Gas Hot Water Costs in {city}
Gas hot water system costs in New Zealand include gas continuous flow (califont) units at $2,000 to $4,500 installed. A basic 20-litre-per-minute unit costs $2,000 to $3,000 installed. A premium 26-litre-per-minute unit with temperature control costs $3,000 to $4,500. Gas storage cylinders (135 to 180 litres) cost $2,000 to $3,500 installed. Gas califont repairs cost $150 to $400. Gas hot water running costs are typically 30 to 50 percent lower than standard electric cylinders.
Continuous Flow vs Gas Storage
Gas continuous flow (califont) systems heat water on demand — you never run out of hot water. They are compact, wall-mounted, and energy-efficient because they only heat water when you need it. Gas storage cylinders heat and store a tank of hot water, similar to an electric cylinder but faster recovery. Continuous flow is the more popular choice in New Zealand because it provides unlimited hot water, takes up less space, and has lower running costs. The main consideration is flow rate — ensure the unit is sized to supply your peak demand.
Sizing a Gas Continuous Flow System
Gas continuous flow units are rated by litres per minute (LPM) of hot water delivery. A 20 LPM unit is suitable for one to two bathrooms. A 26 LPM unit handles two to three bathrooms. A 32 LPM unit is for large homes with three or more bathrooms. For simultaneous use (two showers running at once), you need a higher flow rate. Your gasfitter will calculate the right size based on the number of outlets and expected simultaneous use in your Christchurch home. Popular brands include Rinnai, Rheem, and Bosch.
Regulations and Installation
Gas hot water installation must be done by a gasfitter registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB). The installation must comply with NZS 5261 (Gas Installation). Continuous flow units require a gas supply, water connections, an exhaust flue, and in some cases an electrical connection for electronic ignition. A Gas Safety Certificate must be issued after installation. Outdoor units do not need a flue but must be positioned with adequate clearances as per the manufacturer's specifications.
