Hot water is a daily necessity that most Kapiti homeowners only think about when it’s gone. Running out of hot water during a shower, waiting for the cylinder to reheat, or paying unnecessarily high energy bills are frustrating experiences that many households with traditional hot water tanks face regularly. Fortunately, there’s a superior alternative that’s transforming how Kapiti residents experience hot water. Infinity Gas Hot Water systems offer a revolutionary approach to water heating, providing unlimited hot water on demand while reducing energy consumption. If you’re tired of planning your day around your hot water supply or dealing with inefficient heating methods, an Infinity Gas Hot Water upgrade could be the perfect solution for your Kapiti home.

- These systems are more energy-efficient as they only heat water when you need it, potentially reducing your power bills
- Infinity systems take up less space than conventional cylinders, freeing up valuable storage in your home
- The initial investment in an Infinity system can be offset by long-term energy savings and increased property value
- Professional installation by qualified Kapiti plumbers ensures optimal performance and compliance with local regulations
Understanding Traditional Hot Water Cylinders vs. Infinity Systems
Traditional hot water cylinders have been a staple in Kapiti homes for decades. These systems work by heating and storing a fixed amount of water in an insulated tank, keeping it hot and ready for use. While familiar, this approach has several inherent limitations that affect both comfort and efficiency.
Storage cylinders can only hold a finite amount of hot water. Once depleted, you’ll need to wait—sometimes hours—for the tank to reheat. For busy households with multiple bathrooms or high hot water demand, this often means rationing hot water or scheduling showers and other activities around water availability.
These systems also consume energy continuously to maintain water temperature, even when hot water isn’t being used. This ‘standby heat loss’ contributes to higher energy bills and environmental impact, regardless of your actual hot water usage.
In contrast, Infinity Gas Hot Water systems operate on a fundamentally different principle. As continuous flow or ‘instantaneous’ water heaters, they heat water only when you need it. When you turn on a hot tap, cold water flows through the unit where it’s rapidly heated by a gas burner before reaching your tap or shower.
This on-demand approach eliminates the limitations of stored water, providing an endless supply of hot water regardless of how many showers your household takes or how much hot water is needed simultaneously. Since there’s no storage tank that needs constant heating, energy is only used when hot water is required, potentially reducing both energy consumption and associated costs.

Benefits of Upgrading to an Infinity Gas Hot Water System
Making the switch from a conventional hot water cylinder to an Infinity Gas Hot Water system offers Kapiti homeowners numerous advantages that go beyond just having more hot water available.
Endless Hot Water Supply
Perhaps the most appreciated benefit is never running out of hot water again. Whether you’re the last person to shower in a busy household morning rush or filling a deep bath after a long day, an Infinity system provides consistent hot water without limitations. This endless supply transforms how you use water in your home, eliminating the need to time showers or worry about running out during important tasks.
Energy Efficiency and Cost Savings
Infinity systems are designed for optimal energy efficiency. By heating water only when needed, they eliminate the standby energy losses associated with keeping a tank of water hot 24 hours a day. This can translate to significant savings on energy bills over time, especially for households that use hot water intermittently throughout the day.
The precise temperature control of Infinity systems also means you’re less likely to mix hot and cold water at the tap, further reducing energy waste. Many models allow you to set exact temperature outputs, ensuring you use only the energy required to reach your desired temperature.
Space-Saving Design
Traditional hot water cylinders can take up significant space in a laundry room, cupboard, or garage. Infinity Gas Hot Water systems are compact wall-mounted units that require minimal space, freeing up valuable storage area in your Kapiti home. For smaller properties or homes where space is at a premium, this compact design is particularly beneficial.
Longer Lifespan and Reliability
Quality Infinity Gas Hot Water systems are built to last, often outliving traditional cylinders when properly maintained. Without the corrosion and sediment build-up issues that plague storage tanks, these systems typically offer greater reliability and fewer maintenance issues over their lifespan.
Enhanced Property Value
Modern, energy-efficient home improvements like an Infinity Gas Hot Water system can increase your property’s appeal and value. As more buyers prioritise energy efficiency and modern conveniences, having an upgraded hot water system can be a selling point for your Kapiti home.

How Infinity Gas Hot Water Systems Work
Understanding the technology behind Infinity Gas Hot Water systems helps appreciate their efficiency and reliability. These sophisticated appliances represent the cutting edge of water heating technology, combining innovative design with precision engineering.
When you turn on a hot water tap in your home, a flow sensor in the Infinity unit detects the water movement and activates the heating process. Cold water enters the unit and passes through a heat exchanger, where it’s rapidly heated by a powerful gas burner. This heated water then flows directly to your tap, shower, or appliance.
The entire process happens almost instantaneously, with hot water typically reaching your tap within seconds. Advanced sensors continuously monitor water flow and temperature, adjusting the gas burner intensity to maintain your desired temperature regardless of changes in water pressure or flow rate.
Most models feature digital temperature controls that allow you to set precise output temperatures, enhancing both safety and comfort. This prevents scalding risks while ensuring consistent water temperature for every use. Some advanced units even allow for different temperature settings for different applications throughout your home.
The system’s efficiency comes from its on-demand operation—when hot water isn’t being used, the unit goes into standby mode, consuming minimal energy. This contrasts sharply with storage cylinders that continuously use energy to maintain water temperature, even during periods of no usage.
Installation Considerations for Kapiti Homes
Installing an Infinity Gas Hot Water system in your Kapiti home requires careful planning and professional expertise to ensure optimal performance and compliance with local regulations.
Assessing Your Home’s Suitability
Before installation, a qualified plumber will evaluate your home’s current plumbing configuration, gas supply availability, and water usage patterns. This assessment helps determine the most appropriate Infinity model based on factors such as:
- The number of bathrooms and water outlets in your home
- Typical simultaneous hot water usage patterns
- Available gas supply (natural gas or LPG)
- Suitable mounting locations with appropriate ventilation
- Water pressure considerations
Professional Installation Requirements
In New Zealand, gas appliance installations must be performed by licensed gasfitters and comply with strict safety regulations. A professional installation typically includes:
- Removal and disposal of your existing hot water system
- Installation of gas lines if required
- Mounting of the Infinity unit in an appropriate location
- Connection to existing water pipes with any necessary modifications
- Installation of proper ventilation and fluing systems
- Testing and certification of the completed installation
Optimal Placement
In Kapiti homes, Infinity units are typically installed on an external wall to allow for proper ventilation. The ideal location balances factors such as:
- Proximity to gas supply
- Minimising distance to frequent hot water usage points
- Protection from extreme weather conditions
- Access for maintenance
- Aesthetic considerations for your home’s appearance
Working with experienced local plumbers ensures your installation meets all regulatory requirements while optimising performance for your specific property configuration.
Choosing the Right Infinity Model for Your Needs
Selecting the appropriate Infinity system for your home comes down to a few key considerations. The right unit depends on your household size and hot water usage patterns—typically measured in litres per minute flow rate. A family home with multiple bathrooms will need a higher capacity model than a small household.
Consider whether an indoor or outdoor installation suits your property best, with outdoor models being most common in Kapiti for their simpler ventilation requirements. Modern Infinity systems offer various features including digital temperature controllers, frost protection, and even smart home integration—choose the features that matter most to you and your budget.
Cost Considerations and Return on Investment
While the initial investment in an Infinity system includes the unit cost, installation, and possibly gas line modifications, the long-term benefits often outweigh this upfront expense. Most Kapiti homeowners enjoy significant energy savings through eliminated standby heat losses and more efficient water heating.
The system typically pays for itself within several years through reduced energy bills, with the added benefits of greater convenience and comfort. Many suppliers offer financing options that can make the upgrade more affordable, and the increased property value provides additional return on your investment.
Maintenance and Care for Your Infinity System
Infinity systems require minimal maintenance compared to traditional cylinders. An annual professional service check is recommended to ensure optimal performance and safety. This typically includes inspection of gas connections, cleaning air filters, and checking for any scale build-up in hard water areas.
Watch for signs that service might be needed, such as temperature fluctuations or decreased hot water flow. With proper care, your Infinity system should provide reliable service for 15-20 years—significantly longer than most traditional hot water cylinders.
