a repair with conversion. Keep appliance diagnosis separate from the cost of changing technology: supply, flue or ventilation, location and the appropriate authorised gas work need assessment. The electric like-for-like price does not apply to a gas conversion; use the supported heat-pump path only when its eligibility is confirmed.
A heat-pump upgrade changes how stored water is heated; it is not a repair for an existing cylinder fault or a room-heating installation. Before choosing it, check whether the proposed position provides the required airflow, drainage and electrical supply, and whether recovery, noise and access suit the household. An existing cylinder cupboard is not automatically suitable. Running costs depend on use and conditions. See the Panasonic PHE-30ABR 300L installed package and check your upgrade quote.
180L & 300L electric / Panasonic, Haier & Rinnai heat pumps
Start with your busiest hot-water period, not a fixed people-per-cylinder rule. Capacity does not guarantee a particular number of people or showers: shower flow and length, baths, overlapping use, incoming water temperature and recovery between uses all matter.
Every package price below is subject to a site visit and confirmation of installation requirements. Amounts are NZD. We confirm suitability and any other work in your quote before installation is agreed.
Keep a suitable existing setup
$3,600 + GST $4,140 incl. GST
Same-location, like-for-like 180L mains-pressure replacement. Subject to a site visit and confirmation of installation requirements. Includes new valves, electrical reconnection and old-cylinder removal/disposal.
If your existing 180L cylinder generally meets demand and now needs replacement, this may be a straightforward option. If hot water regularly runs out, first assess the fault and usage rather than assuming another 180L will solve it.
Peak use and time to reheat between showers; access, pressure, connections and available electrical supply. This package does not cover relocation, low-to-mains conversion or a different size.
More stored hot water
$5,450 + GST $6,267.50 incl. GST
Proposed inside or outside installation, including relocation. Subject to a site visit and confirmation of installation requirements. Model suitability and the included installation work are confirmed at the visit.
A larger stored reserve may help with clustered showers or baths when 180L is not enough. More storage does not automatically mean faster recovery; the element, supply and use pattern still matter.
Room for the larger cylinder, a suitable base and service access, pipe routes and electrical requirements. Our advertised external option is the Rheem MPSS 32530015; not every 300L model is outdoor-suitable, and the calculator does not select a brand. Electrical upgrades or all relocation work are not automatically included.
Change how the water is heated
$6,699 + GST $7,703.85 incl. GST
Panasonic PHE-30ABR all-in-one. Subject to a site visit and confirmation of installation requirements. Includes the unit, plumbing, electrical work and old-cylinder removal.
For a household considering a different water-heating method, this unit transfers heat from surrounding air into stored water. Compare your daily demand and recovery needs as well as the upfront price; running costs depend on conditions and use, not capacity alone.
Manufacturer clearances, airflow, drainage, noise near bedrooms or neighbours, electrical supply and access. An enclosed cylinder cupboard is not automatically suitable. A 300L heat pump and a 300L electric cylinder need not recover at the same rate.
Converting from gas adds $300 + GST ($345 incl. GST): total $6,999 + GST ($8,048.85 incl. GST), subject to the same site-visit condition. See the Panasonic package.
Another heat-pump choice
$7,749 + GST $8,911.35 incl. GST
Subject to a site visit and confirmation of installation requirements.
330L rated storage · R290 refrigerant. Compare this with the 300L Panasonic if additional stored water and app control suit your routine. Check access, airflow, condensate drainage and electrical requirements; cabinet dimensions are not the full installation footprint.
Online price is for an upgrade from known electric or gas hot water, with known current capacity, mains pressure and the same location. Relocation, an existing heat pump or uncertain details need assessment.
Gas conversion adds $300 + GST ($345 incl. GST): total $8,049 + GST ($9,256.35 incl. GST). Full work scope and supply availability confirmed at the visit; no additional work is assumed included.
Another heat-pump choice
$7,749 + GST $8,911.35 incl. GST
Subject to a site visit and confirmation of installation requirements.
340L storage · R290 refrigerant. Primarily designed for outdoor installation. An indoor proposal needs specific assessment, not an assumption that a cupboard is suitable. Check airflow, service clearances, base, drainage, water quality and electrical supply. The removable head belongs to the HydraHeat system, not an arbitrary existing cylinder.
Online price is for an upgrade from known electric or gas hot water, with known current capacity, mains pressure and the same location. Relocation, an existing heat pump or uncertain details need assessment.
Gas conversion adds $300 + GST ($345 incl. GST): total $8,049 + GST ($9,256.35 incl. GST). Full work scope and supply availability confirmed at the visit; no additional work is assumed included.
Tell us how many bathrooms are used together, shower duration, baths, when hot water runs out and how soon it is needed again. If safely visible, note your current model, capacity and pressure. We assess recovery and the proposed location before recommending a size or technology.
Online price eligibility: 180L is for an existing 180L mains-pressure electric cylinder in the same location. The 300L electric path requires an existing electric storage system, known capacity, mains pressure and a known inside/outside destination and location choice. Panasonic pricing requires a known electric or gas system and capacity, mains pressure and the same location. Unknown details, existing heat pumps, pressure changes and unsupported configurations go to assessment, not an invented package price.

Hot-water cylinder replacement cost
There is no single installed price that fits every home. We assess your existing system and explain the replacement scope before you approve a quote. Assessment and call-out charges are separate from an installed-cylinder quote.
180L mains-pressure electric: $3,600 + GST ($4,140 including GST). Standard like-for-like replacement in the same location, including new valves, electrical reconnection and removal and disposal of the old cylinder. This package does not cover relocation, low-to-mains pressure conversion or a change of technology.
300L mains-pressure electric: $5,450 + GST ($6,267.50 including GST). For proposed inside or outside installation, including relocation, subject to a site visit. The visit confirms model suitability, access, connections and the work required; do not assume every cylinder is outdoor-rated or that electrical upgrades are included.
Panasonic 300L heat pump: $6,699 + GST ($7,703.85 including GST). Includes the unit, plumbing, electrical work and old-cylinder removal. The approved gas-conversion adjustment is $300 + GST; eligibility and any other work are confirmed at the site visit.

All online quotes are subject to a site visit and confirmation of installation requirements. Use the replacement calculator to check the approved selection rules. Unknown systems, unsupported configurations and additional work need an assessment and an agreed quote, not an assumed package price.
Call 022 078 1825 to arrange a replacement assessment. If the cylinder may be repairable, see component repair prices first; repairs are separate from the replacement calculator.
A like-for-like replacement in an accessible location has a different scope from moving a cylinder, changing water pressure or switching to gas or heat pump hot water. Capacity, household demand, access for removal, pipework, valves and the condition of existing connections all matter.
Electrical supply changes, gas connections and flue work, drainage, mounting requirements and any necessary approvals can add work. Urgency and parts availability also affect the options and timing. We confirm assessment or call-out charges before arranging the visit.
Ask us to confirm what is included, excluded or an allowance, so you can compare the full installed scope:
These are items to confirm in your quote, not a promise that every item is included in a standard package.
Have your suburb, household size and number of bathrooms ready, plus the existing model and capacity if safely visible. Tell us about access, leaks and whether you want a like-for-like replacement or to compare systems.
Call to arrange a site assessment. For an active leak or loss of hot water, explain the fault when you call. An assessment visit does not reserve a completed installation; scope, price and timing need confirmation.
Keep away from leaking hot water and wet electrical equipment. Do not remove covers, touch wiring or repeatedly reset a tripping circuit. If you smell gas, leave the area without using switches or phones there; call your gas emergency provider from safety. For immediate danger, call 111.
Read our full safety advice or discuss a repair before deciding to replace. Attendance and charges are confirmed by phone.

Good to know
Compare the approved 180L and 300L electric, Panasonic 300L, Haier 330L and Rinnai HydraHeat 340L packages in the replacement calculator. Eligibility depends on your selections; unsupported or uncertain configurations need an assessment. Every calculated quote is subject to a site visit and confirmation of installation requirements.
Ask what has actually failed and whether the tank remains serviceable. Compare the repair scope, recurrence, compatible parts, applicable warranty and whether the repaired system will meet your needs. Age alone is not a universal replacement cutoff. Our repair-or-replace guide explains the questions to take to an assessment.
We can assess that with you. A conversion may need supply changes, new pipework, a different location and electrical or gas work. Space, ventilation, drainage, noise and approvals matter. We explain those requirements in the quote rather than assuming every option fits every home.
The Panasonic PHE-30ABR 300L package is $6,699 + GST installed ($7,703.85 including GST), subject to a site visit and confirmation of installation requirements. It includes the unit, plumbing, electrical work and old-cylinder removal. The site visit confirms whether the package suits your home and identifies any other requirements for an agreed quote before work starts.
The approved Panasonic, Haier and Rinnai heat-pump packages each add $300 + GST for a gas conversion, subject to a site visit and confirmation of installation requirements. Select your current system and preferred brand in the calculator. The visit checks the gas work, location, water connections and electrical supply; uncertain configurations remain assessment-only.
Capacity alone does not decide suitability. Tell us how many people and bathrooms use hot water, when showers overlap and whether your current system runs out. At the site visit we assess recovery needs, access for moving the old and new units, the available space and manufacturer-required clearances, airflow, drainage, electrical supply and noise near bedrooms or neighbouring properties. An enclosed cylinder cupboard is not automatically suitable for an air-source unit. Call to arrange a site visit ↗ to confirm the location and installation requirements, not a completed installation.
Confirm who can approve the work, the agreed model and scope, access arrangements and the expected interruption to hot water. For a rental, coordinate the owner or property manager's approval and tenant access before the visit.
Ask the installer to assess the route for moving the old and new units, including doors, stairs and the proposed space. Tell us about restricted access, pets and any household needs affected by the interruption. Only clear everyday belongings where safe; do not move the cylinder, disconnect services or remove covers yourself.
Confirm removal, reconnection and any additional work against your particular quote. This checklist does not add inclusions to a package or promise an installation duration. Online prices remain subject to a site visit and confirmation of installation requirements.
This is a checklist of matters to confirm, not a new warranty or a promise of free follow-up work. For Hot Water Now enquiries, call 022 078 1825.
Tell us how many people live there, the number of bathrooms and when showers or other hot-water uses overlap. Storage capacity, recovery rate and simultaneous flow demand all matter; we assess these against the available supply and space.
