Hot Water System Options

Electric Cylinders — The most common system in Christchurch homes. Low install cost, reliable, available in standard low-pressure and mains pressure configurations. Ideal for most residential properties.

Gas Hot Water — Lower running costs than electric. Available as storage cylinder or continuous flow (on-demand). Requires gas connection. Popular in new builds and upgrades.

Heat Pump Hot Water — Increasingly popular in Canterbury. Uses up to 70% less electricity than a standard electric cylinder. Higher upfront cost but excellent long-term savings.

Solar Hot Water — Harnesses Canterbury's sunshine to heat water. EECA-approved systems eligible for rebates. Best return on investment for owner-occupiers planning to stay long-term.

Continuous Flow — Never run out of hot water. Gas-powered, heats water only when needed. No cylinder storage losses. Ideal for large families and high-demand properties.
